In Reply to: Why are ported designs ubiquitous? posted by Peter on December 22, 2009 at 18:19:36:
A 2 cu ft 2nd order sealed box with an F3 of 30hz can only be 0.18% efficient (84.55dB).
A 2 cu ft 4th order vented box with an F3 of 30hz can only be 0.36% efficient (87.56dB).
A 2 cu ft 6th order vented box with an F3 of 30hz can only be 0.90% efficient (91.54dB).
I sold AR (decades ago). The EV Interface A (1974) was a smaller, much better sounding speaker. It also played louder at 30hz, and was more efficient. It was a 6th order design. I still have a pair in my livingroom (the cabinets are a bit beat-up).
The B&W 800 series are a more modern example of a 6th order design that audiophiles will recognize (I also sold B&W).
