    • Very nice
The media could not be loaded. Good size port, good build quality, lots of polyester filling on the inside. Only complaint about it is they used screw down wire holders and not spring loaded push downs but either way box is nice and sounds good af. Using a SDR 12” in it. Before I used a Jensen 12” from Walmart and it also hit hard af in this box too ... show more

    • This box is made with the best materials
Size: Single 10" Sealed
The box looks good and I can tell it's well made! I will know in a few weeks if I picked the correct box, I'm sure I will be buying more from them

    • Nice heavy solid prefab box with no leaks.
This box has great sound for rock AND rap music, it’s tight enough to feel the kick drum in rock but loud and boomy enough for rap/hip hop. The pre installed polyfill is of good quality and well installed with no gaps. It definitely helps this box sound good! The mdf material used is heavy and solid, screws will not easily strip out like cheap boxes. I used long agressive deck screws after predrilling the holes. My sub is a Pioneer TSW126M (easily the best budget sub out there for all music tastes.) I used Amazonbasics 14 gauge wire from the terminal to the sub. I would recommend soldering to the terminal for bigger subs. My JVC head unit has the sub low pass frequency at 60hz with a slope of 24db. My speaker high pass is at 80 with the default 12db slope. I’m running the sub off a Class D Pioneer amp. Alpine 4 channel A/B for my door speakers. Good luck with your budget builds! This box is worth every penny! ... show more

    • Good quality, small opening.
Size: Single 10" Sealed
I am using a parts express UltiMax 2 sub in this box. I did have to use a router with a 1/4in bit for my 10in subwoofer to fit. Other than the opening being on the small side, the construction is great. The terminals are solid and sealed. I added a little extra pollyfill as the enclosure volume is slightly undersized for my subwoofer (I planned for this when i ordered). Great for the price. ... show more

    • GREAT QUALITY BOX AT A LOW PRICE!
Size: Dual 12" Sealed
I purchased the dual 12" sealed enclosure for my daughters Jeep Wrangler and installed 2 Rockford Fosgate P3 subwoofers in it. Powered by a Punch 1000x1d amp it sounded phenomenal! I was very surprised to see how well it was constructed. Built with 3/4 inch MDF all the way round, and lined with polyfilm. The carpet was nice and tight and seemed high quality. I use to build custom subwoofer boxes when I was a teen and have even been to some of the competitions in the IASCA circuit. This box is no joke, and if you can't build your own then I recommend this box, especially for the great price! ... show more

    • This box should cost more! It's truly exactly what I wanted and needed
Size: Dual 12" Sealed
I have two JL Audio 12W6 v3 subs. I had them in a ported box, but due to the variety of the music I listen to, the ported box was way too "boomy." It hit hard, but since no one masters tracks at similar balance and volumes, some tracks would sound really great, then another would have so much base, I was constantly adjusting the bass control on my Fosgate T1500.1. I mean the boom was strong enough to break my rear view mirror from the windshield three times, with the last time taking the glass with it. Enter the idea of a sealed box. While I get less vehicles shaking bass, I get considerably clearer thumps from the kick drums in metal, to a great clear boom from rap and hip hop. This box is very well constructed, the perfect size, packages really well, and arrived a week and a half earlier than projected. I got it in three days rather than the two weeks quoted. IF you want or need a nice compact box, and your subs need about 1.1 cubic feet of air space per sub, this is the box you need. With the displacement of the sub considered of course. Keep in mind, you do lose about 10Hz in the low end going to a sealed box, but boy it's made a world of a difference. ... show more

    • Durable and quality!
Size: Single 12" Vented (Gray)
I've spent 7 months with this and let me just say my 1200W Alpine Type-R is still a rock solid combo. This port completely rattles my back windshield and dash mirror when the bass hits. Literally cannot see when it happens. I had it in a cheaper sealed enclosure before, and this makes a HUGE difference. What I like: - Made from MDF - Bass is.. just absolutely phenomenal - Solid, heavy as hell once a sub is in. Get some velcro hooks and put it on the bottom it holds no problem. - Easy threading into the MDF and a solid hold - Price is pretty cheap for a nice enclosure like this What I didn't like: - I think it was the glue + fresh MDF because this thing has the weirdest scent. It aired out after 2 months of blasting air out of it but pheeew especially on a hot summer day like when I first received it. I would hop in my VW GTI and get burned while 'smelling' hot glue and MDF. - Had quite a bit of foam padding inside, had to cut some out to wire my subwoofer at a different ohm. Things to take away: BUY BUY BUY! It's a solid steal if you're like me and spent too much on the subwoofer and are kicking ourselves because of it. The pros outweigh the cons in my opinion. ... show more
