Speakers that disappear


I have been listening once again to mbl 101-Es last weekend and have been very impressed by the great illusion they create just by "disappearing", i.e. I could not localize the speakers with closed eyes.

Listening to these speakers got me interested again in speakers that create a large 3-dimensional image, "disappear" and do not sound "boxy" in the low frequencies (with boxy I mean that the base somehow sounds constrained by the loudspeaker enclosure, especially the massive drivers in the B&Ws and Kefs gave me that feeling, the very low frequencies had a slightly "wooden" sound to it - I listend to Richard Wagners Valkyrie amongst others and drum strikes suffered in particular).

[I am obviously aware that there are many other characteristics that are required to make a great speaker, i.e. transparency, etc. but i would like to focus on the above in this thread.]

The only two speaker brands I have listened to that did the trick in this respect for me are:
- mbl (the 101-Es, dont know if this applies for their smaller speakers)
- Wilson Benesch (ACT and Chimera, not as strong as mbl but still pretty good - unfortunately a bit too week below 40hz, even the Chimera)

In comparison listening to Sonus Fabers, Kef References, B&W 800Ds, Ayon all of them sounded "boxed in" in the low frequencies and the sweet spot was much smaller and perfect toe-in was far too important for getting a decent image and illusion. (I know these speakers do some other things very well so no need to mention)

Now there are a lot of other great speakers that I could not listen to yet. Therefore I would love to hear some opinions about the ability of some other speakers to create an illusion by disappearing and not sounding "boxed in".

One type of speakers that do a good job in the above seem to be planar speakers but I have listend to both Martin Logans (dont remember which one as they all look so similar) and Magnepans (1.6 if I remember correctly) but somehow they did not do the trick for me and while they disappeared the soundstage sounded a bit flat and lifeless to me. (Both were driven by McIntosh Pre and Monos).

Particular speakers I would be interested in are:
- Magico
- Wisdom Audio Sage Series
- Rockport

At this point I prefer soft dome and paper/carbon type drivers and have not been a fan of ceramic drivers, beryllium, diamond or aluminium tweeter (in those implementations that I heard). Nevertheless there may be great implementations that do the above very well, so I would also be interested in opinions about:
- Kharma
- Focal Utopia Series
- Revel Ultima

Also are there any mid-price speakers that do this well?

Don't forget Verity Speakers like the Parsifal Ovations or Sarastro II, these speaker totally disappear and do not sound boxie in any way.
Sounds like you should consider open baffle dipole or other omnidirectional speakers, the latter with sealed acoustic suspension, not ported woofers. (Curiously, the MBL has a bandpass bass unit, no?) And research active (but not necessarily powered) speakers, especially if you listen to large scale orchestral music, such as Wagner, Mahler, Tchaikovsky. Look at the Linkwitz Lab Orion (open baffle dipole, active), it will out perform anything in your price category. You might also look into Morrison Audio, available in both passive and active versions.
OHM Walsh speakers are mid priced and have some similarities to mbl imaging. To differentiate the two concisely, OHM is perhaps more coherent top to bottom than mbls I have heard as a result of the wide range walsh driver used (German Physiks is the other well known brand that uses these) and are designed to go closer to walls and fit into most peoples rooms easily. mbl requires more distance from walls and created perhaps the deepest 3-d soundstage I have heard during audition.

I've also heard good things about Morrison speakers in regards to 3-d imaging but have not had the pleasure of listening to these.

I also have a small pair of Triangle monitors that are extremely fast and disappear about as well as anything I have heard.

Magico Minis did the trick extremely well also when I heard them (not midpriced though).

Some PSBs I've heard are mid priced and do the trick pretty well also.
