Sub Cross Over Help

Need a little help from you guys running subs. Let me start off with what I have. Power amp, Krel FPB400 CX, KCT pre amp, Bryston CD player, B&W 804s's with a Rel R328 sub. I've been doing a lot of research and reading and learned a great deal from you guys on this site. As of right now I have the sub crossed over at 40hz. The sub is next to the left speaker 18 inches from the corner and 8 inches from the back wall. The speakers are 10 ft apart and a fot from the back wall with my 55 inch plasma TV in the center. My listening distance is 10 ft from the speakers and the room size is 17 x 14. I've used a RTA with a 40hz tone to match the sub with my full range speakers. Everything seems to sound extremely well. The imaging and sound stage is superb. Only thing I've noticed depending on the music I play. I sometimes have to turn down the gain on the sub by 5 clicks, which I'm sure is normal. The gain on the sub sits at 16 clicks from zero. Let me know what you guys think and what I can do to improve my system if any. Please let me know.

I did reposition the sup and It sounds the best in the corner with good bass. I can go a little lower with the X over.

Thanks guys for your help on this. Timlub It the nail on the head. I did move the sub out of the corner witch did help. I dont have so much Bondry boost like I did. The X over is at 35hz. The only thing I notice is when I play hard rock like Rush Then I go to play something like Yellow or something that has a lot of low Bass in It. I will have to turn down the gain a little. I'm still playing with things to see If I can get better. I'm trying to get the sub to play good bass at the right gain. No matter what disc I play. Something tells me this is very hard to accomplish. As it stands right now the sub blends in extremely well with my 804's. Much better then it did before when the sub was in the corner. Any other advise would be helpful. Thanks
