YukonXL04 Posted August 25, 2018 Report Share Posted August 25, 2018 Ahh I see. Yea I plan on building 1 for 2 SSA F8Ls here in a couple months. Going to follow all the seat curves, and the box will take up about 2/3s under the seat, the other 1/3 I will leave the top off so I have some storage still. Looking at building a 1.5 or 2" seat lift as well. But with all the curves, it's hard to calculate the airspace correctly, so I will build the box, then measure the airspace, then add a 4" flared aero port and adjust length as necessary. 18 Sierra 6.2 Z71 : 3 F8L's, DD M2a @.67, 1.95@33 05 TL build log SOLD 04 YukonXL : jvc kw-v51bt , RE 6.5c, 4 jbl gt5 12s, Memphis pr1000.1 5.5 cu.ft. sealed Link to comment Share on other sites More sharing options...
mestapho Posted August 25, 2018 Report Share Posted August 25, 2018 A 1.4 cube net box, 15 sq in port, 35 Hz - 18 inches long port volume is .16 ft3, not counting the volume of material used to create the port. A 1.4 cube net box, 4 in. aero port, 35 Hz - 17 inches long port volume .12 ft3 a 4" aero port will need about 6" diameter of real estate on whatever face it ends up on.

shredder2 Posted August 25, 2018 Report Share Posted August 25, 2018 Looks to me like with the dimensions you gave in the original post that you'll need to raise the front & rear height .5" to get magnet clearance... (.404" exactly, I'd go .75" at least to make it easy) unless you invert the subs , I just don't see another way to have a front facing baffle. I got 2.46ft3 net before displacements with those measurements so you definitely got the room to do it right IMO. Link to comment Share on other sites More sharing options...
