One of the problems with setting up a home theater system is all the wires needed to connect the speakers. However, WiSA Technology offers a wireless connection solution for all your speakers in a home theater setup, greatly reducing wire clutter. 

WiSA Overview

WiSA (Wireless Speaker and Audio Association) was formed in 2011 as a trade organization supported by member companies. The organization develops and coordinates technology, implementation standards, sales training, and promotion of wireless home theater audio products, which now include TVs, soundbars, and speakers. 

WiSA tests and certifies products developed by its member brands to ensure consistent standards for wireless high-resolution, multi-channel, low latency, compatibility, robustness, and ease of use so that products carrying the WiSA label work seamlessly together. 

Member Brands include Bang & Olufsen, Klipsch, Harman Kardon, Axiim, Platin, Enclave Audio, Sound United, and more… WiSA also provides retailer support

WiSA HT (Home Theater)

The core WiSA category is labeled WiSA HT, which employs an external transmitter (or hub) that may connect to a TV via HDMI-ARC/eARC, Digital Optical, or USB Connection. 

The transmitter may come as part of a WiSA-certified wireless home theater speaker package or come as a separate unit (such as the WiSA SoundSend$179 at Amazon) that can be used with any brand of WiSA-certified speakers.

WiSA HT supports up to 8 channels of audio (for Dolby Atmos which means up to a 5.1.2 channel setup) and operates in the 5Ghz transmission band. 

An example of WiSA HT implementation is the recently released Platin Audio Monaco 5.1.2 WiSA Home Theater System ($1,499.00). The system comes packaged with a WiSA SoundSend transmitter and a Dolby Atmos speaker system.

Also, both Hisense and LG are implementing WiSA HT on select TVs via WiSA SoundSend certification.  

However, in a strategic move WiSA has announced two additional technology options that it will be licensing to interested product brands.

WiSA DS (Discrete System)

Announced earlier in 2022, WiSA has decided to target this technology for use with Soundbars. WiSA DS gives soundbar makers the ability to make soundbars that incorporate WiSA technology for easy implementation of wireless surround speakers and subwoofers. 

This can take the form of a complete package that comes with the soundbar, wireless speakers, or subwoofer, or just the soundbar with the option for adding wireless surround speakers and/or subwoofer at a later date with minimal setup required.

DS supports up to 8 channels of audio (for Dolby Atmos which means up to a 5.1.2 channel setup) and operates in the 2.4Ghz transmission band. 

The soundbar connects to the TV via HDMI-ARC or eARC, or another designated audio connection. With the soundbar’s WiSA DS capabilities built-in, it can, in turn, send surround sound and bass audio out to wireless external speakers and/or subwoofer.

The soundbar will detect the presence of the speakers and/or subwoofer and determine their location and distance. The only wired requirement is the wireless speakers and subwoofer do need to be plugged into power. 

WiSA E (Embedded)

This program is designed for use with TVs. WiSA E is even more convenient than using a WiSA DS soundbar as WiSA E technology can be embedded in the TV. 

This means that no external soundbar or AV receiver needs to be physically connected to the TV via HDMI-ARC/eARC or other wired audio connection. You just purchase a WiSA-certified speaker system of any brand, plug them into power and the TV will automatically detect their presence, location, and distance and make the needed adjustments for audio enjoyment. 

WiSA E supports up to 10 audio channels (for Dolby Atmos which means up to 5.1.4 channel setup) and operates on the 5Ghz transmission band.  

Tip: WiSA DS and WiSA E both support Dolby Atmos and other Spatial Audio formats as determined by the product maker. 

WiSA DS and E Availability Timeline

WiSA is currently providing limited demonstrations to investors and partners but is expected to have fuller demos at the 2023 CES in January, with products expected to show up on store shelves before the end of that year. 

We are definitely looking forward to seeing, hearing, and reviewing some of these forthcoming WiSA DS and E products. 

Will this make traditional wired home theater systems redundant in the near future?

It could certainly be a positive move in that direction.
