I agree. I run my Maggie 1.7s full range and my SVS subs crossover at 40 Hz. That seemed very low to me, but it was a factory, recommendation and it works beautifully. I have a Antimode on each sub and I run them is stereo. That made a big improvement over mono. For a while you will likely have them running too high and too loud, but you will find music with not much bass sounding better due to imaging. You will have a good time exploring new limits in your system. Many opine subs would sound better if driven from the power amp, not taking away any power, but making a better match to the amps' own sound quality. If you don't go with room correction, this is another way to play with the sound. Enjoy!
Subwoofer Crossover Question
What would be the starting point for Subwoofer integration with a pair of speakers that has the Frequency response below. Any layman explanation for what the -6db at 23Hz signifies and how this might relate to subwoofer crossover into a two channel music system, (two Rel Strata III's) will also be appreciated.
Frequency Response 28Hz to 25kHz ±2dB, -6dB at 23Hz
Frequency Response 28Hz to 25kHz ±2dB, -6dB at 23Hz
