Bass Blockers?

I saw something called a base blocker at HIFI Sound Connection, and I have no idea what they are. Can anyone enlighten me?

you install it on the speaker wire before the speaker then it blocks out the lower frequencies.

Sag 3 is right. Just be aware that these are capacitors, if you are running these straight off of deck power they can rob power. A better bet would be to get a 4 channel amp that has built in electronic crossovers. I wouldnt do bass blockers unless you have 4",3"or 4x6 speakers.

They cost 10 bucks or so, go to an electronics store and buy them for 1 or 2 bucks.

they are a 1st order (6db/octave) crossover. they help, well, about 10 dollars worth i guess.

bass blockers FTL... i used them only in extreme cases... not worth it IMO

Or you could just figure out what value capacitor you need based on your speaker's impedance and desired highpass frequency, and pick them up at an electronics store. Typically cheaper this way, since those bass blockers are nothing more than a capacitor.

Would you happen to know that equation squeak?
