SEAS CA18RNX + T25CF001

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.
