Dayton Audio Reference RS150

The  Reference RS150 is an impressive 6.5" (16.5cm) woofer from Dayton Audio. Thanks to its versatility with an impedance of 4 or 8 ohms, the RS150 shows its strengths in various audio applications. High-quality materials such as a black anodized membrane, a resilient 6-hole cast frame and gold terminals were used to ensure the highest level of sound quality and durability. With its excellent audio properties and its high-quality, low-distortion motor, this woofer sets new standards that can take your audio experience to a new level.

• The 4 ohm impedance and 8 ohm impedance is perfect for series pairs in MTMs and center speakers
• Excellent car audio midrange/woofer
• High-quality, low-distortion motor with two short-circuit paths to reduce inductance

The Dayton Audio Reference Series sets new standards in high performance loudspeaker drivers. By using a low distortion motor system with two short circuit paths and a rigid aluminum membrane, the Reference Series outperforms drivers costing many times its price. The low distortion characteristics and high excursion ensure exceptional clarity, detail and dynamics. The woofer has a black anodized membrane, a heavy-duty 6-hole cast frame, a low loss rubber surround, a solid aluminum phase plug and gold terminals.
