Title: Need advice to choose PA speakers
Post by: Rick Hash on May 13, 2013, 12:16:03 PM
Hi everyone. I would like to purchase some pa speakers. Currently im considering prx 625 or 635, Yamaha dsr 215, qsc kw153, haven't decided on subs yet that would depend on the speakers I get. Can someone please suggest, or help me out with advice which ones are better. I have live x pa system, and use presonus 24.4.2 sound board. That system is fine for local bars and small parties. however, I would like to upgrade to I bit louder system for bigger events and maybe some outdoor gigs. Also, trying not to spend more than $1500 per speaker, hoping for less. Small budget...forgot to add before, powered is better for me to save up room in the van, also saves money ithink. Any advice is welcomed. Thanks

The JBL PRX6xx, Yammy DSR, or QSC KW are certainly upgrades from the EV LiveX; but it's not a large upgrade.  I would recommend looking towards the JBL STX/SRX or EV QRx neighborhood for larger events or (anything but the smallest) ourdoor gigs.

Hi Scott. Thanks for your advice. I agree with you, any of those is a good pair. I can't buy those, after considering that I would have to buy amps, cables, and racks it goes way over my budget.

How often do you expect to provide for the larger or outdoor events?  It may make more sense to run what you have currently and rent racks and stacks for the larger shows.

You can't do sound with a budget.  You have to have money.

Hi Rick,

First, you should go listen to these speakers yourself.

Second, although I have not heard the DSR215's, the DSR115 positively thunders.  To my ears, these speakers are incredibly potent and have the edge over the others in this price range.

Third, I like the PRX618S-XLF subs over any of the others including the KW181 .... but not so much that if you end up with the KW153's that I don't think you should get a matching sub.

The DSR118 isn't in the same league as the XLF or KW181.

I think that this rig could do a modest outdoor rig, but you are going to be missing some bottom.  Outdoor gigs suck up the bass.  I would recommend having 4 XLF's for outdoor gigs..... and I agree with the others that if you are attempting anything over ~ 200 outside, you are going to want more rig for the gig ..... personally, I would rent bigger gear (say 4 SRX728's and 4 SRX 725's with amps and cables) at that point.  I have seen a rig like that do justice to around 500 outside.

You CAN do sound on a budget - it's called acoustic.  As for sound reinforcement, Dick is absolutely correct.

I agree this is a good combo. However, i don't think this is significant upgrade from live x either. Just like PRX... DSR... or KW... just like someone posted in the forum in the beginning. I still consider to purchase KW153 or dsr218. I think qsc are more dependable than most. And DSRs seem like a good contender given the price and specs. Can't finish my post gtg... Edit later

Rick, the more info you can provide then better the suggestions will be:  what is the expected max coverage in persons, indoors or outdoors, is it dedicated to one band or is it for a sound company, does it need to meet riders?  So far we have: $1,500 or less per speaker and needs to fit in a van.

I can see how my lack of description doesn't allow for more concrete, detailed answers. So here is the story. I opened up my little production company, right now I mostly mix sound for  bar bands and wedding bands, with stuff in between. Usually crowds not more than 300 people. I would like to see my company grow and would like to get a pa that could accommodate open air rock shows (10000 sq feet roughly) and theatres (500-1000 seats). I understand that there are a lot to consider starting from payment of pa, brands and way of running it. So I figured I would just get a few louder speakers as a step forward. I look at KW and DSR to start with but maybe it's better to skip a step and start investing into a STX type of pa. It's much more money and I don't know if I'll get enough gigs to cover the cost. My bottom line right now is that this is a hobby and it doesn't generate much income for me. That's why I wanted to keep it simple and just kept my question to a minimum hoping to hear opinions about the speakers, not suspecting that this thread would grow into a slightly different discussion. So if anyone is not confused by now and still feels like throwing something my way I'm all ears. Thanks

It's sad that I wanted to get zxa5 in the first place. The price was to high at the time. Those are much better than I thought originally for some reasons I had different numbers in my head for that speaker. How do you think they would do with kw181 under them?

Rick, you and I are in just the same situation, however my hobby it threatening to take over.
Here is how to resolve the situation: Step one it to completely forget about ROI. Buy whay you need to get the job done, speakers, amps, trailer, tow vehicle, power distros, cables, lights, whatever it takes. Sense its a hobby think of is as if you owned a big boat... you pour $ into it for the pleasure of using it sometimes.

