    one day....
    Anyone try it? i saw an amp company called Visual...something and what clearly looked like a cheesy hubcap as speaker grille.

    Well i have a 1999 subaru outback sport, and as I have been missing 2 hubcaps for several months I got some 20$ ones from amazon (A subaru hubcap costs 100 for some reason. plastic. I could get a nice alloy wheel for that!)

    And I put them on, I had just gotten some very nice Cooper tires (merry Christmas, Thanks Mom!), they fit fine. When I got home, surprise, one was gone. The worst part for me was I had bought some 60 second epoxy wit the intention of just gluing the hubcaps on with spot welds in a couple places, so i could pop them off again, but would hold better than the metal ring thing alone....but i misplaced the glue.

    Back on topic, I think there are some hubcaps that would look pretty cool as speaker covers. cgood2.jpg cgoof.jpg cass.jpg

    It's not a "hubcap", it's a "sound dispersion speaker grill". :rolleyes:

    ...joking aside, it really is: The design consists of a sound dispersion cone and center high-frequency blocking hub. The spokes helding this on place are specially tapered to block as least as possible. It's designed to be a dispersion grille but it coincidentally ends up looking like a hubcap, a feature which was deliberately exploited by the designer.

    I would reckon that an actual hubcap wouldn't really perform as great as dispersion grille as dispersion grille would perform as a hubcap. That is to say, don't confuse them with each other.

    Looks super cool! I'm partial to the pignose style guy for amps I don't move around too much.

    What's the best hubcap for metal?

  10. Let's see.

    One: I mount small bass combo on each wheel of my car...
    Two: reattach hubcap.

    Wait, my headstock sticks out the window....

    At 60mph it gets chilly in the NE.

    I suddenly have the urge to mount hubcap spinners on all my amps.

  12. Didn't BFM use a reflective hubcap in one of his designs?

    Plus the home wound double coil subwoofer, this is definitely going to be a one of a kind rig!

    It could work really good. The center cap would work like a phase plug, like the ones BFM has in the Jack and Otop cabs. He wouldn't use them if they didn't work.

    I was thinking this, also.
    Plus, it may produce a cool Doppler Effect!:p

    High frequency beam blockers are nothing new, so why not give it a shot. Some companies mounted their speakers behind the baffle and had a cross member in the baffle that did something similar.

    Your can read about how they work and see the product that Weber sells here:

    ...and you can read about how they don't work and how to make something that does here: Speaker Directivity Modifier

    Edit: I have tried this and can't say I've really noticed much difference. It was easy enough to do though.

    for a front mount speaker, could you just cover the entire baffle with the foam?
    Seems like i've seen that before.
    Didn't the polytone amps have foam covering the front of the baffle behind the screen?

    The Visual Sound "hubcap" actually combines "waveguide" concept, similar to this old Teisco Checkmate amp, with the aforementioned "beam blocker" concept, which simply puts an obstruction in front of center parts of the cone diagphgram and therefore modifies dispersion characteristics so that higher frequencies disperse to less narrow area than without the waveguide/beam blocker.


    So, it's not a hubcap, it's specially designed dispersion modifier grill that is just deliberately made to look like a hubcap - because it can. That in mind, you can't just slap a random -real- hubcap in front of the speaker and expect it to perform similarly.
