bass boxes

[Clio Boy]

i am building by own bass box at the moment for a 12" sub. Is it important to line the box with foam or not as opinions seem to differ. any help would be appreciated.

[epo]

i went round all the joins of my box with silicon i put fuckin loads of the stuff on it

i put wall cracker filler in mine lol u cud tell the difference it makes cos i put 2 subs in one box and made a divider in the middle n i hadnt put filler round the edges of the divider n i cud feel the air comin thru wen i had just one sub in place. :lol:

The gaps need sealing to make it air tight but other than that, no foam is needed. however if u want to simulate a slightly bigger box, to give lower but slower bass, fill the box with loft insulation. u can experiment with different amounts to get a sound u like that works with the music u like.

i fuckin hate loft insulation always have 2 run cables up in lofts and the stuff itches like a bastard :lol:

wil bear that in mind and not use loft insulation then. ta

u can buy special dampening foam just for it it costs bout 3 quid per metre depending on thickness.
