Here are some pictures of my solid cherry & walnut MTM build.
You are not supposed to build a speaker out of solid wood because of crossgrain wood movement.
All the wood grain in this speaker goes the same way.
Drivers are a pair of custom Seas 6-1/2″ L18RNX/P based Prestige 4Ω Woofers and a Morel Morel MDT-40 1-1/8" Compact Dome Tweeter.
Crossover is at 1900Hz.

Yeah more pics, brilliant job, great detail and accuracy.
Just one question, what would you charge to build these for fellow members ?

Amazing! More pics of the wood finishing, please! What did you use there? Danish oil or something similar?
That is stunningly beautiful. I can't even imagine the craftsmanship and skills
required to do something like that.
More pics when you have them please. 🙂

For a finish I use a 1:1:1 mix of satin oil based polyurethane:boiled linseed oil:turpentine. Brush on, leave for 30 min to an hour depending on heat and humidity, wipe off. Speakers got two coats inside, three coats outside. This is a finish for dummies. Super easy to do. Just make sure you dispose of the rags correctly by burning them or hanging them to dry, otherwise they could self combust (I am serious about this!).
Are those real measurements? If so, how did you make them? What kind of room? What microphone did you use?
Hello,
Yes, those are all real measurements. I used a UMIK-1 and REW for the measurements.
They were all taken at about 25" on axis to the tweeter.
For crossover purposes the woofer was also measured at 1/4" and merged with the 25" measurement, baffle step compensation was added with,
FRD Blender and Minimum Phase Extractor
My living room, which is a good size room.

This is what happens when a craftsman builds speakers 😀 Not only will audiophiles admire your speakers, but others' furniture will envy it as well 😀
Interesting. I would have expected a much less flat response when taking the measurements in a normal room but perhaps that's the applied smoothing.
Well done!
