A:AnswerHi Reggae. Echo Sub must be paired with a compatible Echo device. Currently, stereo pairing, speaker groups, and multi-room music only support music playback over your wireless network, and do not support Bluetooth, 3.5mm AUX in, or TV/video connections. I hope I have answered your question. Have a nice day.
A:AnswerThe echo sub can only work with compatible echo devices. Ours is paired with an echo studio that also has great sound or I can be paired with any othe compatible echo device.
A:AnswerHi Kack,
The low frequency response of this Echo Sub is 30Hz (-6dB). The crossover frequency is 50 Hz - 200 Hz adaptive low-pass filter.
Hope that helps!
