Eminence's LAB 12 subwoofer driver is recommended for vented, sealed, and horn-loaded professional audio enclosures. The driver features long-throw construction with a heavy-duty 12-spoke die-cast aluminum frame and KevlarÂ® reinforced paper cone. In a horn-loaded configuration, a pair of these 12" drivers can produce low-distortion bass output comparable to 6 or 8 conventional 18" woofers. Also great as an automotive sub.
