Yes, the front corners are done with solid Tasmanian Oak quarter round. Supra-baffle is Meranti, round-over or crown done with a 4" angle grinder with 60 grit. 12 coats of regular varnish top coated with Cabot's satin poly varnish from a spray can. I don't like shinny.

MDF has many coats of interior water based paint, sanded flat with 320 and waxed with floor wax.

It seems that I can play them louder without them sounding loud. Less bass than the BIBs. The "Sweet spot" is larger. Drivers had about 200 hours of break-in before install.

Cheers, Mack

Did you like the sound more with BSC? Any of my SE tube amps (300B, 6EM7) would dive either speaker to good volume.

I hope you are using tube amps with these speakers.

Beautiful builds. The time they took seems to be well spent. The environment is beautiful too. That wooden sculpture by the table seems very nice. Is that the usual listening place? They seem to be very far away from the walls.

The sound is everything I need.
Working some other versions for home cinema set up.

At the moment got 32 drivers for stereo... going to have close to 60 drivers in the home cinema rig!

Hi O.A.

First might I ask if you're the guy who built those awesome speakers with the Manger driver on top and I believe an 18" JBL below?

Your speakers sort of remind me of my friend Roger Russell's IDS-25 speakers which used 25 3.5" drivers per channel! But I digress, I hope you'll be telling us a little bit more about your speakers, hummm? While I find the idea of having 32 drivers for stereo ---{I'm assuming you mean 16 drivers per channel}--- the type of driver itself would be quite critical in how the end product sounds, no? So how about sharing which drivers you're using? Inquiring minds want to know!

Thanks!

RK1, the grill is heavily bevelled inside and out and sits on top of the driver frame. It acts like a short waveguide.
