What is the purpose of a bandpass box?
So how do they work? A bandpass enclosure is, by definition, simply a sealed enclosure with an acoustical filter in front of it that serves to limit the upper-end of the driver’s frequency response. This natural limiting of the high-frequency response of the system makes the selection of midbass drivers critical.
What’s the difference between bandpass box and ported box?
The difference between a bandpass and a regular ported box is that in a ported box, the port is in the same enclosure as the rear of the driver, whereas with a bandpass the port and the rear of the driver are in separate enclosures. Bandpass boxes are ideal for genres like hard rock, metal, hip-hop, and reggae.
