Enclosure Design
As BOB's iconic product, AS series has integrated all BOB's high technique of enclosure's manufacturing. In order to achieve the perfection we do our best to
improve the standards of sheet metal and surface treatment. The enclosure of AS200 series is made of high quality Finland multi-layer birch plywood, this
kind of birch plywood is specially made to meet acoustical design that leading the enclosure solid and good acoustical character. For consistency and preventing form copy, BOB use its special
enclosure installation technology such as mortise structure, cold bonding and high pressure positioning etc. to bond the cabinet firmly. The surface is protected by the extremely durable
elastic waterproof material coating, highly antiscratching and hitting, can be applicable to any harsh environment.
As BOB's flagship model, AS362 uses cold pressing carbon fiber processing technology, the enclosure which make of carbon fiber is totally different form the wooden one because the strength of carbon fiber is 10 times comparing with wood but 60% lighter than plywood at the same size. So our enclosure is lighter but stronger than the traditional one. After years of constantly explore new technology, we significant improve our production technology to lower the costs to reach customers' acceptable line. The advanced cold pressing processing technology processed each part becoming a shape, then combining them with special bonding technique and coating the surface with elastic waterproof material, highly anti-scratching and hitting.

AS 300 Series

Be considered of sound-wave's projection in level, the big size system AS series is design in symmetrical structure. HF driving units lay in the central of enclosure vertically, MF units are in both sides of the HF ones, and the LF units are placed in both ends horizontally. This arrangement leads normal polarity symmetric that giving the system the whole working
frequency range. Symmetrical structure design has the same configuration as coaxial driver; it makes the loudspeaker of AS300 series having a uniform sound field coverage in every angle of its effective range.
