We drove up to Crossville Sunday evening, had a great breakfest at Cracker Barrel and went to Cumberland Mountain State Park. The company we work for gave everyone glasses for viewing. Total eclipse, the corona was spectacular. Cell phone wouldn't really focus well, but the event was great.
I have not run into a bad diaphragm on a K-55M that still worked. On some very old K-55Vs, I have seen that they tend to loose output in the area below 1000hz. In that case, a new diaphragm fixes them. As they age, we may see more problems with the K-55M. Also as they age, the plastic ring you have to reuse on the K-55V diaphragm to use it as a replacement on the K-55M gets more and more brittle. When one breaks, not sure what the next move is.
I have tried it in the short time I obtained a pair, before getting them to my dad's. It was upright not on its side. Except for another forte II, it is a great choice. Being used as a center will negate any small compromises being placed on its side. Go for it.
The Klipsch Heritage Museum Association is pleased to offer one pair of Forte IIIs at 10% off MSRP. 100% of the proceeds will go to the Museum. Your purchase will also entitle you to a Khorn Korps Founder's level membership.
Your choice of finish!

there is an ad on filter section from Klipsch the design of which is on line intended to smooth out the top range response when the ti mid diaphragm has been dropped into a loudspeaker originally designed to use the phenoic diaphragm. I have installed the ti mid into my late model Heresy into Fort and Forte ll and into KLF20 and did not find the additional filter was required. I also own Heresy 3 so I do know what this additional filter sounds like. Many seem to think the speaker will not work if yo install ti diaphragm into the mid without this network and that is not the case it is a hi frequency filter intended to smooth a bump at the upper end of the ti mid diaphragm. There is no reason that you cannot install a set of ti mids and evaluate for yourself. You can choose to include the additional filter at any time. the sonic benefits of jumping up to the ti mid diaphragm are not small. the H3 and the CW3 both use the ti mid and while I am not 100% sure I would expect that the new Forte3 also uses the ti mid diaphragm all of those loudspeaker would be using the add on filter for the ti mid.
Yes, there is a better driver, the A-55G. But, look into the plastic back plate on the K-55M. It could be loose as Mookie said in his post above. Usually that shows up as a buzz, but could possibly just cause distortion.
