Product Research
Features
Sealed Box: Hertz recommends a sealed enclosure volume of 15.3 liters (0.54 ft³). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.
Ported Box: Hertz recommends a sealed enclosure volume of 18 liters (0.64 ft³) with one 62mm (2.4") diameter x 155mm (6.1") long port, resulting in a tuning frequency of 43 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.
