odd question about stand-mount speakers


Is there any reason you shouldn't turn stand-mount speakers upside down and listen to them that way, as long as you use some kind of vibration control/decoupler between the speakers and the surface they're placed on? The reason I ask is because, at least in a near-field setup, I would think having the mid/woofer ABOVE the tweeter would enhance image height/size -- assuming the tweeter is kept at ear level. (A couple of asides: I don't currently have bookshelf speakers, otherwise I would experiment. Will likely be buying some in the near future though. Also, I know that there are some stand-mount speakers that place the mid/woofer above the tweeter, but the vast majority do not -- most of the ones I'm interested in do not.)

Interesting. Looks like PSB's entire flagship line of speakers have a mid or woofer above the tweeter. They clearly know what they're doing. :) noromance, that's sound advice (pardon the pun). I guess I'm really asking whether there are any reasons unrelated to sound quality that they shouldn't be placed upside down -- like would it put pressure/stress on internal parts in a way they weren't designed for and thus lead to parts failure?

I think you answered your own question when you brought up the position of the tweeter, If the tweeter is at ear height, then demising that position with upending the speaker would not be beneficial, but if an improvement can be had with upending, then why not?

I would think the heavier end of the speaker (woofer) being closer to the base of the stand would help reduce potential speaker vibration

don't forget d'appolito design

my office, real bookshelf speakers (fit on 11-1/2" deep shelf, no rear or side ports)

vertical tweeter at seated ear height. horizontal, tradition says tweeters to the inside due to narrower dispersion of tweeters. 

Both prior Wharfedale's and current restored AR-2ax (horizontal) sound better with the tweeters to the outside. Every space is different.

Yes, a d'appolito design would accomplish the same thing. Plus I wouldn't have to upend the speakers, and the mids/lows would be spread out over two drivers instead of one (per channel), potentially enhancing the sound quality. The only drawback is there are a lot more MT design stand-mounts to choose from than there are d'appolito designs.
