I used a CR1 to eliminate the vertical axial room mode at ~60Hz from the speakers. It was easy to hear and measure ( using REW) the difference. This is with two different speakers. I did not realize a distortion reduction or improved volume overhead. Unfortunately the CR1 caused a slight haze and dynamic reduction, so I went back to the axial mode problem. The CR1 does have a great feature set and is probably the most liquid crossover on the used market in terms of price.
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?
