[SonocusEric]

so i built troels' W18 crossover version 2 as shown here,

but built a TQWT for the 18W/8434G00 using the calculator here

HiFi Loudspeaker Design

do i have to mod the initial trap value for 18w? if so how?

thanks

Why the first ? The first is the lowpass ( the L ) plus some EQ ( the RC parallel to the L ) for the high frequencies.
The second is the impedance flattening network ( RC ) and the third is a RLC network centered on some peak in frequency response; probably, this is where you should point, as a different load might change cone behaviour .
