Menace89 Posted November 4, 2007 Report Share Posted November 4, 2007 Both RE L-port calculator and carstereo.com says that my box needs to have 1.783 cu. ft. and be tuned to 22.76Hz (I figured doing 23Hz wouldn't hurt) Will a box tuned to 23Hz would even sound good? If anyone want to check it to make sure I got it right, I have 2 12" Cerwin Vega V-Max subs(but im doing separate box and port for each) specs on subs are: Fs-28Hz Qts-0.48 Qms-4.3 Qes-0.54 Vas-0.977 cu. ft. Xmax-17mm Cone area-70.8 sq. in. I already have the box designed and everything, I just wanna make sure a box will sound good tuned to 23Hz before I build it.

zaxfire69 Posted November 4, 2007 Report Share Posted November 4, 2007 23hz is LOW...Really depends on your subs recommended Enclosure specs..What do your subs call for as a recomended enclosure.. http://www.cerwinvegamobile.com/CVM_enclosures.html Here are the subs recommendations for enclosure specs So no..23 hz is not good Link to comment Share on other sites More sharing options...
Menace89 Posted November 4, 2007 Author Report Share Posted November 4, 2007 Manual says 1 cu. ft tuned to 37Hz and the web site says 2.5 cu ft. tuned to 35Hz but with ony 20 sq in of port. so i dunno what I wanna do cuz 20 sq in of port sounds small Link to comment Share on other sites More sharing options...
01xtreme Posted November 4, 2007 Report Share Posted November 4, 2007 I think you would have a pretty flat response, but you would lose shit tons of output.

Menace89 Posted November 4, 2007 Author Report Share Posted November 4, 2007 So then should I use the 20 sq in port on a 2.5 cu ft. box or should I use around 30 sq in? Link to comment Share on other sites More sharing options...
Guest Dylan Dude Posted November 4, 2007 Report Share Posted November 4, 2007 I think you would have a pretty flat response, but you would lose shit tons of output. that's what I was thinking too. Link to comment Share on other sites More sharing options...
01xtreme Posted November 4, 2007 Report Share Posted November 4, 2007 So then should I use the 20 sq in port on a 2.5 cu ft. box or should I use around 30 sq in? I would download WINisd and spend a little time modeling up your subs and figure out which would work best considering what you are llooking for the subs to do. 30sq in of ports does seem a little small, but then again I have never used those subs. either way I would ditch the 23Hz idea. 30 is about as low as I would think of going for a sub box in a car.
