As Sogood51 said

"Large speakers with truly deep bass response will not sound good as is unless you like...BOOOOOM".

I thought that one important aspect of High End audio was unrestricted low end. If you are in the process of building or remodeling the cost of a bigger room is probably less than the cost of all the room treatments you will otherwise need.
well mr. Gregm. you would be surpriced over the prices on stereo equipment in denmark.its normally double up us prices.
i need a set of speakers, a cd/dvd player, amplifiers, tuner, plasma screen, cables. not surround sound.
i will see if i can get a carpet on the floor and some absorbments on the walls.
Concrete will not absorb low bass, bass notes will linger and build with-in the room in a cascading mix and become less than real sounding...bass should growl at you..not shout.

Sogood51...I understand your point about reverberation in a concrete room. My point is that for certain kinds of music, jazz in a cellar dive or organ in a stone cathedral, that "cascading mix" of reverberant sound is exactly what is needed for realism.

Of course, my room is not concrete. I am just making an observation about something (unexpected) that I have observed.

Sounds good to me! I think rock sounds best played over big PA systems to be honest so can understand your observation and agree that it would (could) sound more LIVE (real) in some cases.
