MB Quart DS Inch Shallow Space Saving Slim Subwoofer Car Speakers with Dual Voice Coil for Vehicle Sounds Audio Systems, Black

Bought this cause I needed a shallow mount subwoofer to fit in a shallow box in a truck. Sub seems well made has good quality speaker push terminals. Sounds good for a shallow mount sub. Only 200 watts RMS but that's all I needed. Good quality subwoofer.

I love these MB Quart subwoofers; they have deep and very tight bass.

For the price I doubt you can even match this sub. It’s not a sound quality sub. I’d used used JL audio, Sony, MTX, Polk, Audiobahn, and now MB Quart which used to be amazing in the 90’s. This sub isn’t “musical” not very tight, but that can definitely be at least partially my factory amp (2019 Golf R) causing that. With the recommended .65 cu ft box the sub favors 60-80Hz and basically falls on its face below 50Hz. I put it in a box I have that’s .81 cu ft and it sounds considerably better, peaking at around 35Hz. I’m out of wood, but I’d imagine .75 cu ft with some polyfill would be great. It fits in a 4” tall box built from 3/4” MDF. It’s the only 10” subwoofer that I could find that was less than 3” mounting depth. If you have a Golf R without a spare tire do yourself a huge favor and get one of these. Even though it’s dual 4 ohm coils rather than 2 ohm coils the amp runs it great. I’ve lost zero usable space and have bass down to about 25hz now.

I have this running in a small box for a 2012 Chevrolet Silverado Extended Cab truck. I used a generous amount of poly-fil and the box is tiny as it is (appx 1.6cft). I have an MB Quart mono Class A/B amplifier rated at 400W max running this subwoofer at 2ohms. It has a remarkably deep sound considering that it is so shallow. I would like to be clear, this is NOT a replacement for a JL W7 but in this group of woofers at ANY price point this thing is worth every penny. If it lasts several months it would be worth purchasing another should it fail. I cannot adequately express how pleasantly surprised I have been since the installation of this speaker. I paid for it with my money, no promotion or gift and I will gladly do so again should that become necessary.

I mounted a custom depth sealed box in a soffit rafter bay and have had this 10" MB Quart exposed to the exterior (albeit sheltered overhang) for over 6 years. I just pulled it off to prep for painting and it is still like new. Love MB Quart quality. Can't wait to get it back in for the patio sound system.

I could not be happier with this woofer. I put it into a 1 cubic foot box and it sounds great. I am going to add a bunch of poly fil and a couple of wood blocks to reduce the cu ft volume down to about .7-.8 cu ft. This is merely personal choices. Perfectly deep enough. Amole boom for the buck. Has a MUCH DEEPER bass response than I could’ve ever imagined out of a 10” woofer. Much less a SHALLOW 10” woofer.

Don't let the low price fool you. This sub may be made in C***a but the German brand name is definitely not an off-brand after-thought. They are no booming window shakers and, in spite of their low shallow mount box requirement, they do "speak" with authority when paired with the right amp. My only minor regret was not choosing the 12", instead of the 10", version but space in my small car was of high priority so I'm quite happy.

Very cheaply made installed yesterday today the coil burnt, gains set very low as the speaker are new and haven't even been broken in yet , do not recommend and I really had high hopes for this speaker total let down
