Hard to gauge the room-my den and kitchen have no true wall between them. There is an L-shaped breakfast bar (with lower cabinets, counter space, and eye level cabinets at the top. To add to that mischief, I have a 15-ft. or so cathedral ceiling that runs the length of the 2 rooms. So, in measuring, I don't know if I should take the kitchen into account. Take the breakfast bar out, it's quite large. Living area is, more or less, an open floor plan.
In terms of knowing about me-I have quite a collection of music-Sinatra (all the old crooners), easy listening (imagine heavy-stringed, sleepy time Percy Faith Orchestra), Elvis (his more mature material post '68), Eagles, Carpenters, Fleetwood Mac, Phil Collins, Chicago, Bon Jovi, and Bruno Mars. Good luck trying to figure me out.
Listening level? I like to feel the music, but not to the extreme of shattering windows.
