Do the Kanto YUP4 speakers need an amplifier?

Yes. They are passive speakers with binding posts only, so you need an amp or receiver rated for 4-ohm loads. Plan on roughly 20 to 70 watts per channel.

Do they have Bluetooth or a built-in amp?

No. There is no Bluetooth, no volume control and no digital input. All connections go through the binding post pair on each speaker.

How low does the bass go?

Kanto rates them from 60 Hz to 20 kHz. That covers most music, but for movie effects or deep electronic bass, add a subwoofer.

Can I mount them on stands or a wall?

There is a 1/4-20 threaded hole in the bottom of each cabinet for bolting to stands. Keep some space behind the rear port for clean bass.

Is $229.99 a good price?

That is the best new price across 6 stores as of November 6, 2026, at Best Buy. Check the price history before buying to see whether it has sold lower.

What comes in the box?

Our take on the Kanto YUP4 Passive Bookshelf Speakers

The Kanto YUP4 is a passive pair of 4-inch bookshelf speakers, so you supply the amplifier. Each cabinet pairs a woven Kevlar woofer with a silk dome tweeter and a rear-firing port, rated 60 Hz to 20 kHz at 4 ohms and 86 dB sensitivity. A threaded 1/4-20 hole in the base lets you bolt them to stands. The best new price is $229.99 at Best Buy as of November 6, 2026, with 6 stores listing them new.
