The Audience A3 is a breakthrough full range loudspeaker driver design comprised of the patented XBL motor, patent-pending suspension and patent pending basket. The A3 has an exceptionally flat response from 40Hz to 22Khz and -20 at 20Hz with very high power handling and dynamic range. The A3 is built like a high power sub woofer driver using a large neodymium motor structure, big voice coil and suspension venting. The A3 is ultra responsive at 2.5 grams total moving mass providing state of the art resolution and dynamic range. The A3 sports 12mm of usable excursion with less than 1 dB compression at levels up to 95 dB SPL.
The XBL A3 motor design generates an extremely uniform force over the excursion range, resulting in much less distortion and compression . The A3 motor design also allows for an extremely low voice coil inductance, insuring exceptional flat response to higher frequencies.
The A3 surround, patent-pending, is uniquely s shaped allowing for the surround to provide large excursions without shrouding the cone and with uniform resistance in both directions.
The A3 basket, patent-pending, supports the structure while free of typical design resonances, it is unobstructive and avoids trapped air volumes. The mechanical design was extensively refined using state of the art Finite Element Analysis to have no mechanical resonance problems.
The A3 spider was designed with special materials and design that provide for large linear excursions and is of a size usually associated only with much larger drivers.
The A3 pole piece venting is also unusual in that a vent of this size is usually only seen in much larger sub woofer type drivers. This large vent has radiuses on both ends to prevent turbulence. This large vent supports high volume air flow for cooling the voice coil for superior power handling.
The Cone is a curvilinear design executed with an anodized aluminum magnesium alloy making for an exceptionally rigid cone. The concave dust cap is made of a proprietary material providing constrained layer damping to control cone break up at high frequency and to provide high frequency desperation.
The above are some, not all, of the unique and special design features of the A3. Under development is an A3 driver version that will have dual 8 ohm voice coils providing for 4, 8, or 16 ohm connections.
这些3" 4" 8"的全频,都比不上楼上的12"全频,灵敏度低了近10dB!

3“.4”.8“.12”用场不同，不能一样看待
希望钟灵多发些相关图片和测试

人家阿龙那个12“全频喇叭是上帝指点的，两个同尺寸规格的喇叭，竟然能做出不同的Sd来！
