BB-T Bass Blocks Designed to Protect Car Audio Tweeters, Eliminate Frequencies 0-5.6kHz at 4Ohms, Pair

I upgraded my dash tweeters with new Hertz DCX 87.3 tweeters. My factory uconnect stereo was making them produce a ton of bass. One of the speakers had a slight buzz-like distortion during spoken podcasts and I was worried that new tweeter was already blown. After a bit of research I found it was likely due to the frequencies the speaker was receiving or possibly a bad connection somewhere. I pulled the speakers out, then soldered the bass blocker to the positive side on my aftermarket speaker adapter. Heat shrink around the solder joint and then soldered the +/- 1 counter wires directly to the harness adapter. This was merely to get rid of the possibility of there being a connection/connector issue. I reinstalled, then tested them. All the bass and distortion was completely gone. My new Hertz DCX 87.3 tweeters are loud and clear now during spoken podcasts. Next project is door speakers.

They work great. I updated the speakers and factory radio in my truck. The dash 3.5’s sounded terrible and were distorted with bass. These took about 10/15 minutes to wire in and eliminate all bass from my dash speakers. It’s sounds so much better

Un costo extremadamente excesivo para no ser más que un capacitor que no cuesta más de 1 dólar.

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!

Great
