Our Sonic Sommeliers Recommend the Following: A single Spike Series 2 ohm subwoofer pairs nicely with the ACM-1.300 or ACX-300.1 for the conservative to moderate listener. For more substantial sub bass, seek out the ACX-600.1.

Planning to revel in the plentiful power from our LC-5.1300 or D-5.1300 amplifier? The liberal output delivered by channel 5 is a fantastic fit! Bon appétit!

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