RECOILBB-65 Bass Blocks Designed to Protect Car Audio 6.5 Inch Speakers, Eliminate Frequencies 0-600Hz at 4Ohms, Pair

I bought a pair of infinity 3.5 to replace the OEM ones on my Ford Explorer, I used the infinity bass blockers that came with the speakers and the speakers ended up with that annoying crackling sound, I returned them and spoke to a friend who is a professional high end audio installer and he said to purchase these bass blockers as they are excellent.Right away the feel of these were far superior to the ones that came with the infinity. Easier to install as the ones that came with the infinity were a hard Coper and these were more bendable to make the install easier.Once I installed them, I immediately put some house music on, and played it loud, three weeks later and these were an amazing choice. No blow outs, no crackling, just amazing sound.

Used this product on my Kicker 3.5” speakers to remove the bass. Now speakers sound nice and crisp without any distortion. Originally purchased PAC brand and they never worked out of the box so thought I’d give these a try . Excellent product so don’t hesitate to buy

Nice product

I don't have a wild stereo system nor do I know much about them but noticed my 6.5" speakers were getting more bass sent to them than I wanted no matter how much I used the deck to adjust the EQ. Since I don't have a stand-alone EQ I decided to go this route knowing it was inexpensive. It seemed to have removed enough bass that my 6.5" speakers are alot more clear sounding that before and the bass is being felt thru the subs like it should. Although the 6.5" are not super crisp, they did the job I was looking for. Again, this worked for my application. Not a stereo system genius but this got the job done inexpensively.

Really nothing to dislike but I like the product enough works great cuz it's job and very cheap housing anybody out there looking for baseball offers don't spend all kinds of money these work just fine
