The BX-25D is a 25-Watt Dante/AES67 4.5" woofer speaker which allows lower fuller frequencies to be added to any room. Primarily designed for the Aurora ReAX Room to complement the RXT-4D/DV (4" Touch Controller with Dante/AES67 Beamforming Microphone & Speaker). The small form factor and light weight allows it to be mounted under the table with the included mounting brackets or just about anywhere. The mounting bracket has rubber grommets built in to help isolate vibration into the table. It also features an OLED for IP Address and other status information for better setup and serviceability.
