E8SV | E10SV | E12SV | E15SV

Was a perfect fit in my Grand Marquis to have a small subwoofer and the price is actually good and it seems quality enough for what I'm doing. The sub was finicky to put in but that's not the boxs problem. The main and really only problem I ran into was the included terminals and wire gauge used on the terminal case. Waaay too small for my comfort level on a 500 watt rms subwoofer. So I had to take the terminal case on and solder on larger wires. After that it's functioning as I prefer and is the perfect size for the space as seen in the pictures if I post any.

This is a reallly good box for the price, can't go wrong. As another reviewer said, the description is a little misleading as part of the construction is 3/4" mdf (as advertised) and part is only 1/2" mdf. I sprayed the interior with plastidip to sort of thicken it up and prevent vibration, although I'm not sure if that was necessary, it does seem well built and glued together.Porting frequency seems a tad high (see UPDATE below), maybe 45 or 50hz or even higher? ...but it's easy to lower the porting frequency with a wadded up old tshirt or a pool noodle as another reviewer suggested. In an automotive application it might be low enough, for home theater or dnb or hiphop shows maybe experiment with a pool noodle in the port *grin*.Overall, this is a fantastic box, well built, pretty compact, a real steal for under $80 shipped.~~~Note you will need a drill bit for speaker holes, some screws for mounting, some wire to connect your sub to the terminal.UPDATE: Confirmed the porting frequency is much too high, added it at a show to a KV2 dual 15 (one of the best sub setups) and this was literally canceling out the lowest notes of the KV2. We finally shut off this sub. BUT, that is an easy fix, partially obstruct the port with something like a pool noodle OR if you are near a wall place this sub an inch or way from the wall facing the wall. This will effectively lower the porting frequency and it won't cancel out the 35 hertz notes from your other speakers. Still great for the money!editagain: In my pic I'm using "Allstar - ALL14100 Black 3' Roll Bar Padding" to mostly obstruct the ports and the porting frequency after doing that is about 31 hertz. MMM mmmmmm (I'm guessing it was 45 or 50 hz before that, much much too high)

Bass sound awesome, for this 8" woofer box. Get it. You will love it.

4 stars because a little damage during shipping see pic other than that box seems sturdy and heavy.

I put a more real 10-in award-winning baseball for in this little box and boy the base came to life so clean deep and Rich unbelievable little box for the price

Perfect size box and look i will prefer the carpet was black because my trunk is black but is ok is charcoal gray i still love it i have a kicker compR and fit perfectly fine no modifications needed i recommend it is pretty solid

Using it with a CERWIN-VEGA sub. Even at low volume produce a pleasant sub sound. At high volume it really rumble my room.

The construction seems nice but it's missing the emblem on the front as pictured and it came with damaged corners. I repaired the carpeting but it was disappointing. It performs as expected.
