Vandersteen 3A sigs, whats wrong here.

Check the Treble and Mid-Range Controls on the back If these are set to +dB positions it will be accentuate these areas . The Bass will seem weak .

These speakers will produce decent Bass when Set-Up correct .

Yes, I did check the speakers and they are all working. As well as the level controls on the x-over. To test the rest of my gear I hooked up an older pair of Polk LS9 floor standing speakers and they had more bass. You can tell that the 3's will go deeper. But at a much lower level compared to everything else that is coming out of them??
I am still confused...

did you mean Kimber 8TC?

They have a very lean bass in my experience

for instance AZ Satori has much more of a warm balance

my two cents based on these wires in one system...

I had them years ago.They are a hard speaker to set up.Try tilting them back.You can raise the front with some books till you get them sounding correct. Hope this works out.

The Vandersteens are not a lean sounding speaker, actually they err on the warm side. The Kimber 8TC is a good match for the Vandersteens, perhaps they are a touch lean but that's not a bad thing for the Vandersteens. Positioning is important, use the guidelines in the owners manual. I see from your System photos you had your previous speakers close to the wall, while that might emphasize bass that is not the best location for Vandersteens. Ideally they will be at least 2 feet from the rear wall, more is better. Setting up the tilt of the speaker is detailed in the manual, but has no effect on bass. The tilt gets the upper frequencies just right for your listening distance and ear height. I would suggest checking all of your conncetions to make sure you don't have the woofers out of phase with each other, i.e., the connection of one speaker is the reverse of the other. That will kill the bass. Having done all that I would play bass heavy music and walk around the room listening to the bass level. You may find your room has a lot of bass nodes where cancellation or reinforcement are taking place. Speaker and listening seat placement may have to be adjusted to make sure you are not sitting at one of those nodes. Good luck!
