Like Danny Richie speakers, the spectral decay is fast. And the KEF Q100 has less problem at HF than KEF LS50 but I can see a very little resonance at 700 Hz -> it needs more mass and damping absorbent (mechanical) material like my loved and cheap TecSound SY70 (I have a lot of; if someone near Tarragona (Spain, EU) needs this material I can give you the one you need for your speakers by free).

Crossovers: Laying a Foundation


Passive vs digital crossover and more.

Semi-customizable, Professional Audio Converter Platform

...The dspMusik starts by using low phase jitter clocks driving all the data converters. The optional ADC incorporates very high common mode rejection / low noise balanced inputs and DACs with minimum phase anti-imaging filters (desirable to avoid pre-echo effects). Signals are processed by an audio-optimized 32-bit/40-bit floating point DSP capable of up to 384 kHz performance.
