    Default Metal Speaker Grill


    I got a request from a pet owner to come up with a decorative metal grill to protect their speakers. I think this is an "I'll know it when I see it" deal but my interpretation is they want a raised rectangular barrier that is acoustically transparent and that won't vibrate esp. on a subwoofer.

    Unfortunately, most of what I found would cost more than the speakers to build (architectural metal, cut with plasma torches, etc.) The only cheap products I found were the round wire-mesh types or the hub-cap looking stuff typically for auto applications.

    Does anyone have DIY or commercial speaker pictures or sources for such an item. The only commercial designs I have found so far are the stretched wire types that Nohr and Sonus Faber use.

    (Also, please spare me any OT advice on how to torture pets or small children in the name of sonic purity.)

    Thanks in advance,
    Murray

    Perforated metal (like the kind found on catwalks and certain picnic tables etc) is easy to cut and weld, cheap, and would definately deter small animals.

    Unfortunately, the chances of it being acoustically transparent is pretty much nil.

    The hexagon stuff is 80% open area, and in aluminum could be an attractive custom grill.

    Try TCH. They offer black powder-coated perforated grille material in several thicknesses & hole geometries.

    I've done extensive "critical listening" with & without the grille. Seems to have little effect on HF perfomance. LF is about the same, give or take.

    PE has a whole line of round, metal, perforated grilles for various driver sizes as well as specific mounting hardware. Just type in "grill" in the upper Search box on their home page.
