Providing the big hall sound does mean a tradeoff. Pinpoint imaging is sacrificed along with the single position ultimate sweet spot.My system does not seem to have that tradeoff. I get pinpoint imaging along with a huge soundstage- the bigger the room, the better.
I like to play King Crimson's Islands at shows- the string bass in the first track is very natural and the bass drum later in that same track is quite visceral. The shimmer of the cymbals in ELP's self titled first LP is wonderful- I have a Pink Island copy which is a bit smoother and more lively than the US vinyl. The guitar sound on Yes' The Yes Album (plum label UK Atlantic) is just like the amp is sitting right in front of you.
Meanwhile EMI made some impressive classical recordings about the same time- one of them, The Wand of Youth I like to play as a demo of depth, detail and dynamic range (Wild Bears track). So when its a 70s recording, is that just rock or is classical included? Does it matter if its Kraut Rock, British or American?
The fact of the matter is speakers have no taste of their own and a good speaker is equally good at rock or jazz as it is classical or folk. The idea that a speaker is especially suited for a certain period or genre of music seems to be one of the bigger myths that exists in audio.
