The CC amps have been bullet proof. My experience with the CC Crests has been very positive.

Noted +1 for the two CC4000's thanks.

what do you guys think about RMX5050?

From what I read here the XTI 4002 gets bad sounding results from every one connecting it to the 728

your best bet is to get a used i-Tech

Going with two new 5050's would be our of budget - would a single one though be a comparable option to the CC4000's?

It's hard to beat a used ITech

Seems to be a trend here - If I have the option to buy used I will definitely check the ITechs. Thanks.

I've had great results with Peavey CS 4080HZ; been using 3 for sub duty in my house gig, and never a hiccup. Also great luck with RMX5050, not so much with Xti6000.

I am assuming you are buying one amp?

Seems to be another trend here - and that is that the XTi is something I should avoid on these 728's.

I can buy one or two amps - as long as it is close to $2000 when its said and done. A new RMX5050 means I would buy one for the two subs.

You can also look at some QSC PL's on ebay or gearsource

Will check those out too if used gear is an option. Thanks.

What are you using now? The itech 6 or 8k does sound nice on these BUT the handful of times ive used them it seems something weird always happens so personally im not sure I would trust them as my only sub amp unless you have a backup or at least something to get you through the night. What about wall power? do the venues you playing have good setups?

These SRX728's are replacing two QSC HPR181i's that were just barely enough for the higher impact gigs on this college campus. We wanted some more SPL/headroom to work with (not to mention those HPR181's don't seem to extend as low as I would like).
There are no amps powering them now - this is a new purchase not a replacement.

In terms of power - there are two primary locations they would be used - one of them is outdoors and has a 100A distro underground. The other is in a smallish auditorium with three (that are accessible easily) 20A services.

Yah, that's one 5050 for both 728's.

2 x PL4.0 will be kick ass and they are usually sold around a 1000$ each. I think it would be a bit to much for your subs but perfect in your price level.

There is also sometimes the PLX3602 seen for sale at about 7-800$ the amps ...

PL 4.0 is not too much amp, in fact, is just OK but the subs will take more.

I have used SRX728 / PL 4.0 many times at large gigs with limiters set to keep amps out of clipping (fast limiter set during show, in fact) and never damaged a cone.  If 4.0 can be had for $1000, that's a great price for a pro amp.

Currently, 4.0 is what Logic Systems here in STL uses for 728 power. The 728s normally go out with X-Array.

That is a good suggestion. Thank you.

I will have to check and see if buying used is feasible. These are for an educational institution and they may not be interested in purchasing used on their credit cards.

Check out EBay for B-stock iTechs.  There's a 4000 on there now for $1699.  I paid $1799 for my 8000.  Great amp.  No issues.  SRX 712s over 718s; 2/channel.

How doe's one PL9.0 compared with two PL4.0? there are a couple on eBay for $1250 each.

I have not used 9.0s in this application, but my gut feeling is a pair of 4.0s would be preferential to a single 9.0.

I imagine one 728 per PL 9.0 channel would be very good, similar to PL380.   I have used 380s for this and it's a great setup.

Hi doug

What limiters do you use and what type of setting you apply. Ijust got my second PL4.0. I use to have only 1 pl4 for my 2 728's.  My process is either ashley analog xr crossover or DB PA.

Situation: $2000 to power a pair of SRX728s.

Obviously I's prefer to go with something more substantial like a Macrotech - but this is all I was given to work with. I am aware two XTi4002's aren't going to drive the 728's to their full potential.

Question: Two Crest CC4000's or two Crown XTi4002's? DSP is not needed (system uses driverack PX). Weight is not a factor. Does anyone have first hand experience with the CC series?
Am I missing a better potential option?

Thanks in advance.

Now that I have all the ITech amps I need for a while, let me point out that I've bought nine ITech 8K amps in the $1700-$2250 range. They are great amps for the SRX 728s (of which I currently have six and am looking to get two more).

Just post a WTB message in the marketplace. I picked up five IT8K and one IT6K amps that way.

BTW, before getting my first two IT8K amps, I used to power four 728s cabs with four bridged XTi 4000 amps. They were always clipping. I cannot tell you how much better the SRX 728s cabinets sound with the IT8K amps over the bridged XTi4K amps. Don't go the XTi route for the subs.
Cheers,
Randy Hyde

I've used a bunch of smaller bridged amps on my 728's and the only one I could personally recommend is a good old bridged Crest 8001. FWIW I've tried a CC series model that was equivalent to a CA9 and preferred the CA9...

Seriously consider a used iTech 8000. The general consensus around here is that is one of the few amps that make 728's happy. Some of us can also provide you with presets to help users from blowing them up.
