Subwoofer for classical music listener

Al:  I notice the SVS-SB 2000 is only $200 more.  My room is about 575sq ft.
the 1000 is recommended for small to medium sized rooms.  The 2000 is ported.
Is the 2000 a match for my amp as well as the 1000?
Sorry to keep bothering you!

Rvpiano, the SB-2000 is described as having the same 47K line-level input impedance as the SB-1000, so using the PV11 to drive both the SB-2000 and your amps should be fine.

Tim (Mr_m), first I'm pretty certain that the DC offset issue which Rvpiano experienced using his amps with the 2Wq doesn't apply in your situation.  I believe that issue applies mainly (or perhaps entirely) to certain older designs utilizing ICEPower modules, while the Pharaoh is Hypex-based.  Also, I don't see anything in the manual for the Pharaoh cautioning against connecting a sub or any other active device to its outputs.

As far as the issue you described is concerned, I'm understanding that the symptom just occurs on the output of the sub, and not on the outputs of the main speakers.  And I assume it occurs on musical passages for which imaging is centered between the speakers when the balance control is set normally. If so it would certainly seem to point to an imbalance between channels in the input circuit of the sub, which would be surprising.  And if so it may be worth contacting RV (the sub designer, not the OP :-)) and seeing if he can shed any light on it.  Beyond that I have no particular thoughts about the issue.

I called SVS an they assured me the SB-2000 has the same line level input (47K) as the 1000, so I ordered it.
Thanks everyone for your help (especially Al) in choosing a subwoofer.
I hope this one works out.

Rvpiano, one further thought. I recall reading several years ago that at some time in the past DC blocking devices were marketed specifically for the purpose of connecting powered subs to amps utilizing the ICEPower-based class D modules that had the substantial DC offsets. Although I suspect such devices are no longer available new, it may be possible to find some used ones, which would presumably make it possible to use the 2Wq you already have.

Edit:  This was written before seeing your post just above.

PPS: Rvpiano, ignore my last post. In addition to the fact that you’ve already ordered another sub, I’m uncertain as to whether the DC blocking devices I referred to would be suitable for use when monoblock amplifiers are used in conjunction with just one sub, given that the sub probably connects its negative input terminals for the two channels directly together.
