I have the same speakers hooked to a Denon reciever and had the same problem. I found they were sensitive to room placement. I imagine since everyones setup is different you will get mixed opinions. When I first set mine up I put them in the corners of the room and got excellant bass from them. Unfortunitly, I couldn't leave them there (door in the corner). I had to move them in from the corners, when I moved them there was a huge difference in base. I have a sub hooked up and used it to round out the bottom end. If you can't get them into corners I recommend you get a sub and start playing to find the best spot for it. Good luck.
