Dayton Audio Reference RS180

The  Dayton Audio Reference RS180 is a high performance 6.5" woofer/midrange speaker tailor-made for your audiovisual needs. With its high quality build, low distortion and excellent excursion, this speaker offers outstanding sound quality. Included features such as 4 ohm and 8 ohm impedance make it the perfect choice for series pairs in MTMs and center speakers. This woofer/midrange speaker sets new standards in terms of sound dynamics and detail, making it able to outperform competitors that cost several times more. 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
• Excellent car audio midrange
• 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 spring terminals.
