Harm it...I would say its possible if you dont have a sub-sonic filter set. To my knowledge, and I could very well be wrong, but the SSF prevents it from bottoming out and I'd assume that if it bottoms out frequently that it could expedite it's failure.

I wouldnt play Tones that low in a box tuned that high (Im taking j3bus2k3's word on the tuning...cause im too lazy to do the math) You will run into problems with the sub bottoming out. unless of course you have your SSF set properly

sorry man... If you need a design they're are plenty of top-notch designers on here, you just need to ask who's better first. Moe Lester, Saywhat?, PV Audio, JordanTyler, just to name a few of the most respected although Moe isnt doing any ATM...

My first guess is that it may be bottoming out...but to be honest, I have no clue.

 

[SQBubble 10+ year member]

nahh i dont think so, its really an anoying sound that always come out when there is any kind of bass, maybe the voice coil!!?? or somethin'...

edit*and there is no bass at all too

Hmm...maybe some intereference through the RCA's? Bad ground?

j3bus, you added a bit too much when figuring effective port length, but your tuning calculations are right on.

Effective port length is ~15.5-16" and you've got a tuning right around 47-49Hz. This is assuming 3/4" MDF construction and the first 3/4" of the port being the "front" of the box (ie not causing internal displacement).

In other words, a box tuned entirely too high for daily driving. You'll reach mechanical excursion limits easily with typical bass found in rap. It sounds like you did that, and screwed up the sub //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Well, when he gave me 13.5" I added the 4" for the bend, .75" for the L2 and then end correction of 2"...I thought I was being generous...
