Test Results

1. Use DSX Shay Decoders with 220µf capacitors
2. Compare speakers to one another one at a time
3. Set the CV 50 (Volume) for each speaker to the value listed in Column 3
4. Score 1 point below for better speaker in each comparison, 0 points for the other speaker (in bordered white area)
5. To minimize the number of speaker connection and disconnections, compare each speaker in turn with the speaker in the second column on the left.
