Hey ASR! Long time listener, first time caller.
My main HT/ couch speakers are DIYSG Fusion 10 Pures at 98dB/W but I recently realized that when I built them back in 2012-2013 I royally goofed the crossover; and the woofer inductors are feeding each other with EMR so I am seeking to embrace the age of DSP rather than own up to my mistake. The woofers have a sensitivity of 98.6dB/W per Eminence (Delta 10A) and the CD is 107dB/W per B&C but it;s sitting in a SEOS 12. Both specced at 8-Ohms. The woofer has an impedance dip at ~200Hz-1500Hz where it goes from 7.1->5.2->7.1-Ohms. Tweeter is mostly flat from 1300Hz to 20kHz.
Has anybody ever used these to Chi-amp 2-way passives before? Is the componentry from unit to unit consistent enough to have two units form a sort of matched pair?
I am hoping to just bypass the volume pot and let these hang out on the backs of the cabinets (one per speaker) in a chain of: line out -> DBX PA2 -> PA3s (R-channel= tweeter + protection cap ; L-channel= 10" woofer). I have the original XO schematics, vituixCAD, 2-channel o-scope w/ SE probes and function gen, and a multimeter. Calculated spl should be 100+dB up to 5m listening distance using Amir's measurements of 27W real power into 8-Ohms. Just checking if these can handle, or if I am setting myself up to require a week's worth of REW and DBX tweaking. Thanks!
