    Okay, this is more of a fun project than a project that will get use of. Nonetheless I have an idea to build a big speaker tower containing

    2-15in woofers
    2-10in woofers
    2-8in woofers
    4-5.25 components
    2-big horn tweeters

    I already have the woofers laying around the place so its not like the brand matters. I can replace them later if the box turns out to actually be good. This will be powered by a car RF 1000watt amp. Not sure on the model ## or anything else.

    My ? is, what do I need to make sure of when building this huge box and how much cubic space do I need for each woofer, I can do seperate chambers for each woofer if needed but the one big box idea needs to stay b/c it will be going stand up in the back of a truck bed to play loud towards people. Any website you could refer me to or anything would be great.

    Cliffs: want to build big box for speakers. where do I go to get info on building such a thing.

    in for disaster

    go buy the speaker builder handbook. Designing a crossover is probably the hardest thing to do.

    Ya...I'm pretty sure this is a much bigger project than I was expecting. I like to do a lot of research before I start a big project so I will start looking at crossovers and box size requirements. My goal is just to have a "portable" loud one piece system :)

    What kinda wood do you suggest for me to use. I was thinking maybe a 5/8 MDF, but really not sure on what makes sound the best.

    if all that is going into one structure im highly doubtful of this project

    why not do something like

    2 10s or 12s mounted on sides of cabinet
    4 6s up the front (or similar size woofer)
    single horn tweeter at top

    :dunno:

    Stupid.

    BUT...

    Yes, you will need to design a VERY complicated crossover... you will not want much overlapping of frequencies... or you will get hardcore cancellation.

    Long story short,

    I'd do a Horn, two 5.25's, two 10's, and one 15 per cabinet AT THE ABSOLUTE VERY MOST. heh.

    Okay so I have taken some advice and decided to go with, a tall tower with 1-15 1-10 1-8 2-5.25 and 1 horn tweeter. Then I will make two towers like this. It will still probably make each tower around 80lbs but thats fine if its in the back of a truck. Demolition starts in 3 weeks once I have completed the plans and research.

    Why not just get rid of the 10's all together? Have the 15 cover everything below 100hz, the 8 cover 100-400, the 5.25's cover 400-2000, and then have the tweeters cover 2000 and up.

    i bet the 5.25s could hit a hair higher than 2000, maybe im wrong though
