Years ago, someone gave a pair of OLA size speakers,,, in walnut veneer cabinets, that I connected to my Sansui 800 as a channel B option... They sounded pretty good... I moved them for painting/remodeling, I don't remember, and stored em in the attic for some time... A friend wanted to put together a system, so I dug em out and gave them to him... He said they didn't sound good,,, took the covers off and saw the "speaker cones" desinigrating, so he trashed them!! Now I never heard of AK or any other audio forum back then, but would have researched em before chucking them in the trash!!!
Never knew what they were, but I'll bet they were decent, and could have been refoamed,,,
If knew then what I know now!!
