Musical subwoofer under $2000

"@kennyc  Usually "musical" means enjoying the music as a whole but can also be at the expense of detail and accuracy. What you are looking for is an "articulate" subwoofer where the bottom notes sound like real instruments and not a boomy mess."

Kennyc,  Absolutly. My description completely overlooked the mentioning of articulation in lower frequency presentation in my question to the OP's meaning of 'musical'. Thank you for making that point. 

I was attempting to bring to the OP's attention that his choice is a -6dB bass speaker that simply doesn't go that low with any authority and whether that was a priority. 

@kennyc  (Just found out how to include replies to individuals!) Articulate is what I want and getting real sound of the instrument (cello, double bass etc.) I'm leaning heavily now to ordering a single Rythmik E15HP2 to start and then going from there. I must admit the app capabilities of both Arendal and SVS appeal too, but with SVS I cannot get a white finish in the model I'd go for and I think the 15" woofer size of the Rythmik would move more air in my room. 

I think you’re making a mistake.  I’d get an F12G and then add another one when you can.  But that’s me. 

@fred60 ,

"I think you are right not to spend too much, as Class D amps (I think all subs use Class D) can’t be repaired once they fail. I spent about $2,500 on a Paradigm sub for my home theatre setup and it failed after about a decade of use. It’s why I’d never buy active speakers. Who wants to buy a pair of speakers that will only last a decade? JMHO."

I sent my JL F113 amp into JL to get fixed. It's a flat $450 charge and they put a bunch of new caps in from the V.2 line, replace anything broken and replace anything that is known to be problematic or doesn't measure out. I didn't think that was too bad a deal. If you send the entire sub in they will even replace or re cone the woofer if there is any degradation. Super responsive emails and really great to work with company IMO. I could not believe when I looked up the F113 current line and they are 6k! At that price I'd say they are probably overpriced! I think I paid like $3,500 12ish years ago. Guess my point is that class D can be repaired like any other amp. 

@mofojo That's great to hear.  Happy to hear that as an owner of two JL Audio subs.  Paradigm was not at all like that.  They quoted me $1,700 to "fix" my dead sub that cost $2,500.  I'd of course rather spend the $1,700 on a new sub.

My point was that unless the manufacturer is willing to repair the sub for a reasonable price, taking it to a certified audio repair facility-- they will tell you that they can't repair it.  

JL Audio is a good exception to that.  Good to know, thanks.
