OCTAVE, with the Black Box technology, offers an instrument  to optimizing the OCTAVE amplifier in respect to the speaker.
 This flexibility is a unique feature of the OCTAVE brand.  The dynamic and tonal stability of an amplifier is strongly dependent upon the  stability and capacity of the power supply, therefore the Black Box and Super  Black Box were developed as external upgrades to the OCTAVE amplifiers’ power  supply storage capacitors by increasing their capacitance by a factor of 4  (Black Box) or 10 (Super Black Box), respectively. This is a tremendous benefit  if the speaker is difficult to drive. Loudspeaker efficiency is made less  critical, while the amplifier is enabled to handle speakers with minimum  impedances as low as 2 Ohms. 
The power supply capacitance increase realized via use of  the Black Box or Super Black Box stabilizes current delivery and reduces the  impedance interaction of the load. This improves dynamic range, separation,  depth, soundstage size and articulation, rendering the musical reproduction  clearer throughout the entire frequency range. The amplifier remains unaffected  by mains variations and interferences due to the noise filtering  characteristics of the capacitors.
