Dayum!

Very nice build! I bet they sound fantastic.

I spent quite a while trying to figure out how to do a curved grill to match the profile of the M2 waveguide. After a little measuring I cut an arc with a radius 4' 9" and it looked about right. Glued up some scrap 1/4" plywood and came up with a grill frame. I used perforated metal from McMaster-Carr (# 92725T22 Hexagon-Hole Perforated Sheet, .030" Thickness, 22 Gauge Steel, .25" Diameter, 79% Open Area, 36" X40") to attach to the grill frame to form the curved profile for the fabric. This material is rather thin and light duty - it will serve the purpose but will provide minimal protection from rowdy drunks and children.

I used 2-part epoxy to secure the grill to the frame and then used body filler (Bondo) to smooth everything up. Lots of sanding followed by a healthy does of flat black spray paint. I used basic black grill cloth and followed Saeman's Zilch Cloth Installation method (http://www.audioheritage.org/vbullet...h-Installation). No need to show how sloppy my attempt turned out. Neo magnets were previously installed in the baffle and matching neo magnets went in the grill frames. Note - pay attention to polarity.

The clones were not in the living room for a day before photos, knick-knaks and plant appeared on them. I also found myself setting beers and tools (always plural and always together?) on top of them....they are a perfect height. So I ordered some smoked glass tops from the local glass shop....1/4" thick, tempered, with beveled edges. Measuring and calling in the order was the easiest part of the project so far

Thanks guys! I could not have done it without help and advice of the Lansing Heritage crew.

Wow!
It reminds me of Widget's drawings: http://www.audioheritage.org/vbullet...l=1#post379478

Nothing short of brilliant!

Those are really good looking and I actually prefer them to the originals withthe front covering the ports.

Congrats to a pair of very fancy looking M2’s

Hello

448mm x 394mm

I will measure the depth(s) tonight.

[Doctor_Electron]

YES !

Outstanding.

I have three questions.

First, what music do you listen to with them?

Second, (and I know this is a tough one) do you have a number as to the completed weight of each? I'm thinking you would have had to measure components, parts, subassemblies etc. prior to final assembly.

Third, would you mind posting details about your listening experiences, regarding the systems' sonics, imaging/soundstage in that room, and the qualities of their rendering of the media (as in Q.#1) ?

Thanks, -d. E.
