If say my amp is a Denon 4311 or an Onkyo 3009 (both 9.2), would I be able to rely on its Audyssey XT32 to fix my sub's low frequency if I use both a sealed and a ported sub? Say I use one output for my ported sub (SVS PC13Ultra) and another output to a sealed sub (SVS SB12NSD)?
If I add another sealed sub on a Y-connector to the current sealed sub making it 2x SVS SB12NSD on one output and place the subs far from each other (beside Left and right front speaker), plus my ported SVS PC13Ultra on the other output of the amp, can the XT32 still handle this?
Would Audyssey XT still be able to handle all the above configurations? Or once you get more than 2 subs, it is a must to go XT32?
