Planet Audio BBD12B Big Bang Series 12 Inch Car Audio Subwoofer
Much like the engine of a new automobile, a new subwoofer must go through a short but important process of "break-in" before it is run under harsh conditions. The "break-in" process will ensure the subwoofer is able to perform as it has been designed to. This process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure. 3-4 hours is generally sufficient for the subwoofer's suspension to loosen enough to prevent the voice coil(s) from overheating and causing failure. The break-in period is also effective in extending subwoofer life. Over-driving the woofer before it has been properly broken-in will usually result in premature failure and poor performance.

Series Name: Big Bang, Model: BBD12B, Size: 12-inch. Impedance: 4 Ohms, Mounting Depth: 7.82 inches. Mounting Hole Diameter: 11.12 inches. Dimensions: 13" x 13" x 8.5, Weight: 21.76 lbs. Resonant Frequency: 28 Hz, Sensitivity (1 Watt/1 Meter): 83 dB.

Cone: Pressed Paper, Surround: Foam. Basket: Cast Aluminum, Box Type: Sealed & ported. Pressed paper is more rigid and able to handle the high power and functionality. You don't want the cone of a subwoofer to have a flexible structure to it. The stiffer the cone is, the better sound quality you will receive. Foam is an alternative for the surround in speakers and subwoofers. In general, more flexible than rubber, giving the woofer a slightly higher efficiency. This also translates to better excursion. (How far the cone of a speaker linearly travels from its resting position).

A Dual Voice Coil subwoofer will not produce more bass than a single voice coil subwoofer. It is more about producing the right ohm load for maximum efficiency from the amplifier that you are running.

The less resistance, the more power that the amp will put out. Cast Aluminum has better resonant frequencies and vibrates less. This translates to a frame that is able to absorb and transfer much of the energy produced by the speaker. It is durable and harder to damage or break, has good corrosion resistance, high thermal and electrical conductivity and retains strength at high temperatures.
