                     Innovation Technical Overview of new issued Patent US 8,068,618 B2
 
OMNi Sound is a patented solution that combines a unique head assembly orientation of two or three way speaker systems, in a combination of ported and non ported enclosures for the reproduction of sound in an omnipresent manner throughout a 20~20000Hz. frequency range. This is achieved by means of dynamic crossover circuitry and some exotic materials for the speaker elements. Tests demonstrate their performance in a wide range of desirable overall sizes: from the smallest application, a mini speaker, to the largest free standing pyramidal frustum floor models and pro audio non powered loudspeakers systems... OMNi Sound currently has four U.S. patents US 5,847,331,     US 6,186,269 B1   US 6,432,308 B1 – Made in USA
New issued Patent10”inch Spherical Loudspeaker for Omnipresent Sound Reproduction
 
Our newest Patent: US 8,068,618 B2 Introducing NSR- Merkaball a 10”Spherical Loudspeakers. The Merkaball is the first of its kind to combine a vacuum compression propagation chamber incorporated with its spherical housing structure. This sophisticated method of technology design allows the Merkaball Loudspeaker to reproduce the entire audio spectrum over the 20~20000Hz range flawlessly.
 
Merkaball’s capability to reproduce low frequencies down to 32Hz all within a remarkable 50 cubic inches of internal volume not being limited to its size lets Merkaball loudspeakers takes the home audio industry, home theater and live performance music into a new realm forever.
 
All our patents cover special technology for omnipresent sound reproduction, and omnidirectional sound reproduction. We guarantee that what you will experience, you have never experienced before, in sound reproduction, from any traditional/conventional speaker systems. The Merkaball Loudspeaker it is indeed a marvel of its own creation. A spherical loudspeaker that reproduces sound the way the human ear perceives it in time and space. For its size, it is nothing short of astonishing.
​
Advantages
Traditional/conventional speaker systems require precise room placement, without obstruction within their wave path.  Merkaball and all of our OMNi Sound systems are designed to reproduce sound waves evenly throughout the spatial listening environment.  Even with obstructions, there are no adverse effects, making them most desirable.
 
Traditional/conventional speaker systems have a need for critical room placement configurations. With Merkaball Loudspeakers this is no longer a problem; the design orientation within the systems patented technology and configuration allows the Merkaballs to provide the listener excellent channel separation regardless of their listening position even with obstructions. Simply put there are no adverse effects.
 
Fact: sound being reproduced in an omnipresent manner is healthier and safer for your auditory system than conventional loudspeakers. In addition to home and pro audio use, there are many other applications for this type of sound reproduction such as music therapy, sound healing therapy, biofeedback, and psychoacoustics.
 
Humans respond differently to omnipresent sound verses traditional/conventional speaker systems.  Benefits of omnipresent sound have been demonstrated in premedical testing in cases of A.D.D., A.D.H.D., post closed head trauma, hypo and hyper acusis, Autism, stress disorders and in sleep disorders.
 
With Merkaballs what you hear is extraordinary sound clarity and realism with coherent, omnipresent sound being nearly flat across the 20~ 20000 Hz frequency range at +/- 1.5dB. Merkaball Loudspeakers combines their unique head assembly within their innovative patented technical design housing configuration of their two way speaker elements within the system configuration.  This results in the loudspeakers ability to reproduce the most important part of the audio spectrum which is speech intelligibility. Speech intelligibility is where most traditional/conventional speaker systems fall short. Speech intelligibility is score based referred to as STI or Speech Transmission Index) Merkaball Loudspeakers have a rating of 9 over the vocal range of 125 Hz to 8000Hz.
 
​What this means for the listener is they will hear and understand 99.999% of everything that is said throughout the audio spectrum.  Below, we have provided Merkaball’s complex data sheet with STI scoring to give you a better understanding of why you want Merkaball Loudspeakers over traditional/conventional speaker systems.
