    What is Bandpassed???

    I just thought I knew a thing or two about audio, until I came to this forum, then I realized that my knowledge is severely limited. Never knew there was so many details involved. I guess I dodged the bullet on many occasions in the past. Look here, I'm a die hard CV fan, and am looking into purchasing a pair of CLS-215's. They are a dual 15 set up with 6.5 inch mid and two inch tweeter. I sent CV an email to find out if both 15's are devoted to the low end, or is one devoted to the low end, while the other is tuned to the midrange. This was his responsn, and I quote: " Neither of the woofers are bandpassed, as there is a dedicated midrange." What does that mean? I need plain english. Thanks again.

    My understanding of the terminology is that you can have filters that are

    1) High pass = passing frequencies above a limit and blocking those below

    2) Low pass = passing below a limit, blocking above

    3) Band pass = passing a range between a high and a low limit.

    Alternatively I suppose a bandpass is something that let's you backstage?

    Like Nodinoff mentioned, bandpass just means a range of frequencies inside top and bottom end filters of sorts.
    Woofers aren't usually 'bandpassed' in this sense (though there is an acoustic filter at the bottom end of the woofer technically), they run full range below the low-pass filter (or high-cut if that makes more sense to you). Tweeters run full range above the high pass (low cut) filter. Midranges operate in a pass band.

    For those speakers, I would think the woofers handle bass, midrange handles mids, and tweeters highs - 3 way in other words.
    Nothing wrong with that.

    That's awesome! Thanks for the clearing that up with me. I guess now that I will have to get massive amps to drive those hogs. Thanks again!
