Planars/ Electrostats benefits over box speakers?

The Mangaplaner 20.7 is one of the better bargains in the speaker world: fast, transparent, full range and not too hard to drive.

The Sound Lab is the state of the art in ESLs, and much easier to drive than Martin Logans, and usually have greater sound pressure capacity as well as deeper bass.

Both speakers have tube and transistor advocates.

Planars have a backwave that, because it arrives later than the front output of the speaker, aid the ear/brain system in improving sound source location; IOW imaging and depth.

All speakers have a backwave. Its more a matter of what frequencies are contained in the backwave and the magnitude. Planars have more of both than most box designs. Omnis also have more of both and also have a more 360 degree radiation pattern as opposed to a simple backwave firing 180 degrees in the opposite direction only.

The omni 360 degree dispersion pattern is more like what occurs when sound is generated in real life. IMHO, omni presentation is more realistic/lifelike in general as a result, but planars are a step in that direction compared to most forward firing box designs.

The wvefront generated by an omni is also phase coherent in all directions which results in a very coherent/natural sound.

Planar backwave is not in phase with forward firing wave. As a result, planars can have very holographic imaging when set up right but it does not necessarily sound coherent and natural like an omni. Its like listening to a gong strike. Very holographic and impressive with lots of sound everywhere but I find I do not enjoy planars nearly as much as I used to when I hear them now that I am acclimated to very high quality omni sound. The coherency is just not there. Except for things that radiate sound like a gong. :^)

I don't know if you've ever tried it, but putting some type of room tuning product right behind the panel helps a lot.

Zd what's behind the speakers and distance to it certainly matters and worth tweaking for owners but I've moved on to omnis and not looking back anymore

I use to own a pair of Mirage M3's (Omnis)circa late 80's, that were very good at putting out a huge deep presentation, very detailed and dynamic with the McIntosh 300w/ch amp. I miss that sound, very wife un friendly though. I regretted the day I sold them. But O well, lesson learned! (don't let your wife make you sell your monoliths) Since then I have moved on to a conventional box speaker and I really like them as well :-) Maggies never grabbed me the way the M3's did, I will say.
