MB Quart PVL 216 with Sound Dampener

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.

Clean, refreshing sound, great value.

I have these installed in the doors of my 2000 cavalier Z24 winter beater, upgrading from FSB-216 separates.

Previously performed custom work to install 6.5" woofers, and these dropped right into the previous cutouts with no modifications or clearance issues. After a few days of varied listening positions, the tweeters were installed in pods at top of doors angled slightly upwards and partially on-axis. These tweeters are not as directional as I was expecting and provided a spacious stage and decent imaging with practically all of my installation positions. I still added a minor time alignment correction from my headunit to balance the image. Doors are vibration damped with dynamat, and speakers are driven with 120 rms per channel. Head unit is a Kenwood X995. I listen to all types of music, including top 40, folk and rock.

Compared to the FSB 216 set that these replaced there is a significant improvement in the smoothness and response of the high frequencies. I have the tweeters set at the -6db setting, and while not perfect, they are quite smooth and bright without any real harshness, with a sound that is typical of fabric domes. Midbass is quite good for a 6.5" driver, but don't expect these to replace 8" or larger bass drivers. I did try running them full range to get a feeling of their low frequency extension, and I ended up running them with a 12 db/oct HPF at 60 hz. which still lets them provide impact without the stress of any real bass duty.

At first look, the speakers appear expensive with engineered plastic baskets and large crossover boxes. A more detailed inspection reveals the construction tolerances on the woofer voice coils, the inexpensive components inside the crossovers, and the extremely thin 22 gauge wiring used to connect the tweeters. Also, while the woofer baskets look neat, they are not comparable to cast baskets and if your woofer mounting location is anything but flat they will deform to your mounting location - probably with negative effects. These are not $500 components, but they are definitely a step up from the lower, FSB 216 end of the spectrum.

Installation wise, the woofers top-mount 2.5" depth may require spacers for most door installs to clear the window, however this is typical in my experience. The tweeters are quite large in diameter, but shallow if a flush mount is preferred. The tweeters can also be angle mounted or mounted co-axially with the woofer, all with the included hardware.

I have spent quite a few hours listening to these components and have found them to really come alive at SPL's around 100 dB in car. At low volumes, the tweeters are overly efficient and midbass is lacking. At high levels, the tweeters start to exhibit breakup, but they will play cleanly to about 110dB with no listening fatigue or added discolouration to the music. With much of the World listening to compressed media files on mobile devices, these speakers, much like all mid to higher end aftermarket speakers driven with decent equipment, will expose the sonic flaws in your *acquired* MP3 collection.

In summary, I am finding real enjoyment listening to the favorites from my CD collection again on these speakers, and I don't think anyone would be disappointed with these units, especially considering the price.

Clarity at it's best

I recommend these component speakers if your looking for a mid price range setup that has great sound.

I upgraded from the FSB 216 and you can definitely hear the difference between both sets. I installed the rear set first and listened to them to compare the fronts that were FSB216's.

The highs from the tweeters were first set to -3 dB and were sounding somewhat weak; then I set them at 0db and the change made quite a difference and I tried these settings over various styles of music. I could hear the PVl's over the FSB's with the vocal range and highs being more to my liking. The bass was sufficient with clear thuds, but that may have to do with the baffles I installed behind them.

I have these hooked up to the new Crunch 1000.5 and have a Boston 10" sub in the trunk.
I have a AudioControl LCQ1 that has an separate 8 band equalizer for front, rear and sub. With these options I am able to fine tune the system to my liking and am very happy with my purchase of the MB Quarts Component setup.

Great Sound

I was having issues with a set of my Bostons Acoustic Pro series and had to ship them out. Ordered a set of these to use in the meantime. They sound so great I haven't bothered to reinstall my Bostons. Great highs, great mids and warm lows. If you are looking for a component system and are on a budget i would highly recommend. Thanks Sonic Electronics I'm a returning customer!

Great but some build issues

Well I haven't finished the restoration of my car yet but I have installed the speakers and run them through my amp. My doors are not forming a "sealed" box yet but I can definitely say these drivers are punchy and deliver clean mids and crisp highs. Bass is lacking but expected without a sealed door. My dislikes are the build quality... I bought 2 pairs of these drivers. When I pulled the first driver from box 1, one of the small pieces of plastic grill fell out. It happened again with a driver in box 2! Its a PITA because I have to glue them in myself. Also, some of the allen-key terminals on the crossover are difficult to turn with one not even tightening right up and becoming useless.
