What a great thread! Just read every word, like a novel I couldn't put down. It has changed my perspective; I'm now convinced that my Klipsch Fortes are mini-monitors. Thanks to RS Steve for his effort and research, and for sharing it here.

Hard to imagine going back to laptop or cell phone speakers again isn't it?
Kidding aside, this thread is a very enjoyable and informative read, thank you for documenting your work and research so well for all of us.
You guys seen that ad on Tampa CL. Looks like he has a ton of gear and he mentions having Model Elevens.

This Dynaco ST-70 seems to have just the right amount of wattage to bring out the best tube sound through the model Eleven's. There's nothing quite like having a concert in your own living room! These Fraziers's just keep on impressing me. :thmbsp:![]()
I always thought those Motorola piezo tweeters were a unique feature of white van speakers?
In part, but they were also used other places, such as in the renowned Dalquist DQ-10.

My first good speakers were Frazier MK 4 s . Those had a 12 inch woofer 2 - 4 inch mids
And single Piezo tweeter . I bought them in 1976 for $ 400.00
I remember them being very efficient .
They look shorter, did you take the wheels out from under them?
