Trohet Speaker build

[Peter_JS]

I have recently completed building some speakers designed by Atlas from The Speaker Project.

The speakers called Trohet are their high end speaker kit.

The kit is availability with all speaker components including cabinet panels that are CNC cut ready for glue up & if required all tools needed.

I decided to build my own cabinets so I ordered the speakers & crossover components only.

Fully detailed working drawings were supplied to build the cabinets &

assembly videos were available online & were very easy to follow along at my own pace.

The speakers cabinets were made from 18mm birch plywood with American walnut veneer on both faces.

I mitre cut all edges & joined with domino’s to strengthen the join.

Prior to gluing together 3mm rubber sheet was glued to all internal surfaces

to further dampen the speaker cabinet from vibrations.

After glue up I then cut the corners out 6mm x 6mm and glued in solid 6x6 American walnut.

This allowed me to add a small radius to all corners which I sanded by hand.

After sanding all over I then oiled the cabinets using Osmo Polyx to bring up the grain & they look stunning.

I used a table saw to cut all mitred edges, router with circle jig for speaker holes, & Festool domino for cutting the domino holes.

It was a lot of work to build the cabinets but well worth the effort.

Unless you have the tools & experience in woodworking, I would order the kits with pre cut panels rather than build your own.

Cross overs had to be assembled and soldered together.

It was then a matter of gluing in the crossovers, filling with acoustic insulation & finally assembling the speakers.

I thoroughly enjoyed building the Trohets and Atlas was very helpful available if I had any questions.

Very nice job, Peter. I've used the same drivers, they look like the SS 15W8530KO mid woofer and a Vifa XT25 tweeter, in several builds over the last 15 years or so and they are excellent drivers, particularly the Scan Speak mid woofer.

 

My 2 way standmounts I built for my second system use the same drivers, however, mine are sealed enclosures, not bass reflex like yours. See pics below.

 

Cheers,

 

Keith

Thanks Keith, yes they are the same drivers. I am very happy with the sound & good bass.

Did you design your speakers?

Thanks, Peter, the original design many years ago was John Krutke's ZD5, but I modified them over the years to arrive at what they are now. These are around 7 - 8 years old now, but they have been the bench mark for what I want a loudspeaker to sound like.

 

Cheers,

You've got some serious skills for being a woodworking amateur! I've been contemplating on getting one of these kits for ages and but the bullet and got the Trohet's with the Oak cabinet material.

 

Question, did you apply contact adhesive to glue down the rubber? Do you think it's a worthwhile step?

[Peter_JS]

Yes I used contact adhesive to glue the rubber sheets on prior to gluing up the cabinets.
I think it was worth the effort to apply.

Good luck with the build.
