I am just a jr member but here is 2 Cents.
10' wall to wall, room 10' X 16' X 8' I sit about 8' from the speakers Imaging is great sound is good. Image is so good today I thought my academy center channel was some how being powered, I had to get up and put my ear to the speaker to belive it was not powered.
This is a temporary installation. In 1 - 2 years they will go to a 14' X 20' room.
Heavy vocal tracks sound best, Dave Matthews, Indigo Girls, N. Jones, Tori Amos. I also like Classical and rock. I like it loud and modified ALK x-overs seem to work very, very, well. Horns reproduce vocal & string insruments very well compared to my Forte IIs and the 1 pair of Cornwalls I have heard.
I like to feel the bass I have really liked the khorns I have heard but I am falling for the tight bass in my scalas supplemented with a sub especially when listening to 2 channel. Tight bass down to 60 or so and subs that go lower than the K-horns. They do not move air like the K-horns but sound very musical, precise and distortion free.
I also have a Velodyne SPL-1500 R sub. Plan is to add 2 Velodyne SPL-1200Rs for 2 channel and keep the 1500 for a LFE during Surround sound. I had Forte IIs for 16 years that went low but the Scala bass is much tighter and only needs help from the sub less than 60 hertz. I have the sub xover set at 55hz which seams to be the best blend. I do not have a meter but through trials I have come up with 55. The cross over meter has been said to be within 3 hz.
