imupabove Posted May 2, 2010 Report Share Posted May 2, 2010 hello. i have 2 alpine type r's. i want to make a ported box built for mainly spl but still maintain sound quality of course. i have no clue where to start. i have no tools except a drill and some handy tools. i messed around with that RE calculator but wasnt sure if i was things correctly, is it a useful tool? is that the only tool i need for my measurements and cut outs? should i double baffle it? im really serious on making this box, even though i never built one. i posted this same topic a while back but no success yet :[ but its cool. btw, i got a pair of 12" RF T1's and some day i want to use those with the same custom box. i want to build a universal ported box so any 12's will be loud in the box. thank you for your time. car:1993 camry sedan amp:rockford t10001bd trunk measurements: not yet taken Quote iDA-X200/Clarion EQS746 RF T500-1bd (2) 12" RF HX's Kicker 350.4 Alpine & Polk Speakers Stock electrical Link to comment Share on other sites More sharing options...

I cant say that that will work for all subs as subs are just designed different. maybe you will be lucky and it will work with your T1's. But I do stand behind marlo's specs for the type r's:) Edited May 2, 2010 by 98crewcab Quote 06 2500hd, 6.0L, 4l80e, 4wd, (muah work truck) 7" BDS HC lift kit (5) 37x13.5R18 Toyo Open Country M/Ts (5) 18x10 Moto Metal MO962 tablet in lieu of deck blue tooth interconnect to soundstream eq (for volume control and bass control) 4 Alpine type r 10's 6 cubes net, 80sqin's port, tuned to 33hz 2 brutus brx5000.5's 2 pairs 3" polk audio for a pillars 4 pairs polk audio 6.5 comps 1 pair 8" polk audio for mids 2 xspower d3400 batteries.....learning alot from meade and his circle of some of the baddest installers ive seen- thanks guys, for not being so cocky and posting the way it should be done!P.S.

98crewcab Posted May 3, 2010 Report Share Posted May 3, 2010 have you heard about that RE calculator? should i use that to build my box? since you said "2.3 cu. ft.", do i times that by two? I heard that the RE calculator was a little off. I used 12volt.com for my port dimensions. and it seemed to work out pretty damn good. and yes. multiply by two....so 4.6 cubic feet after all displacement of port and subs. and 60 square inches of port. double check with the guys here just before you build to make sure the port length is right for the tuning you want. stay with 60 square inches, but until I know the size of your box, dont know the length of the port Quote 06 2500hd, 6.0L, 4l80e, 4wd, (muah work truck) 7" BDS HC lift kit (5) 37x13.5R18 Toyo Open Country M/Ts (5) 18x10 Moto Metal MO962 tablet in lieu of deck blue tooth interconnect to soundstream eq (for volume control and bass control) 4 Alpine type r 10's 6 cubes net, 80sqin's port, tuned to 33hz 2 brutus brx5000.5's 2 pairs 3" polk audio for a pillars 4 pairs polk audio 6.5 comps 1 pair 8" polk audio for mids 2 xspower d3400 batteries.....learning alot from meade and his circle of some of the baddest installers ive seen- thanks guys, for not being so cocky and posting the way it should be done!P.S.

hamel52 Posted May 3, 2010 Report Share Posted May 3, 2010 i would download the torres calc man its pretty simple and easy right here on the forum you should try it i'd go 3.5-4 cubes tuned to about 34hz i had the same subs and set up and it pounded try about a 4in port tuned to 34 and you will have the right amount of port area and it will sound real nice, good luck Quote Link to comment Share on other sites More sharing options...
