D'oh!!!

You're absolutely right. Serves me right for trying to look for the switch with the sub tilted upside down and with the line-in cable plugged in. But I guess my fundamental question still hasn't changed: Based on the product specs and the variable cross knob, am I to assume that this particular sub isn't even capable of producing frequencies above 90hz?
