Hello All,
Right now, I am using an Energy S8.2 sub.  I use a Yahmaha RXV2500 as a preamp to an HK amp.  My Speakers are the Infinity crescendo.  I am looking for a tight, very accuarate, musical sub.  I am not interested something that will shake my house.  Tight and musically accurate is what I am looking for.  Does anyboby have any suggestions?  And Oh yeah.............. money is an object.  Thank you
