    Home Theater System Recommendations
    I recently upgraded my AV Receiver to a Denon AVR 2312ci I found at a thrift store for $30! It works very well!

  3. Please explain: RCA active filter / crossover on sub

    Home Audio Subwoofers
    I’m looking for a sub that has left and right RCA in and out, and further that acts as an active crossover (thus not sending the bass that the subwoofer is handling to the main speaker amps). The reason for this is that I have a great stereo pre-amp with only one pair left and right RCA...

  9. REW for calibrating a full range four way active system

    REW Forum
    I am trying to calibrate my four way miniDSP OpenDRC-DA8 based speakers. My first step is to balance the four drivers in the miniDSP panel. What speaker response should I be aiming for? Flat response sounds horrible; I balanced the drivers using a 3db roll off per octave using the EQ panel of...

  12. DSP / Active Filter Types / Slopes

    REW Forum
    Is there any kind of discussion out there on filter types and slopes, advantages / disadvantages? I recall from my passive crossover days that certain filter combinations had certain characteristics, and I assume the same runs true for active dsp crossovers, but I'd be interested in a good...

    DIY Speakers
