NEW Dayton Audio SS15-22 15" Signature Series DVC Subwoofer 2 Ohm per Coil

Dayton AudioPart # 295-734
Model: SS15-22
The Dayton Audio SS15-22 Signature Series 15" Subwoofer strikes the perfect balance between extreme low-frequency extension and versatile enclosure performance. Designed for high-output systems, the SS15-22 combines a rigid anodized aluminum cone, dual-spider suspension, and a massive FEA-optimized motor structure to deliver clean, controlled bass even at maximum excursion. With its 3" 4-layer copper voice coil on a vented aluminum former, the SS15-22 can handle up to 1,100 watts RMS while maintaining thermal stability and resisting power compression. Whether used in DSP assisted sealed or high output bass reflex enclosures, this driver provides the output and precision needed for any subwoofer system where power, control, and durability are essential.

Key Features

  • Rigid anodized aluminum cone with indexed edge for pistonic accuracy and reduced resonance
  • Aluminum shorting sleeve, ring, and pole cap ensure linear inductance and ultra-low distortion
  • FEA-optimized motor with triple-stacked magnets delivers exceptional strength and symmetry at high excursion
  • 3" 4-layer copper voice coil on a vented aluminum former for superior power handling and cooling
  • Dual spider suspension with stitched tinsel leads for precise pistonic motion and extreme durability
  • Extensive venting through cone, pole piece, spider, and gap minimizes compression during long sessions

Rigid Cone, Maximum Control

At the front of the SS15-22 is a thick anodized aluminum cone that provides an exceptional strength-to-weight ratio. This rigid yet lightweight diaphragm resists deformation under heavy excursion, ensuring accurate pistonic motion at all output levels. The cone’s indexed edge enhances stiffness where it meets the surround, minimizing unwanted resonances. A high-roll butyl rubber surround complements the cone, allowing for extreme excursion without sacrificing usable cone area.

3" Voice Coil with Advanced Cooling

Driving the SS15-22 is a 3" diameter, 4-layer copper voice coil wound on a vented aluminum former. The multi-layer winding increases motor strength and control by maximizing coil presence in the gap, while the aluminum former acts as a heat sink to pull heat away from the coil during demanding playback. Extensive venting throughout the motor structure—including the former, pole piece, spider, and voice coil gap—ensures efficient airflow and cooling, minimizing compression even at sustained high power.

Optimized Motor for Low Distortion

The SS15-22 employs a massive, FEA-optimized, triple-stacked magnet assembly that generates a powerful and symmetrical magnetic field. This ensures the cone moves identically forward and backward, greatly reducing distortion at high excursion. Precision-machined plates with sculpted edges maximize magnetic transfer through the gap. In addition, the inclusion of an aluminum shorting sleeve, top plate ring, and pole cap keeps inductance linear throughout the entire stroke, reducing non-linearities and distortion while extending clean output into the midbass range.

Consistent Performance at High Excursion

To maintain rock-solid stability during high excursion, the SS15-22 uses a dual spider suspension spaced far apart for maximum cone and coil alignment. This design eliminates rocking and ensures reliable pistonic movement even under extreme loads. Stitched tinsel leads are integrated into the top spider to prevent fatigue and eliminate noise from lead slap, ensuring durability and consistent performance for years of demanding use.

Power, Control, Flexibility, and Reliability

With its combination of power, precision, and durability, the Dayton Audio SS15-22 Signature Series 15" Subwoofer is an outstanding choice for serious low-frequency applications. Whether used in a small DSP assisted sealed design for tight, accurate bass or a vented/passive radiator system for maximum SPL, this 15" driver delivers the output, control, low frequency extension that demanding listeners expect. As part of Dayton Audio’s Signature Series, the SS15-22 represents the perfect blend of engineering innovation and raw performance.

Matching Passive Radiator Available

To maximize the performance of the SS15-22, Dayton Audio offers the SS15-PR, 15" Signature Series passive radiator – visually identical to the SS15-22 driver. This allows you to achieve massive low-frequency extension from compact enclosures without requiring the impractically long ports that a driver of this size demands or power robbing boost from DSP assisted designs. By using a passive radiator system, you’ll enjoy the same powerful bass output as a vented design but with smaller enclosures, no port noise, and improved group delay—perfect for clean, room-shaking bass with authority.
