1400 Watt 12 Inch Car Subwoofer - Single 4 Ohm Voice Coil, Box Ready Break Your Subwoofer In. 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. Polypropylene is a resilient and durable manufactured material. It allows for maximum flexibility that produces great sounding speakers. The longer coil windings of a copper voice coil cover more turns of wire in the magnet gap at high excursion. The denser anatomy of copper translates in having to expend less power to reach higher efficiency. Stamped baskets have better Resonant Frequencies. This means that the frame is able to absorb and transfer much of the energy produced by the speaker. It is more durable and harder to damage or break, good corrosion resistance, high thermal/electrical conductivity and retains strength at high temperatures Foam is a great material for surrounds in speakers and subwoofers. It is in general more flexible than rubber, providing a slightly higher efficiency. This also translates to better excursion. (How far the cone of a speaker linearly travels from its resting position). It generally lasts anywhere from 8 to 15 years under the right conditions of usage
