Hello Serge,
I have been a Klipsch loyalist for longer than I care to mention. In fairness,I am biased to the Klipsch sound.
Like you, I had the same question regarding the LaScalas. My music room is smaller then yours.
Dennie, linked my post from just over a week ago to yours.
Fate delt me a kind hand, and thanks to a wonderful member of this forum, I just fell into a great pair of 1988 LaScalas.
Let me tell you that when I listen to music through my LaScalas, the walls in my small room melt away. The LaScalas transform my room in to the worlds finest concert hall.
The sound stageing is remarkable. I really love how they sound at low volume. I have owned Haresey's, Cornwalls, KG3's, HereseyIII's, and each of them are wonderful loud speakers... But these LaScalas,are incredible!!!! And when you dial up the volume
you become that old Memorex tape advert. the one with with the guy sitting in the chair infront of the speaker, his drink getting blown over.
Get a pair, your only regret will be that you didn't get them sooner.
In my opinion, your room size will work out just fine with the LaScalas. They are that good.
Wecome to the forum.
