    building a speakerbox, question?

    hey all.. got a question..

    I'd like to make a basic rectangular box to hold 2 10" subs. I've done this out of 3/4" MDF board before and the sound was amazing (calculated the volume and everything)... My question is can I do this using lexan (plexiglass) and get the same or similar sound results? I want it to look cool yet sound good too.

    anyone done this?

    I think you'dhave to have an MDF frame becuse the plexi would flex(i). But an MDF frame,painted black, with plexi/lexan windows might work. maybe a rough idea

    Yes, 3/4 plex or lex is way stronger then MDF. Do your self a big favor and drill pilot holes trough the plexi before you run screws threw it. i did a 10,000 dollar system in a honda once and i used 3/4 plex sheet to be the front wall/face of the box, so you could see the subs when you folded the seat down. i also had the subs inverted so you could see them from the trunk too. i was using 2 eclipse titanium 12's they were getting 800w to 1000w a peace. with no problems on the plex

    ok now I went to Home Depot and they didn't have ish... where would I find some of that 3/4" plex/lex? and is it pricy? I don't want to pay outrageous $$$ (im a cheapo)..

    one more question.. what is the best adhesive for glueing 2 pieces together? I want something that holds/seals.

    GLUE!?!?! Never GLUE anything, What and why do you want to glue.
    the peace i had was about 3'x2' it was about $60.
    Look for a plastics or glass place in the phone book call around and some pne will point to the right phone number.
