Hello, I am new to here.

I am a beginner in home audio. Since I am moving to a new home soon, I want to look for an entry grade stuffs.

I like pop, rock, country and some band sound too. However, my listening area would be my dining room too, which is quite small indeed. I think it will be around 9ft x 14ft in total. And I don't hear really loud...
I have just been to a showroom yesterday, with a B60 and FB1+. The result is absolute fantastic. But there are no GB1 for testing. And the showroom is around 250ft to 300ft. I worry about if B60 is able to control GB1 too (GB1's 87db vs FB1's 90db). Or if I use FB1+ in my room, will there be booming of bass??
Anyone can help?
Many thanks here.
Ted
