I'm still unsure we're talking about the same thing.
auto-transformers usually allow to vary the level starting from 0dB and adjusting to minus 2dB, minus 4dB etc. If switching back from minus 4dB to minus 2 dB means increasing, then OK.

Again, I have inverted my autotransformers so that the nominal 0dB is increased by +1,5 dB, +3dB etc. up to +7,5dB (multiple taps allow up to +15dB but it becomes dangerous for the amp), i.e I am boosting the original signal to increase the response in the UHF, where most 2" drivers drop off normally.
