So Amir currently has in his possession a Beolab 9 speaker which was provided for him to measure. However, due to the significant demand/backlog of other more relevant/contemporary speakers which are also in the queue, it's unclear if taking the time and effort to measure the Beolab 9 would be...

Do you think there’s any possibility that the speaker itself is out of spec/damaged?

Some interesting remarks by Geoff Martin on B&O's sound design philosophy: https://archivedforum2.beoworld.org/forums/p/7924/71862.aspx#71862 https://archivedforum2.beoworld.org/forums/p/14149/123726.aspx#123726

According to a forum post on DIYAudio, B&O does appear to prioritize power response over frequency response, which may(?) explain some of the percieved wonkiness in the measurements. https://www.diyaudio.com/community/threads/cloning-a-3200-speaker-for-400.163015/post-2115934

There's some interesting info about the 20s archived on the old Beoworld forum (Geoff Martin was responsible for tuning the speaker I believe, and some of these posts actually from him): https://archivedforum2.beoworld.org/forums/t/14149.aspx?PageIndex=1 There's also another post I'm trying to...

I was wondering if anyone know where I could find a used pair of Beolab 5s or 20s in the states for a reasonable price available to be shipped to Washington. Thanks!

I was looking around and found an interesting looking link to a document regarding the Beolab 9 that was formerly on the B&O website. Unfortunately, the link was long dead when I tried to download it, but somehow, B&O customer support managed to locate a copy, which they sent to me. Perhaps it...
