Of course until we see the exact tests on many amps it is all guesses anyways. The whole point of a theater is to have what one needs for their goals. No reason to come to a clone thread and poop on it.
Reaching a certain dB in room has to do more with the subs and room than amp. How much power are you really using to reach 100 dBs at 10 hz in a room? Every room and subs vary. I guess for us to really test in our rooms is to run say a crown amp on your subs and see what the max is at 10hz. Whether it is THD limited or amp clipping limited. Then run the same test with a Sanway and see if it changes and by how much. One can figure out things for their room and setup. Ok, who wants to start swapping stuff to do this? I guess I can run a EP-4000 for a comparison, etc..
The allusion was of course that there was no or little rolloff (at least none evidence, thus far). I guess I should have been more exacting.
"pooping"? Is that what being saliently critical is called these days? Is this thread simply a praise-party? I thought it was to discuss the amplifier- pro and con. Seems like there is AMPLE evidence for the VERY same reality on other amp threads. And who's "pooping' anyway...as I said, it's a fine option for those who need hyper-power, so long as they're aware of the limitations and other cons. It's an amplifier, not someone's child.
Honestly, I'm not terribly interested in going OT about what's most important in reaching a given SPL in a room...you need all three variables one way or another. This is simply viewing this amp in the same light we do all others...for better and worse.
The clone produces more power than the Crown and other amps...no reasonable or intelligent person would dispute that fact. I'm simply suggesting that the output
difference vs comparably priced amplifiers should be carefully considered, and weighed with all of the other variables.
And I'm glad you brought up "goals" as that's what's really important and kinda why I start to ask folks to REALLY consider the 3-4 decibels. Where are you before
you go up another 3? For many, it's absurd and really out of whack with the balance of the content (see 130+ db bass and 85-100db output elsewhere) , but again, that's up to consumer to decide and no one here is telling them they cannot choose as they see fit.
