    I'm being serious - I can help you design a sculptured grille that could be unique for your speaker design and give it a "signature" similiar to what was done for the L100 and others.

    But no problem, if you're not interested.

    Nothing a quick suck with the Hoover won't cure. BTDT. Well, actually my kids never did that (now 23, 20, and 15) but I did acquire several with that flaw.

    These have not been polished yet. I need to let them cure for a few weeks before I do that.
    WW, those are unbelievably beautiful. Truly an inspiration. Fantastic work.

    I am curious. Did you use a binding agent with the glass beads (such as epoxy or fiberglass resin) or are they simply in the kerf cuts loose and capped with wood filler? I had planned on build something eerily similar, but planned on simply using bondo to fill the kerf cuts. Do you believe there to be an advantage?

    They are loose, well as loose as can be considering they are finer than sand and in an enclosed space. I got the idea after building an isolation dampening sandbox for my turntable at the time. They glass beads absorb mechanical energy; i.e. dampening the cabinet. The cabinets are very dead.

    Not to hijack this thread showcasing such beautiful work, but...

    If you use a single sheet of kerfed material and fill it with bondo you may be successful, as that would be a fairly low mass side that could be easily damped with a coating or sheeting. For anyone seriously considering following this construction approach, I'd strongly recommend reading through this long thread that describes my tackling the resonance issues with these cabinets.

    There was no final answer, but many methods suggested, attempted, and tried. Some things worked better than others. I certainly learned a lot from the ordeal, but I admit the results made me gun shy about ever using kerfed MDF as a speaker building medium.

    If you want to slog through the 10 pages of posts about damping materials, filling the kerfs with glass beads etc. follow the cabinets link. I posted them in the Project May private forums as the process was also being considered for that project. If you do not have access to Project May, send me a PM and I'll set you up.

    FWIW: Project May is still progressing... slowly to be sure, but it has been progressing as various members have had the time available to add to the project. Rather than tease people with the minute progress, the posts haven't been forth coming, but perhaps 2010 will be the year of Project May.

    Here is a link to an outfit on the other side of the pond ( Anaheim ) that do a huge selection of preformed curved panels. Prices do not seem thay scary to me ,but then we pay £1.15 litre for gas.

    Beautiful build on those speakers

    Hey, Ward,

    Simply stunning work, Sir!! I don't remember ever seeing anything quite that lovely, back when I was in Odessa, my hometown!! 'Course, that was a very long time ago.... Your work is exceptional, Sir, and your having shared it with us, is a wonderful thing, indeed! Thanks, very much! Take care, and God Bless!

    Every Good Wish,
    Doc

    My wife said she wants the full grills cut down so the big horn is showing. Sounds like a neat look. What do you guys think about a 3/4 grill?



    These have not been polished yet. I need to let them cure for a few weeks before I do that.

    Simply stunning, as for the grills, I can't decide. Both are great.

    Yeppers. A fella could, say, get a half cylendar http://www.aitwood.com/StoreFront.Asp?ItemID=6200&wdesc=Half%20Cylinders% 20(180%20degrees), and some of these http://www.aitwood.com/StoreFront.Asp?ItemID=8600&wdesc=MDF%20Prefit%20(L )%20Quarter%20Rounds

    and use them to make a cab that's all rounded but can be coupled to a flat face. Only problem is that you need to create a shape like a trapezoid laid on a semicircle, if you wish to do shelf bracing...... had to go with CNC work for that step.

    Nice to have these guys so close, it's a 15 minute ride to their warehouse. Hopefully I can get the baffles done and have these running by Xmas. Enclosed volume is slightly shy of 5 ft ^3, which is pretty good for most 15"s tuned to 35-40 or, a relatively high sensitivity/wide bandwidth sub with a 123A/123A-3/2213. I'll be testing a variety of drivers, the JBLs are 2226H and 2213.

    Great work.
    When you listen "serious" music go without grills.
    Stay with them only for "protection".
    Your speakers complete the living room colour.
    Congratulations.
