AeroVent™ Pole Piece – The AeroVent™ provides ventilation for the voice coil for improved power handling. The AeroVent™ is aerody- namically shaped to allow passage of large amounts of air without constricting the air flow which can cause whistling or turbulence noise.

Suspension – The suspension holds the cone to the basket and suspends the voice coil in the magnetic gap. The surround, which supports the cone, is made from a dual laminate foam which minimizes edge deterioration. The proprietary flat spider design maintains linear motion of the voice coil even at high listening levels.

Voice Coil – The voice coil is wound on a large diameter anodized aluminum former for highly efficient thermal transfer. The large gauge high temperature copper wire allows operation at high power levels.

Cone – The cone is made of a heavy and rigid paper material which allows for very low frequency response and resists deforming when driven at high power levels.

LOW FREQUENCY SPEAKER SYSTEMS

The Punch Power Woofers require an enclosure to achieve optimum results. The enclosure allows the speaker to operate at lower frequen- cies with improved power handling. The two most commonly used types of low frequency speaker systems are acoustic suspension and bass reflex. The acoustic suspension enclosure, commonly referred to as a sealed box, relies upon the changing air pressure in a tightly sealed chamber for its operation. The bass reflex, commonly referred to as a ported enclosure, uses a vent inserted into the box which takes over for the speaker at a desired tuned frequency which is determined by the internal volume of the enclosure and the size of the vent used. The Punch Power Woofers will yield optimum performance in a small, ported enclosure.

USING THE PUNCH POWER WOOFERS

Speakers are built in different sizes to optimize their performance in different frequency bands. Crossovers are used to route the different frequency bands for each speaker. There are two operational types of crossover: active and passive. An active crossover is an electronic filter which is placed before the amplifier and separates the signal fed to different amplifiers in the system. A passive crossover is positioned

PWR-415, PWR-412, PWR-810, PWR-812, PWR-815 specifications

Rockford Fosgate has long been a trusted name in the audio industry, and their PWR series amplifiers are designed to deliver superior sound performance, driving the best experience for audio enthusiasts. The PWR-812, PWR-815, PWR-412, PWR-415, and PWR-410 models cater to different requirements, offering a variety of power ratings and features suitable for various applications.

The PWR-812 is an 800-watt, 2-channel amplifier that operates at a power rating of 200 watts RMS at 4 ohms and 400 watts RMS at 2 ohms. With its Class D circuitry, it provides maximum efficiency while minimizing heat generation. The amplifier is equipped with adjustable crossovers, allowing users to tailor their sound settings according to their preferences. Its MOSFET power supply ensures robust performance and durability.

Moving on to the PWR-815, this model is a powerhouse, delivering 1500 watts across 2 channels. It is ideal for users looking to achieve higher volume levels without sacrificing clarity or detail. It features an impressive dynamic range, enabling it to reproduce the most demanding audio tracks with precision. The PWR-815 also leverages advanced thermal management features, which ensure reliable operation even under the most strenuous conditions.

The PWR-412 and PWR-415 models provide a balanced approach to power and control. The PWR-412, a 4-channel amplifier rated at 50 watts RMS per channel, is perfect for driving multiple speaker configurations. It supports extensive connectivity options, enabling seamless integration into existing audio systems. On the other hand, the PWR-415 elevates performance with its impressive 75 watts RMS per channel output, designed for those seeking a more robust sonic experience.

Finally, the PWR-410 amplifier is a 4-channel model that offers flexibility with its power output of 75 watts per channel at 4 ohms. It provides advanced features such as fan-cooled heat sinks for efficient thermal management and variable low-pass filters, allowing for fine-tuning of the audio signal.

All the amplifiers in the PWR series incorporate premium components and cutting-edge technologies, ensuring they meet the high standards that Rockford Fosgate is known for. With their robust build quality and thoughtful design, these amplifiers are well-suited for both casual listeners and serious audiophiles alike, making them a perfect choice for enhancing any car audio system.
