I've had a set of Allison Ones since 1979. In the 1990s, given "surround rot", I replaced all the woofers with drivers from the revived Allison then down in Kentucky. I found I was getting more bass, assuming it was because these were "new", rather than flawed like the ones replaced. Or evidence of my "flawed" acoustics.
Reading about the enhanced (and much more costly) versions of the One, Four, etc. from that short-lived revived Allison, I noticed reference to their higher efficiency compared to the originals. I've long wondered if I was using a woofer intended only for the newer Allison One, rather than the original.
Recently I acquired a pair of Outlaw bookshelf speakers - similar to Snell's K-7 and actually made for Outlaw by Snell. Really nice (and no longer available as Snell is no more), and even more natural sounding than my Ones. So again I have to wonder about those woofers. Assuming they *are*, in fact, not a proper match for my original Ones, is there a way to tone them down to better replicate the behavior of the originals?
