The Airpulse A300PRO Bluetooth Speaker System is finished with a conservatively elegant walnut wood veneer. Sonically, it has the same horn-loaded aluminum ribbon tweeter as the A300, but with an improved 6.5" aluminum cone, low distortion woofer. The power supply and amplifiers in the left and right speaker of the A300PRO is completely symmetrical. Each speaker has an internal 150W high-efficiency, low-ripple switching power supply.

Using a Texas Instruments TPA3251 digital power amplifier, each cabinet has a woofer output power of no less than 120W and a tweeter output at 10W. The speakers also use the XMOS xCore200 multi-core processor and Texas Instruments TLV320AIC3268 digital processor. The interconnection of the left and right speaker uses KleerNet wireless transmission technology. It uses Qualcomm QCC3031 series 5.0 Bluetooth chipset and supports the aptX HD high-fidelity codec, so that Bluetooth technology can be used with minimal signal loss. The A300PRO cabinet is constructed with 1" high-strength MDF, and to ensure optimal signal transmission, Airpulse uses TRANSPARENT internal speaker cables.

The construction of its 1" thick high strength fiberboard cabinets with strategically placed internal bracing lay down the foundation for sound quality. The interior is also lined with a 1.4" thick professional wave-absorbing material to enhance the absorption of excess standing waves.

A300PRO's 6.5" woofer uses a high-strength magnesium-aluminum diaphragm and an underhung magnetic circuit design. It is supported by a 2" diameter voice coil and an oversized, high-energy magnet. Combined with a cleverly designed heat dissipation mechanism, this woofer has a low distortion and high level of dynamics, delivering clean low frequencies that are richly detailed and deeply extended.

Airpulse's unique horn-loaded aluminum ribbon tweeter in the A300PRO delivers sound to every corner of a wide space with airy and harmonically pleasing high frequency musical notes. This even distribution mode is not affected by the reflection characteristics of the room, so that the high-frequency notes are more articulate and three-dimensional.

Besides the audio front end components, the core signal processing is built on an XMOS xCore200 multi-core processor and a Texas Instruments TLV320AIC3268 DSP chip. Class D amplifiers used inside the speakers are Texas Instruments TPA3251.

Wireless signal distribution between left and right speakers is built on the microchip's proprietary technology known as KleerNet. The radio is transmitted over the 5.2 and 5.8 GHz spectrums, and with a 22 MHz radio bandwidth, the technology works to deliver lossless audio signal transmission. Besides the pair-used left-and-right wireless stereo scenarios, the system offers an independent left and right configuration, just as traditional monitor speakers, which are often seen to be used with mixing consoles in recording studios. A300PRO features both a symmetrical acoustic and electrical design, and both left and right speakers are active.

The Bluetooth audio receiver is built using the QCC3031 from Qualcomm, which is a Bluetooth 5.0 chipset with the aptX HD high-fidelity codec. It can offer a much better audio playback experience than the traditional Bluetooth SBC audio. A300PRO also offers a USB digital audio interface which supports UAC2 digital audio application. An ASIO audio drive is provided to enable Windows users to have a high-quality low latency signal path out.

Airpulse selected Transparent brand internal connections to ensure maximum accuracy of signal transmission.

The A300PRO comes with a wireless remote control used for taking control of your sound. You can switch between inputs easily from the comfort of your seat.
