About the Kanto YU4

Versatile powered stereo speakers

I'll admit, the first thing I noticed about the Kanto YU4 speakers is how beautiful they look. But of course they're built to sound sweet, too, with a pair of 4" Kevlar® woofers and 1" silk dome tweeters, powered by 70 watts of amplification built into the left-hand speaker.
Kanto YU4

Kanto YU4 speakers feature a built-in phono preamp, so you can enjoy records without a receiver or power amplifier (stands not included).

Versatile powered stereo speakers

I'll admit, the first thing I noticed about the Kanto YU4 speakers is how beautiful they look. But of course they're built to sound sweet, too, with a pair of 4" Kevlar® woofers and 1" silk dome tweeters, powered by 70 watts of amplification built into the left-hand speaker.

I'd recommend adding a pair of Kanto S4 stands (pictured on the right). They elevate the speakers by 16 degrees for optimum performance.

Handy wired connections

I love being able to plug all of my gear into my powered speakers, and the YU4 delivers on that score. There are two Toslink digital optical inputs on the back — useful for connecting a CD player and your TV. The stereo analog RCA input is ready for a turntable or other analog source, and there's a 3.5mm aux input for making a quick connection with a mobile device.

And if you want — or even need — a little more bass, there's a subwoofer output on the back.

My hands-on experience with Kanto YU4 bookshelf speakers

I got a chance to audition a pair of Gloss Black Kanto YU4 speakers at home, and I really enjoyed them. I decided to use them in my bedroom, where the 4" drivers could really fill the available space. I thought they sounded nice when I played my "speaker test" playlist the first time, but each track really came alive when I added a matching Kanto SUB6 to round out the low end. Jaco Pastorius and James Blake, in particular, benefited from the punchy, musical bass.

When I'm in my room, I watch Netflix and movies more often than I listen to music, and the YU4s had me covered there, too. I used the optical input on the back to connect my TV, and everything got better — I could hear dialogue better, soundtracks were more present, and the sub made sound effects more immersive.

If you're looking to rock out in a larger family room or living room, the YU6 with a SUB8 will do a better job, but this setup looks elegant and sounds great in a small- to medium-sized space.


Vinyl is making a comeback, but for some folks it can be difficult to find room for a receiver or amplifier. The YU4 speakers have their own built-in amp and switchable phono preamplifier, so you can directly connect a turntable and save space. 

If your turntable has its own preamp built in, set the switch to "Line" and you're ready to go. If not, the "Phono" setting engages the speakers' built-in preamp.

Smart power saving

You can engage the speakers' standby mode, and they'll remain active in low-power mode waiting for input. When you start playing music again, the system automatically returns to full power and starts to play.

Product Research


Two-Way Driver Design: The Kanto YU4 powered speaker system features a two-way driver design with a 1" silk dome tweeter and 4" kevlar cone woofer for clear high and detailed midrange/midbass frequencies.

  • 1" Silk Dome Tweeter: The 1" tweeter is made from silk to deliver a high-frequency range that's bright and refined. The tweeter's dome shape improves sound dispersion to ensure your ears capture every sound, regardless of where you are in the room.
  • 4" Kevlar Cone Woofer: The 4" woofer cone is made of a kevlar material and features a rubber surround for long-lasting performance. The woofer provides surprisingly controlled and accurate low frequency response.

Class D Amplifier: The 1" tweeter and 4" woofer are powered by a built-in 35 watt (RMS) / 70 watt (Peak) x 2 channel amplifier for dynamic sound reproduction. The built-in amplifier is located in the YU4's "Left" powered speaker. The binding-post output terminals on back of the "Left" powered speaker and the included 16' speaker wire provide connection to the "Right" passive speaker's binding-post input terminals.

Note: The included 16' speaker wire can be replaced with a long speaker wire (sold separately - see Accessories Tab), if your setup requires that the speaker's be placed further apart.

Bass Reflex Cabinet: The Kanto YU4 powered speaker system utilizes a bass reflex enclosure design with a rear-firing port for greater efficiency and bigger bass response. The speaker cabinet is available in black, white, walnut, and bamboo finishes.

Note: The Kanto YU4 powered speaker system does not come with grilles.

24-Bit/96kHz DAC: The Kanto YU4 powered speaker system utilizes a 24-bit/96kHz resolution DAC (digital-to-analog converter) for high-quality sound reproduction.

