The spike height and propogation delay tilt for the watt upper unit are based on table values in the manual based in part on ear height from the listening position and distance back from speakers. Read your manual.
Wilson Sasha Spike adjustment help?
I would like some help with regards to the Watt head adjustments. Wilson provided spikes with 4 different heights to tilt the back of the module. I found using no.3 too lean but getting too much bass with no.2! I wondered the best sound should come from the height between 2 and 3, so I used a coin at the buttom to raise the number 2 spikes a bit and it works. Yet, I think this is not the best way so I wonder anyone have played around with those adjustments and if any after market spikes with custom height can be found? cheers.
