Home Speaker Asylum

General speaker questions for audio and home theater.

an adjacent room can serve as a bass trap and, if so, how would that work?

An open window or door to the outside is a great bass (reflection) trap.

Any room opening that reduces reflections between two opposing surfaces inside your room would be working as a bass trap.

A rough rule of thumb: If a room opening is more than 1/3 the area of the surrounding wall, the bass may not even "see" that wall, and may bounce off a wall of the NEXT room before returning to your room.

I suppose you could measure this with a door open, and then with the door closed, assuming there was a door.

An open door to another room can also act like a speaker port, with air in the next room resonating at a certain frequency ... and a hall can resonate like a speaker port, or act like an echo chamber, especially if behind your ears.

All these potential problems are why I bring my stereo outside and listen there.
