    Fabulous Rick!!! When you told me you were going to get your pics up, I had no idea how beautiful these speakers were. Nicely understated in black baffle, maybe an additional highlight with an 077 instead of a 2405?

    Those wooden lenses look great. Wasn't someone else on the forum trying to produce something like that too? Seems to me a pattern and a set of supports could get the ball rolling for reproductions of that.

    Great work as always, very inspirational. Now just gotta clear enough garage space to have the right woodworking tools.

    Regards,

    Cool In black...amazing.

    That, sir, is the most beautiful thing I have seen in all of these DIY projects to date. The black really classes up an already classy monitor. I have always admired the look of an L100 baffle, but never imagined a big black baffled 4way. Spectacular.

    My question is- how on earth did you do it. It looks simple enough, but I gather it isn't. Seperating the veneers and finishes- must have been a mighty chore.

    BTW, did you reinforced the timber in that room- that's a heap of power!!

    Black Baffles

    Thanks for the compliments guys. The black baffle is something I wanted to do since I first had a look at Black Ash Veneer. Incorporating it into the design of the monitors likely increased my invested time by 50% so it's not something I'm going to do too often and not without a serious arm twisting if I do.

    The baffle is veneered before all of the holes are cut. Since the 4345 has mirror imaged baffles, I placed them face to face and cut all holes in both baffles at the same time. The veneer was protected and there are no ragged veneer edges when complete - unless the 3 1/2hp router gets out of hand. Makes you pay real close attention to what you're doing. I don't allow anyone in the shop when I'm doing this kind of work.

    First thing I do after cutting all of the holes is spray about 3-4 coats of laquer over the veneer to seal the grain. There's a lot of forgiveness when building a monitor that will have a painted blue baffle - but with veneer once it's glued into the cabinet you must live with any mistakes, any glue that seeps from the joints and any dings you put in the finish. I keep the baffles covered with plastic sheet until the cabinet is assembled, sanded and oiled. After that I remove the plastic, dust off the surface with 0000 steel wool and apply 2-3 more coats of laquer. If I always remember the risk I figure they will come out OK.

    The chore wasn't that painful but did increase my overall construction time by a significant amount. Having said that, I recently decided to provide a home for a set of 4315B components that have been sitting in storage for near 6 years. Their home will be a pair of white oak 4315 cabinets with burgundy grille cloth and mirror imaged black ash baffles. The cabinet parts are already cut so I just need to find some time to build them. I figure they should look good enough that I can slide them into the wife's living room. We'll see!
