    Sealed is Not Acoustic Suspension in Loudspeakers
    A trip down memory lane with names like Advent, Bozak, Electro-voice, KLH, Acoustic Research etc., small Hi-Fi stores in Cambridge MA, who were eager and happy to demo their wares to students (poor like me) who they knew could never afford them. I recall listening to the AR-9s and KEF-105s side by side. I liked the KEF for clarity, image and balance and my friend liked the AR-9s for the base. Interestingly, Klipsch name is not mentioned for horn loading.

    How do you all opine on the topic of sealed vs ported in this article?

    Acoustic Suspension is a specific alignment invented by Henry Kloss and Edward Villchur. "Sealed" is infinite baffle. Now I'll read the article. :)

    Yeah, it's got to have a very soft suspension so that the air spring is the main support.

    Yeah, had this discussion with someone at an audio meeting a month or so ago. I learned something, or maybe I was just reintroduced to some things I'd forgotten along the way :wink:
