Remember when CV, B&W and Infinity made the same speaker?

There was a curious time in box speaker history, when it seemed three companies settled on nearly the identical form factor. It used a vertical array of mid/tweeter/mid, with a big woofer below.

Am I the only one who remembers this? I'm thinking of the B&W 808 and I can't remember the other models.

Has the trail mix gone to my head?


Should have been more clear, this would have been the mid-late 1980s.
its just an MTM. Its been used by more than three companies.
