The Best Sounding Bluetooth Speaker

Overview

Rhombus uses state of art digital technology to get maximum audio quality from various inputs such as bluetooth, USB digital streaming and optical input.

Enhanced Bluetooth Sound

Rhombus enhances sound quality by adopting proprietary asynchronous sample rate converter technology to upgrades the bit resolution and the sample rate to 24bit, 192KHz to reconstruct original sound quality as much as possible.

Digital USB streaming and full-digital amplification

Rhombus has 24bit lossless USB digital streaming audio input for iDvices and new generation Samsung phones. Optical input for CD?DVD is also included. The input is processed fully in digital domain, and amplified by a full-digital amplifier. This combination of a digital connection and digital amplification allows Rhombus to produce crystal-clear sound.

24bit High Definition Signal Processing

The processor handles inputs from Bluetooth, USB, and SPD/IF, crossover between the main drivers and subwoofer, frequency response correction, and sound stage enhancement with 24-bit high definition.

Top-of-the-line Danish-designed drivers

Peter Larsen, a legendary Danish speaker engineer who was chief engineer of Vifa, Scan-Speak and Dynaudio designed both the custom 2 inch full-range unit and the compact subwoofer for Rhombus.

Enhanced Bluetooth Audio Quality and Up-Sampling Process

Enhanced Bluetooth Audio Quality and Up-Sampling Process

Bluetooth has become a ubiquitous standard in many devices. Because of the inherent nature of its lossy encoding algorithms, it has limitations in delivering true hi-fi quality sound. However, Rhombus enhances sound quality by adopting proprietary asynchronous sample rate converter technology to allow better sound reproduction. The up-sampling technology was only used by high-end audio products that cost thousands bucks or more until recently. The sample rate converter cleans up timing of audio clock degraded by unstable wireless transmission. At the same time, it upgrades the bit resolution and the sample rate to 24bit, 192KHz to reconstruct original sound quality as much as possible.

Whereas Bluetooth is a very convenient for casual listening, Palo Alto Audio didn’t ignored need of serious audiophiles. Most of analog input or Bluetooth speakers suffer from various noises in the analog signal path. Rhombus added 24bit lossless USB digital streaming audio input for iDvices and new generation Samsung phones. It also has SPD/IF for high-fidelity audio playback from CD/DVD or TV.
Advanced digital signal processing and True Digital Amplification

Advanced digital signal processing and True Digital Amplification

The amazing sound quality is achieved with a help of the very best state-of-the-art digital signal processing (DSP) technology. We use the very best state-of-the-art DSP/PWM processor with state of the art digital signal processing (DSP) technology. The processor handles inputs from Bluetooth, USB, and SPD/IF, crossover between the main drivers and subwoofer, frequency response correction, and sound stage enhancement with 24-bit high definition. Finally the digital signal is fed to digital class-D amplifier, so that it stays purely in the digital domain all the way to the speaker units. You can hear both crystal clear high and mid-range and rich and natural bass much better than similarly sized speakers.
Beautiful Modern Design

Beautiful Modern Design

Rhombus is true proof that fabulous design and state-of-the-art acoustic engineering can be combined in a pleasing harmony. Rhombus will fit into every living room, kitchen, bedroom and all spaces in between. Stylish and elegant, it blends into any living environment. Industrial design of Rhombus was done by of Innodesign based in Palo Alto. The founder, Young-se Kim, who is well known international design celebrity, has taken care of all the details of aesthetics of Rhombus.

Custom Driver Unit Designed by Legendary Peter Larsen

Palo Alto Audio Design has developed dedicated speaker units optimized for the system. Peter Larsen , a Danish audio specialist, a legendary speaker engineer who was chief engineer of Vifa, Scan-Speak and Dynaudio for many years. He is well known by his invention of ring radiator tweeter produced by Vifa. He designed both the 2 inch full-range unit and the compact subwoofer for Rhombus. The 2 inch full range unit produces incredibly accurate sound at mid and high frequencies. The down-firing 3.5 inch subwoofer reproduces surprisingly significant bass irrespective of relatively small size.

Universal Compatibility

These speakers work with nearly every Smartphone and Tablet on the market. Easy Bluetooth pairing allows Rhombus to be compatible with most iDevices, smartphones, PC and many other Bluetooth audio products. If you prefer to listen to the best possible sound quality by digital USB streaming, you can connect the USB charging cable from your device to Rhombus.
