Driver spacing. Close or far apart?

[tuxedocivic]

First. I've done searches. Also, I know the rule of thumb is to keep them as close together as possible. Or at least within the wavelength distance.

But I'm wondering. If the wavelength is long enough (XO point low enough), would it be best to spread out the drivers as far apart as possible, if you're only interested in the sweet spot? I haven't come across much on this, although I do recall a designer or forum post somewhere claiming that tall spacing creates a taller soundstage.

Is there an advantage to this?

And I realize woofers in 3way towers are often near the floor to reduce floor bounce. Any other reasons other than this? Thanks.

tricky question.
Suposedly the goal is to have a point like sound source, some manufacturer made dual-concentric wideband speakers just for this reason. (tannoy, i think, but i could be wrong)

if You have a 3 way system then the tweeter can be further away from the woofer, that is correct. With a very low XO point placing the woofers are quite free, think of HT setups and real subwoofers. (not extra bass units, but subwoofers. those that work under 50 hz.)

Actualy "taller" soundstange idea , the whole idea of soundstage depends as mutch on the listening enviroment just as mutch as speaker placement and the speakers them self.

I see no advantage in spacing the drivers in the box, say for a 3 way setup.
Should be close to eatch other as possible.
Other than that it is practical to have the woofer close to the floor.
The floor can act as an extended baffle thingy, it helps low freqvency.
Not to mention that probably the woofer is the most heavy stuff in the box, so it is allso practical too.
At least i think

If your crossover point is low enough where room modes are dominating the response, then the normal spacing issues tend to become irrelevant within reason.

Thanks for the replys. It sounds like there are not many advantages to spacing out the drivers then.
