Joe X Posted May 12, 2014 Report Posted May 12, 2014 What is a dd-1 ? It's an easy to use device that helps you setting your gains properly, it can save your subs from cooking due to amp clipping, if you don't/can't want to buy one, someone on this forum living near you who owns the DD-1 can help you setting your gains with the device. So that you know what is it here's a link: http://www.wccaraudio.com/front-page-categories/most-popular-products/smd-distortion-detector-dd-1.html I just want to forward you some infos before you get into building your box.
irnlve Posted May 12, 2014 Author Report Posted May 12, 2014 Ya I have a friend n town here that competes and goes to world, I believe he has one..
Joe X Posted May 13, 2014 Report Posted May 13, 2014 So this is just a sample design for a dual tuning box, I have set a low tuning of 34Hz with one pipe plugged or 40Hz with all pipes open, optionally you can build a removable port for the box so that you can tune to other frequencies. TO NOTE, this is not a spl box since those are setup with a termlab and the parameters of the box are changed at test time. Your amp subsonic filter should be set no more than 5 Hz below tuning during the tests or thermal/mechanical failure of subs may occur. Also if you don't have proper power and gains properly set thermal/mechanical failure or amp damage can occur so be advised. Minimum port clearance = 4" Removable port module version:
