kirill007 Posted April 3, 2010 Report Share Posted April 3, 2010 I think it's a huge load of port noise, does the sound get's quieter if you turn it down at like volume 10?

__d_a_v_i_d__ Posted April 3, 2010 Report Share Posted April 3, 2010 it sounds like the sub when the bass hits, that the surrounding of the woofer is hitting the port. or that the port is actually flexing with the air and is making the sound Quote Chevy Impala Shocker Sigs / TC Sounds 12s Sundown NS-1 | SAX 100.4 Sundown Neos | Dayton Audio Neos ETCCC ETCCC ETCCC My YouTube ---- Subcribe!!

alman101 Posted April 3, 2010 Author Report Share Posted April 3, 2010 I think it's a huge load of port noise, does the sound get's quieter if you turn it down at like volume 10? It has the same "rattle" but not as violent how big is the sealed box and how big is the ported ? i'll try and help you out there too I believe it was 0.9cu.ft sealed and 0.6cu.ft ported I took the port out and I think the sound is coming from the woofer itself or something else inside, I don't think its the port anymore Quote Link to comment Share on other sites More sharing options...
uhoh_45 Posted April 3, 2010 Report Share Posted April 3, 2010 yeah your ported area is to small thats what it was you need anywhere from 2-2.7 cubes ported for this to work tuned to 60 hz Quote R.I.P!

basshead4life Posted April 4, 2010 Report Share Posted April 4, 2010 just swap the port and the terminal cap so the ported section is bigger and the sealed is smaller and see what happens. may give a little more control on the sub Quote Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana.

alman101 Posted April 4, 2010 Author Report Share Posted April 4, 2010 I am unsure what to do, I only have a 4ft x 4ft slab of MDF left. I can either make a ported box with that or wait 2 weeks for my next pay check to go get another slab at RONA. Quote Link to comment Share on other sites More sharing options...
