Chris Posted February 20, 2007 Report Share Posted February 20, 2007 Double baffle IS nessesary for spl and really so the box doesnt break apart. the baffle is the weakest part on any box and to tell the truth, it REALLY isnt that hard to make it a double. Very quick work once you have the first one done. 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

pstone11 Posted February 20, 2007 Report Share Posted February 20, 2007 well, if you want to make it look better, run a roundover all over that port, at least even it out a bit with the box. Might change your tuning a hair if you even care, or know what it is. As long as it hits, don't matter I guess.

bernymac Posted February 20, 2007 Report Share Posted February 20, 2007 I say. if you decide you wanted to have the port at the bottom, flip the box upside down, and then double baffle top and bottom since you have to cover the first hole some how, then take a cutout and glue it, and fill in the crevice with resin or silcone. Then you'll have your port on bottom. =). Easy modification. But if it sounds good like that then w/e. But I say you need a double baffle also, your going to regret it if your subs break your box.

Ernesto Posted February 20, 2007 Report Share Posted February 20, 2007 Double baffle is a minimum when running two 18" BTLs... I know of some serious competitors that use 8 layers of 1" birch. Link to comment Share on other sites More sharing options...
thegr8cody Posted February 20, 2007 Author Report Share Posted February 20, 2007 instead of doin a double baffle can i just do like steve did and cut out around the speakers and put it on top,cuz i planned on fiberglassing the inside for support to 1998 gmc sierra h/u:eclipse cd3200 sub:dd9518g d1.5 amp:jl e300/4 sub amp:dd m2a front stage:id ctx65cs dc power 270 alt lots of kicker 1/0 Link to comment Share on other sites More sharing options...

Chris Posted February 25, 2007 Report Share Posted February 25, 2007 I think from what I read he's saying that he was just gonna cover up the port holes and baffle with some more wood. I'd just build a whole new box cuz that route is goin to affect airflow unless he resins and glasses the shit out of it. 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

Rocket City Bass Posted February 25, 2007 Report Share Posted February 25, 2007 I too suggest redoing the box. Maybe go it metered, play around with it some and just redo it. Part of getting loud is trial and error. Everything these guys have said is correct about the port and baffle. Build, test, rebuild, retest...gotta love it Link to comment Share on other sites More sharing options...
thegr8cody Posted February 25, 2007 Author Report Share Posted February 25, 2007 i was able to swap the port around cuz i never screwed that board in,i ran out of silicone and screws,and i dont get how your talkin bout not bein able to flip pieces if a box is built properly,i had the port at the top just so people can see the magnets until i got it finished,i kno there not straight cuts i gotta sand them even,im not the best cutter,and i plan on doing a double baffle im gonna make it like steves where the subs sit flush,and i plan on fiberglassing the inside 1998 gmc sierra h/u:eclipse cd3200 sub:dd9518g d1.5 amp:jl e300/4 sub amp:dd m2a front stage:id ctx65cs dc power 270 alt lots of kicker 1/0 Link to comment Share on other sites More sharing options...
