  • The Big Bonehead Array

    Getting ready to pull the trigger on my order for my 3rd generation garage speakers:

    Design parameters
    1) Loud
    2) mm... that's about it.

    Design
    8' tall line array with:
    16~5" Buyout Concave Paper Cone Woofers (per side)

    http://www.parts-express.com/pe/show...number=299-289

    32~Jamo 20132 Paper Cone Tweeters (per side)

    http://www.parts-express.com/pe/show...number=299-965

    Boxes will be sealed, 3.5 cu-ft with an f3 about 90 hz. Ample bass boost is planned (until dream garage subs are built)

    Amplification/crossover
    I have 3 beater 100wpc integrated amplifiers. I will subdivide woofer section into two chambers and wire for 4-ohms each. Plan on electronic cross-over. 2-amps for woofer sections, 1-amp on tweeter section.

    Please, don't take this build too seriously. This is all about having fun breaking eardrums, not esoteric audiophile perfection. Below is a rendering of my design (to scale). Progress updates to follow.

    That's pretty ******. You should look into a MiniDSP for 125 you can use it with REW to get a flatline response.

      Dude, forget the beer bottle. Make a combo recliner/sub/keg cooler.

        Well it looks to me like it could be a lot of fun and a pretty cool set of party speakers. The beer will definitely help with the fun, and maybe the SQ. :D
        BTW, where are you? I'll bring the beer if you're near Bismarck!
        Have fun!

          I was thinking much the same thing....your 'beer to scale' rendering is short by about five.

              OK - parts ordered. I guess it's time to buy some wood.

              And based on some of your suggestions, I've made a few revisions to the design. I think this will more accurately model how these will perform, once complete.

                        I would like to know what you think of those tweeters once you get to try them out .

                        Push the Vb up {6cuft there about} , with the room you might find you got all the low end you need .

                              Playing with box alignments:

                              Yellow - my original 3.5 cf sealed box. f3 about 90hz.
                              Magenta - cranked up volume to 6 cf as suggested...not much benefit.
                              Green - 3.5 cf ported (tuned to 60 hz) f3 about 55 hz (mo betta)
                              Cyan - box split into two (1.75 cf) - same response as green.

                              I'm going ported. If/when I build a big SW and/or power handling ends up being a problem, I'll just block off the ports.
