Description
15" 2-Ohm SVC Punch Subwoofer 250W RMS, Kevlar Fibre-Reinforced Paper Cone, VAST, Nomex® Voice Coil Collar, Extended Pole Piece, 10-AWG Nickel Push Terminals.
Product Overview
The Rockford Fosgate Punch P1S2-15 is a 15" 2-Ohm Single Voice Coil (SVC) subwoofer rated at 250W RMS the largest format in the Punch P1 subwoofer range. The 15" cone moves significantly more air than the 10" and 12" P1 models, producing greater bass output and lower frequency extension in comparable enclosures suited to high-output builds and installations where maximum bass presence is the priority.
All confirmed Punch P1 construction applies: Kevlar fibre-reinforced paper cone, VAST surround (up to 25% increased cone area), high-temperature voice coil with spun-laced Nomex® reinforcement collar, extended pole piece with bumped vented backplate, StampCast basket with integrated spider venting, 10-AWG nickel-plated push terminals, rubberized ABS trim ring with grille insert provision, and protective PVC textured magnet cover. Optimised for sealed and vented enclosures. Sold as an individual unit.

Features & Benefits
-
15" Cone — Maximum Air Movement in the P1 Range — The 15" cone moves the most air of any driver in the Punch P1 lineup — producing the greatest bass output and lowest frequency extension. A 15" subwoofer requires a substantially larger enclosure than a 10" or 12" driver — confirm enclosure dimensions and available installation space before purchasing.
-
250W RMS — Confirmed 250W RMS sustained power handling.
-
Kevlar Fibre-Reinforced Paper Cone — Kevlar aramid fibres reinforce the paper cone for improved stiffness and breakup resistance, with paper's natural damping characteristics.
-
VAST — Up to 25% increased effective cone area at the same basket diameter.
-
Nomex® Voice Coil Reinforcement Collar — Spun-laced Nomex reinforcement at the voice coil-to-cone junction for thermal and mechanical durability.
-
Extended Pole Piece and Bumped Vented Backplate — Extended pole for increased Xmax; vented backplate eliminates air spring compression.
-
10-AWG Nickel-Plated Push Terminals — Heavier gauge for lower contact resistance at 250W.
-
StampCast Basket with Integrated Spider Venting — Motor cooling during sustained operation.
-
Rubberized ABS Trim Ring / Grille Provision / PVC Magnet Cover — Clean installation finish with optional grille.
-
Sealed and Vented Compatible — Both enclosure types confirmed.

Frequently Asked Questions
Why choose a 15" subwoofer over a 12"?
A 15" cone moves substantially more air per stroke than a 12" driver — producing more bass output and lower frequency extension in a matched enclosure. The trade-off is that a 15" enclosure requires significantly more internal volume and physical space, and the driver itself is heavier. A 15" installation suits builds where boot space, dedicated subwoofer enclosures, or vans and trucks provide the required room.
What enclosure volume is required for the P1S2-15?
Enclosure volumes for sealed and vented configurations are not confirmed in the supplier data. A 15" driver requires considerably more net internal volume than 10" or 12" drivers — confirm the Rockford Fosgate recommended volumes from the official P1S2-15 datasheet before building or selecting an enclosure.
What amplifier power is appropriate?
250W RMS at 2-Ohm. Confirm the amplifier's RMS output at 2-Ohm before purchasing.
Is a grille available?
The rubberized ABS trim ring accommodates an optional grille insert. Confirm the compatible grille part number with Rockford Fosgate.
What is VAST and how does it benefit the 15" cone?
VAST (Vertical Attach Surround Technique) attaches the surround vertically at the cone edge — increasing the effective radiating area by up to 25% compared to a conventional surround attachment at the same basket diameter. For a 15" driver, this translates to meaningfully more air movement and output than would otherwise be available at the same physical footprint.