Bluetooth Audio Streaming: The Kanto YU4 offers built-in Bluetooth 4.0 with support for wireless audio streaming (A2DP) and control (AVRCP). You'll be able to wirelessly stream your music libraries, music apps, and other audio content on your Bluetooth source device (such as your smartphone, tablet, laptop, or computer) to the YU4 speaker system. You can pair multiple Bluetooth source devices with the YU4 powered speaker system, but only one device can be connected and used for playback at a time.

  • Music Codecs: In addition to supporting the standard Bluetooth SBC codec, the YU4 system offers support for Qualcomm's aptX codec. Qualcomm's aptX codec provides even better sound quality with lossless, "CD-quality" (16-bit/44.1kHz) streaming for aptX-compatible source devices, such as many Android smartphones and tablet with OS 4.0 or newer.
  • Playback Control: You'll also be able to control basic playback functions (such as Play/Pause & Previous/Next Track) from the included remote control. Advanced music playback and song/artist display will still be done from your Bluetooth source device.

Note: The Kanto YU4 powered speaker system does not support Bluetooth hands-free communication for making and answering phone calls.

Line or Phono Input: There is a 3.5mm Aux input (located on the "Left" powered speaker) for connecting a portable digital audio player with a headphone jack output. The YU4 also comes equipped with a stereo audio RCA input (located on the "Left" powered speaker) and built-in phono preamp, allowing you to connect a line-level source or phono turntable. You can toggle between line-level and phono with a simple flip of a switch that is located on the rear-panel of the "Left" powered speaker. In addition, there is a ground-terminal to reduce noise.

Optical Digital Inputs: The YU4 is equipped with two optical (toslink) digital audio inputs (located on the "Left" powered speaker) for connection to your TV, satellite/cable box, Blu-ray player, or game console. The optical digital inputs support 2ch PCM only, up to 24-bit/96kHz (not compatible with Dolby Digital/DTS).

USB Charging Port: Use YU4's USB charging port (located on the "Left" powered speaker) to conveniently power and charge your smartphone or tablet device. The USB charging port is rated at 5V/1A.

Note: This USB port does not support audio playback.

Sub Out: The Kanto YU4 is equipped with a mono-RCA subwoofer output (located on the "Left" powered speaker) for connecting a powered subwoofer (sold separately - see Accessories Tab) to add deep, low bass to the speaker system. The YU4's sub output is full-range, so you'll need a powered subwoofer with a built-in low-pass crossover.

Simple Control: The included IR remote control provides wireless operation of the Kanto YU4 speaker system (the IR receiver is located on the "Left" powered speaker). From the wireless remote you can control Power On/Off, Source Selection, Volume Up/Down, Mute, Bass/Treble, Balance, Play/Pause, and Previous/Next Track. There is also a rotary Volume/Source control knob on the front-panel and a Power on/off switch on the back-panel of the "Left" powered speaker.

Mounting & Placement Options: The YU4 powered speaker system is designed for either bookshelf or stand mounting (see Accessories Tab for desktop and floor stands - sold separaetely). The speakers come with self-adhesive rubber feet to protect your furniture (the feet add approximately 0.125" to the overall height of the speakers). The space between the two speakers and the distance from the listener is important. If the speakers are positioned too close or too far apart, stereo imaging will not be fully developed. Room characteristics and positioning also have a profound effect on the performance of the speakers, so time and effort devoted to achieving the optimum positions will be rewarded.

  • YU4 is designed to perform optimally at ear level and positioned at least 8" from the rear wall in an average listening room. However, it may not be possible to install the speakers in this position since rooms vary in shape, size, and furnishing. A certain amount of experimentation may be necessary to determine the most suitable position.
  • Moving the speakers very close to the rear wall will enhance the bass frequencies, but will tend to reduce soundstage depth, while moving the speakers away from the rear wall will tend to have the opposite effect. Avoid positioning the speakers close to or in the corners of the room, as this will excite undesirable room coupling in the low and middle frequencies. If the width of the rear wall is limited then toe-in the speakers slightly to reduce reflections.

Note: The Kanto YU4 does not offer brackets, threaded inserts, or key-hole slots to wall-mount the speakers.

Power Requirements: The Kanto YU4's "Left" powered speaker includes a detachable 6' AC power cord that will need to be plugged into an AC power outlet or surge protector (sold separately - see Accessories Tab). The "Right" passive speaker does not require AC power.

Note: The Kanto YU4 speaker system is not battery powered.

