  1. Insane Subwoofer

    Posted by Jacob on 26th Jan 2017

    This sub is extremely well built. I have 1 in an 8.47cuft box running off a t2500 and omg it's truly insane. The output is ridiculous for only 1 sub. SSA did an amazing job designing it. I'd highly recommend the Evil to anyone looking for the most output for a decent price.

  2. Best sub I've owned

    Monster I should have got two instead of one maybe soon. I'll be getting another

  3. Bad ass sub!

    All I can say is it looks like a beast! Very well built. May get two more.

    SSA FTW superior clarity Lows all wrapped up in one I have two of these Evils on a Sundown SCV 6000 at .5 ohm in a 2010 Ford Mustang walled off in a 4th order nicknamed the MustBang with McLaren highs you couldn't ask for a better combination

  6. EVIL as a Mf

    Posted by Big Mike on 7th Jun 2013

    Ok so I finally got the evils installed yesterday, and I was worried that they may not sound to good.So I asked my installer when I handed them over to him if he knew how they might be. His reply was they should sound good. Well 3 hours later he called me back and left a voicemail"yeah umm mike these things are umm hitting like a muthaf@$#..I only got it a quarter way up and these things are hammering.."..lmao...smh...I gotta say ty to SSA for making good quality speakers...im using a bc5500 at .5 ohms in a design box... smh

  7. 2- 18 inch EVILS

    Posted by Chris Lowther on 4th Apr 2013

    Bought 2 of these suckers and have them on a 10k in a 4th order and I have ZERO complaints, absolutely love them! Mark and Aaron have been great to work with while ordering and recommend these or any SSA product. If ya don't wanna take my word for it I'm in Georgia and would be happy to give anyone a demo! :)

  8. EXTREMELY satisfied with this Evil!!

    Posted by Sencheezy on 19th Feb 2013

    I am EXTREMELY satisfied with this Evil!! It is truely an amazing subwoofer. Its just a completely different sound that I am not use to. Not for my own vehicle and nor any others beside Swift's F-250. The clarity and bass reproduction is simply phanomenal. I really can't say enough good things about it, and if you are on the bridge about getting one, DO IT! There is just simply no note that this subwoofer doesn't pick up. For example, in just ONE song, you can literally be slaped in the face by the higher notes, and then without a notice later, have your ass shaking out of the seat from the low notes. I was kind of weary about throwing 128cuin of port to just one subwoofer, but man, what a outcome this has become. To do nearly a 150 OUT OF THE BOX in a completely daily box, is just has been fluttered with butterflies. I get blurry vision, I have so much flex now that needs to be addressed, and I have electrical back bone thats needs to be looked at as well.

Product Description

When your sub bass goal is nothing but supreme, unrestrained performance without compromise, the choice is the SSA Evil.  The capabilities of the SSA Evil put it in very exclusive company at the zenith of the marketplace.  This is where you look first for the ultimate 'ground pounder' that will not miss or muddy a note.  Crisp and clean across the entire frequency range for those demanding outstanding linear performance thanks to an FEA optimized motor.

Employing a massive triple stack motor, five sandwiched 10" progressive Nomex spiders, an anodized vented Aluminum former, a huge 4-layer 4" flat wound Aluminum coil and a towering 'Venturi' solid pole, the SSA Evil has the muscle to handle almost anything you can throw at it.

The SSA Evil is also a top pick for extreme level SPL and bass-boxing competitors alike, while still having the composure for the elite home audio projects.  A versatile monster that will meet the most critical low frequency demands while achieving extreme output levels when called upon.  Sonic performance so vicious, it had to be deemed Evil.
