Pairings:

• A single Spike Series 2 ohm subwoofer pairs well with the ACM-1.300 or ACX-300.1 amplifiers for conservative to moderate listeners. For more provocative output, consider the ACX-600.1 amplifier.
• LC-5.1300 or D-5.1300 amplifiers provide enthusiastic output, with channel 5 being a superb match.
• For systems with two Spike Series 2 ohm subwoofers, the LC-1.1500 amplifier is recommended.
• Consult an expert for configurations with three or more subwoofers.
