Subwoofer hunt


Hi folks. In the market again looking for a subwoofer...this is to complement my Focal Electra 1008Be with Hegel H160 setup. I was looking at JL E110 sub. Anything else I should be looking at? Also do the amps of these subs blow up frequently?

I recently put together a system for my kitchen and decided on a Hsu VTF-1 MK II to go with a Cambridge cxa80, Schitt Gungnir multibit and Scansonic MB-1s. Because of not being able to do a straightforward placement of all components flexibility was going to be key. The options on the Hsu made fairly quick work without a lot of sub crawling and if it weren't a big black cube would be as invisible as its well blended sound. I'm impressed as hell for the $450 it cost. 
@hifiman5 thanks for the detailed post hifiman5. one quick question, wouldnt the current on the speakers drop if you connect subs to them in parallel? because current would decrease for parallely connected components right?
The Q control is very useful, but -1 for using amplifier outs. Gives you very little flexibility. I'd rather have control over the high pass and low pass. 

The real issue subs face isn't the electronics or the speakers, its' the room. Using a miniDSP and proper room treatment this is straight forward. 

Best,

Erik 
@jldouglas : thanks jldouglas. You think I should give E110's another chance and listen to them with my setup? I was leaning towards the Rythmik F12SE.
Imo a decent sub in a treated room will perform better then a pricey one in a untreated room . Vandy subs are great but the setup can get costly . Its all in your court buddy
