After CAF2018 took the feedback from the show listeners and did a new DSP crossover design for The Monoliths speakers. This was the crossover design used for AXPONA 2019. This was run in the room on both the dspMusikLCD 2x8 on Friday and the dspNexus 2x8 on Saturday and Sunday.
To improve the power handling for the BG NEO10 midrange and GR-NEO3 tweeter implemented 8th order (48dB/Octave) Linkwitz-Reily crossover filters for all slopes used. The High Performance digital crossover filters in Audio Weaver that run on the dspMusikLCD 2x8 are excellent sounding topologies that I had tested using headphones and are used for the design.
After listening tests with the new design of the crossover for the speakers, it was a large improvement in sound quality over the original design.
Since we knew we would also be dealing with small room acoustics, MathAudio RoomEQ was setup on the HAL MS-5 Music Server in Foobar2000 music player software. After the speakers were setup in places that room modeling suggested, RoomEQ acoustic measurements were done and the new High Precision mode was used for all music playback. The results spoke for themselves.
Glad listeners were able to hear the system and give their responses to the results. The comments were very positive indeed.
