    • Perfect Little Bass Blockers for 3.5" Dash Speakers
Size: Protect 3.5" Speaker
I installed these RECOIL BB-35 bass blockers inline on my new Kicker 3.5" speakers, and they do exactly what I needed them to do. In my setup, the 3.5" dash speakers are installed in parallel with 6.5" Kickers on the same channel of the amp. These bass blockers help keep the low-end bass out of the smaller dash speakers, which lets the 6.5" speakers hit a little harder in the mid-bass while the 3.5" speakers handle the cleaner highs like they should. The result is a better-balanced sound with less distortion from the dash speakers, especially when turning the volume up. They are well made, compact, and easy to install. The wiring was straightforward, and they were small enough to tuck away in my 2023 Jeep JL dash without making the install messy. For the price, these are hard to beat. Great product at a great price, and they worked exactly as expected. ... show more

    • Great value for cleaner tweeter performance
Size: Protect Tweeter
These helped clean up my sound tremendously. Beige installing them on my tweeters, I would get distortions at moderate volume levels due to lower frequency notes (bass) -- depending on the song. I would have to reduce the bass input and others on my equalizer to clean up the distortion and would not get the sound I really wanted. Now I can get much better performance from my tweeters at any volume level. Great value Highly recommend. ... show more

    • Great to prevent blowing out speakers
Size: Protect 6.5" Speaker
Essential add when powering up your system so you don't blow out your speakers. Easy to install, just splice it into the positive wire. It blocks the low level bass signals from playing through the speaker, letting it exclusively play the mid and high level sounds. With that said, you probably only want to use these in combination with a separate subwoofer so you can still have some bass in your system. ... show more

    • MUST buy for clean, distortion free 3.5” upgrades!
Size: Protect 3.5" Speaker
So…I upgraded to new JBL Club 3.5” dash speakers in my OEM 2018 Chrysler 300 stereo. Chrysler’s built in EQ settings and crossovers on the UConnect basically prevent the volume from getting loud to protect their cheap speakers (mine is a non-amplified system). If you have a newer model 300, you know that the overall factory soundstage is pretty good, it just lacks those crisp highs and volume to really jam out. If you do upgrade to the JBL Club 3.5” speakers, I would HIGHLY suggest that you order these Recoil BB-35 Bass Blockers to install on the positive speaker wire of the speakers. The signal coming from the factory head unit to the dash speakers is a full range signal (highs, mids, and lows). The JBL’s come with a resistor installed that run to the tweeter to protect it from the lower frequencies, but nothing to filter the signal to the actual 3.5”. Initially I had to turn down the bass on my EQ so low to make the new JBL’s sound clean, and distortion free, that I lost that mid-bass that I enjoyed so much from the 6x9’s in my front doors and rear deck. The Recoil BB-35 bass blockers filtered all of those unwanted signals from playing through my new JBL 3.5” dash speakers so that I could turn up the low frequencies on the EQ giving me the upgraded soundstage and louder volume I was looking for. I couldn’t be happier from such an easy and cheap upgrade to my OEM system! ... show more
