bass blockers

What sized bass blockers are suitable for 4x6 and 5 1/4 speakers?

I picked up some bass blockers from bestbuy in the states, they say their for small speakers and are rated for 3000hz @ 4ohms. Tried some google searches and found this recommendation from crutchfield.


If you like it loud, protect your speakers from bass distortion and enjoy cleaner sound with Bass Blockers. Each Bass Blocker handles up to 50 watts RMS with a 6 dB per octave roll-off. You'll find some general guidelines below for matching Bass Blockers to speaker size. For smaller speakers (3-1/2"s, 4"x6"s, 4"s), the 600 Hz Bass Blockers work well with low-powered systems, while the 800 Hz Blockers are a better choice for high-power applications.

Speaker Size Cut-off Frequency


Any help is appreciated, thanks!

6-1/2", 5"x7"/6"x8" 150 Hz
5", 5-1/4" 300 Hz
3-1/2", 4", 4"x6" 600 Hz (low power)
3-1/2", 4", 4"x6" 800 Hz (high power)

These models come fitted with easy-to-use quick-slide connectors that make installation a cinch. There's no splicing or crimping just slide one of the Bass Blocker's connectors onto your Crutchfield speaker harness and the other Bass Blocker connector onto your speaker's positive terminal.

Cut-off points are at 4 ohms. If you use 8-ohm speakers, the cut-off point is half the listed frequency.



Any help is appreciated, thanks!

Why do you need bass blockers? Are you getting low end distortion from your speakers?

If you have your crossovers set properly you shouldn't really need them. (Unless you're in one of a few specific situations)

Yes I'm getting distortion out of the rears. I'm just concerned that the bass blockers I picked up will only deliver pure highs and zero mid bass. The speakers being used are ones from an e30 or e28 premium sound setup. I have this installed in my e21 btw. I've read that these speakers can sound decent when ditching the factory amp and supplying power w/ a mild aftermarket amp. I also have 2 audiobahn 10's supplying bass in the rear. Although, I'm thinking of downsizing to a single 10". I just want some decent sound quality w/ some bass and no trunk rattle boom.

Thanks
