And do these subs have a PEQ?
The built-in crossover range is 30 - 90 Hz. If you set the sub's crossover to 'out', it is flat up to several hundred Hz. The only issue with a higher crossover is localization. If you place the sub directly behind you, or a pair placed symmetrically behind you, you can crossover as high as 150 Hz without localization issues. If you get a single sub, and cannot place it directly behind you, and want to crossover high, place it against the front wall, between the two main speakers.
It has a ULF Trim that acts a bit like the Q control on our VTF series. Setting it to 50 Hz is like setting the sub to a lower Q - it will start rolling off at 50 Hz, but at a gentle 1 - 2 dB/Oct, so it's down around 4 dB at 15 Hz. If you want tighter bass, set it to 50 Hz, or if your room has too much low bass gain, do that as well.
