Ralph, I think we will have to agree to disagree.
My example of the SF Amati Futura is a good example of what I am talking about. Sure, the speaker doesn't know or care what it plays, but I suspect the designer sure knew what it would be strong at. Can the Amati Futura play RAP..of course it can, but you go out and listen to this speaker...and you tell me which genre it is better at reproducing; and by a country mile IMHO.
I've no problem with agreeing to disagree, however its not because of anything other than I don't actually like arguing.
So I will leave you with a little thought exercise: Come up with a methodology that allows you to design a speaker that works great for one genre of music but not another. Failing that, you can ask an actual speaker designer how that is done and his response will be acceptable.
I suspect that the reason you support this myth is that you simply have not encountered a good recording in the realm wherein the speaker you have in mind seems to shine, in this case classical. When people tell me that rock has more this, more that that somehow a speaker that does classical can't handle, all that its telling me is they've not heard good recordings in the failing genre. In this case I have to assume you've not heard classical recordings with a lot of bass in them. I will suggest a few. My guess is that if this speaker can play classical and not rock, the recordings that I suggest will cause this speaker to fall flat on its face as well. One might come away with the idea that the speaker does not do classical so well either. Ultimately neither is really true- what is actually happening is that the speaker is intended to work in a smaller room and at lower power levels as it was probably designed for a slightly different market than we have here in the US. If you take and try to make the speaker play lifelike levels of any genre of music in a larger (read: American) room, its going to have problems!
Here are some recordings (all on LP, BTW):
RCA/Soria series Verdi Requiem, side 1 track 2. Play at a normal level.
London/Decca Das Reingold, Sir George Solti conducting, side 6.
EMI St. Seans Organ Symphony, Luis Fremeaux cond.
London/Mobile Fidelity The Planets, Sir George Solti cond. side two.
and a favorite of mine- Atma-Sphere Canto General, Mikas Theodroakis and Stephan Skold cond. Los Liberatores
I expect what you would see from any of these is that woofer just flapping around- its not going to deal with the bass energy in these recordings at all. Yet at the same time this speaker would likely make a great monitor in a recording studio.
