The Amazon Fire TV Cube 2nd Generation combines a 4K streaming player, Alexa voice assistant, smart speaker, and basic home-theater control in one device. Released in 2019, it remains faster and more capable than many standard streaming sticks, although newer Fire TV models and competing streamers may offer better long-term value.
What Is the Amazon Fire TV Cube 2nd Generation?
The Amazon Fire TV Cube 2nd Generation is a hands-free streaming box designed to sit near your television. Unlike a Fire TV Stick, it includes a built-in speaker and microphones, allowing you to use Alexa without holding a remote or pressing a voice button.
You can say commands such as:
- “Alexa, open Netflix.”
- “Alexa, play The Boys.”
- “Alexa, pause.”
- “Alexa, switch to HDMI 1.”
- “Alexa, turn up the volume.”
It runs Amazon’s Fire TV operating system and supports popular services including Prime Video, Netflix, Disney+, Hulu, Max, YouTube, Apple TV, and many other apps. Availability can vary by country, and some services may require separate subscriptions.
The second-generation model uses a hexa-core processor, 2GB of RAM, and 16GB of internal storage. That gives it noticeably quicker navigation than entry-level streaming devices, especially when opening apps or moving through menus. It connects to your TV through HDMI and can use Wi-Fi or a wired Ethernet connection with the included Ethernet adapter.
Picture and Sound Quality
The Fire TV Cube 2nd Generation supports 4K Ultra HD streaming at up to 60 frames per second when your television, HDMI port, and streaming service support it. Compatible HDR formats include HDR10, HDR10+, Dolby Vision, and HLG.
That makes it a strong match for modern 4K televisions. Dolby Vision can improve contrast and color on compatible TVs, while HDR10+ can provide scene-by-scene brightness information on supported content. Not every movie or show uses these formats, so the actual improvement depends on both the title and your TV.
For audio, the Cube supports Dolby Atmos and other surround-sound formats when connected equipment and content are compatible. You will generally need an Atmos-capable soundbar or AV receiver, the correct HDMI connection, and a streaming subscription or title that offers Atmos audio.
The device itself has a small built-in speaker for Alexa responses and basic audio. It is not designed to replace a soundbar. You can also pair Bluetooth headphones, speakers, or other accessories, although Bluetooth audio can sometimes introduce a slight delay.
Setup and Everyday Use
Setup is straightforward, but you should plan the connections before plugging everything in. Connect the Cube’s HDMI output to an available HDMI port on your television, connect the power adapter, and follow the on-screen instructions. You will sign in with an Amazon account, connect to Wi-Fi, install updates, and choose the apps you want.
For the best performance, use a 5 GHz Wi-Fi network if your router is nearby. A wired Ethernet connection is preferable for a distant TV, congested wireless network, or high-bitrate 4K streaming. The Cube includes an Ethernet adapter, so you do not need to purchase a separate one for a basic wired setup.
The second-generation Cube can also control compatible televisions, soundbars, cable boxes, and other devices using HDMI-CEC, infrared commands, and supported network controls. Its HDMI input lets you pass a cable or satellite box’s video through the Cube, allowing Alexa commands to help change channels or switch inputs. However, it does not replace a cable box, DVR, or live-TV subscription.
During setup, enable HDMI-CEC on your TV if you want the Cube to control power and input switching. Manufacturers use different names for this feature, such as Anynet+, Bravia Sync, Simplink, or Viera Link.
Limitations and Buying Advice
The Amazon Fire TV Cube 2nd Generation is powerful, but it is not a perfect fit for everyone. Its hands-free microphones may respond to conversations or commands you did not intend to issue. You can disable the microphones using the physical microphone-off button, but doing so also prevents hands-free Alexa control.
Amazon’s Fire TV interface prominently features recommended content and sponsored promotions. This is normal for the platform, but viewers who prefer a simpler or less commercial home screen may prefer Apple TV 4K, Roku, or Google TV.
The Cube also depends heavily on Amazon’s software ecosystem. App support is broad, but the interface and available features can change through updates. Storage is limited to 16GB, and some of that space is used by the operating system. Most users will have enough room for normal apps, but large game libraries can consume it quickly.
Because the second-generation model is older, check the price carefully before buying. A discounted unit can be a good choice for a 4K TV, especially if you already use Alexa devices. At a similar price, however, a newer streaming box may provide a longer support lifespan, faster wireless standards, or newer processor features.
Amazon Fire TV Cube 2nd Generation FAQ
Does the Amazon Fire TV Cube 2nd Generation support 4K?
Yes. It supports 4K Ultra HD streaming at up to 60 frames per second, along with HDR10, HDR10+, Dolby Vision, and HLG. Your TV, HDMI connection, internet speed, and streaming service must also support the desired format.
Can the Fire TV Cube control a cable box?
Yes, in compatible setups. The Cube can use its HDMI input, infrared control, and HDMI-CEC features to help switch inputs and control certain cable or satellite boxes. It does not provide cable service or record programs by itself.
Is the second-generation Fire TV Cube still worth buying?
It can be worthwhile when heavily discounted and when you want hands-free Alexa control, fast Fire TV performance, 4K HDR, and home-theater device control. Avoid paying a premium for it over newer streaming hardware, particularly if you want the latest Wi-Fi features or the longest expected software support.
The Amazon Fire TV Cube 2nd Generation remains a capable all-in-one streaming device for Alexa households and 4K TV owners. Its fast interface, broad HDR support, Dolby Atmos compatibility, and HDMI control features make it more versatile than a basic streaming stick. Buy it at a sensible price, connect it through Ethernet when practical, and review its privacy and voice-control settings during setup.
