Airpulse A100HD Active Speakers

Airpulse A100HD Active Speakers

Enter the world of superior audio performance with the Airpulse A100HD Active Speaker System, the entry level model for audiophiles in the early stages of their musical appreciation journey. Hi Res certified, the A100HD speaker is the perfect companion to play high resolution audio files in PCM or DSD formats.

Following the successful launch of the A200 and A300, the all A100HD bookshelf speakers with a 5” (127mm) woofer now joins the Airpulse active speaker family. The perfect combination of Hi-Res digital audio processing technology and an aesthetic of understated elegance creates a High-Fidelity audio system with intoxicating sound quality and visual appeal. The A100HD has an exquisite appearance, inheriting the appearance and sound characters of Airpulse’s flagship model 7001 near-field monitor speakers designed by Phil Jones. Using the same XMOS core as its bigger brother A300, this unassumingly small cabinet delivers outstanding performance beyond your expectation.

Horn Loaded Ribbon Tweeter: The A100HD horn loaded ribbon tweeter inherits the mechanism of the tweeter in the flagship 7001 near-field monitor speaker. The thin aluminium 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. This also leads to superior imaging which results in full and three dimensional sound with each detail well defined.

5” Aluminium Cone Low Distortion Mid/Woofer: The mid-woofer is a 5” (127mm) unit with a hard anodized aluminium alloy cone suspended in a heavy, ultra rigid cast magnesium alloy frame. The proprietary aluminium alloy cone was designed through a meticulous process analysing different types of cone geometry and materials using a Klippel Laser Doppler Interferometer. The 35mm diameter voice coil is 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. Sonically this means a more realistic dynamic representation of the music as it’s dynamics in music that give it emotion and exhilaration. The cooler running temperature of the voice coil also has the side benefit of a more reliable loudspeaker since cooler voice coil means much less chance of speaker failure.

Fully Digital Amplifier: The power amplifier is built around two TAS5754 Class-D amplifiers from Texas Instruments. This component is one of a handful of Class-D amplifiers on the market which combines high input sample rate support and high output PWM carrier frequency. These two characteristics are essential to achieve low background noise and low distortion. The up-to 192 KHz input sample rate support guarantees the entire link for digital processing runs without any change in sample rate signal. Its 768 KHz output PWM carrier frequency, double the typical 384 KHz found in traditional Class-D amplifiers, is more suited to driving the highly sensitive ribbon tweeter. One TAS5754 is connected in bridge mode to the left and right channel woofer while the other amp is connected in bridge mode to the left and right channel ribbon tweeters.

Enhanced Baffle Design: The front baffle of the A100HD is constructed with 25mm-thick MDF, surpassing the 18mm thickness of the standard A100. This enhancement provides greater depth in resonance, making it ideal for delivering high and mid-range frequencies with full intensity.
