How far from the back wall are your speakers?

From the back of my speakers to the wall behind them is 6 feet.

My speakers (Odyssey Kismet Reference floorstanding speakers) are 21 inches from the back wall, although they were designed to be used in that way.

Aside from dipoles, OB's and omni's, the amount of BSC integrated into the speakers generally determines the distance the speakers should be placed from the wall. Unfortunately, that's not an advertised spec. Also found that getting too close to the wall causes a suckout in the upper bass/lower mids as lower bass gets reinforced. I imagine that some speakers compensate for that as well.

So, what I'm saying is that every situation will be different and just try to find the right balance.

Saying that my particular speakers are some-odd feet from the wall doesn't help anybody. Espescially if WAF dictates decor.

The proper distance from the front of the speaker cabinet to the wall behind the speaker is entirely dependent on the particular speaker and it's interaction to your particular room.

Unless your speakers are specifically designed to be placed right up against the wall (ex. Audio Note, Larsen, etc) you will need to use a little trial and error. I have not yet found a formula or modelling application that is 100% accurate.

This depends on the design of the speakers.
