I am trying to decide on a single amp option to power up to 6 dr200's with the 16 ohm delta pro and up to 4 36" T48's
It seems that an xti 4000 would not really be a good choice as current demands jump drastically below 4 ohms with an 1/8 pink noise input (something crown claims is equal to typical music program at clipping) while the itech current demands from 4 to 2 ohms are almost exactly the same! Plus the itech is supposed to drive a 1 ohm load.

The itech is more efficient with a current draw of around 8 amps or less at 4 or 2 ohms (all while putting out substantially more power) vs. The xti at almost 10 amps at 4 ohms and over 14 amps at 2 ohms , I can buy an xti 4000 for about $625 b stock on eBay and the itech 4000 for about $1500 also b stock on ebay with an extended 3+3 year warranty for an additional 3 years in coverage, ( am I trying to convince you guys or myself right now?) now the kicker is I can run a small monitor amp + the itech and all else from a single 20amp circuit

Finally to the questions, I have read that some of you guys are or have ran these amps and would like to ask would I be asking to much from this single amp? And is a 2.5 ohm load pushing it?

Got the money for the itech? do it! its like, 2.5 times more expensive. lol.

Having used both I will state for the record unequivocally:
If you can afford the itechs, get the itechs.

The XTi is a pro-sumer grade amplifier.
The I-Tech is a full tour-grade amplifier.

You get what you pay for. The built-in thermal & peak limiting in the DSP on the I-Techs is reason enough.

Actually, you can get an for ITech 4000 on ebay for $1299 less 8% bing cashback and 2% ebay bucks using "buy it now" for a total of $1,169.10. shipped free.

The same 10% discount combo and free shipping also goes for XTI series amps.

+1 on the DSP/limiters on the ITech...way better.

Who is it here that says "buy once, cry once" it sounds like good advice whoever that is!

the $1299 ones are giged amps are they not, could it be years old?

can anybody talk about the 2.5 ohm load being good with the itech?, I mean from experiance.

I would like to hear some real feedback on this as well.

To expand on this a bit, also adding the point you could wire subs in series/parallel and not lower the impedance/ohms down so far.

Due to the high output voltage of this amp, what would be the max subs (assuming 8 ohm 3012lf or 3015lf drivers) could one safely run (series/parallel wired) on one channel?

NICE! did not see that one.

FYI Bing cashback program ends on July 30th.

Never used it but went to the site and registered, I have to say I have been seeing these bing cashback offers poping up and thought "there must be a catch" so I never looked at them.

Does'nt seem to be one other than a little more spam "get tons anyway" and the 60 day wait period to claim the money.

Its a rebate.

Don't see the bing cash back coin on this one, guess it is not eligible?

login to bing.com and signup for cashback

go to the search box and type itech 4000

then it will take you to ebay and you will see it next to items that are marked "buy it now" in your search

When you are in ebay you can signup for 2% ebay bux bringing the total discount to 10%
