Dayton Audio Reference RS180S-8

Meet the RS180S-8, an impressive 6.5" (16.5cm) mid-woofer from Dayton Audio. This speaker is part of the Dayton Audio Reference Series and has the ability to outperform drivers costing many times its price. The RS180S-8 features a low-distortion motor system with two short-circuit paths and a rigid aluminum diaphragm, allowing it to deliver a clear and dynamic sound. Furthermore, the RS180S-8 is known for its strong bass performance, which is made possible by the long-stroke motor and suspension. Another advantage of this mid-woofer is its ultra-low magnetic stray field, which allows the unit to be positioned extremely close to CRTs.

• Long-stroke motor and suspension for strong bass performance
• Subtle high-tech look as a cosmetic statement
• Ultra-low magnetic stray field enables extremely close proximity to CRTs
• Designed and manufactured in the USA

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 cone, the Reference Series can outperform loudspeaker drivers that cost many times their price. The low distortion characteristics and high excursion ensure exceptional clarity, detail and dynamics. The woofers have a shielded motor system, a black anodized cone, a heavy-duty 6-hole cast frame, a low loss rubber surround and a solid aluminum phase connector.
