The Tri-Band Wireless Audio Adapter is the newest Wireless transmitter from SVS, for those who would like to place their subwoofers (or Speakers) in the optimal location in their room but do not want to extend long meters of cables. It's 200$ USD per Transmitter and Reciever but SVS support has disclosed with me that they've started to sell them individually as well.
The previous iteration, the Soundpath Wireless Audio Adapter was quite successful and measured decently by Amir here. However, according to other users, it's not great in areas with HEAVY interference, which was also disclosed by SVS as well.
I live in an apartment in a gigantic building with possibly tens of thousands of devices using WiFi, so i was very hesitant to use such products. However, with the release of the Tri-Band version I felt much more confident and I took the plunge!
Once installed, it auto-switches between the 2.4 GHz, 5.2 GHz, and 5.8 GHz wireless bands for uninterrupted audio signal transfer. (Allegedly) Impervious to interference from Bluetooth, Wi-Fi routers, wireless security systems, cameras, and other wireless devices.
However there is no Free luncheon, this device introduces ~19.25 ms of delay (advertised and confirmed by measurements), compared to the 14ms of delay for the previous iteration.
What's in the Box?
Two (Mono?) RCA Cables
Two power adapters and two USB cables to power the devices
One transmitter and one receiver
two Velcro stickers to stick the Tri-Band to a surface if you would like
Installation
It's pretty much plug and play as the transmitter and the receiver are paired before they're delivered to you, as soon as the two devices are powered the link is established.
Measurements
To measure the performance I used equipment (DAC and ADC) that I own and has been measured on by Amir for reference, this is not perfect, but i have enough resolution to clear out the entire CD format (~96dB SINAD), the MiniDSP was also used to voltage/volume match the two inputs.
Claim #1: Tri-Band adds only ~19ms of latency.
True. I measured the latency by using the 'Tri-Band free output as the Reference output and selecting 'loopback as acoustic timing reference' in REW
Claim #2: SoundPath provides “full-range wireless connectivity,” possessing the ability to transmit frequencies between 6Hz and 22kHz +/-0.5dB.
True. I wouldn't lose sleep over the tiny difference in high frequency roll-off in the SPL sweep.
Claim #3: THD+N (SINAD) is -70dB (10Hz – 20kHz)
True. I'm infact getting 75 dB SINAD which is utterly and completely transparent for subwoofer use.
Claim #4: S/N: +105dB (10Hz - 20kHz)
Probably. I'm limited by the MiniDSP in that regard, but it shows ~6 dB higher noise than the Qudelix on its own. Which checks out. You're free to interpret this however you want.
Claim #5: The Tri-Band is quite impervious to Wifi interference
True. Playback has been fairly smooth and uninterrupted (even at full bandwidth), my subwoofers are not turning on in the middle night and causing mini explosotions. Considering that my apartement is wifi hell, that's pretty good.
Conclusions
Seems like a quite well engineered product, I would recommend it to anyone struggling with subwoofer placement because they don't want to extend cables, even in very dense apartment complexes and intense Wifi interference.
