  • 2022 Speaker Competition

    After I demoed my Duettas in the Jam Room yesterday, someone (?) asked me a question about the size of the twin mass-loading ports I used, with a specific concern about possible port noise due to the ports' sizes. I wasn't able to completely answer that question until I reviewed my modeling results at home. Yesterday I told that person that the peak port air velocity with an input of 30w/1m, that created a system output of 97-98 dB SPL, was not an issue. My modeling results show that with this input to the Duettas, the peak air velocity modeled at 4.2% of the speed of sound, or ~14.5 m/s, and occurred at a frequency of ~32 Hz.
