Focal 1027 BE break in

Are you using the same amp, preamp and source for both the 1027s and the Ascents? If not, comparing their sound to each other is meaningless.

Furthermore, your office and your home theater room would have to be the same size, have the speakers in the same locations, and have the same furniture and wall and floor coverings....

I'm a two month proud owner. I was fortunate to demo a broken in pair in the house for 2 weeks while I auditioned and awaited delivery of my new pair. The 1027's need some break-in time. You'll find the high's and mid-range to be their strong suit.

My Alto Be took a good 3 months to really break in and sing.

Does 30M2(not dedicated listening room, just normal living room) too small for 1027Be?

30 square meters (about 270 square feet) should be fine.

I do think these speakers prefer a relatively well/damped or "dead" room. If you don't have carpet and not much soft furniture, you might find they sound a little bright in a room of that size.

My room is about 16 x 22 x 9 feet, and I found that I needed to add absorption panels to tame the reflections. I don't have much furniture, and just an area rug.
