"I just purchased 2 of the JBL SRX712M wedges, and so far, they're incredible. 800 watts, pole cups, biamp/passive switch, and 33 pounds! They are definitely the most versatile utility box/monitor you could purchase in their price range. Oh and I almost forgot, they sound amazing. Extremely smooth sound with no crazy off/on axis hot-spots. The only problem I'm having with them is projection... Instead of the sound coming from the baffleboard, it almost seems as if it's radiating from the entire box. My guys find it very weird and have mentioned that even the musicians have noticed the lack of directivity".
My feelings haven't changed, it's really weird, but they just don't project very well.

A small update to this post. I went ahead and bought 4 of the 712m's and sound quality and performance are impressive for the money. I will say that I think JBL made a mistake in making a wedge aimed for the MI market that requires so much power though. I was using MA 2402's on my old wedges with no problems. Of course they has a higher effecientcy rating than the 712m's (500W and 99db 1w 1m vs 800W 95db 1w 1m) but I really didn't take the JBL rating seriously at first and thought the crown MA 2402's would be enough for my applications. I was wrong. My MA 2402's are now MA 3600vz's. Now the wedges are happy. But what doesn't make any sense is that JBL's srx line is indeed an MI product (higher end MI product but still not considered a pro touring product). Needing that kind of power works fine for me but for those who are shopping on a smaller budget, it simply put them out of place in an MI market. Mike Russell |
I think the SRX stuff are the boxes that blurs the line between MI and pro. It takes little vision to see that the amplifier market is going to higher power switching amps, and the SRX can take it. Having components in the box that are the same ones the big dogs use makes one feel "special" even if they tweek the hell out of 'em and make 'em sound like crap.
Now the issue of getting high SPL out of a SRX setup, off two 15A breakers, that'll break the MI back.

How is everyone running these? Big dual channel amps or 2 bridged amps? Just curious, I'm thinking about a pair of SRX725's or Turbosound TXD-252. Either way, requires a big investment in power.

Bi-amp the 725.
Run 2400w into each pair of 15's
And 200w into the tops.
Running full range the 725 is 1200/2400/3600w for power.
The HF driver will take 75/150/300w in the biamp mode.
The bottom 15's deal with the same power range as full range.
4 Ohms on the bottom, 8 on top.
Crown XS900 is 2500w 4 ohm monobridge.

I also had to upgrade amps after adopting some 712's. I don't recommend these monitors for most small time bar bands unless they can afford to power them correctly. For those who can afford to power them properly, they make a great monitor, front fill, delay, small main, utility speaker, etc..

I'm intrigued by the comments on "lack directivity" - I haven't gotten that feedback (yet...). I've have gotten uniformly very positive reports from the artists - they seem to hear better and at lower SPL.
Post by: Grayson Rech on March 07, 2006, 01:24:51 PM
Last week I was able to finally hear (wasn't going to plop $900 bills based solely on a spec sheet) them at a large reputable east coast supplier. The console was an A&H GL3800 EQ'd flat running to an Itech 4000, speakers were run passive. I wish I could say otherwise but it was probably the worst sounding wedge I'd ever heard . . . like a couple of speakers mounted in a cardboard box. Sure it was awesomely lite and small but put beside a JBL Mpro 412 it was stomped on.
Now because I haven't heard any real complaints on this box from anyone here, I'm really wondering if the box was being sabotaged so to speak in favour of another box. I watched the sales rep move the NL4 from the 712 to the mpro412 and a world of difference came through. I tried a few tracks from CD and the real test of a Shure SM58 as a vocal monitor. Am I missing something or just was this a doomed test before I even got there? Just curious as to explain a box that went waaaaayyyy beyond bad sounding. This defide a "it doesn't fit my taste sounds".
I mean no offense to those giving there opinions I still look to you all for insite and experiences. However, as dave said a while back, internet can't offer what meatland can! or something like that.
Respectfully,
Grayson

I don't know why the rep would sabotage the SRX against the 412...they're both JBL products, and he should be motivated to sell the one that's 2x as expensive. Try one for yourself, with your rig, and see what you find out.

Thanks for the intel and some day I might try them out again on 100% my terms meaning a fully controlled environment.

What are the boxes made of? Light, or lightly-braced, boxes will resonate, and the result could be what John describes.

They don't exhibit any obvious/troubling resonance(s) on Smaart. Running Pink Noise and various music content on them while pre-programming the Protea 4.24 GS (using FFT) showed far fewer frequencies that needed "correcting", and to a far lesser extent than other wedges (I've now got quite a library of presets...). "Out of the box", they are flatter than anything I've previously used.
I'll ask around, and maybe crack one open to see the bracing, and cabinet construction (will post pics). Beats re-racking between gigs...
Post by: bo putnam on March 09, 2006, 10:52:30 AM
The enclosure is constructed of top quality birch plywood and coated in JBL’s rugged DuraFlex™ finish. The attractive CNC-machined, 16-gauge steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the box to create acoustical interference. The grilles are internally lined with acoustically transparent foam to provide additional driver protection and give a very professional appearance.
I'll open one up and check on the bracing question.
Post by: Tom Reid on March 09, 2006, 11:49:54 PM
The rest of the line is 15mm 11-ply birch plywood.

