Do these need an amplifier?

No. They are active speakers with built-in amplification, so you plug in a source and play. You do not need a separate receiver or amp.

What can I connect to them?

They offer Bluetooth and wired inputs, so phones, laptops, TVs and turntables with a suitable output can connect. Check that your device's output matches the speaker's inputs.

Is there a subwoofer output?

No subwoofer output is listed. Bass comes from the drivers in the cabinet, so deep low-end from a separate sub is not an option here.

How do I control volume and inputs?

Use the knob on the speaker or the included remote. The remote also switches inputs and changes tracks.

Will they work for a TV setup?

They can, if your TV has a compatible wired or Bluetooth output. There is no HDMI ARC, so TV volume control over HDMI is not available.

Our take on the KFFKFF Powered Bookshelf Speakers

The KFFKFF Powered Bookshelf Speakers are active two-way speakers in an MDF cabinet, with built-in amplification rated at 120W and a 65Hz–20kHz range at 8Ω. They connect over Bluetooth and wired inputs and come with a remote plus a front knob for volume and source switching. They suit a desk, small room or TV setup where you want stereo sound without a separate amplifier. Against mainstream powered bookshelf pairs, the feature set is basic: no HDMI ARC, no app EQ and no subwoofer output are listed, so check the inputs you need before buying.

About the KFFKFF Powered Bookshelf Speakers

These powered bookshelf speakers are an active stereo pair with a 5.25-inch woofer and a 1-inch tweeter in each cabinet. The cabinets are made of MDF wood, which is meant to improve audio quality and minimize vibrations. The finish is black.

They connect by Bluetooth, coaxial, optical, USB audio and RCA, and they also have a subwoofer connection. That lets them work with smartphones, computers, tablets, TVs, amplifiers, gaming consoles, turntables and active subwoofers.

A knob on the speaker controls volume and source. The remote control adjusts volume, changes tracks and switches inputs.
