Diamant Noir : 3 way, ScanSpeak, active filtering

Here's my current project, a 3-way tall loudspeaker using ScanSpeak (double woofer 22W Discovery, medium 15M Discovery and tweeter 602010 Illuminator), amplificator Ram Audio T2408, active filtering on a HTPC using an E-MU 1820m soundcard.

Here's a 3D render, using Blender software www.blender.org :

I'm used to 3D for other purposes and using it for loudspeakers allow me to create blueprints to be used in my workshop :

Each enclosure is made of 23 panels, here are some picture of the first test assembly. Front panel and inner frames still need to be hollowed out, obviously.

Some detail on the adjustement of the panels : eache one must be cut at a different angle, to be able to assemble them. So 3D modeling is extremely useful to get accurate dimensions, which I draw on the panel to cut the angle using a belt sander.

Hello,

Here're an update after some more hours this week-end : I sanded some angles on some pieces to do a test assembly.

You can see the current state of the build on the first 3 pictures. On this side of the enclosure, I need one more triangle at the bottom, and 3 other ones on the upper end. And the top, going from front to rear end using a 4 cm wide piece.

The next two pictures show the inside : you can see the gaps between not-so-well-adjusted parts :) I obviously need to fill them with resin or wood glue.

Some frames are missing (the medium enclosure) and they still need to be hollowed.

I guess you noticed it requires masking tape to hold it in place. Completely not suitable for gluing, so I used some small metal squares. Maybe not enough for white gluing it so I will try neoprene glue.

The last two pictures show the enclosure in the listening room, standing along with my current setup : DIY bookshelves and a W12 GTi subwoofer. Looks like the right size, like a friend of mine said :)
