Sell AirPulse A80 Active Hi-Res Audio Certify Bluetooth Wireless Bookshelf Speaker (Designed by Phil Jones) best price

Product overview The A80 continues to use AIRPULSE's unique horn-loaded aluminum ribbon tweeter and a proprietarily-designed 4.5 inch aluminum cone mid-woofer driver. They are housed in an 18-mm thick high-strength MDF cabinet with beautiful walnut finish. The well-known American TRANSPARENT cable is used in A80 for internal connection to ensure minimum signal loss. The active speaker has a high efficiency Class D amplifier with digital signal processing (XMOS) system, powered by an also efficient power supply. The system in the A80 supports multiple inputs, including Bluetooth, AUX, PC, USB and fiber optic. Frequency response ranges from 52Hz to 40KHz. It supports Hi-Res high-quality audio playback, and has obtained a Hi-Res official certification. Horn Loaded Ribbon Tweeter The A80 horn loaded ribbon tweeter is the same as A100’s, its 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. This also leads to a superior imaging of the speaker. The result is full and three dimensional sound with each detail well defined. 4.5 inch Aluminum cone 30mm Voice Coil Mid-woofer The Mid-woofer is a 4.5 inch 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 was designed from painstaking analysis of many 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. Sonically this means a more realistic dynamic representation of the music. It is dynamics in music that gives 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. For uncompromised performance, the A80 woofer uses a hyper-rigid cast-magnesium alloy frame. Its rigidity greatly reduces speaker coloration; and its material helps to dissipate heat efficiently from the voice coil much faster than a typical steel speaker frame, which all in combination leads to increased dynamics and power handling and ultimately, a satisfying musical experience rarely gained from a system of this size price range. Cabinet Construction The A80 cabinet is built with 18-mm thick high-strength MDF with beautiful walnut finish lto further reduce coloration. The cabinet interior is fully lined with professional waved sound absorption material. The oval shaped vent tube in the A80 is carefully designed to minimize wind noise. TRANSPARENT Internal Wiring The A80 uses TRANSPARENT audiophile grade speaker cable made in the USA for internal wiring. Signals are transferred with utmost accuracy with minimum loss,which brought you much closer to music! 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. With its unique parallel structure, it is perfectly made for timing-sensitive signal process like audio, especially audio with high sample rate. The dual clock structure at the output stage effectively avoids signal modification between different sample rates, and can further reduce signal distortion.
