MTX 5515-22 55 Series Subwoofer

The MTX Audio 55 Series subwoofers are the perfect solution for improving your car sound quality while taking up little space. Their low profile means they do not need a large enclosure and will still deliver powerful bass. How do they do this? With an improved surround compared to traditional Half-Roll surrounds, expanded surface area and reduced distortion due to progressive suspension controls. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio with their products, and the 55 Series is no exception!

MTX Inverted Apex Surround

The MTX Inverted Apex Surround increases the surface area of the sub to allow for more air movement, accurate bass reproduction and higher SPL. Traditional Half-Roll Surrounds have an inherent wrinkling when reproducing bass due to the physics of its motion, which causes distortion. The Inverted Apex Surround moves symmetrically through both positive and negative cycles which eliminates this type of distortion.



Progressive Suspension Control

Progressive Suspension control the excursion of the subwoofer at high power levels which reduces distortion. Eliminating this 3rd order distortion means you can play your music loud and rely on your subwoofer to take of itself.



Radial Ribbed T-Yoke

Two features really make sure the MTX subwoofers stay cool: the Spider Plateau Venting and the Radial Ribbed T-Yoke. The Spider Plateau Venting is a mechanical cooling process that targets cool air at the voice coil. This means the subwoofer cools itself as it is playing. The Radial Ribbed T-Yoke acts as a heat sink that dissipates heat and decreases distortion.

Belva Subwoofer Boxes with Polyfill and 3/4-inch MDF

Built for Bass

You've got an awesome subwoofer there, pal. But where's it gonna go? You can't just throw that thing in the trunk and call it a day. Don't worry, Belva's got your back. With superior construction, great features and everything you need for bass, you'll be ready to pass up that entry-level box you've been eyeballing.

Belva Subwoofer Boxes are CARB Phase 2 Compliant

You get quality boxes with solid 3/4" MDF because nothing else will do the job right. You want to flex your windshield, not your box's innards. You get polyfill built into the box, making sure your subs perform perfectly. On top of that, you get a box that's CARB Phase 2 Compliant, meaning your box won't emit as much nasty formaldehyde as the competition. Better for your bass and better for you.

Belva MDF 3/4-inch Thickness

Look, nobody buys a subwoofer and says, 'Aw man, I just want a teeny bit of thump.' Naw man, you want something that kicks you in the chest, but you need a box that's gonna put up with it. That's where Belva comes in. While other brands use less-than-optimal 1/2-inch MDF, we've got 3/4-inch MDF to make sure you get all the bass you can handle. Why risk a busted box? Belva's the obvious choice when it comes to giving your sub a good home and giving you the low end you're looking for.

Nice Box

The following review is for MDFS15, which is a part of the bundle you are viewing.

Very well designed Box. The carpet on this box is really nice and the box looks perfect. I have a kicker cvr 15 in this box and it absolutely pounds!! Oh yea and if you have a New body Style(04-08) f-150 it will fit in the space between the passenger seat and the rear seat with the smaller rear seat on the passenger side flipped up and the box will face up.

Couldnt Ask for More!

The following review is for MDFS15, which is a part of the bundle you are viewing.

Purchased this box for my JBL W15GTI MKII. For the amount paid and product received, its a great purchase. Couldn't have built this or have it built locally for even close to the price. Is it as good as a custom ported box? Probably not but that would be subjective but I love the SQ coming from it now. Can't comment on the durability because I've only had the box for about a week but I do not hear any leaks or rattles from the box. Connection pieces are solid. But best part of my experience with this purchase was the customer service given by 'Justin'. Gave me a great deal and got it shipped to my door within the week.... Couldn't ask for more. Would definitely recommend it.

W/ 15" Kicker

The following review is for MDFS15, which is a part of the bundle you are viewing.

This is a great looking box. Well designed and built. The carpeting looks amazing. It's big, but fits perfectly in my '99 Durango. I figured I would have to remove the 3rd seat when I saw it, but there's actually enough space where it isn't even touching the seat or rear door.

Perfect

The following review is for MDFS15, which is a part of the bundle you are viewing.

Fits very nicely into the back of my '90 Jetta. Could even fit two in the trunk if I crammed them together. Carpeting is very nice and so is the construction quality.

Decent Enclosure

The following review is for MDFS15, which is a part of the bundle you are viewing.

The box works great for my new Polk MM 15". It's a little bigger than the recommended 1.5 cubic ft. but it seemed like it would suffocate in a box that small. At the 50 dollar price point you can't hardly build yourself one for that and this one has quality connectors and it's built solid. Definitely recommend to someone looking for a 15" sealed box. And Sonic was great with shipping and customer service as always.
