Buying Guide for Memphis 12-inch Subwoofers for Cars
A decision about what subwoofer is right for you comes down to the details. Memphis 12-inch car subwoofers provide that bass thump you may want for your car audio system.Why do many subwoofers contain paper cones?
Using paper for subwoofer cones has a practical purpose. The cone needs to be quite stiff while also being lightweight to the point of nearly no weight at all. However, few materials meet those requirements. Paper, with a variety of additives, comes the closest and produces a round, deep sound that drives that elusive low beat. Plastic cones can be effective at higher audio ranges or even for mid-tone bass. Many people feel plastic cones cannot snap with that clear, low-toned boom required.
You will seldom find a woofer using an untreated or uncoated plain paper cone. Materials added as paper enhancers include wool, carbon fiber, fiberglass, or polypropylene. Plain paper absorbs moisture from the air that affects the damping and changes the mass. The aforementioned materials add ingredients to paper to inhibit moisture for good sound quality. A stiff, lightweight paper cone with the right additive produces a clear, pounding thump that every bass lover seeks.What is a wet-wound voice coil?
Considered scientifically superior, Memphis uses wet-wound voice coil wire for its car audio wire. When using a wet-wound process, the wire for the voice coil is dipped or drawn through an adhesive bath before it is wound on the bobbin, also called a former. This process allows good adherence overall for the voice coil wire. Drawing or dipping the coil wire is a technique that requires operator skill to utilize it. An adhesive-coated bobbin paired with a wet-wound wire bond provides the strongest subwoofer structure. It remains utilized more in Europe and other areas of the world than in the United States.
Alternatively, a dry-wound process may take different forms. One dry-wound method uses solvent to active wire pretreated with thermoplastic adhesive, and it is then baked it in an oven. This produces coil wire that is efficient for many purposes. Another dry-wound technique simply winds the dry coil wire around the bobbin before applying an adhesive to the top layer to keep it in place. When this voice coil wire meets conditions causing it to heat up, the adhesion does not hold the wire in place. Instead, the wire softens and comes loose from the bobbin.What power handling ranges do these subwoofers contain?
- Watt range: 200 RMS to 1000 RMS
- Peak values: 400 RMS to 2000 RMS
- Impedance: 2 ohms to 8 ohms (depending on a single voice coil or duals with 4 ohms apiece)
However, keep in mind that a sealed or ported enclosure with the right specifications makes a regular-sized woofer outperform one twice its size that does not have a dimensional box. Power handling capacity paired with the proper enclosure and amp system provides a broad overview for performance purposes.Content provided for informational purposes only. eBay is not affiliated with or endorsed by Memphis.
