Dahlquist DQ-LP1 Crossover
Cleaned and tested
The Dahlquist DQ-LP1 crossover combines an electronic circuit for low bass output and a passive circuit for the frequencies above the crossover point.
Thus, the upper range remains pure and undistorted, with no alteration whatever of clarity and depth imaging.
Features of the DQ-LP1 include:
Variable frequency electronic low-bass sections with 18dB/octave slopes
Three cascaded stages with staggered time-constants for non-ringing
Low phase-shift curves at any frequency setting
Completely passive high-pass sections which can be custom tailored for any bass roll off frequency
Independent adjustments in each channel to compensate for room placement
Separate output circuits for stereo and mixed center channel bass modules
Level controls and A-B comparison switches
Low pass crossover: 40 to 400Hz
Slope: 18dB per octave
Total harmonic distortion: 0.005%
