    Bass blockers Q

    What are these exactly and how much do they run? Where can I pick a pair up? Am I right in understanding these can be used to block the bass at certain ranges on my front speakers? I would like my fronts to play mids and highs only..

    Bought mine from Crotchfield.

    A bass blocker is just an AC (non-polarized) electrolytic capacitor. A capacitor's impedance goes up as frequency goes down. You use them to keep bass out of your midrange speakers.

    I'd give you the formula for calculating what size you need, but it's a lot simpler to just order them by the cut-off frequency and speaker impedance. The ones I got are for blocking 150 Hz at 4 ohms.

    they just cut out frequencies below a certain level (at best buy we sell either 200hz or 300hz). not much too em... i think they are the devil if you have nice coaxial speakers...

    depends on the component set, and what the crossover in the set does. if it just splits the signal between the two speakers (just a generic crossover), then yes, i'd use bass blockers... but if it is a crossover designed for those speakers, it will most likely cut out those frequencies automatically. at least that's what i think anyway...
