Hi!
Can you tell me more about the construction details? A friend will try a similar design with 2 pairs of alpair 7.3.
Kind regards,
Douglas

Chr70.2 Microtower. I am very happy with these. I used a water based stain and varnish that went on to the birch ply much better than I expected.

See this thread for details. microTower bipolar ML-TL for CHR-70 or EL70
I used birch ply and pretty much just followed the plans. I use these speakers everyday.

My recently crafted Welsh slate full range speakers with Manger® sound transducer
Made with a visco-elastic bitumen core sandwiched between two layers of slate followed by polyurethane foam, pure sheep wool and Mundorf® unicorn tail wadding. Before application of the composite layers the stone has a ring but following application the enclosure becomes extremely damped, so much so that by pressing your ear against the side of the enclosure while playing music at high volumes you will notice a very quiet, distant muffled sound that is barely audible over the sound coming from the front of the speaker.
The Enclosure volume has a shape designed to funnel the internally radiated sound to its rear tip where it is dispersed by the Mundorf® Twaron Unicorn Tail wadding and pure sheep wool. The Twaron fibres run in a fine layer above the sheep wool from the front to the back inner point, further focusing the sound along their length to the dispersing back point of the enclosure. There are no internal parallel surfaces to prevent standing waves.
By utilising the MANGER® sound transducer the dolmens are able to achieve an incredible 80Hz to 40,000Hz frequency response with a blisteringly fast 13µs rise time. The active surface of the MANGER® sound transducers flexible diaphragm becomes smaller as the frequency increases so that the effective surface is always kept small in comparison to the wavelength to be radiated.

Unfortunately Daniella Manger stopped raw sales of the Manger sound transducer to both DIY and OEM 4 years ago.
very unique drivers with a silky smooth sound.

Yepp!
Forgot to mention. It's an oval 6 by 9, SWR069A (A=AlNiCo), fullrange driver from Hungarian Sonido.

Hi Steve - How are the Fanes holding up over the long haul?
I've got a pair on the way and plan to try them in a pair of JE Labs OBs I've got that take 12" drivers.
Has anyone else tried the Fane Sovereign 12-250 TC in an OB?
Hi
See micro tower article here :
Frugal-phile | Box Library / Mark Audio
And list details you want to know