The 718 and 728 use 18mm 13-ply birch plywood. The rest of the line is 15mm 11-ply birch plywood. |
"SRX700 is constructed of top quality birch plywood and coated in JBL's rugged DuraFlex™ finish. Extensive use of internal braces and bulkheads makes the enclosures extremely rigid. This reduces acoustic losses caused by panel resonance. "
There is no bracing in the 712M - I wouldn't think any is necessary as the cabinet is a compact 13.75 in x 21.5 in x 10.25 in.
The real key to their light-weight are the neodymium motors, both on the 2262HPL differntial-drive woofers and the 2431H CD (3-inch). The aluminum baskets on the 2262HPL are very stout, but incredibly light, as is the motor. The baskets give great access if they were to ever need a recone, but that is pretty unlikely. Not sure I wanna try and align that triple VC anyway...
Here's a composite pic of the 2262HPL, and the EQ settings saved in my Protea RD compared to those of an EV wedge.

I think they are a great box and would definitely rate them in the pro section of JBL's line up rather than MI products
I use them for everything , Corporate speakers on sticks. Band FOH (with subs) ,
Stage Monitors etc
I Also have a VRX 932LAP FOH System & the 712's double as great monitor box to complement the VRX
Yeah you can really here the directivity of the VRX over the SRX but the SRX is still a good reasonably directional box at a great price point & compares well against other 12" products from other major manufacturers

It will work but they'll be wanting more.
If it gets loud enough for you and sounds good to you, then it's good!
Post by: Akki Serd on January 06, 2010, 02:30:30 PM
i see its 1200w 4ohm in passive mode
and xti4000 is 1200w at 4 ohm
looks like good mach?
Post by: Duncan McLennan on January 06, 2010, 05:57:09 PM
So most would recommend an amp between 1,800 and 2,400w.

Bridge the 4000 and run momo? Cross them at 90hz with a sub. They are a bit weak in the low end without some sort of sub.
I run one on a bridged XTi 2000 on each side over a 718 for smaller shows. They do sound good for waht I use them for.
Post by: Keith Clarkson on January 10, 2010, 07:23:24 PM
This delivers 650W into a single box running passive or 600w into each box if 2 boxes on one side of amp (4ohms) I work with a lot of name artists & have never ran out of headroom for stage monitors even running passive with the pickiest artists who want it "loud"
Crown amp specs are guaranteed minumum continuous power not peak power as some other amp manufacturers spec so this is working in your favour as these amps deliver the power they say they do for more than just a ms as a lot of other brand amps achieve their max rating often for only this long & cannot sustain the power.
The other great thing about the Crown XTI series is that the boxes can be pre Eq-d to be nice & flat before you start so you only have to tune for feedback/room / artist not box correction as this can be done once in factory conditions with accurate measuring equipment stored as a preset on the Amp .

Back to the SRX712M, if you run them biamped with an I-Tech 4000 or 5000 per mix they are a truly rocking box. I tour doing monitors for Thievery Corporation and we have a LOUD stage with 8 singers throughout the night. I'm usually quite happy when i come to a venue that has these. When carrying a touring rig my first choice is D&B M2s after that I'm happy to see the little SRX712M. As far as price versus performance I dont think you can beat the SRX712M. I think dealer cost is around $800 per box these days and at 38 pounds I load in by myself and I'm fine with that. Anyway, I'm buying more...
Oh and if you need just a little bit more the VRX915M is awesome too.

We've got 16 of them running passive at a national venue and they've worked great. I've mixed monitors on them for lots of bands from P-Funk to Levon Helm to Hell Yeah (members from Pantera etc...) to Jay-Z. Never had a problem. I did write in some decent parametrics on the outputs of the PM5D and I recommend a limiter if you dont have active processing. I also own 8 of them myself that I use for monitors or mains for my small sound company. Also have 2 of the VRX915M, 4 of the VRX932, 6 of the VRX918S and 2 of the VRX928. I think JBL has really done good work with this lates series of speakers. I used to not like JBL so much. I have toured quite a bit and until Paul Bowman (spelling?) wrote presets for the Vertec I hated them. I mixed on 2 good Vertec rigs out of 75 before that. One was in Latvia and the other at the Verizon Theatre in Houston. Anyway, it seems that JBL has come to play these days.

You can believe what ever you want, but if you look it up you will see that the 712M uses the same 12" woofer and 1" compression driver as a Vertec 4888.

alive and kickin'
i'm surprised no one has mentioned the weird high end thing. 'what weird high end thing, brian?' glad you asked.
i work with a small company in sterling, va and they bought 8 of these with the subs based largely on the package, which is, i'll grant, pretty sweet. stick speaker [love the dual pole mount], monitor, light, well built, etc.
but the first time i took them out i noticed this weird sound in the horn driver, kinda like a 'vibrating wax paper on a comb' thing, but much more subtle. and all the 712s had it. when i pointed it out to the company owner, he concurred. i tried eqing it out, but that just tore into the clarity of the box.
long story shorter, i used them a bunch of times after that, but it was never a pleasant experience. all i could hear was that weird sound character. drove me bananas.
i should say, this shop is almost exclusively a d&b shop, so i am used to hearing some pretty sweet speakers. still, this was a weirdness i never got over.
YMMV>
