I don't want to start a flame war on this, but here is some truth.
I can say this after having some personal conversations of owners in the past, and other owners of all kinds of similar speakers in the past that use some of the more exotic drivers it ultimately comes down to "Overrating" industry trends, and end up in many overpriced materials used in designs because everybody jumps on the supposed most advanced bandwagon to compete at your local Audio Hotel shows.
First off the more "Exotic" the materials used in acoustic designs from my experience, and in my opinion the more risk they are not going to be as stable, or musical to the average human.
Take Kevlar drivers, or ceramics like the Accuton, some composites, etc...
The only thing I have truly heard that can be used really well for the money is the Diamond, and Beryllium tweeters in some designs. However, honestly from owning multiple designs using Aluminum, Kevlar, Ceramic, and even "Polyglass"... The best of the best for midrange, mid-woofers, even SUB woofers 9 times out of 10 ends up being the most natural material, and cheapest still available... PAPER!
Obviously depending on the treatment of the paper for durability, deterioration, and implementation will vary, but it sounds good. You want musical go with the companies that get the basics right, and get you to the promise land without overhyped / overpriced drivers..
You can argue all you want that paper, or more standard drivers are not as capable of the dynamics, or accuracy many of these off the shelf exotic drivers produced in the last 10 years provide, but you would be wrong sorry.
Not the best analogy, but live music for P.A. Reinforcement, and many professional applications including all your run of the mill guitar amps, speakers whatever still use ... That's right PAPER! And they are as efficient, and in-destructible as any exotic 86 to 88 db home drivers, and they ain't got no ceramic drivers that made that music, or mastered that music most of the time. All these super Audio materials are simply a business within a business if you know the real sound results.
So sometimes this could just be a case that the simpler the better. I have a 30 year old pair of high efficiency horns with Titanium tweeters that can slay anything from these newer box designs, even the newest Avantgarde Horns don't surprisingly add much to the equation with advanced horn designs. In the end synergy is everything when you want to get the to best results not the most exotic box with exotic European drivers dropped in it.
I am not saying there is ultimately a right or wrong here, but sometimes you gotta realize you need to go with what works, and makes you happy so maybe a few in this thread are correct... Stop fighting yourself, and change the speakers. You want less ringing, or abnormal response a lot of the time basic materials will excel in your extended listening sessions regardless of acoustic conditions.
I figured the name of the thread was "Are the SS8's the wrong speaker for me?" so the answer is simply they might be!
