Rock and roll speakers?

Klipsch forte or forte ii Or heresy.

R&r, you are welcome.

Easy question, easy answer. The reason is the high efficiency and relative affordability of those. Tekton and zu are other similar options in that regard.

"If the speaker is good for one genre, its good for another, plain and simple"

I agree with that. I think the questions come more from teh perspective of finding speakers on a limited budget that will tend to have more performance limitations. In that case, some speakers may well be found to do better in one genre than another.

Inexpensive speakers of good quality are usually more limited in overall magnitude of output and dynamics. Or some may go louder and clearer but be less refined otherwise. In any case, there is a significant compromise somewhere.

Some will provide more potential for dynamics and output levels that benefit some forms of music, like large scale classical works, rock, metal, big band, etc.

The best strategy on a limited budget is to forgo the lowest octaves, which requires the most to do well. Lots of ways to skin the cat once the power demands of the lowest frequencies are out of the picture. For a lot of rock/pop music in particular, it may not matter much if not much occurs below 50hz or so but the rest is good. Hence a good rock/pop speaker.

Ray I see you have Magnepan and Klipsch. That would seem to have all the bases covered pretty well. I had Maggies for years and listened to everything on them. I would not call them "rock and roll" speakers though. I just heard the latest and greatest Maggies again this past weekend and though impressive with most everything. I'm still not sure I would call them that. Reason being that to me at least you have to be able to feel rock and roll speakers on occasion as well as hear them. With most any speakers using non dynamic drivers, its usually all hear and little or no feel in most cases. Its a subtle distinction but an important one for a rock and roller though I think.

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.

I am a Dynaudio fan as well though might not always be everyone's cup of tea. What is?

Dynaudio packs a lot of quality and a fair amount of quantity into their products. That makes them fare well no matter what you throw at them in general.
