Our Sonic Sommeliers Recommend the Following:

A single Spike Series 2 ohm subwoofer pairs well with the ACM-1.300 or ACX-300.1 for the conservative to moderate listener. For more provocative output, seek out the ACX-600.1.

Planning to enjoy the enthusiastic output from one of our LC-5.1300 or D-5.1300 amplifiers? The potent power delivered from the output of channel 5 is a superb match. Bon appétit!

For system designs utilizing two Spike Series 2 ohm subwoofers, we recommend the LC-1.1500… Scrumptious!

Longing after even more low frequency output? Planning to include three or more Spike Series subwoofers in your system? Consult an expert at your favorite authorized AudioControl dealer, or visit for more system configurations that deliver ravishing audio reproduction.
