What We Think

A great, well-known speaker tamer.

Manufacturer's Description from Other

With my attenuator the speaker impedance is not critical and here is why. As long as the amp matches the attenuator and you don't bypass the attenuator the impedance will be closer than you might think. At the most minimum attenuation level -3db using an amp set at 8 ohms and using an 8 ohm attenuator and a 16 ohm cab your amp will see less than 12 ohms. At -6db the amp will see 10 ohms, at -9 db it will see 9 ohms, at -12db it will see 8.5 ohms nearly a perfect match with a 16 ohm cab. The math works the opposite way as well so if you use a 16 ohm attenuator and the amp set to 16 ohms and an 8 ohm speaker with the attenuator set at -3db the amp sees 12db. At -6db the amp will see 14 ohm, at -9 it will be 15 ohms, at -12 it will see -15.5 ohms and the farther you turn the volume down the closer it gets to 16 ohms. The reason is the attenuator is taking a larger and larger percentage of the load as the volume is turned down and it gets closer and closer to 16 ohm. Another thing to remember that the impedance rating is not fixed it fluctuates. That rating is arbitrary for comparison purposes. And only reads the rated impedance at 400hz. The actual impedance fluctuates from 6 to 80 ohms on a 16 ohm speaker depending on the frequency. Now what is important about this is the amp is constantly affected by this altering impedance and that is what is meant by a reactive load and why a reactive load sounds much more natural than a resistive load.
