| DESIGN Prepare for the next step in auditory revolution with the musical and tonal genius of Phil Jones. Phil Jones’ achievements in audio engineering made him the ideal lead designer for AirPulse. Since 1994 Phil has been designing and producing AirPulse loud speaker systems that have won awards such as the Golden Sound Award for the best loud speaker developed in the last 100 years. Phil’s speakers have been used by legendary studios such as Abby Road Studios. Now, Phil aspires to bring about the next generation of sound with AirPulse. |  |
| Cabinet Construction The A300 cabinet is built from 25mm rigid MDF with cherry wood veneer finished in satin lacquer. Strong internal bracing supports and stabilizes the drivers and eliminates cabinet resonance to minimum. To further reduce coloration, cabinet interior is fully lined with 36mm thick waved sound absorption material. |  |
 | Horn Loaded Ribbon Tweeter The A300 horn loaded ribbon tweeter inherits the mechanism of the tweeter in our flagship 7001 near field monitor. The thin aluminum ribbon diaphram has high sensitivity, superb transient response, extended frequency range and well defined resolution. |
| 6.5” Aluminum Cone Low Distortion Mid-Woofer The Mid-woofer is a powerful 6.5 inch unit with a hard anodized aluminum alloy cone suspended in a heavy duty, 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. It features a huge Underhung motor structure with a high gauss Neodymium magner and a 50mm diameter edge-wound copper clad aluminum ribbon voice coil to gain maximum linear excursion and control. This structure also reduces the weight of the driver allowing the speaker to have a very fast transient response as well as total loss-modulation distorttion. |  |
 | 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 boasts to have 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. |
| Full Digital Amplifier The power amplification part is built with 3 pieces of TAS5754 Class-D amplifier from Texas Instrument. This component is one of a handful of Class-D amplifiers in the market which combines high input sample rate support and high output PWM carrier frequency. These two characters are essential to achieve low background noise and low distortion. 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 fre-quency, twice to 384KHz of traditional Class-D amplifier, is even more suit-able to drive the high sensitivity ribbon tweeter. Each of the left and right channel mid-low range speaker Is driven dedicatedly by one TAS5754 connected in parallel bridge mode. The third TAS5754 is connected in bridge mode for left and right channel ribbon tweeters. |  |
