Voice Coil – The construction of the voice coil is designed to maximize the speaker's power handling. The wire used is high temperature copper, wound in multiple layers on a black, anodized aluminum former. The wire will withstand high temperatures while the former conducts heat away from the coil.
Powder Coated Basket – The stamped steel baskets of the Punch Audiophile woofers are finished with a powder coat process. This good looking finish damps the basket resonance, preventing basket vibration from coloring the sound. Unrelated to the sonic perfor- mance of the speakers, but equally important, the powder coating used is environmentally friendly since no toxic chemicals are re- leased into the atmosphere during the process.
Epoxy Filled Inverted Dust Caps – The inverted dust cap provides a flatter power response and rigidity to the cone. Epoxy filling adds mass, to ensure the high performance in small, sealed boxes.
Dual Input Terminals – To facilitate
LOW FREQUENCY SPEAKER SYSTEMS
The Punch Audiophile woofers require an enclosure to achieve optimum results. The enclosure allows the speaker to operate at lower frequencies 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 of 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 frequency which is determined by the internal volume of the enclosure and the size of the vent used. The Punch Audiophile woofers will yield optimum perfor- mance in a small, sealed enclosure.
