Ok I can't find a decent box...I want something tuned to 33hz. The specs for the sub are listed below if someone can help me. Would 30hz be tuned too low? 40hz just isn't right for me....I want a little lower bass. 12" subwoofer with dual 4-ohm voice coils » injection-molded polypropylene cone ...

So the amp is pushing more than 1100watts? What about the subsonic filter.........it goes from 20hz to 50hz the box is tuned to 40.....I read to set the ss filter to 10hz below the box tuning....

The amp I have pushes 1100 watts max..........I only have the gain 1/4 the way up.......the bass boost is down almost all the way.....they are 800 watt a piece subs......rms is 400....so together rms is 800 for both of them.....must be clipping? 32hz sounds good.....what about 30? I found a nice sub...

Okay what tuning do you guys recommend.....I was thinking between 30-33hz because the box I have now is 40hz and it doesn't hit very low at all.

From everything I've came up with I would need a slotted port that is either 2.5" x 12.5" for the opening and 20" for depth........or for spl..3.0"x12.5" opening and 20.5" depth. The port on the box I have is only 14" deep.......I think if it was longer I would get...

Can anyone give me the specs the box would need to be, I need depth, length and width, as well as the vent size. I'm just trying to figure if thats the prob. I was reading that if the box is too small I can add some polyfill to help out with that. Anyone?

I'm going to blame the box, maybe it's not the right specs for the subs I have. The place I bought it said it was the same as my old box, I had the probably 03 version of the kicker comp vrs in the subzone/orion vented box where the subs go in from each end. He told me it's the same box but built di...

Is there such a thing as having too much mounting depth? My subs call for 6 5/16'' mounting depth, and my box has between 9 1/2-10" of mounting depth.

I've heard that if your speaker wires are different lengths that could make them have the flutter effect....?

Thanks for all of the idea's. I'm going to get started checking a few of these things.
