The first louspeaker of it's type:
This incredible speaker system, the Quadrupole Σ Waveguide woofers address the room with physics and science unlike any other speaker ever produced before.
When most speaker companies make a flagship product, they are just simply large versions of existing technology and they charge a fortune for them with no new intellectual property or patents.
Eminent Technology’s flagship loudspekaer has three granted patents, a new three way planar push pull transducer arranged as a quadrupole with neo magnets, and an entirely new flat woofer technology, the sum of these minimize room reflection and room modes, a new way to produce sound in a room.

This is a new Loudspeaker created from First Physics Principles
There are plenty of loudspeaker measurements that don't really tell you how a loudspeaker performs in a room.
Why a quadrupole makes a better loudspeaker:
Here is a Energy Time curve (ETC) comparison of the Quadrupole + Waveguide against a conventional direct radiator speaker in a 15 x 25 x 8 foot room with NO room treatment at all. The microphone was about 2.5 meters from the speakers at the listening position.
The Energy Time curve shows us how sound energy from a loudspeaker decays in a room over time from an impulse.
Inherent in the design, a conventional loudspeaker has a significant number of higher energy early reflections. Usually from wall, floor, and ceiling surfaces.
In the first 12.5ms a quadrupole has four times less reflected sound energy reaching the listeners ears!
The greater reflected energy over time from a conventional loudspeaker is a direct result of the loudspeakers directivity, since conventional speakers tend to radiate energy hemispherically, reflections from a room change the timbre and clarity from the loudspeaker. Br design, the quadrupole does not create early ceiling, floor, or sidewall reflections.
The ETC shows us how a loudspeaker speaker interfaces with a room environment, and in any room, a Quadrupole will excite the room LESS (why listeners use room treatment) and sound at the listener will start and stop much faster with much more detail!
If you are designing a loudspeaker from first principles, you would not create a loudspeaker that introduces a large number of early sound reflections and arrivals all delayed slighly (milliseconds) along with the desired signal and depend on your ear/brain to sort it out. You would also not design point source woofers that excite dozens of low frequency room modes which cause 30dB swings and infinite dips in room frequency response in multiple positions around a room.
