Firstly, the basket, or frame, is of aluminum die casting. It has four characteristics which are stable quality, beautiful in appearance, accurate in its performance and strong enough to withstand heavy-duty use. Secondly, its relatively light weight reduces the total weight of a speaker and in transportation and installation make things just that little bit simpler. Thirdly, The high-strength aluminum alloy ensures the basket is extremely robust, capable of standing up to frequent use without affecting its performance in any way. Fourthly, Its excellent heat dissipation properties ensure that the internal components in our speaker never overheat, thus guaranteeing a long life for our product. Finally, the precision engineering of the die casting process means the resulting products are a delight to the eye, which must surely help complete any audio system! All of the above advantages constitute a better product, one that is more reliable and will last you longer.
