Subwoofer for classical music listener

Yogiboy, thanks for pointing it out and thank you for the encouragement too!

I'm glad your encouraged  I just want you to realize 
when you hook up
your amps low input imp and the subs in RCA parallel  w your tube Pre amp it will see a very low imp load 
 Lifeless may be the result

OP--See Almarg's note above.  I think you are going to be fine with the impedance matching, as long as your pre doesn't spike too much in the low frequency.  You have a very solid trial period with SVS.  Let your ears judge.  Sounds like you know what you are looking/hearing for, and, if you don't find it, you know what to do.

Your biggest hurdle is probably going to be placement/integration, especially if you need a large "sweet" spot.

Hi JohnnyR,

As I mentioned earlier in the thread the line-level input impedance of the SVS SB-2000 is 47K, which is much higher than the line-level input impedance of many and probably most other powered subs. In combination with the 22K input impedance of the OP's amps that will result in a 15K load being presented to the preamp, significantly higher than the 10K minimum that is recommended by Conrad Johnson for the particular preamp.

Regards,
-- Al
 

I got it Al but will still wage the 15 K combine will not be optimized.
Three positive things could result if he was able to High Pass with a non
Ice design move to a100 k input imp amp and go at it x 2 at speaker level.
 its sad because its what he was really looking for in the first place.
