The best speaker you ever heard?

Curious how the wood glue tweak improves with time, that stuff dries fairly quick. I guess it stiffens and damps the drivers some, but it seems strange that it would make so much of an improvement. Anyway hopefully more people report on this, it is intersting that such a tweak could transform the sound. What other speakers have owned before the 901's?

Travbrow , I had some used Quad ESL 988's before the Bose 901's.

These modified 901's are taking a very very long time to break-in really good. As the months go by the total balance is getting more refined and its no telling how much longer its going to take to sound their very best.

I'd give them a good 18-20 years.

Being an owner of these speakers, I am biased of course, they are the best speakers I have ever heard. They just get out of the way of the music.

Not full range but the midrange is almost perfect to my ears. A little subwoofer augmentation puts these up against anything on the market IMHO.

I believe 25 to 30 years to be safe.
