Subwoofer for classical music listener


This is my second post on the subject of subwoofers.
My first post wasn't specific enough.
I listen to classical music 90% of the time.
Are there any classical music listeners out there who have subwoofers?
if there are, could you let me know what you have?
i don't imagine I would need quite as powerful or expensive a sub as those who mainly listen to other types of music, but I may be wrong.

I added an 18" Velodyne to our system (we too listen to 90% classical) and set it to a relative low level. Even though it is off to the side, the deep bass still appears to come from the center between our main full-range speakers. Bought it on Audiogon for $1250 and drove two hours to meet the seller half-way. It has proven to be a great investment.
I listen to Classical 100% on my main system and love my HSU sub. It's powered and meshes very well with my AudioPhysics Tempos. I think it was about $500.
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.
