Dayton Audio once again proves its reputation for quality and performance.

• 4 Ohm and 8 Ohm impedance are perfect for series pairs in MTMs and center speakers
• Outstanding car audio mid-range
• High-quality, low-distortion motor with two short-circuit paths to reduce inductance

The Dayton Audio Reference Series sets new standards in high performance speaker drivers. Utilizing a low distortion motor system with dual shorting paths and a rigid aluminum cone, the Reference Series outperforms drivers costing many times its price. The low distortion characteristics and high excursion provide exceptional clarity, detail and dynamics. The woofer has a black anodized cone, heavy-duty 6-hole cast frame, low-loss rubber surround, solid aluminum phase plug and gold spring terminals.
