System Goals: Integrated 2-channel/HT, no tube amplification, no bass reflex ports, fully horn loaded for very low modulation distortion, very low phase and group delay growth, and high accuracy dynamic reproduction.

System Strengths: Fully EQed, time/phase-aligned crossovers for each loudspeaker using active digital crossovers (Xilica XP-8080 fronts, miniDSP 2x4 HD surrounds). 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.

Signature

"...it will be shown that loudspeakers are the single most important element in sound reproduction. Electronic devices, analog and digital, are also in the signal paths, but it is not difficult to demonstrate that in competitively designed products, any effects they may have are small if they are not driven into gross distortion or clipping. In fact, their effects are usually vanishingly small compared to the electro-acoustical and acoustical factors" F. Toole, 2018, Sound Reproduction the Acoustics and Psychoacoustics of Loudspeakers and Rooms, 3rd ed., chap. 1.6, pg 16.
