Low pass filter question

So you might not get your subs to sound decent at 150 even if you want to. Besides - bass blockers are 6db/octave x/o's. They'll still be playing freq's down around 100hz, just not as loud as 200. If you can get 80-100hz LP to sound good on your subs you should be good to go.
