Since this forum is largely concerned with domestic audio I think it may be interesting to post measurements of a more modestly powered (2x350 watt) Yamaha P3500s: https://www.homecinema-fr.com/forum...mpli-yamaha-p3500s-mise-a-jour-t30056383.html In practice, the fan of this amplifier never came on during the tests. Encouraged by these results I bought a 300 euro 2x250 watt Yamaha P2500s for my son, and here too, in home use the fan never kicks in. Do I need to say that it sounds great (i.e. like any other decent amp)?
I have the P7000s pulling a pair of Infinity Kappa 8.2i's. No noise or nothing. Just an amplified signal.

I plan to use XTi 4002 to power 2x 18" subs at 4 ohm each (1 per channel). Would it be a good match (for HT)?

Those subs can go to single digits so I guess in this regard it is not but at the same time I should be pretty ok with 4002 being able to do something like 7hz at -1.5db.

What I don't understand is how much power it can deliver at 20hz or lower hz at 4ohm load.

Do I read the review correctly that at 1% THD it can deliver 900W into 4 ohm but at 20hz it drops to 647W and how steeply it drops going lower than 20hz?

Let me know guys what to make out of it.

How bridging it would affect those numbers?

I am also considering XLi3500 / 2500 either bridged or dual channel.

Hopefully someone will offer them for testing. I considered buying one myself for testing but even dealer cost is way up there.
FWIW I have via PM. A long list of Pro amps. The older iTech8k is one of them.

We need to clone Amir so we can get more throughput ;)

Note: Amir has not been slacking, the sheer number of reviews going up every week is proof. Too much to test, so little time...

All will work. Imagine strapping one of these on back of self powered sub.

Hi

Hoping for some input on an issue. I know a guy with this amplifier that won't output sound. It turns on and the signal leds react to input signal. Could this be the ribbon cable to the main board from the control panel as some of the other Crowns suffer from? He says he hears relay click..

Troubleshooting over the internet is actually very difficult. We have a few guys on here who have many years repairing audio gear and if they don't respond it means they didn't see your post or it would need to be looked at in person. Try seeing if Crown has any authorized repair centers near you, if not then just go to any audio repair place, they are not that hard to fix. As usual though cost of repair is an issue vs buying a replacement. They were having a 5 year warranty but I don't know its still on. 5 years is very good!
