1 item left

The A80 is AIRPULSE introduction to plug & play HiFi. Designed to appeal to a younger audience through its ease of use, multiple connections and functionality, this beautiful walnut finish speaker boasts high end & hifi components at affordable pricing. The A80 active speaker is the ideal entry into HiFi listening.

Following the successful launch of the A200 and A300, the all-new A80 diminutive bookshelf speakers with a 4’5” aluminum cone ferrite magnet woofer now join the Airpulse active speaker family. The perfect combination of Hi-Res digital audio processing technology and a youthful sturdy system that pays homage to hifi speakers of old, the A80 is a High-Fidelity audio system with intoxicating sound quality and immense visual appeal. The A80 adopts its sound characteristics from our flagship model the 7001 near-field monitor speakers designed by Phil Jones. Using the same XMOS core as its older siblings, this unassumingly basic cabinet delivers outstanding performance beyond expectations.

SOUND 

HORN LOADED RIBBON TWEETER

 

The A80 Horn loaded ribbon tweeter it same as A100’s, the thin aluminum ribbon diaphragm has high sensitivity, superb transient response, extended frequency range and well-defined resolution.

The meticulously formulated horn shape produces directional and optimized high frequencies from the ribbon tweeter, so they are aimed at the listeners, minimizing unwanted effect from room reflection.

 

 
 

4.5INCH ALUMINUM CONE 30MM VC 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 mid-woofer was designed from painstaking analysis of all types of cone geometry and materials using a Klippel Laser Doppler Interferometer.

The 30mm diameter voice coil is unusually larger than most loudspeakers of this size. It has been shown that larger voice coils have less power compression because they run at a cooler operating temperature.

ULTRA-LOW DISTORTION SIGNAL PROCESSING AND AMPLIFICATION SYSTEM

The entire digital system is built on a multi-core signal processor XMOS XU216, a 16-core powerful audio processor based on XMOS xCore200 architect, which is proud of having up to 2000MIPS processing horse-power.

 
 

FULL DIGITAL AMPLIFIER

The power amplification part is built with 2 pieces of TAS5754 Class-D amplifier from Texas Instrument. The up-to 192 KHz input sample rate support guarantees the entire link of digital processing run without any change of sample rate of signal. Its 768 KHz output PWM carrier frequency, twice to 384 KHz of traditional Class-D amplifier, is even more suitable to drive the high sensitivity ribbon tweeter.



The analog front end uses top-of-the-line components from Texas Instrument. With special configuration, the chipset work at 96 KHz to offer a frequency response up to 40 KHz.

The SPDIF receiver PCM9211 is also from Texas Instrument, which supports input sample rate up to 216 KHz. With very low output jitter, the unpacked audio signal can be delivered to XMOS processor with zero loss.
