Pics new dual AE TDM10, Jabo horn and Beyma TPL150

[atilsley]

Baffles glued in today...that was a special milestone in this lengthy project.

 

[atilsley]

Testing horn mounts. These fit nicely, so I think we'll machine them in stainless steel. They will then sit into a recessed plinth, which sits on top of the tweeter housing.

Pure silver ribbon speaker cables being made, plus horn tube stained. Xovers done. Finishing off horn tube mount, then fit bass drivers, then add MiniDSP, then test.

really nice construction !!
Im looking to do a curved CNC 15in at the moment too.
I have started with the 3d modelling

 

[Best Hi End]

I'd love to know where did you get the WBT speaker terminal plates and the pure silver wire ? 50m"m speaker walls -isn't it too much ? (I thought 25 m"m of birch plywood should be satisfactory)

Silver ribbon cables and the cabinet thickness is your question?

It's a cost-no-object setup, thick cab walls leaves nothing to question, even if they're unnecessary.

Great build you have going on there
I’d love to see in more detail about the horn build. Where did you get the horn and how did you come up with the size of the rear chamber and how is the driver installed
I’m here in Florida and live horns. Most of my speakers are Klipsch and I use a few low watt tube amps and I want to build some mid and mid/horns
Thanks. And great work

Hi

The flat ribbon silver wire is 99.9% pure, and is sourced from AE Metals, here in Australia.

A&E Metals Pty Limited - Silver and Precious Metal Alloy Manufacturer - Jewellery Supplies

The terminal plates are from Parts Express, Dayton brand...which support WBT terminals.

Thank you for your kind comments.

There’s nothing too complex about the horn.

The actual horn is Jabo 350Hz KH-53 model from Germany, with 2 inch throat.

JABO KH-53 A - ART OF SOUND - Hornlautsprecher

Nice build quality…and I ordered extra sheen/sparkle white paint….looks silvery.

The horn housing is CNC’d birch ply rings.

The horn is held in place using an inner wood ring cut in half, then “wrapped” around the horn near the throat. Screw hold in place.

When horn inserted into housing, then I add 4 counter-sunk screws from the side into the “inner wood ring.”

50mm wall thickness was chosen to ensure the best bass tightness/no cabinet resonance.

I also added lead sheeting and bitumen paint.

The bass cabinets weight approx. 80Kgs each.

There are two integrated horizontal braces.

The front baffle is double walled birch ply, = 48mm thick.

I've seen you do quite a bit of stacked ply and they come up great. I've always had issues with the layers sliding when you clamp them and having to sand a fair bit, do you have this issue? Also what dowel size and hole size cut into the ply do you use?

 

[Best Hi End]

No disrespect meant,on the contrary-beautiful piece of art.My only question was in regard to where can I get these wbt speaker terminal and the pure silver wire....

Thank you for your kind remarks.

I always use dowels, typically 10mm.

See pics of other projects where dowels are critical.

No disrespect taken.

Parts Express is a great supplier.

With this project, there are 16 individual pieces of WBT gold terminals....so getting pricey. But, it's a top flight product.

Another beautiful build, as always. Congrats!

Hi atilsley,

can you provide some details about the horn in the third picture in post 33?

Kindest regards,

That is a Tannoy GRF Corner Horn.

Here's a temporary set up pic of the two way, which was the original design before we opted to add the tweeters. I really like this simple design.

 

[atilsley]

Getting close now. Wheels added for temporary transportation.

AE drivers to arrive soon (been slow).

Overall height 170cm (67 inches).

 

[atilsley]

Plinth and horn stand now complete. All wood work is finished.

Next, fit AE driver (on very slow back order), then tune Minidsp for bass.
