ScanSpeak Revelator-851, built by Robin, England

Dear Troels,

I finally finished the construction of the Revelator-851 Be a couple of months ago.  They only seemed to take a short time to run in but, unfortunately, I changed my power amp at the same time - which took a bit longer to settle down.  After a few other system tweaks they are now sounding absolutely fantastic.  I’m very pleased with the results - a massive upgrade to my previous speakers.  The only lingering issue is some bass boom as my room is small and I can’t get them far from the rear wall and sides.  I intend to follow your advice and fit HYPEX units on the bass channels to provide DSP and moderate the response spike.

For construction I followed your design exactly apart from one feature.  I wanted a Zebrano veneer finish but could not find wide, iron-on sheets - the only veneer available was pieces of real wood veneer in sizes which would require splicing .  As that was a long way above my DIY skills, I used Zebrano veneered 7mm MDF on the sides, top and lower baffle.  I reduced the thickness of the birch ply on those panels accordingly so the final thickness slightly exceeded the recommended thicknesses. As per your other designs, I used a flexible glue to bond the MDF to the ply.  Solid Zebrano was used for fillets for the side of the lower baffle and the plinth.  (The only other challenge is I couldn’t get 30mm black Valchromat fro the main baffle in anything smaller than a full 2.4x1.2m sheet, but I managed to get blue in bespoke sizes - so it just required staining and painting.)

Thank you for your design.
Best regards
Robin
