Dayton Audio's Reference Series RSS315HFA-8 12" subwoofer utilizes the same
low-distortion design as the rest of the series, but provides an 8 ohm
alternative for increased connection and impedance-loading options.
Key Features
Extensively vented motor eliminates power compression and allows quiet
excursion
Lighter-weight black anodized aluminum cone minimizes moving mass
2-layer coil for reduced back EMF
Triple shorting-ring motor for ultra-low distortion
Optimized for large enclosures
Highest quality materials throughout for long-lasting performance
The Dayton Audio Reference Series subwoofers take the quality and
performance of the much acclaimed RS line into the subwoofer realm. As with the
rest of the Reference Series, the main focus of the RSS315HFA-8 12" driver is
ultra-low-distortion. Second, third, and intermodulation distortion are kept
extremely low by utilizing three magnetic short-circuit paths within the motor
structure. A durable aramid fiber spider and extensive venting throughout
provide quiet and uniform excursion. The black anodized cone, rubber surround,
and custom basket give this driver a unique, high-end look. Choose this High
Fidelity (HF) version for home speaker systems when your priority is clean, low
bass and you are not restricted by cabinet size.
