Customer Ratings & Reviews

excellent speakers

MB Quart is known for having over-powering highs...

This is not the case with these speakers. I listen to country, pop and rock and the sound these crank out is smooth, seamless and clear.

I like to crank up my music and these deliver a nice rear fill sound for my car.

I highly recommend them over the other leading brands.

great value

not the greatest, by far not the worst... sounds good with some power behind them...

Intense highs

These speakers are extremely clear, especially in the high frequencies. The titanium tweeters create piercing highs which for my taste were a little too much. I think this is a great value for the right listener.

excellent sound for the value

i couldnt be more please with the value vs sound quality. I have had more expensive speakers and they do sound better, but for this value they are quality sound

Great value

Cant beat the quality for the price? Great bass and mids

Bang for your buck

Simple Upgrade for stock systems but I paired it with an alpine power pack and it sounds excellent!

Mb quart has lost their quality over the last 10 years but the price is good and they're acceptable for sound reproduction.

good product

Really stops the rattling that comes from having the punch from the kiker speakers i have installed in the doors of my car.

Easy to use and apply

I used this product in my rear component speakers (Alpines) for the mid-range woofers in the doors to shield against vibration and they do a good job and the speakers sound great for it!

Cache CSM

These came in a package deal from Sonic
with JBL GTO series speakers one of the decisions why I bought the GTO speakers, easy to use. Currently installing the sound system but having used similar products before these will make a good speaker sound better.

Great product

Worked good, stopped the rattling. Deeper bass.

good stuff!

I bought this in a combo package that Sonic put together with a set of hifonics components, the zxi65c. i liked it, i havent heard any rattling from my speakers. works well, i recommend it.

Sounds Great!

I installed the Dead Shield Sound Dampening Material under all 4 of the speakers I replaced in my truck and the stereo system sounds great, better than I expected.

Nice speakers

Speakers are quality made and the design is solid. Glad I bought them, 2 sets. Installed speakers in my daughter's car, they sound awesome. Thanks guys

Sound with Value - Go for It

Purchased a pair MB Quart of 6.5" and 6x9 as other aftermarket speakers I had bought didn't sound as I wanted them to. These speakers made a significant difference, the sound is rich and full and there's improvement on the sound of the bass. And I'm just using the power from the radio so I'm certain that they'll sound much better when I amplify them. Overall a good purchase.
