First cabinet arrived.
Walnut veneer with matt finish looks great and has nice tone.
Front baffle is black matt finish with fine structure so fingerprints dont leave the marks.
Black plinths will arrive later, they will have integrated wheels for easy manipulation, and together with black baffle it will optically create "L" shape.

puppet: thank you, I will tell it to my carpenter
I think it is worth showing here, so I attached photo of rear side of the baffle. It shows how baffle is sat in the cabinet. There is no gap between baffle and cabinet. I assume this took several fitting tests, adjustments, and precise work with the router. The right amount of the glue was the key and any excessive glue had to be removed at the right moment.

The transition from full radius to partial radius between the woofer and mid is difficult to do with conventional power tools. I suppose with NC it is no problem. Very nice cabinet.
It is actually quarter ellipsis profile around mid-tweeter and woofer, and this part was done by nc machine. The rest was done with router. Front baffle is laminated from several layers and openings behind mid and tweeter, T-nuts installation etc were done in the process.

Wow, I if I ever should build the "best loudspeaker in the world",
I´m gonna use that same carpenter. So beautiful. What puppet said +1.
Brilliant fit for those high quality drivers.

Looking very impressive !
Please let us know how the T34B sounds in comparison with the T25B, especially in the highest octaves.

Jeroen, thank you.
In coming months I will have a comparison of T34B and T25B in very similar waveguides, and also T25B without WG. I will report the listening experiences.

Subscribed great project - I am considering a build similar to Joachim Gerhard's ARA
Why are you using a waveguided T34B, the smaller BlieSMa T25B has excellent dispersion and probably higher output within a wider radius?
Perhaps your just using the waveguide for time alignment, rather than stepped/inclined baffle?

stretchneck: I already have experiences with T25B, measurements and listening. As it does not like crossover below 2k and shallower slopes, T34B and even with WG seemed to be better match to 7" midrange.
T25 would require either LR2 at 3k or LR4 at 2k. Both would not be optimal to get smooth off-axis response. LR4 would result in typical narrow-broad pattern around crossover point.
I also wanted to try T34 and make a project with WG as I already had it. I am also very curious to listen to mid-tweeter crossed over at around 1200Hz.
T25B strong broad directivity makes it sound very ambient and creates large soundstage, but is also more demanding to room acoustics and can sound little bit annoying after longer listening. This requires very fine tuning of 3-10kHz area and FR in that area must be pushed down 1-2dB.
Waveguided tweeters are easier to listen to, and in case of T34B+WG I think all good sonic attributes of high quality Be tweeter will be maintained and comparable to T25, yet it will be easier to listen and somehow lighter and airy in 3-10kHz area.
