This pair of Airpulse A80 Bluetooth Speaker System uses a horn-loaded aluminum ribbon tweeter and a 4.5" aluminum cone mid-woofer driver. They are housed in a 0.7" thick high-strength MDF cabinet with a beautiful walnut finish. Transparent brand cable is used in the A80 for internal connections to ensure minimum signal loss. The active speaker has a high efficiency Class D amplifier with a digital signal processing (XMOS) system, powered by an efficient power supply. The A80 supports multiple inputs, including Bluetooth, AUX, PC, USB, and optical. Frequency response ranges from 52 Hz to 40 kHz and they support certified Hi-Res audio playback.
Cabinet Construction
The A80 cabinet is built with 0.7" thick high-strength MDF with a beautiful walnut finish.
Horn-Loaded Ribbon Tweeter
The A80 horn-loaded ribbon tweeter is a thin aluminum ribbon diaphragm with high sensitivity, superb transient response, extended frequency range, and well-defined resolution. The meticulously formulated horn shape produces directional and optimized high frequencies, so they are aimed at the listeners, minimizing unwanted effects from room reflection.
4.5" Aluminum Cone / 1.2" Voice Coil Mid-Woofer
The mid-woofer is a 4.5" unit with a hard anodized aluminum alloy cone suspended in a heavy, ultra-rigid cast magnesium alloy frame. The proprietary aluminum alloy cone (PAAC) of the mid-woofer is designed from analysis of all types of cone geometry and materials using a Klippel laser doppler interferometer. The 1.2" diameter voice coil is made to have less power compression and runs at a cool operating temperature.
Ultra-Low Distortion Signal Processing & Amplification System
The entire digital system is built on a multi-core XMOS XU216 signal processor, a 16-core powerful audio processor based on the XMOS xCore200 architecture, which has up to 2000 MIPS of processing horsepower.
Full Digital Amplifier
The power amplification features two TAS5754 Class-D amplifiers from Texas Instrument. The up to 192 kHz input sample rate support ensures that the entire link of digital processing runs without any change of signal sample rate. Its 768 kHz output PWM carrier frequency, twice that of the 384 kHz of traditional Class-D amplifiers, drives the high sensitivity ribbon tweeter.
Texas Instruments
The analog front end uses a specially configured Texas Instruments chipset working at 96 kHz with a frequency response up to 40 kHz. The PCM9211 S/PDIF receiver from Texas Instruments supports an input sample rate up to 216 kHz. With a very low output jitter, the unpacked audio signal can be delivered to XMOS processor with zero loss.
Bluetooth 5.0 with aptX
The Bluetooth audio receiver is built on Qualcomm's Bluetooth 5.0 chipset, which supports aptX decodeing, and better audio playback than a traditional Bluetooth SBC codec.
Back Panel Control
Volume of the subwoofer can be adjusted by the master volume control. A80's independent treble and bass adjustment function can help the user to easily set the brightness of high frequencies and the amount of bass according to size of the listening environment. The USB digital audio interface on the A80 supports UAC2, which can hold an input sample rate up to 192 kHz. This audio application effectively avoids signal degradation and dynamic range loss due to the PC audio DA.
Transparent Internal Wiring
The A80 uses Transparent brand audiophile grade speaker cable for their internal wiring, working to transfer signals with accuracy and minimal loss.
