What is the correct way to mount the tweeter in the enclosure?
Is the tweeter mounted on the waveguide and then on the enclusure or they are mounted separately?

Thanks.

Do not mount separately. Mount the tweeter to the waveguide and then mount it, waveguide and tweeter together, as a single unit into the enclosure.

Correct. You will need to make recesses for the nuts holding the wave guides to the speakers

Default Update on Construction

Making great progress over the past couple of weekends. Enclosures are taking shape and soon should in the prep stage prior to applying finish (paint, though thinking about veneer at this stage).

As one might see, using biscuit jointery to assemble the butt joints, except for the main brace where it is a bit more difficult to use the jointer, so just screwed and glued in place from the inside to avoid having to patch external screw holes. Also trying to avoid splitting MDF. I still have a little misalignment of the baffle to the side panels, the baffle is perhaps 0.2-0.3mm or so beyond the edge of the side panels (an artifact of the slop between the jointer in the vertical vs horizontal orientation when cutting the slots for the biscuits). If it was the other way it would be easier (planing/sanding down the edge) however now I need to patch and built back up the panel edge. Bondo time.

Used a neat T-nut insert designed for hardwoods for the driver mounting holes. These have short anti-rotation barbs on the barrel of the T-nut rather than spikes on the flange. Drilled out the holes to the barrel diameter, applied a bit of glue (slow setting Superglue cement) on the T-nut flange and drove them home. No splits. These do not need as large of a hole than other nut inserts, and are steel rather than zinc or brass.

Looks like they are coming together nicely.

I hope a locals listening session is part of your plan!

Default More Progress

I had a little time yesterday, so glued the top and bottom on the enclosures. I made clamp extenders out of scrap MDF which were very helpful in gluing the ends on. Also, I added the damping insulation in the back corners at this time, since I figure it is easier to install with the enclosure still open. Used 1" thick bonded Dacron batting that is normally used for upholstery. It was sold as 1-1/2 to 2" thick, but the thickness was actually slightly over 1". Will see how it works.
