which excels at Rock and Roll

Those Acora MRBs have sounded sensational at shows.

I didn’t read all the comments but if you want a REALLY good rock that’s also a really good speaker in general, check out the Volti Rivals. I owned & enjoyed some good Dynaudios & have heard many of the other suggestions mentioned many of which are quite good in different ways but none can do rock like those Voltis. Additionally, you only need a good 20-30 watts to make them sing at almost any volume in a big room. They truly sound like live music & not hyper detailed hifi. 

Next thing you know,..he might claim his 'genre agnostic' tube amps might just work great for every kind of speaker I have and my entire music collection spanning every genre available.

The ASR guys and their 10 dollar chip amps with off the charts sinad might do it too.

I should only buy the asr chinese chip amps and atmasphere tubes. It's all I ever needed apparently!

Ralph Karsten (atmasphere) always makes his above argument. And while in theory it may be correct, in practice it is not. Just one example: If you want to play AC/DC or The Ramones at 100dB, the QUAD ESL is a bad choice; a pair of them is not going to last very long if you do.

I agree with Atmasphere in that I have always believed that if a speaker is better with certain types of music than with others, it only points out that the speaker is weak in some way.  A really good speaker will perform equally well with all kinds of music.  Choosing a speaker for one kind of music is only surrendering to it's shortcomings elsewhere.

If you want a speaker that is great for Rock, beyond being a really good speaker to begin with, the only real requirement is that it be great at very high volumes.

Wrong, you could end up with cost no object speaker that’s just a bit too laid back without the throw, for example (been there, done that)....and not a in your face grunt that works best for rock.

"A really good speaker"...mostly exists in the imaginative plane.

When a guy maxed out his wallet, he imagines that he’s got a "really good speaker" that did it all...how else could it be? his wallet depletion had to count for something?
