Sontia: Phase Stable Technology

[TitaniumTroy]

Here is a integrated system approach to improving speaker performance, that starts with product development. So it is individually tailored or customized to each system it used in, and does use some active EQ processing. A much wider listening area is claimed, along with correcting phase, time and frequency distortions, LG is using it in a soundbar, THX has also signed on.

In the Home Theatre Geeks video, the interviewer mentioned he did not hear that much difference at CES with a very high end system. The caveat being that they switched from using expensive high wattage Aragon amps to using Sontia's 25watt D class amp, via a monitor type speaker. However in the LG soundbar demo the difference was a lot. The guest mentioned that their system when used with something Audessy room correction software the sum is greater than the parts.

Blue Tooth devices, headphone's, jambox's etc... will be using this technology as they are ready using some DSP and because they are using active amplification. Also I saw a graph in the video that show a vastly improved impulse response test using technology.

Re: Sontia: Stable Phase Technology

There have been dozens of phase correction technologies introduced over the years, the most memorable being the 1990s Digital Linear Phase speakers which came with a processor/amp which make for perfect phase acoustic output. They were most impressive. before that I remember passive all pass crossover filters designed solely to correct for the most extreme phase issues in a speaker system.

Today nearly all of the multi-amp active speakers in the PA and Studio markets use digital crossovers with DSP for time alignment, crossover, and EQ. Some even address phase when the designer feels can significantly improve the sound quality since the OEM DSP modules now have more than enough processing power and algorithms to do that work.

This approach from Sontia is interesting, but it is not unique. It is different in that they are marketing it separately, much like Dolby, DBX and DTS have done in the past. Anything that can improve the sound quality of the crappy budget systems I have to listen to when away from home is a good thing.

Thanks for the input Flint.
