bassface Posted June 3, 2012 Report Posted June 3, 2012 I am currently making my ports for my box, and I have no choice but to make 2 separate ports. The specs call for 110 square inches of port 22.5" long. Now if i make 2 55 square inch ports will they still be 22.5" long? I thought it wouldnt matter because they added up to the same area but someone said i would need to recalculate the lengths. Can anyone shed some light on this for me.
bassface Posted June 3, 2012 Author Report Posted June 3, 2012 Ok they are saying if i use 2 ports instead of one port the length of the ports will be 2 times as long as a single port? Thats hard for me to believe but is this the case? That would be like 2 45" long ports wtf?
bkolfo4 Posted June 3, 2012 Report Posted June 3, 2012 Depends - If you are talking about a 60 sqin port vs. 2 30 sqin ports, no they are not double the length. If you are talking about a 60 sqin port vs. 2 60 sqin ports, yes they are double the length. You really have to just calculate length based on 1 or two ports if there is some different ratio between the sizes. Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.
bassface Posted June 3, 2012 Author Report Posted June 3, 2012 Thanks man, Thats what i was hoping to hear. Its just one 110 sq inch split in half to two 55 square inch ports because i got the convertible top motor in the middle of my trunk shelf.