The next step it to look around your area and see if there is some place you can rent "racks & stacks" for the bigger outdoor shows.  This will be main speakers, subs, amps, cables, crossover, processing, often accompanied by a system tech.  You simply supply everything else.

If you are in a market where the above is simply not available or totally uneconomical due hi rental rates you get to start piecing together a festival rig.  If you want to insure a successful outcome you must have a system that will survive anything that is thrown at it: rick, country, death metal, hip hop.... to do this for 1,000 ppl outdoors takes a pretty serious amount of stuff.

I am booked to do a big party at a large campground this year. My client says I won't need the big rig because he did it with his bar rig last year and only blew up one speaker...Guess what, I have learned not to let the clients dictate what rig to bring.

Another factor is 'outdoors' can be a number is situations. An amphitheater type setting can be much easier then a flat open field. An outdoor gig in a downtown area surrounded by buildings presents it's own problems.

Personally, I don't believe simply doubling the size of you indoor rig will be sufficient... but I could be mistaken about the actual needs.

Larger shows require a system that is several orders of magnitude beyond a bar rig.  The nice part is that with larger shows come more meat in the seats (and more money to rent Enough Rig For The Gig).  Festivals and such are no place for hobbyist sound.

That would actually be quite a significant upgrade from Live X series in terms of output and sound quality.

Absolutely.  The problem is, most rigs (and all the powered MI=level stuff, IMO) are difficult to scale up or down to fit any situation.  Wen was the last time you saw 32 boxes of PRX gear on either side of a festival stage?  The requirements for doing outdoors at decent SPL, as well as providing coverage without audio smear, dictate that different types of equipment are used.  Line arrays, or very loud SPL arrayable boxes like the EAW KF series or the Danley SH or JH series, are designed to focus sound over a large coverage area and at a desirable volume level that doesn't sound terrible when cranked up.

I made a conscious decision to get a system that fit into a van, and if I ever needed a  bigger system for an event, to rent the system or pieces I needed. rather than buy and tow an extra 5000 lb of stuff around for the few times I'd really need it.  For instance we are doing an outdoor festival next month, and I'm renting extra lights and 4 monster powered subwoofers to cover the gig, in addition to what I've got.

Hi Marc-

The process of learning involves failures of materials, methods, and personnel.  It's really okay to kill a few speakers or power amps along the way; the repair or replacement costs are the tuition at Ye Olde Skool of Audio Harde KnocksŪ.  You acquire certain knowledge and experiences that cannot be communicated in print or on an internet forums.  It is not a grave moral failure.

Yeah, it sucks to figure out you need $300 worth of recones or HF diaphragms, but now you know what it takes to kill them, and how the rig sounded leading up to the moment of failure - how it sounds when it's "stressed."  One of my "system guy" tasks is determining if I can safely give a Band Engineer "a little more" HF/MF/Subs if asked, and some of what I'm listening for in the system I learned the Ye Olde Way.  The tuition continues to pay off for me.

Have fun, good luck.

That is a great post!  I know I went through my period of blowing out a few JBL 2206's, pushing them a little too hard on some new, larger gigs.  I was lucky with the HF, those 2447's are tough! Anyway, it  won't happen again.  A man's got to know his limitations(and his equipment's limitations too).

But to answer the original question, the SRX stuff is really hard to find used(I'm lookin') and the new STX line looks really good and worth the investment that you are going to have to make if you want to move up to slightly larger gigs.  There's a lot of good equipment out there but most of my experience has been with JBL, and it's hard to go wrong with it.

Can someone please suggest, or help me out with advice which ones are better. I have live x pa system, and use presonus 24.4.2 sound board. That system is fine for local bars and small parties. however, I would like to upgrade to I bit louder system for bigger events and maybe some outdoor gigs. Also, trying not to spend more than $1500 per speaker, hoping for less. Small budget...forgot to add before, powered is better for me to save up room in the van, also saves money ithink. Any advice is welcomed. Thanks

I use PRX boxes for my B rig (625, 635, about to get some 618s XLF boxes). As much as I'm a JBL house, I'd suggest the QSC 153/181 combo at this segment of the market. Smaller (but weight more) and probably going to have fewer reliability problems.

The PRX (typically) has a 90-degree coverage pattern. The QSC 153 has 70 IIRC. So the QSC will push a little deeper (though, obviously, not as wide). Outdoors, I find the PRX cabinets run out of steam really fast (my SRX "A" rig blows these guys away -- though I do use an order of magnitude more power in my SRX rig). 

