mxman38 Posted January 9, 2010 Author Report Share Posted January 9, 2010 I tried callng DJ but hes closed for the weekend, so is this going to be tuned to low or will it change once its in my truck? Quote Link to comment Share on other sites More sharing options...
Sampsonite Posted January 10, 2010 Report Share Posted January 10, 2010 Good to go. 7:1 port ratio, 15in^2 of port per 1ft^3 (assuming you will be somewhere close to 12 cubes after displacement) is the sketchup drawn to scale? It doesn't look like a 5" port width. jw Quote --Sampson 816-591-6592 www.kcrimshop.com Link to comment Share on other sites More sharing options...

Will 30 Hz be to low of tuning for these woofers? whats a doll rod??? is that what those girls dance around up on the stage. :01nocomment8so: -scratches head in wonderment as to why the U.S. follows all other countries in academics!

mxman38 Posted January 10, 2010 Author Report Share Posted January 10, 2010 (edited) yeah but even if i open the port up to 5.5" i will be at 32 HZ, i dont know how close i will be to the woofers with the port.

LoudBlazer Posted January 10, 2010 Report Share Posted January 10, 2010 Shortening the port some should raise it, can try 32 I dont see why it would hurt the subs. Im not a sub builder so I couldnt tell ya lol Quote 1997 2 Door Blazer Bagged & Body Dropped SBC/TH350 Link to comment Share on other sites More sharing options...
mxman38 Posted January 10, 2010 Author Report Share Posted January 10, 2010 yeah i could shorten up the port a tad, i never thought about that... i could probably go a quarter inch wider on the port, then like 2 inches shorter. Quote Link to comment Share on other sites More sharing options...
Gotloud555 Posted January 11, 2010 Report Share Posted January 11, 2010 Look good from the photo but 14.5 would be better after port, bracing, and woofer displace. When you add those in the that box will no longer be 14.5 and those 4 15" choking.. Quote Link to comment Share on other sites More sharing options...
