I've listened to Incogs system with only one LFM and with 2 LFMs. Let me just say that I am VERY impressed with the capability and the depth of having two LFMs hooked up. I WAS AMAZED and really like them. Makes me wish I would of bought 2 LFMs instead of 1 sub that cost more than both.
cheers,
Nert
