tomic601 - one thing to check is the coax drivers, be sure your 2.3s have the upgraded drivers - sn#4567 was the first to have been converted to these at the factory per Rob. I bought my 2.3s used, lower serial number, but luckily the coax (and xover) had already been upgraded. The upgrade gets you the same coax driver and xover as 2.4s, if I understood Rob correctly.
Here's Rob's full response to one of my questions re this upgrade -
There were two versions of the CS2.3. New style,
and old style. The new style began at serial numbers 4567. The new style
consisted of having two magnets on each of the coaxial drivers. The old style
had only one magnet. Both versions used ceramic magnets, and the CS2.4
incorporates Neo magnets. Much stronger magnet 10x. The CS2.4 coax cannot be
used with the CS2.3 properly. The coax rebuild is $250 each, plus shipping, and
can be rebuilt in either version. The new style coax had a two part change to
the crossover network as well. You can remove your coax for inspection, and
tell whether it is a double ceramic magnet or only one, like the old style. If
you need to rebuild both coaxes, then the associated crossover parts are free.
Let me know how I can help.
