Rock and roll speakers?

"Musical demands" on speakers have far more to do with output levels than styles of music, and to say that "no speaker at any price has yet to achieve perfect balance in all regards" is silly...any well designed "full range" system will play anything well, and the best play everything VERY well even at annoying levels. This is the real world...mini monitors with subs will do serious Rock and Roll and large, horn loaded, high output speakers can make softer chamber music sound amazing...I've used both types for decades and can verify this as fact. I say ignore preconceived mythology and understand that size matters (amp output, driver capability) for output level only, and recordings of even the same style can vary mightily in output...I have jazz piano trio recordings that require me to turn the sub down as the bass and kick are too hot, and electric bands that require a boost...but to think musical style will be challenging to a system based on style itself is not thinking at all.

^Sure, there's no difference at all between listening to Barber Shop Quartets and Wagner. There's no difference listening to multimiked compressed pop music and Blumlein recorded symphonic music. Solo harp music and solo drum music. There's no point in trying to make better speakers, as all speakers already play everything well.
I think not.:-)

Unsound....no one made the claim you are making. "Now back to our regularly scheduled program". ;?)

And, seemingly, there's no point not worth missing.

Yep size still matters when it comes to full range speaker output capacity, which is the main factor to consider to be able to play all kinds of music. If it can play the big stuff loud and well it can play all the rest. I think that was atmasphere's point that I agree with.

However, technology has evolved to enable somewhat more output from smaller speakers as well since that is what most people want. Although more of the same can only be better. Its all a question of how much you need. After that the rest is mostly what flavor you prefer. Most people prefer vanilla.
