rnathans00 Posted March 19, 2012 Report Share Posted March 19, 2012 I have a classic set of Allison Model One's which I've had since 1979. (A new pair of Allison Two's, purchased in 1978 were stolen in transit to my new place in Washington, and these were the replacements.) In the late 1990s I replaced all four woofers with replacements from Allison in Kentucky, but always thought they were a little "bassier" than the originals. Reading much later about the "new" versions of the Allison series, I learned they were some 3 db more efficient. I started thinking, "Perhaps I got woofers intended for the *new* Allison One, and that's why they were putting out more bass. It was just a theory however.After recently fixing the crossover of a recently acquired pair of CD-6 cubes, I felt bold enough to test that theory, but foolishly without checking with others who might have known better. I decided to disconnect one of the two woofers in each speaker. BAD IDEA, for two reasons.First, not having the schematics I didn't realize that disconnecting one woofer disconnected the second one as well. That was bad enough, but in reinstalling one of the woofers (heavy suckers!), it slipped and a section of the foam surround tore. (It's ve-e-ery delicate!) So in the process of testing a faulty theory I damaged an otherwise perfect driver. I can't "hear" the damage, but when the time comes to sell the Allison One's I'll have to disclose the flaw - or have them fixed and chance damaging the driver again when I reinstall it.
