SEAS CA18RNX + T25C003

Maya kit components

Having finished the CNO-T25, nothing was easier than replacing the W18NX001 with the Prestige CA18RNX midbass. For some reason I couldn't tweak the CNO-T25 series crossover to work with this driver, so it actually took some time to get the shown parallel filter in place.
The CA18RNX is a long-throw, large voice coil variant of the Prestige paper cone drivers handling bass better than the CA18RLY, which holds the classic 1" voice coil.

Cabinet

The cabinet is exactly the same as for CNO mkII and CNO-T25.
