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?