I've been doing a weekly "movie nite" gig with my PRX 625 and 635 cabinets (two per side, yeah, comb filter hell) and the four of them are barely audible at the outside fringes of the audience (maybe 1,000 people show up, maybe). Keep in mind that this is with compressed recorded material. For a live show, the speakers wouldn't work at all with a crowd size like this (outdoors). I've done indoor shows with 500 people no sweat, but outside these cabinets just die off real quick (the QSCs won't be a whole lot better; it really takes a *lot* more power to do larger outdoor shows).
Cheers,

Hey !

I do not want to jump on this thread ... but I feel its pretty related. Is a rig of 8 x SRX718 with PL4.0 bridged per 2 subs (Or 4 728's) grounded and 4x QRX212's flown at about 6 feets on top of the stage is okay, in-off or way under basic needs for Metal/Rock outdoor gig for 1000 people ? The stage is an SL100. I do not think the ''room'' will be wider than the stage. FOH is at 75' Max. Would it be better to add ''delay'' boxes such EF508 or QRX115 on top of single 18 subs ?

The whole idea is if you do not need to go outdoor often, then your rig can be a lot smaller and used as delay speakers or sidefills for larger events where you rent the main sound kit. That way your stuff is used even during larger event and your ROI will be better.

For me, it is a good question too, in Fact, I started with 2 yorkville NX25's (small conference of 100-150People) Ended up with 4 because of room sizes. Then went with the QSC HPR 122i, what a nice box, still have 8 of them using them for small to medium size indoor partys, larger conferences or seminars and small events. Than got into the bi-amp world with the EF508's coupled with SRX728 Subs and now using the whole rig including the EV QRX 212 as main ( The EF508 are sometimes used as center fill or delay). It took me almost 9 years to get all of this following the need and the demand - Slowly getting more to fulfill specific needs. On larger indoor event such a rock concert of 6000 people, I rent a complete rig from larger companies, its easier and a lot more fun ! Outside is very difficult to analyse ...

I use 4 QRX212 tops over 4 LS1208 subs, with ample Crown power for the boxes. While I feel pretty good about the rig handling classic rock, jazz, R&B, and some other genres for a reasonable crowd (i.e. small festival) in a close packed outdoor environment, I am not comfortable with the system for a crowd of 1000 when working for a metal band. I would want to double my system for that show.

While the system MIGHT survive the metal show of doom, it would be running on the ragged edge all night. That isn't good for me or the client.

The bottoms could probably use more power (I use six SRX 728s driven by ITech 8000s when doing shows with 2,000-,2500). I run four SRX 725 cabinets (cross-fired, typically) bi-amped off ITech 8K + XTi2K (HF). Again, 2,000-2,500. All outdoors. Not as loud as I'd like at the back of the crowd; rip-your-ears-off loud near the stage, decent rock volume at FOH (100-125', probably 105 dB SPL).  Figure you're filling half the distance I am, so you might be okay. I'd probably want a little more on the tops, but that's just me.  Indoors, you should do great.

I use delay stacks on my larger shows. I've tried QSC KW 12" and JBL PRX 625. They were both worthless (FOH mains blew them away after 50', this is with the delays being 150-250' from the stage). A pair of SRX 725 cabinets driven by an XTi4000 amp do okay.

BUT....
The problem with delay stacks is that they really only sound *good* in one spot. Move too far away from them and the phase/delay errors start accumulating (to the point you can hear the sounds from the two different sources). Yeah, for non-critical ears (most of my audience) it's okay. Drives me nuts though and makes me think about investing in a line array (or a really great point source system, like Danley) at some point.

Outdoors is a lot easier because venue acoustics tend not to be an issue. The problem with outdoors is that you need about 4x the power as you don't have the reverberant field to back you up. I think I'm pushing the limits one can achieve with traps outdoors (2,000-2,500 people, once in a while more) as the inverse-squared law is killing me (too loud up front, too quiet in the back). I either need to fly some point source speakers (e.g., Danley SH 46) high enough that I put some decent distance between the speakers and the front row (or go over their heads and use front fill for the people up front) or I need to go to a line array where only part of the power is directed near the front and I can blast away at the people in the back.

Whatever the case, it's going to cost a *lot* of money to get anything substantially better than my current rig. For the time, I'm happy limited myself to the jobs I can do with the SRX gear.

