Does the Supersonic SC-1421SB have a subwoofer?

No. It is a 2.0-channel bar with four built-in 2.25-inch drivers and no separate subwoofer, so low bass is modest.

Can I stream music to it from my phone?

Yes. It has a built-in Bluetooth 5.0 receiver with a rated range of about 10 meters for pairing with phones, tablets and other Bluetooth devices.

What can I connect to it?

It offers optical S/PDIF, HDMI, RCA line-in, a 3.5mm aux jack and a headphone jack. There is one HDMI port and no pass-through.

Does it support HDMI ARC?

The connections list HDMI and ARC, but HDMI pass-through is not supported. Check your TV's audio output settings before relying on a single-cable setup.

What size TV does it suit?

The bar is about 32 inches wide and is described as matching TVs from 32 to 48 inches. Its low profile of roughly 3.9 inches tall helps it sit under most screens.

Does it come with a remote?

Yes. A remote control is included, and the bar has a front LED display for settings.

Our take on the SUPERSONIC SC-1421SB

The Supersonic SC-1421SB is a 2.0-channel soundbar with four built-in 2.25-inch drivers rated at 60W RMS. It connects over Bluetooth 5.0, optical, HDMI, RCA line-in and a 3.5mm jack, and comes with a remote and an LED display. It has no subwoofer, no simulated surround and no HDMI pass-through, so it is a basic stereo upgrade for a small or mid-size TV rather than a home-theater centerpiece. Shoppers wanting deeper bass or room calibration should look at 2.1 soundbars with a separate subwoofer.
