@rick2000 , sorry but no. The ribbons can stretch beyond the ability of anyone to tension them. The ribbons are actually twice as long as you think. You pull the striations out then the ribbon starts to washboard. It is only a matter of time until your grandson kicks the woofer and puts a whopping dent in it, My nephew did that to a Diva. Or, your new cleaning lady takes a vacuum to them to clean the dust off and sucks a ribbon into oblivion. Ribbon speaker are way too fragile for that kind of money. Once the company is gone they will not be repairable. A Sound Labs on the other hand can be kicked, vacuumed , tensioned with a heat gun, banged on and no damage will occur. They will last 10 lifetimes if not more. You have to run them through with a spear to hurt them. The other benefit is the Sound Labs are true one-way loudspeakers there is no crossover, there are no abrupt phase changes consequently the imaging is superior. As they go from floor to ceiling, Sound Labs are true full range line sources.
The other problem for these speakers is Magnepan. The 20.7 is an excellent, reliable speaker from a well established company at a far better price. The tweeter is on the fragile side but Magnepan has an excellent tweeter exchange program. The tweeter is the only true ribbon in the 20.7. It is the most reliable ribbon made as the ribbon is supported along it's entire 6 foot length. But still, a high frequency accident or a vacuum cleaner will take it out.
I am sure the Clarisys are excellent sounding speakers, so weren't the Divas. Having had that experience I would suggest that everyone look elsewhere.
