Are there any current high end dipole speakers (dynamic)?

I have a set of Spatial M3s, love them. Great tunes fill my 24X18 room powered by my 24 watt EAR Yoshino V20. They’re accurate, holographic and create a great sound field and soundstage. They also can handle big watts too. You can be very happy with the M3s.

There are several, including some of those mentioned, but some of the best of any type are:  

1.  Legacy Audio Aeris - can match or better pretty much anything of any type available.
2.  Nola's - but they're expensive
3.  GT Audioworks - outstanding
4.  Spatial Audio / Emerald Physics - great values, but may not have as great a treble as some of these others.
5.  Magnestand modified Maggies - much better bass and dynamics than Maggies - but, also a great value.
6.  Eminent Technology LFT-8b - great value and great sound.

There are others, but these are some of the best.  I have the Aeris, Magnestand Maggies, and Emerald Physics, which I would rank in that order.  They're all great - but, the Aeris is simply one of the best speakers available.  

Oh, no... I almost forgot some that are right up there with the Aeris in their sound quality - the Linkwitz Orions and LX-521's.  

I also have the Orions, which I'd rank with the Aeris, or very, very close, as are the LX-521's.  

The drawback - they're kits from Madisound, though you will find them available for sale used, occasionally.  They are great values also, at their used prices. 

And... I guess to be fair... the latest designs of Spatial Audio, like the X3 and X5 have AMT ribbon tweeters, which much improves the treble quality, over the earlier models.
