JL Audio of Florida builds UBER serious subwoofers. For two channel listening, JL emphatically encourages a PAIR of subwoofers to balance your room with bass. How about a pair of E-112s?!

E-112 $2500 Each (16.23h, 15.5w, 18.39d, 74 lbs, 1500w amp)

E-112 has a driver like you’ve never seen before. Note the double spider design.
Please also note the front metal baffle the driver is adhered to.
The driver is a football field deep and needs a special support mechanism in the rear of the enclosure.
Not only is it more massive than anything else out there- it sounds deeper/tighter.
E-112, is not your garden variety woofer, screwed into a flimsy box with a plate amp off the shelf.
E-112 also features bass management if you can employ it. You can run your preamp IN- and then run OUT to your power amp. NOW, your wing speakers (and amp driving them) won’t be encumbered trying to play deep bass- which they can’t do as well as E-112 anyway.

We invite you to visit to hear A PAIR of E-112s with Maggies, among other speakers.

With bass this substantial, you might re-think your system design. If you KNOW you’re going to let a pair of E-112s handle the bass… your wing speakers don’t have to go so terribly low after all.

You might just love a pair of reasonably priced Maggies or Klipsches- because you don’t care how DEEP they’ll go. You’re just looking for 60Hz on up magic!
