Subwoofer for classical music listener

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.

I am using two JL Audio F110v2 with a JL Audio CR-1 crossover.  Very surprised no one has mentioned this.  This is an incredibly seamless system once calibrated.  The calibration does take time but the crossover allows you to do this with precision.  My speakers alone have nice bass response but once i added the subs with the crossover it took it to a new level.  Highly recommended 

Al:  I'm just as happy to have a new sub instead of the very well worn used one, of which I'm sure I would be the third owner.

I just got back from my first day at LA Audio Show. Some impressive, some depressing demos we got here. Could not help comparing what I hear to what I already have at home (see my profile system). Not too many demos have a sub, but the one with two huge ones (Audeze, going mainstream) playing Dead Can Dance (in constant rotation thru SACDs and LPs at yours truly) was not opening my eyes/ears into another dimension. Maybe because it was 16/44 streaming, I will never know...
My point is: no one so far responded positively to my old Q of reproducing the sound of a Cathedral Organ at home. Its a good reference point, easily available to anyone. If you cannot bring pipe organ into your living room, then all the heat of some previous posts is moot, at least for me. 
I tried and failed! Should I buy a second sub, or two bigger ones, or delve into DSP room correction???
Those in the know, please help!
