bmwking Posted October 24, 2018 Report Share Posted October 24, 2018 Hey guys, I made a post in the last year (not expecting anyone to remember) looking for help making a box for a buddy's '14 F150 supercab for a CT meso 8 in an under seat box on about 900rms. You guys all gave lots of good advice and help, so thanks for that! I finally got around to getting the sub from him to do actual physical measurements and have figured out that the sub just wont fit (some of you said this too, I just had to see for myself). So I got to thinking, what if i could do a ported or even a t-line box in the same space for 2 of the meso 6.5s? The available space (he won't lift the rear seat) is: 33" length 11" depth 8" front height and 6" rear height I'd be pretty interested in doing a t-line if possible, otherwise ported will be the way to go. So what do you think? Possible? Maybe someone could help with the design as I have no clue about t-lines ? Thanks guys! Link to comment Share on other sites More sharing options...
Joe X Posted October 25, 2018 Report Share Posted October 25, 2018 The line length for a 40Hz tuning would be about 85", assuming a single sub Sd of 110 square cm, the line volume using two subs would be 85x34 = 2890 cubic inches or about 1.6 cubic feet, your gross volume with your dimensions amount to 1 cubic feet so a traditional non tapered design would not be possible in that space. If a lower efficiency tapered design was possible, building it would not be very easy with that slanted top. On the other hand a ported box may be possible if you could find 3.5" - 3.75" PVC pipe.

Joe X Posted October 26, 2018 Report Share Posted October 26, 2018 You could do the following or something like it as feasible, bracing is necessary as it uses 5/8" wood : Enclosure Specifications: Fb = 38 Hz Vb = 0.8 ft^3 * All Dimensions in Inches. * Wood Thickness is 5/8 for all Parts. Port Quantity and Dimensions: Number of Ports = 1 Pipe Port Diameter = 4 Pipe Port Length = 27 Link to comment Share on other sites More sharing options...

bmwking Posted November 5, 2018 Author Report Share Posted November 5, 2018 @Joe X Just wanted to say thanks again, it came out great and sounds even better! I used 1.25" dowel rod for top to bottom bracing in the middle too. Link to comment Share on other sites More sharing options...
