yep my kenwood excelon 6x9s are the oval kind with two tweeters in the center. they hit lower than just the mid-base regions. i got one of those frequency test cds that covers the whole range all the way down.. my system sounds plenty beefy down below 30 Hz... i think the bottom rating from the factory is either 25 or 28 Hz.. just lettin ya know it can be done! peace,
Jake
