[QUOTE="Tzs503gp, post: 1015975, member: 19443"] Your mention of a ?fast speaker?. Again, you wouldn?t know until you?ve actually experienced a fast speaker. Due to the mechanics of ported, or bass reflex speakers, you miss approximately half a wavelength of sound, around the port tuning frequency. To illustrate- the music signal transients to a 30hz tone. The woofer follows that signal, responding very closely to that transient, but due to the mechanics of a ported speaker, the air behind the woofer takes half a full wave to start moving. You don?t hear that first half of the wave. That makes a slow speaker. Other box designs such as sealed and TQWT designs do not suffer that effect. Those are generally regarded as ?fast?. You hear the transient at the time it was meant to be heard, not one half wave later. [/QUOTE]
