Brand NEW! Including 90 Days USA Factory Warranty. The RSS265HO-44 10" High Output Reference Subwoofer from Dayton Audio is designed for high power handling and extremely low distortion. A small enclosure requirement allows it to be used in car audio and space limited home audio applications. Key Features Dual 4 ohm voice coils for many wiring options Extensively vented motor eliminates compression and allows quiet excursion Extra-thick black anodized aluminum cone for maximum rigidity Triple shorting-ring motor for ultra-low distortion Parameters optimized for small enclosures Highest quality materials throughout for long-lasting performance Dayton Audio's 10" RSS265HO-44 High Output Reference Series subwoofer is purpose-built for moving lots of air, extreme power handling, extremely low distortion... and it does it all with an extremely small enclosure requirement! The minimum airspace optimization of this driver makes it perfect for car audio automotive applications and limited space home audio applications. To minimize distortion, three copper short-circuit paths are built into the motor. This reduces second, third, and intermodulation distortion to levels only attained previously by expensive, exotic subwoofers. A side benefit is reduced energy storage and inductance, making the RSS265-HO-44 a very musical subwoofer. In fact, frequency response remains very flat up to 500 Hz. Additional features include: a heavy gauge black anodized aluminum cone that resists deformation from extreme air pressure levels found inside of small sealed enclosures, a fully ventilated motor for reduced power compression, a rigid cast aluminum frame for structural integrity, and a tough rubber surround that won't wear down over years of use. Dual 4-ohm voice coils allow for a wide array of wiring options. As with all Dayton Audio subwoofers, you receive a full 5-year warranty. Designed and engineered in the U.S.A.
