In the {{Classic}}, the {{L1 CR}} is powered by two (2) 250 Watt amplifiers. In the Model I, the L1 CR is powered by one (1) 250 Watt amplifier. Both the Classic and the Model I use a second 250 Watt amplifier to power one or two B1 bass modules. | In the {{Classic}}, the {{L1 CR}} is powered by two (2) 250 Watt amplifiers.

Although these numbers serve as a point of reference they do not tell the whole story. During the design of the {{Model I}} the impedance of the {{L1 CR}} was lowered. As a result of the lower impedance, a single 250W amplifier now powers the system to within 1.75 dB of the max SPL of the {{Classic}}. Several other changes were made to the signal processing and acoustical sections to further reduce this small difference. Particular attention was paid to this change and many A/B comparisons were conducted by Bose to confirm that there was no significant audible difference between the two systems. | Although these numbers serve as a point of reference they do not tell the whole story.
