quick and dirty Elipson Planet measurements

[CINERAMAX]

Hi Peter,
Thank you for showing us the "behind the scenes" implementation of your teams design.

Im looking at these systems from a purely "hifi" perspective.
I would like to ask of the customers who come to you for a turn key solution, do many concentrate on the raft of DVD music concerts available.
And if any also want to use the system and a pure stereo system?
A movie soundtrack is a fiction, created by the sound engineer and the director.
Whereas a music concert is an actual "performance" that is captured then re-engineered to create the original.
So a critical "audiophile" customer may be a different matter, or a correctly designed system will meet both criteria. (Hifi & HT)

I am an amateur HT person who only plays music DVD of my favorite artists in the same way I play stereo recordings. Its just an extension of hifi with pictures. I find the 5:1 Music DVD's just as well recorded and mixed as my standard stereo recordings. So believe the source material would translate to the same level of accuracy to the original than that of a movie soundtrack.

The money involved for a Skylounge system is around the same price for a "SOTA" hifi system but with some much more.

Due to Infocomm, I need to postpone the lecture on the two kinds of archaeoacoustic soundfields. In the book titled "Epinomously," egocentric soundfields are defined by the first 3 as follows:

- **60,000 BC**: African echo valleys
- **15,000 BC**: Altamira Caves
- **700 BC**: Druid circles
- **1974**: Quadraphonic sound
- **2022**: Atmos music

These soundfields seem to resonate at a DNA ingrained level.

On the other hand, allocentric soundfields, a relatively recent development started by the Catholic Church around **700 AD** in the first cathedrals in Southern Europe, were characterized by Gregorian chants in large rectangular spaces ( NEW TECH at the times). In these setups, sound emanates from the front and reflects at the back in a rather symmetrical fashion. This soundfield venue type translated into classical music concerts and later popular music concerts, with amplified sound using compression driver technology. However, some harshness from these amplified concerts can bleed into the rear surround of the recordings, making it less than an ideal holographic experience.

This is the general direction of my whitepaper. If you are interested in exploring the ultimate holographic musical soundfield, consider a speaker that is both coherent and acts as a radial diffuser while being boundary-decoupled by pendants, thin stands, and wall mounts. These concepts are fundamental, especially if you have 14 of them in a room, each costing €500 for the basic model. While they are not at a Skylounge level monetarily, they are certainly top-of-the-line in a David vs. Goliath Multichannel Critical Listening way.

These speakers are not yet available in the USA, but they will be soon, including their amplifiers, which extend down to 2 Hz with very low distortion. I am planning to ask Elipson to send one to Audio Science Review (ASR) for evaluation.

Equally important, there is a ranking of multichannel audio music that will infuse some psychedelia into the psychoacoustics. I will share that when I come back...

Till the 3rd week of June, Cheers!

Interesting Speakers - but, given the price, why should one choose them over e.g. the KEF LS50 Meta? Both are esthetic but the latter measures nice.

A direct comparison may be warranted. For example, in 1956, RCA conducted extensive research on various cabinet shapes for what was then considered a single full-range driver. Surprisingly, the cabinet shape that yielded the greatest response curve, with all other factors being equal, was the sphere, which is ideal for coaxial drivers. KEF speakers, such as the LS-50, are designed to be placed against the wall, but their backs are not aesthetically pleasing. In contrast, these new speakers are visually acceptable from behind. A pair is currently on its way to Amir for evaluation. These Planet L speakers, which also function as in-room radial diffusers, significantly improve their perceived quality with increased numbers interacting with each other and the room. A two-week retrofit still requires 20% of the surfaces to be absorptive, but 15% less diffusion than typically needed, thanks to the contribution of the speaker shapes and their free-floating, optimal point source positioning made possible by the four mounting options.

For Atmos music, the combination of these speakers and their substantial radial diffuser enclosures, along with their reminiscence of 1950s sci-fi design, creates a synergy that enhances the audio experience for most listeners who sample it. Interestingly, there will be an improved model next year that looks exactly the same on the outside.

wow

are they oval ?

Thanks for the link. My speaker enclosure is the final one for me. I will continue to upgrade only the drivers, which are being developed for a second model. As for the enclosure, it's a keeper for my 7.0.4.
