Owners of standard CS2.4 speakers may be interested to know that the
only internal difference that makes a 2.4SE is the use of ClarityCap
SA film capacitors. DIYers can make this upgrade or better by
substituting the more recently introduced ESA range.
. I don't have a
schematic, but during that time Thiel was
purchasing 14uf and 28uf values. They may have been bypassing these
with 1uf polystyrene caps. You should be able to confirm this by
inspecting the crossover.
Since then we have surpassed SA by two
generations-- ESA and now CSA. For that application I suggest CSA/250V
or, space permitting, our top CMR/400V model.
You should inspect the
board to be sure. The configuration is likely 14uf in parallel
with 1uf(=15uf) and 28uf in parallel with 1uf(=29uf). If this is the
case, then you could (1) replace the 14uf and 28uf values and leave the
stock 1uf polystryrene caps in place, or (2) replace both the high
values and the paralleled 1uf caps with 15uf and 29uf.
It is advisable to look carefully at the circuit before ordering anything.
Looking at Partsconnexion and Madisound, I don't see these values from Clarity (or Mundorf), especially as a close-up of the CS2.3SE crossover indicates 630 V. Are Thiel's values a special order?
