Hello Troels
Happy new year and I am glad to report to you
that I finally finished the Zahra speakers. This was supposed to be my
first speaker project back in 2007 but did not have the experience and
also time to finish them until this year. It is better late than never,
as you say. Now I know I need to choose a project carefully but I am
glad I had purchased all the parts back then. I have been listening
Zahra for a couple of days and the sound is developing very nicely. I
played them really loud today and the speakers deliver. This is a fun
set of speakers to listen to. The sound of a drum is solid and a
delicate female vocal can also be played quite well. I will continue to
listen to them and decide if any adjustment in damping or attenuation
would be needed.
I built the enclosures with Baltic birch
plywood and finished them with Australian lace wood veneer. The front
baffle is 1 inch thick African Bubinga wood. I gave them a few coats of
polyurethane and the speakers have a nice gloss now. I used 1/2 inch
thick Whispermat II for damping on inside surfaces and added 1/2 sheet
of MDM-3 in the back of the woofer section and also the top and the
bottom of the enclosure. Internal wirings are 12 and 14 gauge silver
plated copper wire with Teflon insulation. Each speaker now weights
27Kg and quite heavy. I thank you for sharing the construction project
and will play the speakers for a long time to come, I am sure. Best
regards Young.
