I'm using a MiniDSP SHD as an electronic crossover and also using DIRAC. Digital signals pass through to my Benchmark DAC3, and the sub signals go direct to my powered subs. I come from the pro audio world, so using electronic crossovers/DSP is SOP.
Electronic cross-over on pre-amp out, to split signal to subwoofer and bookshelf speakers
I have a 50 W amp for 86 dB bookshelf speakers.
I really want to keep both amp and speakers.
My idea is to have an electronic crossover on preamp out, split the signal say at 80 Hz - Send the lower electronic cross over out to a subwoofer. Send the high crossover out to my existing 50 W power amps.
This would extend speaker frequency range to subwoofer capability - say 25 Hz, reduce the power amp load and allow to play the bookshelf speakers a bit louder,/ have more headroom.
I am sure others have already done. What cross over did you use? Was it successful?
