200hz sub

[regal]

I think I already know the answer but wanted to know if there are any DIY sub designs that would sound good with a rediculous
200hz crossover. This is because I am setting up a Pioner 563 uni-player based system which directs bass under 200hz to the sub with DVD-A

Higher cutoff may cause distortion at high levels.

This uniplayer has a single sub output at 200 Hz, or stereo? At 200 Hz, a single sub would screw up your imaging by being an easily localizable source. A stereo pair would serve you well. Does the bass management in the uniplayer allow the sub output to be disabled?
