Posted March 14, 201312 yr I just had a box built for my 2 icon 12's tuned at 30hz.I had it metered at my local shop.they said it was peaking at 40hz.is this normal?is it cabin gain etc.
March 14, 201312 yr Yea that's normal. I think its because the vehicle has a resonant frequency and gets louder at certain frequencies.
March 15, 201312 yr Author cool,I mean the box sounds great,not fussin just didn't exspect that much difference.lol curious
March 15, 201312 yr Your car and your box surely may not correlate in where they peak. In fact, IMO it sounds like ass. Of course it can help to utilize that information in competition but for music it sucks.
March 16, 201312 yr Author I know a lot of stuff rattles.I have no sound deading,if that is even the case.
March 27, 201312 yr The only way to "retune" your enclosure would be to rebuild it. However, if you are not getting the low end you are wanting then yes it would need to be tuned lower. However, if you tune lower you will lose some of that upper end you are currently getting. You will still likely "peak" spl wise in the same spot though or at least close to it.
