The digital controllers SP 22D and SP 22Ds (subwoofers) have been designed to optimise the overall performance through a dedicated equalisation of each individual speakers.

The SP22 D and SP 22 DS are 2-input / 2-output digital signal processors designed to optimize the performance of all QUBE loudspeakers. The SP 22 D, SP 22 DS processors are easily installed in a special plug in port located on the rear panel of a QUBE power amplifier. They can also be used with FBT or other manufacturers power amplifiers, by using the rack mountable QUBE HCR 12-22 (Host Controller Rack), which provides plug in ports for two SP 22 controllers.
The QUBE Model SP 22 D is designed for use with 2-way full-range speakers: Q106, Q208, Q110, Q112, Q115, QM115 and QUBE Model SP 22 DS is designed for use with subwoofers: QS112, QS115, QS118, QS218.

Key Features:
• Frequency range equalization to optimize the frequency response and power response.
• High precision control of power delivered to loudspeakers by means of an amplifier output sensing function.
• Woofer Excursion Control
• High Pass Filtering
• Fast acting crossover roll off (steep slope)
• Delay setting on both channels to compensate for vertical misalignment
• General delay on both channels from 0.25 meter to 64 meters
• 4-position selector for 4 configuration modes: Stereo / Biamped / Bridged/ Parallel
• 2 XLR inputs
• 2 parallel XLR outputs
• 8 dipswitches to change delay settings on both channels
• 1 dipswitch (#1) for SUB/PHASE reversal selection: SUB mode activates the high pass filter when the SP 22 D is utilized to control satellite speaker(s). On the SP 22DS the PHASE mode inverts the phase providing (180degree rotation) to the subwoofer(s)
• 3 dipswitches (#2 / #3 / #4) to select the QUBE cabinet model (8 models)
