The Amazon Fire TV Cube 2nd Generation combines a 4K streaming player, Alexa smart speaker, and universal remote-control hub in one device. It remains a capable option for streaming Netflix, Prime Video, Disney+, YouTube, and live TV services, especially for households that want hands-free voice control and fast performance.
What Is the Amazon Fire TV Cube 2nd Generation?
Released in 2019, the Amazon Fire TV Cube 2nd Generation is a cube-shaped streaming device that connects to your television through HDMI. Unlike a standard Fire TV Stick, it does not need to be hidden behind the TV. Its built-in microphones and speaker allow you to use Alexa without picking up a remote.
The Cube can launch apps, search for movies, control playback, adjust volume, and operate compatible equipment using voice commands. With the right setup, Alexa can also switch inputs and control devices such as a cable box, soundbar, Blu-ray player, or AV receiver.
It includes 16GB of internal storage, 2GB of RAM, dual-band Wi-Fi, an Ethernet connection, HDMI output, and an HDMI input for compatible cable or satellite equipment. The HDMI input does not turn the Cube into a DVR or TV tuner; it simply lets the Cube control and pass through another video source.
Key Features and Picture Quality
The Amazon Fire TV Cube 2nd Generation supports 4K Ultra HD streaming at up to 60 frames per second. It also supports several major HDR formats:
- Dolby Vision
- HDR10 and HDR10+
- HLG
- Dolby Atmos audio, where supported
Your television, audio system, subscription, and specific content must all support these formats. For example, a Dolby Vision television will not make every title appear in Dolby Vision. The streaming app and movie or show must offer it as well.
The Cube’s processor is considerably faster than the processors found in many older Fire TV Sticks. Menus generally open quickly, apps respond well, and switching between streaming services is smooth. The 16GB storage is also useful because many streaming devices provide less space for apps.
Alexa control is the main feature that separates the Cube from other Fire TV products. You can say commands such as “Alexa, open Netflix,” “pause,” “show me action movies,” or “turn off the TV.” It can also control compatible smart lights, thermostats, plugs, and cameras.
Setting Up the Amazon Fire TV Cube 2nd Generation
Setup is straightforward, but voice-controlled equipment requires a few extra steps.
- Connect the Cube to your television’s HDMI port.
- Plug in the included power adapter.
- Connect to Wi-Fi or use Ethernet for a more stable connection.
- Sign in with your Amazon account.
- Download or update your preferred streaming apps.
- Follow the on-screen instructions to configure your TV, soundbar, and other devices.
For reliable hands-free control, place the Cube in an open area near the television. Avoid putting it inside a cabinet or directly next to a loud speaker. The built-in microphones need to hear Alexa clearly.
During setup, the Cube tests HDMI-CEC and infrared control. HDMI-CEC allows compatible devices to respond through the HDMI connection, while infrared control uses the Cube’s built-in IR emitters. If your soundbar or cable box does not respond correctly, try the included IR extender and place it in front of the equipment’s infrared sensor.
A wired Ethernet connection is worth considering if your Wi-Fi signal is weak or your home network is crowded. It can reduce buffering, although your internet speed and streaming service quality still matter.
Everyday Performance and Limitations
The Amazon Fire TV Cube 2nd Generation is quick enough for everyday 4K streaming, app switching, and voice searches. Its voice search is particularly convenient when typing with a remote would be slow. Alexa can also search across supported apps, although results and playback options vary by service.
The Fire TV interface includes Amazon promotions and recommended content. Some users appreciate the integrated discovery features, while others may find the home screen busy. You can organize apps and move frequently used services toward the front, but you cannot completely remove all sponsored content.
The included remote provides traditional buttons for navigation, playback, volume, and power. Voice control is helpful, but it is not always perfect. Similar titles, privacy settings, inconsistent app support, or an incorrectly configured device can produce unexpected results.
The Cube also requires a constant power connection. Unlike a Fire TV Stick, it is not powered directly from the television’s USB port. Bluetooth accessories, such as headphones or game controllers, may be paired, but it is not designed to replace a dedicated gaming console.
Is It Still Worth Buying?
The Amazon Fire TV Cube 2nd Generation can still be a good choice if you find it at a reasonable price and want fast streaming with Alexa built in. It is especially useful for people who have multiple entertainment devices and want one box to manage them.
However, check the price against newer Fire TV models before buying. A newer device may offer a longer support lifespan, updated wireless technology, or improved processing. The second-generation Cube is also larger and more expensive than a basic streaming stick.
Buyers should confirm that the device is sold by a trustworthy retailer and is compatible with their television and sound system. Used units may still work well, but check that the remote, power adapter, HDMI cable, and any needed IR extender are included. Also inspect the device for overheating, account-lock issues, or damage.
Frequently Asked Questions
Does the Amazon Fire TV Cube 2nd Generation require Alexa?
No. You can use the included remote and navigate the Fire TV interface normally. Alexa is integrated into the device, but hands-free voice control can be disabled through the settings if preferred.
Can it control a cable box?
Yes, in many cases. The Cube can control compatible cable boxes through HDMI-CEC or infrared commands. It does not replace your cable subscription, record programs, or decode unsupported services. Compatibility depends on the cable box model and setup.
Does it support Dolby Vision and Dolby Atmos?
Yes, the second-generation Cube supports Dolby Vision and Dolby Atmos when the television, sound system, app, subscription, and content all support them. Set your TV and receiver to compatible HDMI and audio modes for the best results.
The Amazon Fire TV Cube 2nd Generation remains a powerful all-in-one streaming device for households that value 4K HDR quality, quick menus, and hands-free Alexa control. It is most worthwhile when discounted, properly configured, and paired with compatible home theater equipment.
