Dahlquist LP-1 Passive/Active crossover


Does anyone have any expereince using the Dahlquist LP-1 Passive/Active crossover in place of the stock passive crossover with Magnepan 20R speakers? I have been using a Bryston 10B "standard" active crossover to replace the passive crossover in my 20Rs setting the high pass at 300Hz/6db slope, and the low pass at either 100Hz/12db slope or 150Hz/18db slope. I recently acquired the DQ LP-1 and was curious if it would work.

I have a Dahlquist LP-1 that I have used for many years. I found that setting the frequency to high will make the bass not sound right, to much bloom. I have mine set on 92 at this time, the level at around 1 on a clock and the equalizer at zero. I suggest starting at 12 o’clock on the level and equalizer, and around 40 on the frequency. Slowly increase the frequency until it sounds right to you. When you feel that you have found a good frequency setting, try slightly adjusting the level control slightly. In time you will find the “sweet spot” in you bass. When you play song that has very powerful low frequency’s, use this as a maximum reference point for your bass and set the Dahlquist LP-1 to your liking. It will take many tweaks.

I would never give up my Dahlquist LP-1. I use a Hafler XL280 driving a pair of DQ 1 subs with it. I have total control over the bottom end and I will still occasionally slightly tweak the dials.

You want to enhance the bass in regards to the room and other speakers, not overpower the bottom end. I get many compliments on how tight and controlled my bass sounds.
