fiberglass enclosure flexing some ?

[mattmcss 10+ year member]

my box flexes a little bit , its really stiff you have to really push on it to tget it to flex , i know i will lose output because of this , however , how much will i lose ? If i decide to slap some bondo over it to smooth out the rough parts before i cover it with carpet , will the bondo crack once its all hardened up if the box does flex ?

Should i keep doing glassing until there is NO flex at all ?

how many layers do you have? if its flexing, i'd try and add a couple more layers

Or add a few 1" long strips of mdf to the insides. Space them out evenly, you would only need 2-3 on an average sized box. These can be glassed in no problem. However, perhaps you need to add a few more layers.

My new kicks have the same problem. You will want to take care of it quick. Mine resonate at like 90hz because I only did one layer of fg cloth over the sides. It makes for an annoying hum.

MORE GLASS! You DEFINITLY dont want ANY flex, you will lose out on alot of SQ and output.

Tomorrow I start on my *second* set of kicks, and I might work some more on my first and put them in my bro's car, since he has the exact same model.
