System Goals: Integrated 2-channel/HT, fully horn loaded (very low modulation distortion), phase and group delay growth. No tube amplification, passive crossovers or bass reflex ports.  Very high accuracy/dynamic sound reproduction.

 

System Strengths: Fully EQed, time/phase-aligned crossovers for each loudspeaker using active digital crossovers. All drivers/loudspeakers time aligned, manually EQed, and crossed using fractional order crossover filters for an overall system frequency response of 14 Hz--20 kHz ± 1.5 dB, acoustic phase response within  ±90 degrees from 100 Hz to 20 kHz (at listening positions using psychoacoustic smoothing).
