Rockford Fosgate Punch P1 Series 15" Subwoofer

The Rockford Fosgate Punch P1 15" Subwoofer is a single-voice-coil, 15-inch woofer built for enthusiasts who demand deep, controlled bass in standard sealed or vented enclosures. Kevlar fiber reinforced paper cone and VAST technology increase surface area by up to 25% for more output without a larger box.

• Size: 15" woofer designed for substantial bass output in common car enclosures.
• Power Handling: 250 Watts RMS / 500 Watts Max, enabling confident performance with properly matched amplifiers.
• Nominal Impedance: 2-Ohm or 4-Ohm variants (depending on version), affecting how much current your amplifier must deliver and how you wire the speaker in a multi-woofer setup.
• Voice Coil: Single 2.0" voice coil for power handling and heat dissipation during high-output playback.
• Cone Material: Kevlar fiber reinforced paper cone for stiffness and linear motion under excursion.
• Basket: StampCast basket with integrated spider venting to reduce resonance and improve cooling.
• Magnet: 60 oz magnet providing strong motor force for dynamic bass response.
• Xmax: 9.0 mm peak excursion, enabling substantial cone travel in the right enclosure.
• Surface Area & Efficiency: VAST technology increases cone surface area up to 25%, boosting displacement in the same enclosure size.
• Sealed/ Vented Volumes: Sealed box volume 1.58 cu ft (44.7 L); vented box volume 2.66 cu ft (75.3 L).
• SPL: 87 dB @ 1W/1m; 90 dB @ 2.8V/1m, giving a reference for expected output with typical amplifiers.
• Mounting & Fit: Mounting depth 6.98 in (177.2 mm); cutout diameter 13.85 in (351.8 mm).
• Terminals: Dual 10 AWG compression terminals for flexible, high-current wiring.
• Special Features: Extended pole piece and bumped vented backplate for improved cooling and mechanical stability.
• Trim Ring: Rubberized ABS trim ring with optional grille for premium look and edge protection.
• Protection: Protective PVC textured magnet cover helps guard the magnet assembly.

• Warranty: 1 Year Warranty.

In a real install, the P1 15" excels in both sealed and vented enclosures, delivering impactful bass with tight control thanks to the stiff Kevlar cone and reinforced coil assembly. The VAST-enabled displacement works with standard box volumes to maximize output without increasing enclosure size, while the rugged construction and dual terminals support reliable, high-power operation. The included trim ring and optional grille help integrate the look into any cockpit, and the 1-year warranty provides peace of mind during aggressive listening sessions.
