You'll need an fmod if your going to be porting it that high.

i'd rather just get a good xover w/ a SSF on it.

You don't need one, but your subwoofer may be damaged by tones below 26.25 Hz ...

hey jmac how do you figure out what tone would hurt the sub? My box is tuned to 25hz so what would hurt that?

you should be safe up until half an octave below tuning freq

You will be perfectly fine //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

People place too much importance on subsonic filters. The key lies in knowing your program material and knowing how to operate a volume knob //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i look at the sub and ask myself "does my sub look hurt?"

if it says no...i "set it and forget it!" (

I have my 5.5cu' box tuned to 26Hz for my 3 12's w/o a ssf....never a problem. The A7HC has noe built in on it, but when I turned it on, it sounded like azz. (I like it low)
