Bass Blockers, do they work?

Need to find something around 80-100 hz.

Harrison Labs makes some inline RCA crossovers that may be worth a look.

I have not had very good luck with wired in-line bass blockers, but the fail could be related to other cheap componets in the signal chain.

Why not get a better passive crossover?

Also, I agree with other posters about the 400 hz crossover. I'd only look into that for a midrange or something, not a midbass.

Bassblockers are 1st order crossovers at 6 dB/octave. It's not going to "block" must bass if you get one for say 120hz. It will only be 6 dB down at 60hz and 12 down at 30hz.

To be effective at taking away the low end and sparing the speaker, you'd need it to start pretty high. 400hz would be a safe bet.

If you want to keep your midbass, you need to go active most likely, or develop a 3rd or 4th order HP passive crossover. Not too hard to do something like this generically.

If you wanted to get a very rough 80hz 24/db crossover, run two of those Part-Express passives in series. Each one will knock down the lower frequencies by 12db

That's the easiest solution to your problem. I might even do that at 100hz

Edit:

I went with 200hz and down should do what i need
