I have a pair of the Innsound MKII, are you sure you can handle an 18inch sweetspot.....and this is no joke! It will sound like it is another room outside that area.
I am not sure how well you will like them for rock and punk because so many recordings are low quality and they are almost criminally revealing speakers, however they do very special things when set-up properly and can be amazing, much better bass integration than most Logan's.
My pair is currently at a friends house in our audio club, he is buying them but going to be keeping a pair of cone and dome speakers for when he wants more fredom of movement in his room.
Make sure you here the Innersounds before you buy, this speaker more than 90% requires a detailed audition, but its major sweetspot flaw will take you under 1 minute to discover.....good luck in your hunt!
