Electrostat transparency from conventional speaker


What should be kept in mind when attempting to achieve the transparent sound quality of an electrostatic speaker from a conventional boxed speaker? Is this more electronics or speaker? Or is it really a combination of the both?

In your opinion, how much does placement or acoustics factor into this?

An electrostat, direct-radiator dynamic, or horn system succeeds to the extent that it reproduces the illusion of a live performance.

Transparency varies more from speaker to speaker than from amp to amp or preamp to preamp.

Low coloration (including smooth and extended frequency response and freedom from resonances & diffraction) is crucial to good transparency.

In my opinion, much of the open and transparent presentation of a good electrostat is related to the radiation pattern. Electrostats have unusual radiation characteristics: Usually line source (emphasizes first-arrival over reverberant sound), usually relatively narrow pattern (minimizes early floor, ceiling, and sidewall reflections), and lots of relatively late-arriving energy to add richness and spaciousness (largely the result of the dipole pattern). In addition, several of the more successful manufacturers go to some effort to keep the radiation pattern reasonably uniform, which is beneficial to timbre because it preserves the spectral balance of the reverberant sound.

In my opinion a low-coloration horn system in an acoustically "live" room does many of the same things well that a good electrostat does. In my opinion it's a bit harder to get the same sort of presentation from a direct-radiator dynamic system. Direct radiator dynamics give you deeper bass and typically better imaging in a smaller package.

If you like the presentation of a good electrostat but for whatever reason neither electrostats or high-quality horns are practical for you, you might consider Maggies, Audio Artistry, Gradient Revolution (I sell these), Linkwitz Orion, and Eminent Technology. If you have the financial resources but not the space, you might consider the Acapella LaCompanella.

In your opinion, why is the sealed enclosure the best of both worlds? What would be a good example?
I'd say your best chance at doing that would be to find a dynamic speaker that has nearly full range out of a single drive element. And one who's drive element has exceptionally low mass and also has a very strong magnetic drive motor.

There are some drive elements that are made primarily for low power SET systems that come close to this equation, although none will actually equal the electrostat for speed.
