Fosi Audio BT20A TPA3116 Class D amp, Sonos Sub mini subwoofer, Ray hit lowest ever prices

Recently, we covered a couple of great deals on speakers from renowned manufacturers Edifier and Klipsch. While the Edifier deals have mostly expired, the one on the Klipsch is still live and hence you can check it out here as it's selling for its lowest-ever price of just $297.

However while those were active speakers and already came with an amplifier integrated to power the system, it is possible that you may have some passive speakers in mind or have some lying around and that you'd like to play. If you are in the market for such a thing, Fosi Audio is currently selling its BT20A amplifier for the lowest price ever (buying link below).

Fosi Audio BT20A

The BT20A is a Class-D amplifier and as such it is quite efficient which is how Fosi Audio has been able to pack so much power into such a small size. Speaking of power, the amp is powered by Texas Instruments (TI)'s TPA3116D2.

The specifications of the Fosi Audio BT20A are given below:

  • Power supply range:12v-24v

  • Frequency Range: 20Hz - 50kHz (±2 dB)

  • SNR ≥ 98dB

  • Input sensitivity ≤ 280mV

  • Bluetooth transmission distance: 28ft

  • Terminating impedance: 2Ohm - 8Ohm

  • Output power: 100W + 100W

    • 100W X 2 (4 ohms, 20 Hz - 20 kHz, 0.04% THD), comes with a 24V power supply.
      If your usage scenario is smaller, it can also drive larger speakers, such as those rated at 280 watts (8 ohms) and 320 watts (4 ohms). Please note that this is applicable only for passive speakers.

  • Input mode: Bluetooth and Analog

  • Bluetooth chip: ATS2853
