For the car audio enthusiast looking for serious SQ (sound quality), check out the Illusion Audio E10 Electra Series subwoofer. This is a single 10-inch sub designed for accurate, powerful bass. It features an aluminum-coated polypropylene cone with a rubber surround, mounted on a powder-coated steel basket. It has a beefy 50mm voice coil and is rated for 300 watts RMS (600 watts max). The specs are impressive for a sound-quality sub: an Fs of 28.84 Hz, an Xmax (linear excursion) of 14mm, and it works great in a relatively small sealed enclosure (recommended 0.75 cubic feet). The overall diameter is about 10.1 inches (257mm) with a mounting depth of 5.55 inches (141mm). If you're building a system where clean, tight, and musical bass is more important than just sheer loudness, this sub from a respected high-end manufacturer is a fantastic choice. It's built with quality materials and engineering for those who appreciate fine audio.
