Our take on the Definitive Technology Cube

by Ralph Graves
Definitive Technology

Innovative design, innovative sound

There's nothing ordinary about the Definitive Technology Cube. This portable Bluetooth speaker system's attractive, minimalist design suits just about any décor. And its compact shape lets it fit easily into the corner of a countertop or bookshelf. Best of all, it treats you to sound that's surprisingly rich and involving for a speaker so compact.

Definitive Technology Cube

The Cube features a total of six built-in speakers in a “Tri-Polar” configuration. The left and right side each feature a pair of 1-1/4" mid/high-frequency drivers, set at a 90-degree angle to one another to create a wide soundfield and increase the sense of stereo separation. An upward-firing 1-1/4" driver and 5-1/4" woofer add a sense of height and reinforce the bass frequencies. All the drivers together — supported by built-in amplifiers and advanced digital processing — deliver full, spacious stereo sound that most compact powered speakers can only dream of.

High-quality Bluetooth audio

The Cube uses aptX® audio coding, an advanced form of Bluetooth that allows higher-fidelity sound with compatible Bluetooth devices. It's backwards-compatible with earlier forms of Bluetooth, too. So you can wirelessly stream music from just about any smartphone, tablet, laptop, or other portable device and still enjoy outstanding sound.

Play it anywhere indoors or out

You can power the Cube with regular household AC, but this speaker also has a built-in lithium ion battery. When you want to take the party outside or into another room, just unplug the power cord and carry the Cube with you. The system can deliver up to 8 hours of high-fidelity sound, fully charged.

Features

Cube Design: Definitive Technology's Cube tabletop Bluetooth loudspeaker makes a strong visual impression with its bold, minimalist compact shape that easily tucks into the corner of your kitchen counter, bookshelf, or credenza.

Tri-Polar Speaker Technology: Combining built-in amplifiers, digital signal processing, bass-reflex enclosure, and speaker components in a "Tri-Polar" configuration, the Cube is able to produce impressive bass and spacious imaging. Tri-polar Technology employs speakers on two sides and on the top of the enclosure in a "Tri-Polar" configuration. Two left and right 1.25" mid/high-frequency speakers, at a 90° angle to each other on opposite sides of the cabinet, create a much wider soundstage with a greater sense of stereo separation. The top mounted drivers include a 5.25" midbass woofer and a 1.25" mid/high-frequency driver that fire upward. These speakers add powerful bass and a sense of image height.

Bluetooth Audio Streaming w/ AptX: The Definitive Technology Cube supports Bluetooth A2DP/AVRCP which allows you to wirelessly stream audio from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Blackberry, laptop/computer, etc.. You'll be able to stream stored music or music apps from your Bluetooth-enabled device.  The Cube employs AptX audio coding technology for lossless, audiophile-quality streaming with compatible AptX-compatible phones. You can even control basic playback functions (such as Play/Pause) from the Cube speaker.Advanced music navigation and song/artist information will still be handled by your Bluetooth-enabled device.

Simple Pairing: The Cube pairs wirelessly and effortlessly with Bluetooth enabled devices with a single press of a button. Bluetooth-enabled devices (like Android) that have Near Field Communication (NFC) are even easier to pair with; simply touch the device to the Cube and they're paired. Once paired, the Cube will automatically re-connect to your device when within range (up to 33').

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Definitive Technology Cube.

Auxiliary Input: The Cube Bluetooth speaker is also fitted with a 3.5mm auxiliary input to connect virtually any non-Bluetooth portable audio device with a headphone output.

USB Charging Port: The Definitive Technology Cube features a USB (type-A) port used to charge your smartphone or other USB-enabled portable audio device. You can choose to power your device using either AC or battery power. However, charging with battery power will reduce battery life. If batteries are already weak, the USB connection will not charge your device. This USB port does not support audio playback.

Rechargeable Battery + AC Power: AC household current powers the Cube, but it also has a built-in rechargeable Lithium-Ion battery. While plugged in to AC power, the Cube charges the internal Li-ion power pack (takes approximately 3 hours to acquire a full charge). When you want to take the wireless speaker to another room of your house, simply unplug the power cord and carry it anywhere you want full-fidelity sound for up to 8 hours of battery-powered listening (at moderate listening levels).

Carry Handle: A handy notch on the back of the Cube makes it easy to pick up and move.

Very Impressive

Written By MarkW, Santa Barbara, CA on Monday, July 28, 2014
 
Impressive speaker. Definitive has done it again. Easy pairing with any Bluetooth device. The kicker was the stereo mini-jack input which allows for use of my high def music player with the speaker. It can get loud with no noticeable distortion. Excellent bass - adjustments may be necessary from the input device if it seems too bottom heavy.
Pros:
Sound quality, portability, ease of use.
Cons:
None noted so far.

Crutchfield Customer Review (What's this?)
 
After deciding to purchase a bluetooth speaker I made the trip to the local bestbuy to audition speakers available. Having read many of the reviews online, I was leaning towards the klipsch model. But after hearing this unit I was not impressed by its sound quality compared to a dr. dre model of the same price. Also both these speakers do not have built in battery charging capability. Being familiar with Definitive Tech products I went out on a limb and bought the D-cube sight unheard. THIS THING ROCKS! It has a lithium ion battery onboard with its own charger, apt-x technology and plays about 7 hours on one charge. All this as the same price as the other models that don't have the charging capability. Also this unit has NFC capability making connection very easy. A great choice for any situation that requires good crisp, clear, loud music with superior base.
Pros:
great sound small package
Cons:
high price but you get what you pay for

Small Package, Big Sound

Written By MANIKENZ, NYC on Tuesday, April 22, 2014
Crutchfield Customer Review (What's this?)
 
I'm incredibly impressed with both Def Tech as a company and now the Cube. After going into a local store and listening to the Cube I was immediately struck by the clarity and quality of sound the little box was able to produce. It was much cleaner than the competing small audio boxes around it.

I could not have predicted how much better it would sound at home. In the store I felt it lacked some low end, but that the clarity and separation made up for it. Once set up in the house I shocked at quality of the subs. From the other room there is no way one would guess that the Cube is the size of a toaster. I really can't say enough about the size to audio ratio, it's simply stunning.

Lastly, the portability is also an incredible feature. To be able to unplug the box and carry it into other rooms (and particularly onto my roof) and not worry about the battery dying any time soon is killer. Also the fact that there are no disposable batteries to deal with is awesome.

In summary, if you're in the market for a small, portable, and high quality speaker system, I have no reservations in recommending the Cube.
Pros:
Size Sound Quality Portability Rechargeable battery Easy Set Up
Cons:
High price point, but you get what you pay for in this case.
