A cd player should work with the sub, Alan has mentioned doing this to check a sub before. The rest of you have pretty much covered it, well done. My first thought was as Peter mentioned some sort of dynamic compression is being used on the yamaha to keep the range low which would explain only the most extreme LFE making it to the sub.
I would also suggest calling Axiom to see what they say and any possible help/suggestions they may have, you may find a new amp on its way and the problem solved by this weekend.

I suggest you pull the amp off the back to see if one of the cables is loose Mel N.

As Dr.Horse suggested, . . . *giggle* +1 Did I miss another good thread? You never know when stuff takes a left turn around here.

Well this one is into the second page and still seems to be on track. Are you guys slipping?

My two test discs that I'm moving forward with are Pirates of the Caribbean 2 for DVD and Oscar Peter Jazz Essentials for CD. The DVD has lots of LFE and a deep soundtrack and the CD features Ray Brown with a lot of bass that goes down below a deep C (~65 Hz) so I'm sure that my source material is delivering the right content.
RE Sir Quack: I unplugged over night on the off change that something may reset, but this evening the difference in performance is not statistically significant (I'd say identical, but technically I can't back that up)
RE Dr. House: I bumped the subwoofer level all the way and I get output with the sub volume as low as 12 o'clock, but at 50%, that seems awfully high for the minimum threshold. It is certainly not consistent with past performance where the level was set at three ticks vice 10. I still do not believe I am getting all I should be off the CD.
RE Peter Chenoweth: I'm satisfied that the cables and connections are correct. I hadn't considered the night mode, but confirmed that is is not enabled. As Jakewash noted, Alan Loft has mentioned patching the CD player directly to the sub input in the past for fault finding purposes.
RE Onn: I pulled the amp and the internal connections are tight
I believe that the CD I've been using is my best source materiel for experimenting with. Knowing the music, my sense is this: My sub has two issues. First, there is an issue with the sub cross over setting or other LPF which is interfering with performance. Second, the is a gain issue such that typical/normal/reasonable levels are not being produced.
I will contact Axiom tomorrow, but I'm still ready to try anything else you can come up with.
Thanks for the support

Thought I'd chime in here as well. My EP350 volume is up @ 75% to get the proper depth in the low end. I had some of placement issues at first (as some of you know). I too felt as thou I wasn't getting the performance at that volume level, but JC @ axiom assured me 75% volume was totally normal. I do have a large room as well. I still "kinda" feel like it should push more low end at that volume level (my yamaha trim is set to +2, XO at 80hz). I just don't have anything to compare it to in the same class as the EP350.
The thought of returning it (still within 30days) goes thru my head so I can try a different sub to compare, was thinking about the HSU MK3. Worst case is they both will perform about the same and I can always return the MK3 and reorder the EP350. Both are close to the same money, I would be surprised if the was a "huge" difference. If there was, I would suspect I too have an amp issue with my EP350.
It's a tough decision because I'm really not sure if it's even under performing or not. Some here tell me they have their 350 volume no where near my level & get plenty of low end.
BTW, when connecting a CD player to the sub, what exactly is that supposed to tell me? Should the sub be cranking @ 75% volume with a CD player? What am I listening for to tell me my Sub is performing normally?

My setup is in my basement family room and the room isn't that big. In the order of 10x22x7 with a couple of bumps to break up the long walls. About 1400 sqft.
If I had to push the volume to 75% because that's what my room required, I'd be satisfied with that or move on to a different sub if I was concerned.
In my case, it's not a matter of not enough to fill the room at a given setting, it's that I'm getting nothing until I hit what I believe to be an unreasonable high lower threshold.
