Point Five Percent

Caleb Mower is hand soldering point-to-point wiring on one of our crossovers. He's using two different types of solder: one chosen for the upper frequencies, the other for the lower. Meanwhile, most other highend manufacturers are wave-soldering their components to printed circuit boards, which are inherently poor conductors of high current music signals.

All crossovers use capacitors and inductors; even the best typically deviate from their rated values by +/- 10 percent. Left unaccounted for, the measured performance of each crossover—and hence each loudspeaker—will vary by an audible margin. Wilson Audio dictates that the loudspeaker you buy sounds indistinguishable from the product Wilson designed. That's why we spec our speakers more than an order of magnitude tighter than the industry standard.

And that's why, when Caleb measures his finished crossover, it will match the reference within plus or minus .5%.
