Our Sonic Sommeliers Recommend the Following:

A single Space Series 4 ohm subwoofer pairs fabulously with the ACM-2.300 or ACX-300.2 for the conservative to moderate listener. For more copious output levels, pursue the LC-1.800.


Planning to relish the rich, rotund output from our LC-5.1300 or D-5.1300 amplifier? The plentiful power delivered from the output of channel 5 is an excellent match. Bon appétit!


For system designs utilizing two Space Series 4 ohm subwoofers, we recommend the LC-1.800… delectable!


Seeking an even more superb sonic signature? Planning to include three or more Space Series subwoofers in your system? Consult an expert at your favorite authorized AudioControl dealer, or visit for more system configurations that deliver an abundance of amplitude.
