Smallest room dimensions for good bass to 20hz


Woundering how small of a room can you build and still get good bass responce to 20 hz.

Upper corner front left to lower corner rear right need to be 1/2 of 56.6 ft. That length works out to be the SQUARE ROOT of:
[(square root of: L squared + W squared) SQUARED + H squared]

Of course if your listening room has at least one wall which has (roughly) half its total surface area open to an adjoining room, you need to measure the longest top-to-bottom diagonal of the combined spaces ;-)) Have fun!
If you are going to the expense of building a dedicated room, why not get an acoustical consultant like Rives in to help you out?
Sarcher30,

Swampwalker offers some good advice. If you are going to the expense of building a dedicated room, get some professional advice. I've never used Rives, but I've checked out their website and their rates seem to be very reasonable. For possibly less than the price of a component upgrade you can get a customized room layout showing size, materials, etc. Heck, if you get it right the first time using professional advice, it could actually save you money in the long run as it might prevent unnecessary upgrades in an attempt to overcome bad room acoustics.

Just my $.02 worth......

Enjoy,

If room dimension had to equal wave length in order to reproduce a frequency of sound, what would one hear in a earphone or headphone?????????? nothing at all but very high frequencies?!!!!!
Kanuk, the space between the headphone driver and your eardrum is not the same as the space in a room between the speaker and your ear.

To vibrate your eardrum, the air in a whole room must already be vibrating at (whatever) frequency.

A headphone driver uses the air between itself and your eardrum as a 'fluid coupling', using it to 'grab' your eardrum and shake it back and forth at the same frequency.

Once again: "The longest room dimension has to equal HALF the wavelength of the frequency you want to produce in it. ;-)
