January 23, 200817 yr If you run two actives it doubles the slope right? Like a HU at 12 and the amp at 12=24?...if you can get them set to the same frequency. But will make them harder to integrate with steeper slope.
January 27, 200817 yr Bandpass = anything between two given frequencies (high and low) is allowed through.Does that make sense? Edited January 27, 200817 yr by Dave Brooks
January 27, 200817 yr Bandpass is usually mids; you take out the bass (that goes to woofers) and treble (that goes to tweeters) at frequencies you need for driver/install/etc., and what is left goes to the mid. Or it could be a bandpass sub box that is tuned (ported) to produce only a band of frequency such as 30 to 90Hz. It could also be mid-woofers that would only be the higher woofer frequency (8"-6.5" woofer in a car door), or a dome mid that would be only the higher mid frequency as a dome does not go as low as a typical larger cone mid would. Either way, you will have a high and a low pass not just one or the other.
