Pairings:

• A single Space Series 4 ohm subwoofer pairs fabulously with the ACM-2.300 or ACX-300.2 amplifiers for conservative to moderate listeners. For higher output levels, consider the LC-1.800.
• LC-5.1300 or D-5.1300 amplifiers deliver rich, robust output, with channel 5 being an excellent match.
• For systems with two Space Series 4 ohm subwoofers, LC-1.800 is recommended.
• Consult an expert for configurations with three or more subwoofers.
