Quiet4Lyfe Posted April 19, 2015 Report Share Posted April 19, 2015 Hey guys! We recently tore down our 4th order in the Expedition, 4 zv.4 18's on ab750.1 for an attempt at a 6th order!! This is our first attempt ever at a 6th order in general so might as well share our mistakes and progress with you fellow bass heads! Our 4th order managed a 151.2 sealed on dash, we are hoping for 153 with this build! Bandwidth estimated, 18-55 htz! Stay tuned! Will update over time, (not working on it every day)! Time to drop 500 bucks on wood. Ill take em all! LIL MAN PUTTIN IN WORK! Just a bunch of beginners building a wall nothin out of the ordinary Ran into a space issue with the 45 degree angles.. Decided to go with the Corners to add space. Here at beginner central, We like to complicate things as much as possible. Well, in a sense save some time! lets cut through all the baffles at once! YEAH! MERICA! Thanks for tuning in, Current progress after 2 days of work, Top, corners, sides, bottom, and one baffle is in! more progress to come! Any and all criticism and/or comments welcome! BASSHEADS! It's about to get QUIET. Expedition, Quad zv.4 18's, ab750.1, quiet mode activated...

420c Posted April 19, 2015 Report Share Posted April 19, 2015 How did you choose the rear box volume for your subs? Link to comment Share on other sites More sharing options...
Quiet4Lyfe Posted April 19, 2015 Author Report Share Posted April 19, 2015 The rear chamber is 25.4 cubic feet, 156sqin port area, tuned to 28. Front chamber is 33 cubic feet, 780sqin port area, tuned to 48. So expected bandwidth would be around 17-55 htz. It's about to get QUIET. Expedition, Quad zv.4 18's, ab750.1, quiet mode activated...

Front chamber is 33 cubic feet, 780sqin port area, tuned to 48. So expected bandwidth would be around 17-55 htz. From what I've been told you want to tune a full octave apart if possible. So 28 and 54... just what ive been told. Other than that I like the specs Link to comment Share on other sites More sharing options...

db_speakerbox Posted April 20, 2015 Report Share Posted April 20, 2015 Nice start. $500 for 10 sheets of mdf are you kidding me? I would have thought being in WA wood would be cheap. It's like $35/sheet here in KY. I would recommend a router and spiral upcut bit with a circle jig. Much easier and faster than drilling a 1000 holes lol. You can pick up some entry level equipment pretty cheap and build a bit collection over time. You would be amazed all the cool stuff you can do with a router and the results you can get with little time or effort. Link to comment Share on other sites More sharing options...

My 6th is tuned to 28 and 43 and is within 1db from 33-46 and plays 18-50 2006 Ford Explorer 2 Team AA/Sundown 15s 6th order Ct Sounds 7k 4 PRV Mr500 8s Rockford p1000-2 Team Subsonic Lows Link to comment Share on other sites More sharing options...

Larger the ratio the larger the peaks will be Link to comment Share on other sites More sharing options...
