Some AT-40s have a rear-panel midrange attenuator. These oxidize. Rotate them back and forth 50 times with the speaker off, then use DeOxit. If they crackle, bypass them with a fixed resistor (the factory midrange level is actually the best setting).

Given the specs (94dB sensitivity, 8 ohms nominal, 125W peak), here is the ideal power matching:

This speaker is highly efficient (approx. 98 dB sensitivity ). This means it requires very little amplifier power to produce loud volumes.

The rear level adjustment dials often accumulate dust over 30 years. If turning the dials causes crackling sounds or causes the tweeter to cut out, a quick spray of DeoxIT cleaner inside the potentiometer will usually fix it. Conclusion

Understanding a spec sheet is one thing; knowing how the AT40 behaves in a living room is another.
