All roads lead to music
I saw these available and could not pass them up.
I ordered my first real system from Illinois Audio in the 70s. This included a pair of A-10s. Before it shipped, I came into some extra cash, called them and changed it to A-50s (those are regrettably long gone). This is the first time I've heard these. Playing now with subs and sound great.
I've wondered why these were the only classic Dynacos that used XO parts on the woofers. Not just a coil, but cap-coil. Maybe the SEAS 6.5s had a peak that was not an issue in the 10s. I plan to run Omnimic tests on the drivers, with and without XO, and on my beat up Polk Mon 4s also. Maybe even do some A/B listening tests. Should I go hi-low...
...or side by side? (BTW, the enclosures are almost exactly the same dimensions.) Can't do true A/B with speakers because they can't be in the same place at the same time, and because level matching is undefinable (IMO) when the DUTs don't have the same frequency response, but those are trivial issues for informal testing.
I will post some results when I got 'em.
