plush4318 Posted December 2, 2015 Author Report Share Posted December 2, 2015 Ok, so. What if I used these dimensions on a new box: W 36" H 14" D 19" thickness still at 1" and used the similar port except on a different side then the subs. W 2.5 H 10 D 14 Tuned to 33 hertz? (is that even good? or should I tune it to something else?) Would this work? 04trailblazer XS d3400 XS xp3000 Pioneer 80prs 2 pairs of DD AW6.5 mids 2 pairs of DD AT28 tweeters DD SS4A DD M1D DD 3518sc in custom kerf port box 2 runs Tspec 0/1 wire Link to comment Share on other sites More sharing options...

(is that even good? or should I tune it to something else?) Would this work? Not well it won't. You are still really low on port area, you need at least 40 sq in and even more would be better. Have you considered not using 1" panels? 3/4" panels will work fine with proper bracing and will save you some space.

plush4318 Posted December 2, 2015 Author Report Share Posted December 2, 2015 I'm not opposed to 3/4 inch, I was just trying to come up with something on my own, working backwards. What would the dimensions have to be of the box at 3/4 thickness? And port dimensions for that particular size as well. I also just assumed around 33 hertz tuning would be where I want to be from reading other threads. 04trailblazer XS d3400 XS xp3000 Pioneer 80prs 2 pairs of DD AW6.5 mids 2 pairs of DD AT28 tweeters DD SS4A DD M1D DD 3518sc in custom kerf port box 2 runs Tspec 0/1 wire Link to comment Share on other sites More sharing options...
Joe X Posted December 2, 2015 Report Share Posted December 2, 2015 This you could do for a trailblazer (like in your sig) if this helps you some,. subs up firing or rear firing (as shown below): Link to comment Share on other sites More sharing options...
plush4318 Posted December 2, 2015 Author Report Share Posted December 2, 2015 Thanks joe. Are all the pieces in the corners necessary if the subs are being top mounted? 04trailblazer XS d3400 XS xp3000 Pioneer 80prs 2 pairs of DD AW6.5 mids 2 pairs of DD AT28 tweeters DD SS4A DD M1D DD 3518sc in custom kerf port box 2 runs Tspec 0/1 wire Link to comment Share on other sites More sharing options...
plush4318 Posted December 2, 2015 Author Report Share Posted December 2, 2015 I guess a more important question is, would those box specs be good for 2 aa 12" havocs as well? I read somewhere that they need 1.5 /2.5 per woofer, this would be right in the middle. 04trailblazer XS d3400 XS xp3000 Pioneer 80prs 2 pairs of DD AW6.5 mids 2 pairs of DD AT28 tweeters DD SS4A DD M1D DD 3518sc in custom kerf port box 2 runs Tspec 0/1 wire Link to comment Share on other sites More sharing options...
plush4318 Posted December 3, 2015 Author Report Share Posted December 3, 2015 how much port area/length did this spec end up having? I'm just trying to find out if I'll be able to use this box with the next two subwoofers I plan on getting. DD's website says 2 12's at 4^ft need a port area of 64.0 sq" vent x 19" long The displacement on the ts3512 is .13 cu ft. I can't seem to find any information on the displacement of the sw7200's 04trailblazer XS d3400 XS xp3000 Pioneer 80prs 2 pairs of DD AW6.5 mids 2 pairs of DD AT28 tweeters DD SS4A DD M1D DD 3518sc in custom kerf port box 2 runs Tspec 0/1 wire Link to comment Share on other sites More sharing options...
Joe X Posted December 4, 2015 Report Share Posted December 4, 2015 Different subs have different needs and can be setup for different applications, the box above will be ok for the 7200s, the havoc will need stiffer box and greater port area, the DDs, well there are many different, their table gives largest port area, entry level DDs may not need that much, also DD tunes high for loudness, one may agree or not with their suggestions depending on the application, the above box has 54 square inches of port area and will be ok for lower power subs but not enough for high output subs, driver displacement was estimated at 0.14 since there is no data for them, a small difference will not have a substantial effect in performance so you shouldn't be concerned.
