When I was listening to a Reggae CD (one song in particular) that I'm very familiar with and has a lot of bass. The bottom end was virtually nonexistent at one point in the song where it's just bass. I'm comparing my EP500 to my previous paradigm which had far less output but I noticed the bottom end. On Saturday I will be calibrating my system using a calibration DVD. Aside from the DVD calibration settings, what else can I do to improve the bottom end?
My Denon AVR3801 doesn't have a adjustable Hz setting on it. My front speakers are set to "small" which defaults the receiver to 80 Hz.
Going from memory the settings on my sub are as follows:
crossover-bypass volume-between 8 and 9 o'clock phase- 0 trim-flat

Try the fronts set to large and run the cd in direct mode. I noticed a little more low end running like this on my 1804, in stereo mode some of the low end disappeared.

With my fronts set to large won't it take more base away from my subwoofer?

Just going through my manual. On my denon should I have my LFE setting set to just LFE, or LFE + Main? It says when LFE + Main mode is selected, the low-frequency signal range of channels set to "large" are produced simultaneously from those channels and the subwoofer channel.
This sounds like the optimal setting. Can anyone else clarify this?
Thanks

You are getting the LFE channel plus all bass to your speakers set to large and the sub. This setting helps to even out the LFE in the room, IMO.

Thanks for your help Jason. In the manual it says exactly that. It was suggested by a Axiom representative to set my left/right channels to small. I think I will try setting them to large as you suggested and changing the LFE to LFE + Main.
Any other input would be greatly appreciated.

You got it right. With the fronts set to large and the sub set to LFE+Main, you've got all the front bass going to both the fronts and the sub.

I am running my M80s as large and LFE as norm which means the LFE channel and all signals below the xover of speakers set to small is being sent to the sub but everything except that in the LFE channel is sent to the mains.

Welcome to the world of peaks/nulls in a room. Most likely your dealing with sub placement a room acoustic issues. Personally, I still would recommend using the small settings and let the sub do the work it should be doing as it can move more air.
Sub placement, especially with only one sub, can be a long life struggle. Room treatments, correct sub placement, room dimensions, etc. are just a few links in the chain.
I'll have to look at your pictures again to see if I can come up with any further suggestions.

Thanks for the help. I don't really know where else to place my subwoofer.
