Im debating between the IPR 4000 and the P7000s.. I can get them for around the same price, wich would be better for powering 4 T48s loaded with the Lab15

@ $549 for an IPR 4500 YOu could get into a used XTI 4000 for that which would better serve your needs.

the xti would be used and heavy

Do you already have DSP?

And the p7000s weighs 25lbs without dsp vs 18.5lbs for crown xti at exact same price even new.

Clearly the peavey weighs less so if you are basing it only on weight that is the clear winner. Dollar for feature though Crown XTI is the winner.

XTi 4000 - 18.5 pounds (8.4 kg) power @ 4 Ohms - 1200 Watts
P7000 - 26.5 pounds (12 kg) power @ 4 Ohms - 950 watts
Peavey IPR4500 - 6.2 pounds (2.8 kg) power @ 4 Ohms - 1350 Watts

The Peavey IPR would be the choice for me. The IPR with DSP is around US$700. The Crown is not available new anymore. The new Crown XTi 4002 is around US$1000. The Yamaha P7000S is around US$750.

My personal preference would be the Crown. For the price & weight, the Peavey is attractive, but unproven. If I could get a much better deal on the IPRs, I'd take a chance with them. The Yamaha would make a nice back up amp.

I've got a handful of gigs in with IPR 3000's now. So far so good.

I just got two of my subs and an IPR3000 back from a dude that rented them this last weekend. He's the sound guy for a band and needed two more subs for their bigger gig. He was interested in how the IPR compares to his other amps on subs, and he was surprised to find the IPR3000 clearly sounded better than a QSC RMX2450 on the subs! I was surprised to hear this too since I always thought people love the old RMX amps on subs?? What does that say about the IPR then?

I know a lot of people here are fans of the XTi's, but trust me when I say they are no good on subs. I used two xti4000's on subs for a couple of years and the moment I turned on the IPRs I heard the difference.

Given all things equal between the two amps, (Voltage, EQ and THD), what difference could you actually "hear"?

I don't think the DSP versions of the Peavey IPR series are out yet. Or at least not on the larger models.

We need to have a meetup somewhere and shootout XTi vs IPR vs iNuke sometime in the offseason!

What difference did you hear?

Yes, please, what sort of difference? I'm evaluating sub amp purchases, and I've been eyeballing the IPRs pretty hard.

Any information you could provide would be helpful.

I just took a closer look at the IPR-DSPs' features, and one important thing that I noticed was that you can use the EQs without the need for a laptop (unlike the XTis). This may be a moot point for some, but very important to others. For instance ... bass guitar > preamp > IPR DSP ... fully functional biamped bass rig.

You do not need a laptop/computer/USB control for the XTi, it's just easier & more convenient, for me, to control them. You can access everything by the front panel, just not as easy.

BTW, your bass rig example can be done be done with an XTi. You can set your crossovers and base line EQ by computer via USB, then use the preamp EQ to make on-the-fly adjustments. I'm not bashing the Peavey or the Yamaha, it's just some folks on here think, and comment that the XTi can only be controlled via USB, and that simply is not true.

I don't think the Peavey IPR DPS are even out yet are they? I wish Peavey and Behringer would hurry up and release their D class DPS amps. I need an amp soon and like the idea of a super light amp.

I'm about to build 4x T30's, and i'm interested in the IPR series amplifiers.

The problem is that I'm in Sweden and Thomann only delivers IPR 1600's for the moment, how will this amp serve as sub duty with 4x T30(3012LF)?

I've read it's got about 50 vrms on the output, which is where u're supposed to limit the 3012LF's.. I don't really understand how the vrms is affected by different ohm loads and so forth, will 50 vrms mean 25 volts to every sub(if 2 used) no matter of impedance load?

Thanks!

If you run everything in parallel , a 50V output from the amp will mean 50V at every speaker, regardless of total impedance.
