Does room size affect volume and bass?

I listened to a pair of Sonus Faber Electa Amatour II, I love them, only one problem, when I have one of my Reference Recordings with the Dallas Wind Symphony on, when it is playing loud, like around 90 DB and the bass drum cracks the speaker cone reaches excusion. This was at my dealers room which is 4 times the volume of my 19x13x8 room. He said that if the speakers were in my room playing at the same volume, they probably wouldn't hit the cone excersion. What do you think?

Ignore that dealer, he is dead wrong. The room's volume has ZERO to do with cone excursion. Only if the speaker is receiving less power from the amp, will the cone have less excursion. If you are actually playing the speaker quiter, but the SPL at the listening seat is similar to the higher power in the vary large room (because you're closer, and the room is smaller) only then will the cone move less. I build speakers...

QED: Room volume affects power necessary to produce desired SPL hence cone excursion, indirectly, but most certainly.

Incidently, the size of the room will affect the bass simply because of its dimensions, because a 40Hz tone, which so many claim to produce, has a wavelength of nearly 30ft.

IN DEALING WITH ROOM SIZE, ACOUSTICAL PROPERTIES OF THE SPEAKER AND WHETHER THE ROOM IS A SOFT OR HARD ROOM PLAY A CRITICAL PART, NOT JUST THE SIZE OF THE ROOM. HIGH FREQUENCY ROLLOFF AND SOUND ABSORBING ROOMS CAN CREATE HAVIC. CEILING HEIGHTH SUCH AS HIGH VAULTED CEILINGS CAN EAT UP SINE WAVE ENERGY AND LOSE SOME OF THE EFFECTS OF THE AUDIO PROGRAM IN THE SOUND REPRODUCTION. THIS IS ESPECIALLY TRUE IN REFERENCE TO THE PROGRAM MATERIAL YOU USED. A PARAMETRIC EQ AND SOUND ANALYIZER CAN TELL YOU IF YOU ARE MISSING OUT.