The bottoms could probably use more power (I use six SRX 728s driven by ITech 8000s when doing shows with 2,000-,2500). I run four SRX 725 cabinets (cross-fired, typically) bi-amped off ITech 8K + XTi2K (HF). Again, 2,000-2,500. All outdoors. Not as loud as I'd like at the back of the crowd; rip-your-ears-off loud near the stage, decent rock volume at FOH (100-125', probably 105 dB SPL).  Figure you're filling half the distance I am, so you might be okay. I'd probably want a little more on the tops, but that's just me.  Indoors, you should do great.
I use delay stacks on my larger shows. I've tried QSC KW 12" and JBL PRX 625. They were both worthless (FOH mains blew them away after 50', this is with the delays being 150-250' from the stage). A pair of SRX 725 cabinets driven by an XTi4000 amp do okay.

BUT....
The problem with delay stacks is that they really only sound *good* in one spot. Move too far away from them and the phase/delay errors start accumulating (to the point you can hear the sounds from the two different sources). Yeah, for non-critical ears (most of my audience) it's okay. Drives me nuts though and makes me think about investing in a line array (or a really great point source system, like Danley) at some point.
Outdoors is a lot easier because venue acoustics tend not to be an issue. The problem with outdoors is that you need about 4x the power as you don't have the reverberant field to back you up. I think I'm pushing the limits one can achieve with traps outdoors (2,000-2,500 people, once in a while more) as the inverse-squared law is killing me (too loud up front, too quiet in the back). I either need to fly some point source speakers (e.g., Danley SH 46) high enough that I put some decent distance between the speakers and the front row (or go over their heads and use front fill for the people up front) or I need to go to a line array where only part of the power is directed near the front and I can blast away at the people in the back.

Whatever the case, it's going to cost a *lot* of money to get anything substantially better than my current rig. For the time, I'm happy limited myself to the jobs I can do with the SRX gear.

Thanks Randall !

This is pretty good information for all people like me and Rick and even you !! As far as power, here is how I power my rig :
4 SRX78 with 4x PL4.0 bridged ( thats 4000watt in each cab )
4 QRX212 with 2 x PLX3402 for mids and 2 PL1.8 for highs
2 DR260's
I can add 2 extra 728 with 2 pl4.0 ...

The stage is at 4feet from ground and the tops are at 6 feet from stage so the tops are flown at almost 10 feets from ground and people. I will use 2 HPR122i for front fill if they are worth it.
Your are probably rigth for the delay's. My idea was to put them on ST132 flown at 9-10feet, the boxes are EF508 bi-amped (Yorkville AP4040(mid) and QSC GX3(Highs).  .

I feel the same, unfortunately I do not have in off outdoor gigs to justify bigger sound rig. I tend to not go after larger events because of all the headaches that comes with it. 

But that being said, Rick I do not think any small powered cab such PRX, QSC KW or HPR is the right tool for the job unless its a small Party or basic parc sound reinforcement !

The most important thing is to know your limits before blowing your stuff and your customer confidence on you !!

This.

I blew up my share of PA learning This in the early 1980s.

I must be going through that phase now..

4000 watts into a 718s is pretty aggressive (peak power handling is 3200 watts IIRC).
4KW into a pair of 718s in parallel (4 ohms?) sounds about right.

Hello Randall, its bridged PL4.0 per SRX728 or 2xSRX718 .... even 4K seems a bit too much, limiters are set not to destroy the driver ...

Hi everyone. Thank you all for all your suggestions. Definitely helped me and will be help for the future when I want to expend my gear. Based on my needs and budget I decided to go with prx735 and prx718xlf. I believe that is a good start for large bars and some halls. Also, could add a couple more in the future if needed. With any success I will probably upgrade to stx or whatever will be on the market at that time. Unless I win a lottery... than line arrays  :)

I'm back. got my pa. prx735 and prx718. great sounding speakers. two complaints. one: fans are on all the time. even though they are not loud, however I could hear them in the theatre that I was testing them in. given it was complete silence when I noticed and there were 4 of the fans. two: big issue that I'm about to resolve (I hope). POWER SAVING MODE, WTF were they thinking!!!!!! 2-3 min after there is no signal received by the speaker it goes into power saving mode. that's all great only if it wouldn't take too hot of an input signal to start them back up. even more for the subs. I can't say how many dbs but I will say I had speaker gain set all the way up on the amp and when they finally turned back on it would be too loud for a quiet resection or some corporate event that needs music as a background noise. great sounding speakers though. and lite :)

It's really a shame that JBL didn't design this very well. The PRX600 series had a reputation of overheating, so they slapped a cheap, noisy fan on the back. This, and the low signal shutdown are common complaints with the new 700 series. Owners are told by JBL that there is nothing that can be done about either issue.
