Lowther cones or AER cones (Off Topic)

Hi Retsel,

First, open baffle speakers are better off with higher Qts rating drivers.
If I changes the drivers from the 15 ohm voice coils which I now have to
one which is 4 ohms (driven by a SET amp on its 16 ohm tap or with a
higher output impedance transformer), I will get much closer to a more
appropriate Qts for the system. I can use high impedance speaker wire as
well (i.e., 31 guage) to further raise the Qts. Does this all make
sense?

No sense at all. For more bass you need a higher Q driver, for quality bass you still need a low Q driver (like the Quasar system). A Lowther or AER in an open panel will not give any bass and will only start moving a lot when the Q is made high (no control from the amp and even less when you put resistance in series!!). If you want to kill the music then feel free to increase the Q and add resistance...

If you use a bass driver in the open panel then the mid-high driver (Lowther or AER) should be low Q-ed to keep some "live" unless you want to go back to hi-fi....?

Ciao,

Bert
