jayjay6888 Posted September 25, 2008 Report Share Posted September 25, 2008 (edited) i see that your putting an AQ2200 to it.. is the BTL fully loaded and do you plan on putting more power to it later if so smaller is better definetly i think your latest demensions will put you at a mid to high 6 cubes after all displacement b/c those are the measurements that im using to design my box for my 18Q except 2" shorter Edited September 25, 2008 by jayjay6888 Quote 1 Fi Sp4 18 Crescendo 2k selenium mids audioque supertweets Hifonics for mids and and highs 1/0 power and grounds ---> on the way singer alt and possibly another 2k depending how sub likes 1 2k Link to comment Share on other sites More sharing options...

98_EXPIDITION Posted September 26, 2008 Author Report Share Posted September 26, 2008 Thats correct the amp is a AQ 2200, and yes, the BTL 18 is fully loaded, and no, we really don't plan on putting more power to it later. Where can I find this amatt's calculator? Thanks, Dan. Quote Link to comment Share on other sites More sharing options...

98_EXPIDITION Posted September 27, 2008 Author Report Share Posted September 27, 2008 Alright I'm pretty set on using those dimensions of 36"w X 20"h X 24"d, and I don't have excel so I can't play around with the calculator. How do I go about figuring out the port size. And do I use a round port(s), or built it vented? Quote Link to comment Share on other sites More sharing options...
98_EXPIDITION Posted September 29, 2008 Author Report Share Posted September 29, 2008 Guys, I have been playing around with RE's online ported box calculator and pretty much have it all figured out. . http://www.reaudio.com/speaker_box/LPort_Box_Calc.html I have a question though. The calculator gives inputs for 2 square port lengths. My question is, does the port have to make a 90* turn in the box? I am able to get my desired frequency with only one port board and no turn internally, but I'm not sure if the turn is needed or not. Thanks, Dan.

caddylac Posted September 29, 2008 Report Share Posted September 29, 2008 ive only built one box so far so dont take this to serious. im still learning the program too. w-36 h-20 d-24 port hieght-18.5 port width - 5 port length 1 - 18.25 port area - 92.5 box volume - 6.884 tuned frequency - 32.4 Quote Link to comment Share on other sites More sharing options...

AI James Posted October 1, 2008 Report Share Posted October 1, 2008 ^^side firing ports for the good sounding win. which BTL? this year's or last year's model? rule of thumb with the ports, aim for 7 - 11 sqin of port per cubic foot of box. don't be scurred of the calculations, though. for internal volume, all it is, is length times width times height, then divided by 1728. shazzamn, you've got volume in cuft. Get in the vehicle, take some dimensions, and give us more to work with in terms of "how much room is he willing to give up" using your formula for a 5 cube box thats 35-55sq in port kinda seems small imo Quote Link to comment Share on other sites More sharing options...
