## Questions & Answers

**Q: Will these work on 4 inch speakers?**
A: Yes, these bass blockers can be used to protect your 4" speakers as well. The BB-35 blocks frequency under 2800Hz for 4Ohm speaker, The BB-4 blocks frequency under 1200Hz for 4Ohm speaker.

**Q: How muh does it block on 1 ohm ?**
A: Following quick and dirty math, the frequency doubles at 2 ohm (0-600 hz).  That would make 1 ohm frequency blocking 0-1200 hz.

**Q: Will these fit in the upper dash of a Wrangler JL for the tweeters?**
A: Yes, these bass blockers are super small and compact, they should fit into the upper dash of Wrangler.

**Q: I have 4 ohms tweeters, how will it sound with these 4 ohms blockers?**
A: All it will do is drop off the lower frequencies (which tweeters can't play anyway). Your highs will play through perfectly.

### ⭐⭐⭐⭐⭐ Good inline bass blocker

These work great as inline base blockers for my 3.5inch speakers. Tuned up my stereo and no more worries about too many frequency's. In line bass blockers are passive second line defense.... Use a proper crossover for active bass blocking!

### ⭐⭐⭐⭐⭐ Pretty Good
*by B***É on February 27, 2025*

They do well, allows the bass to cut through on your subs better when used on all 4 door speakers (not the subs) makes you feel the kick an attack more focused and centered that door speakers usually muddy up. vocals can blend better cause you can push the volume a bit more how you eq from your radio and amp make a big difference if you know what to do you can get a pretty okay sound stock nothing beats running an amp though. but easy cheap and good buy!
