Rockford Fosgate Punch RFP-1215 Subwoofer
PUNCH RFP-1215 Dual Voice Coil, 15 inch Subwoofer.
Description
Rare! Brand new in the Box. The opportunity exists to own one of these legendary subwoofers, brand new and 100% operational, these are most likely the last ones on the planet that are still NEW.
(*Note - there are Multiple Subwoofers available, the price is for one)
The Punch Dual Voice Coil woofers are low frequency drivers designed primarily for use in small, sealed or vented enclosures. The dual voice coil design allows low impedance loads to be configured for optimizing the performance of Punch Power 50.1 and 50.2 amplifiers. By utilizing the latest materials and construction techniques, we are able to offer a speaker with optimized low frequency response while requiring a minimum of operating space.
The Dual Voice Coil Woofers use a stamped Cold Rolled Steel basket which is rigid and lightweight. The basket is finished in a corrosive resistant power coated applied process used in many automotive applications. THE RESULT: A lightweight and rigid woofer.
The cone material used is spruce pulp paper. This provides the necessary combination of weight and strength and allows high levels of output without cone break-up. The cone is treated with a water resistant PolyVinyl Acetate (PVA) Emulsion which increases the cone rigidity and lowers distortion. THE RESULT: Increases cone rigidity and lowers distortion.
The santoprene material is resilient to temperature variations and provides a consistent support necessary for the linear motion of the speaker cone. In addition, the inherent damping capabilities eliminates the transmission of sonic disturbances between the cone and the frame of the speaker. This greatly improves the clarity of the speaker's frequency response. THE RESULT: Improves speaker's frequency response.
The speaker's linear compliance is balanced through the use of a “proprietary” flat spider design. A flat spider provides symmetrical control of the voice coil through its cone excursion. Linear cone excursion reduces harmonic distortion for improved sound quality. THE RESULT: Reduces mechanical distortion for better sound quality.
Powder coating has long been the industry standard for durability in protective metal finishes. A dry powder (non-aerosol) is electrostatically applied to the metal and “baked on to provide a hard “shell-like” finish. As an additional benefit, powder coating is the only finishing process that releases no toxic chemicals into our ozone. THE RESULT: A durable and “earth friendly” metal finish.
The use of the inverted dust cap serves to increase the cone rigidity and improve the power handling by forcing more air through the voice coil. THE RESULT: Increases cone rigidity, smooths frequency response and prevents your friends from feeling obligated to invert them for you.
The voice coil former is black, anodized aluminum for highly efficient thermal transfer. This allows winding high temperature copper wire in multiple layers for improved efficiency. THE RESULT: Improves power handling by efficiently dissipating heat.
The pole piece has been extended to provide a more linear magnetic field for the operation of the woofer. This lowers distortion and provides the woofer with better low frequency response. THE RESULT: Lowers distortion and provides better low frequency response.
The back plate has been stepped deeper to allow the woofer more excursion without bottoming out. This enables the speaker to be used in a smaller enclosure. Additionally, the back plate is vented with a radiused aerodynamic back vent which efficiently and quietly circulates cool air around the voice coil. THE RESULT: More excursion and increased power handling.
The dual voice coil design of the speaker allows a variety of impedance loads to be configured. A single woofer can be wired for a 2Ω load and a pair of woofers can be wired for either a 4Ω or 1Ω load. These configurations allow a multitude of amplifiers to be used with the Punch DVC. THE RESULT: Allows multiple wiring configurations.
