Another 3 weeks or so and I might have the other one built, and then I can think of finishing!
Yes, I know it's MDF, but I was finding Baltic a challenge to source, and in the end used the maxim of better te poorer choice than nothing at all!

Nice one Dave. My test boxes are also MDF, for much the same reason (as well as cost). Glad you like it so far...

Some pictures of the cabinets now I've figured out how to extract them from the camera.

For reference, the finish on the sides, top and rear is 3 layers of B&Q own brand 'Sable', an oatmeal coloured satin paint, applied with a small roller over MDF primer. The front baffle is sprayed in textured, stone effect platicoat, and the inside of the horn mouths are pained sable, applied with roller and brush, with a thin layer of the stone finish over the top.

This last actually looks better in natural, constant light conditions than it appears in the pictures -these were taken at 7.30pm yesterday, when the light was nearly gone and the flash didn't do them any favours. In daylight, or under a lightbulb etc., the finish on the horn mouths appears much more even.

I decided not to include the mouth braces after first listening to them 10 days ago -despite the MDF, they didn't appear to need it. A little vibration, but not much -in a good 3/4in ply, I can't see anyone worrying.

Another angle. I'll give their plinths a quick slap of paint at some point soon as they're not too pretty.

The proportions of these things are stunning, if I do say so myself... (even if I'm hardly the greatest builder on the planet). And they sound fantastic too. Which is nice. BIG sound, but so precise.

Greets!

Correctomundo! 'Pancaked' against a wall firing into the corners turns the whole end of the room into a subbass horn and you could 'pancake' stereo BLHs to the front of it to cover the rest of the BW.

Greets!

I was thinking more in terms of a split fold with mouths on both horizontal sides to load both corners........

Ah, ok, have tried to draw a pure cornerhorn, no luck yet

Have remodelled and hopefully refined the one Dave liked

Actually it was Scott that inspired me, as he requested a bit more length without too much bends

Imagine to make those frugel-cutouts...gets veery sculptural