Auto Power On/Off: The Kanto YU4 speaker system features Auto Power On and Off functions to save power. When no audio signal has been detected for 15 minutes, the YU4 system will put itself into Standby (Off) mode. If the audio signal returns via the same input that the YU4 was playing when it entered standby, the system will wake up and resume playing. It can also be woken up manually by pressing the "Power" button on the remote or pressing the rotary control knob on the front-panel of the "Left" powered speaker.

Note: The Automatic Power On function will not work if the YU4 system is manually switched to Standby (Off) mode using the remote or control knob.

Does anyone know if these are compatible with LG Sound Sync? My intention is to use these connected to my LG C1 OLED TV with an optical cable, but I would want the TV remote to control the sound volume.
brian  Dec 30, 2022
1 answer
Greetings BrianB, and thank you for your question. Word from LG is to use Sound Sync, both the TV and the speaker/sound bar need to be LG devices. You can still connect these Kantos via optical cable but you would have to use the Kano remote as well.
hogan  Dec 30, 2022 (Staff)
My Kanto YU4s came with a 3.5mm balanced (4 pole) cable to use on the Aux 3.5mm input. Is it safe to plug the other end of that balanced cable into a unbalanced 3.5mm (3 pole) output of another device? I believe that is is okay, but going the other direction is bad. Please advise........

How do you connect a Kanto Sub8 to a Kanto YU4? There is only one sub out port on the YU4, but two inputs on the sub8? What kind of split cable/adapter is required? Does it come with the YU4 or Sub8?
will  Nov 18, 2023
1 answer
You will only need to connect to one of the inputs (either L or R) in this situation. You'll use a mono-RCA cable for the job. A 10-foot mono-RCA cable is included with the SUB8.

I am looking to get better sound from our Samsung 65" TV, hooked up optically, would these work? I am looking for better sound since I use hearing aids.
jeff  May 15, 2023

We would definitely expect YU4 to sound better than most built-in TV speakers these days. They would work nicely for your application.
zachary  May 15, 2023 (Staff)
Is anyone using a sub with these? If so do you need a high / low pas filter? I will need a sub.
mark  Apr 21, 2023
1 answer
Greetings Mark, and thank you for your question. Many will also use a subwoofer with the YU4's, but by themselves, the bass response is decent for their size. Kanto recommends using a subwoofer with a built in crossover, but most have those anyway.
hogan  Apr 21, 2023 (Staff)
I have an older LG subwoofer. Can I connect it to the YU 4?
gregory  Dec 18, 2020
3 answers
Not sure what inputs you have on your Sub, the YU4 has a single RCA line, I had to buy an RCA Y cable to line in my sub.
james  Dec 18, 2020
The YU4 has a subwoofer out connection. Consequently, I do believe that you can connect it to a subwoofer. I do not know if you can modify the crossover on the YU4 to send lower frequencies solely to the subwoofer.
joseph  Dec 18, 2020
I am not familiar with the connector on the LG. However, the YU4 accepts a standard RCA plug. If the LG is not an RCA plug I am sure you can find an adapter
dale  Dec 18, 2020
I want to use these with the optical output on my PC. Does that mean I will need to set the switch on the back of the speaker to Phono? Otherwise which is appropriate?
storm  Dec 25, 2023
1 answer
The analog audio input switch would not come into play at all using the optical connection, Storm. You would only need to select an option on that switch if you were connecting a turntable or other line-level input (like a CD player). I hope this helps!
bo  Dec 27, 2023 (Staff)
If I want to place these speakers (with the optional angled stands) on the same table as my turntable, what are some good options to isolate everything?
michael  Aug 11, 2022
1 answer
For help with selecting an isolation solution, please give us a call at 1-800-324-9695. There are a few ways that we could approach isolating these speakers, but picking the best options may require a bit of discussion.
zachary  Aug 11, 2022 (Staff)
Would this work well/be ideal for the Pro-Ject Debut Carbon EVO record player? If not, what do y'all recommend?

In my opinion, light walnut (regardless of the manufacturer) clashes with many audio components. For that reason I no longer acquire light walnut as my choice. However, this is a personal decision. Kanto makes great speakers as well as other components and I have several of their products. I would say the Kanto speakers you are interested in would look great if they are the only component with your turnable.
michael  Oct 11, 2021
Couldn't say yes or no; the Kanto YU4 speakers are used for my computer speakers and I took advice from another Crutchfield customer who suggested to pair them with a Jamo subwoofer. So, I have never used them with any record player. I would contact Crutchfield Technical support on this one.
