I had a pair of Rauna Tyr II speakers that were made in Sweden. The Cabinets were solid Concrete. Not as Porus as Cinder Blocks. And they were also 86 db.
Manufactured in the late 1970s - Early 80s..... The were Monitors about 14 inches high... They were 'Killer'.... Nothing I could find could touch them. I had compared plenty Monitor Speakers (All of the Known Contenders) in my home that Cost around $5 Grand and none of them could beat the Transparency of the Concrete Cabinets of the Raunas. Best ones I could find at any price. (I only auditioned speakers that were less than $10 Grand a Pair). Everything else sounded 'muddied'.
I only got rid of them went I went to Full Range Horn Speakers. Speakers that are 20 times their size!
