They might look out of place, but for me, without a WAF to contend with it would be worth a try. I've never used a minidsp(only wish I had one). I have a BFD, but I would try a filter centered at 45hz with a negative gain of -5 to -7 with a fairy wide "Q" value to cover from about 30-60hz. This will pull down in a "v" shape at the center frequency. The Q determines how wide the V is. What is your crossover set at? And what are your mains. Btw, if anyone else has a better suggestion, c'mon in. That's where I'd start, and see what happens.
