[QUOTE="calebkhill, post: 8063686, member: 647857"] What speakers also. Lpf blocks highs Hpf blocks loWs. Band pass filter (bpf) let's a RANGe of frequencies through to a speaker. Sub uses lpf. Usually set at 80hz. This means the filter will block anything over 80hz from going into you're subs. mids. Are they coaxial or is it a component set. Coaxial speakers usually have hpf set at 80hz. This means anything under 80hz will not pass to the speakers, and the crossover built into the speaker will hpf the tweet in the middle. If you have a component set, usually the mid is band passed at 80hz-3.5khz, and the tweet hpf is set at somewhere around 3.5khz. Make sense? [/QUOTE]
