which excels at Rock and Roll

I think Class D never works with Mumblecore.

@robshaw  Your opening comment "Room is 14X14' No treatments, but, room currently sounds great" has me perplexed.  Everything I've read on listening rooms says the worst is a square box.  I can only guess how much better your system would sound with acoustic treatment, regardless of the speakers you go with?  Just a thought.  Cheers, 

For rock, pop, percussive, symphonic, and electronic music you need good speakers with good dynamics.  The rest will sound as it should as well.   So speakers like that can handle all music well and are not genre specific.  Planars and Electrostats tend to have limited dynamics so not as good for the types mentioned above and therefore are more genre specific.  But it’s hard to make the case a speaker is top notch when it can’t handle all kinds of music well. IMHO based on years of experience, that is. 
 

Size matters as well depending on room size and ability to go to lifelike SPL levels, though not all may necessarily need that.

Absolutely FALSE....but let us get to the bottom of it a bit.

Here are 2 speakers that i personally own, which are made by the same manufacturer even....

Let us consider this track by thin lizzy (one of my test tracks) with Brian Downey on drums doing his thing back during his younger days. Play this track at 100db+ and you couldn’t for the life of me (or for another 50 lifetimes) tell me these 2 speakers are genre agnostic and will fulfill this track the same way. 99% of listeners who have half a wit about rock would pick one of these (and not the other) as their preferred sound, i would bet..

Or try this...i am sure it is a fan favorite around here for small rooms...Play that track at a 100db+ on this li’l.....and tell me with a straight face that speakers are genre agnostic.

Even a speaker savant like Andrew Jones is on record saying that he’d get very shaky if someone asked him to design compression drivers and a big ol’ horn speaker. 

I haven’t seen any speakers on your catalog, but, as an amp designer,, you seem to be repeating this genre agnostic fallacy on different threads. I understand that you are required to cast the widest net possible (to capture as big a market as possible for your product) as a manufacturer, state that your gear would work just great for every genre...I would really hope this forum in not filled with noobs and folks here have a reference point for different types of gear, understand that there is no genre agnostic audio equipment.

You could keep showing a sinad chart, FR chart and keep repeating the fallacy perhaps or the guys at that one "measurements only/no ears" forum might..... But...i really am not sure how you all could repeat this fallacy with a straight face.

@robshaw Speakers and electronics don’t care what music you like or don’t and don’t favor a certain genre. That is one of the most common an persistent myths in audio. 

It really is a myth. No-one has found a way to design either amp or speaker to favor a certain musical genre. They are equally good or bad at their jobs regardless of the genre. 

I have Ls 50 metas + powered sub.  This is a very highly regarded setup FOR THE PRICE.  Absolutely genre agnostic as well I would say.   But only up to about 90db SPL in a smaller room.  Again, genre agnostic.  To go louder in bigger rooms there are larger and more expensive models to choose from.
