i would recommend this product to some one who has knowledge of sound systems. It was difficult to tune(drilling holes) but if your looking for something to seal the rear end of your speakers this product is for you

They are cheap buy so if you don't end up liking the sound quality you can always throw them out. I recommend buying these if you want to keep dust off the magnet, backing and wiring.

Review written by Kevin from La Crescenta, CA
These bass boomers were the perfect addition to brand new blaupunkt 6x9's in my civic. They fit perfectly in the rear deck holes of the civic and the blaupunkts fit perfectly in that. The one thing i really liked about these bass boomers is that u can fine tune your system. Those holes at the bottom are awesome to find the right balance of air to the speaker. all i did was cut them one by one until i got the perfect sound out of my 6x9's. They really tightened up the bass.
