UCube speakers run off USB, are coming to an Amtrak quiet car near you

You can use these USB-powered UltraLink UCube speakers on a bus, on the beach, or on the table at your favorite McDonald's, but please -- for the love of god -- don't. Remember: with great convenience comes great responsibility, and if these speakers are as impressive as the dramatic marketing video below implies, disruption of the peace is about to know no bounds. At $150 per pair, these sleek sound machines aren't cheap, but each speaker is able to pump out 15 watts of peak power -- you won't be filling a large room with crisp, distortion-free sound, but they're probably loud enough to play your tunes or flicks for a group of friends, or to annoy strangers in a park. UltraLink claims that the speakers use DSP-controlled power supplies to "store energy during quiet passages," allowing the 3.25 inch cubes to reach their 15 watt peak output with 170-degree listening angles. We haven't had a chance to go hands on, but if these speakers sound half as good as they look, we may have a better solution for playing music in the CES trailer next year.

UltraLink Debuts First Product in New Personal Audio Brand

UFi... It's All About U!

Ontario, California • 5/17/2011 • A new UltraLink® personal audio brand called UFi™ launches the first in a new line of products, the $149.99/pr UCube Compact USB Digital Speakers.

Wherever you hang, your music and movies follow! At just three-inches square UCubes are personal and portable, ideal for home, on your desk or on the go! Available in brilliant fashion-forward colors they look as fabulous as they sound on custom brushed aluminum stands. It's one look and "I want them!"

You're gonna love their small sleek footprint, iconic design and big dynamic sound; they create a wide stereo image so everyone can enjoy music and video! Just plug the speaker with the USB connector into your computer's USB port and you're ready to roll! UCubes... for U!

Inside UCubes

We designed UCubes with equal parts science and art. DSP-controlled power supplies and DSP-equalized signals for the very special BMR Balanced Mode Radiator driver deliver an astounding 170 degrees of stereo image so everyone can enjoy the experience. UCubes are artful too; their gorgeous custom aluminum stands put them at just the right angle for listening, and their smooth, shiny surfaces and beautifully curved sides look iconic, elegant and awesome!


All-USB signal and power delivers vastly improved sound and supreme portability with a minimum of cabling and no external power supply. Connect the speakers with the cable provided, then plug the left speaker into your computer's USB port and you're ready for music, movies or video wherever you are. UCubes will in most cases self-install, but if not check the UCube Tech Zone!

Digital Signal Processing

While USB ports are limited to 5 volts, UCubes' "smart" DSP-controlled power supplies store energy during quiet passages allowing the class-D amplifier to reach a full 15W equivalent power output for clean, dynamic sound that won't break up when you pump up the volume. The audio signal is also DSP-equalized to perfectly match the UCube's special BMR driver and enclosure eliminating the need for a crossover.

BMR Driver

The advanced-design BMR Balanced Mode Radiator is a full-range, flat-diaphragm driver that delivers vastly improved off-axis response of up to 170 degrees, true room filling sound. Casually place UCubes wherever convenient, or place them both sides and equidistant from your computer facing straight ahead, then slowly turn them in towards you. Find just the right balance between their awesome focus and the positively huge listening area. You'll be surprised to hear that the sound doesn't come from the speakers but from the space around them!
