clamshell improves sound quality and powrer handling.

do it.



use finished box for 4 weeks lightly stuffed with polyfill, then remove polyfill and see if you can hear the difference  :-?.


tuneng is easy, set the internal box about 2 inches from the bottom and listen to a few songs, then move the internal box back 2 inches and listen to the same few songs, then move internal box forward 5 inches (almost to the end but 1 inch) same songs.

then fix it in the position you enjoyed the music most at.


there wont be a big difference in the tuneing, but if you listen carefully you will hear a subtle and worthwhile one.

a little like a sports car, its fast no matter what, but after a 'tune' -up its performance is just a little better.

its been a while since i built mine so i dont remeber exact pannels, i just keep reading the plans until i understand them.

eventually they make sense.

and when you have decided where you want the insert,

seal everything you can with silicone, or caulk or soething, the better you seal it, the better the sound will be,

any air escapeing can cause problems. (rattling squeaking chuffing sounds)

seal everything you can get to.
