This can produce a thin sound in the lower frequency ranges since you get more cancellation from the out of phase woofers.
A lot of manufacturers use only 1 woofer and 2 tweeters wired out of phase for this very reason. Also I noticed that some surround full dipole speakers are actually adaptive dipole, they just don't advertise it that way.
I believe the term Adaptive dipole was just a catch name given by marketing, who knows.

thanks for the explanation.

So by doing Rjax suggestion they should sound better?

I think so. When I converted mine to monopole (bi-pole), I liked the sound better. That is why one guy put in switches so he could easily play around with all the configurations to see what he liked best.

To clarify (or possibly correct?) the RS-300's are not adaptive di-pole speakers. And no, it was not a marketing term conjured up in some brainstorming session. AFAIK, it was first used with the Citation products manufactured by Harmon Kardon. The Citation line was their one and only foray into ubber high end speakers and electronics. They made a surround speaker which truly was an adaptive dipole (and was named as such) and was part of their THX line up of speakers. They simply had numbers. The dipoles were labeled 7.3 THX IIRC. I could go take them off of my wall to be sure, but I think that is correct.

Anyway, they were designed to work hand in hand with the Citation processor so that room sound could be configured and changed with a flip of a switch (either manually with a switch on the speaker) or push of a button on the processor. It would change the surround paramaters from a dispersed dipole to a more direct bi pole sound field. It really was revolutionary and way, WAY ahead of its time.

All of the Citation gear (especially the elctronics - processors and amps), is still highly valued by collectors and audiophiles alike. That gear seems to hold value extremely well and is generally snatched up quickly when it comes up for sale. It really was ahead of the curve when it came out. It's a shame it didn't last.

Thanks
