Paul, since the external connections seem to be correct, there's a possibility that one (or highly unlikely both)of the M80 woofers has one of the internal wires loose and it isn't working. Test the speakers one at a time on a piece of music that has good bass, and remove the connecting strips so that the speaker wire is connected only to the lower woofer terminals. See if bassy sound is heard from each M80.

Enjoy the music, not the equipment.

Paul, also make sure your receiver is in 'stereo' or 'direct' mode when you test your music cd!

If some of the drivers in the cabinet aren't working you could likely have a crossover problem. The capacitors on the crossover are very large and have to bent inwards in order to fit in the cabinet. In my M80's the soldering was broken and so the tweeters weren't working in 1 of them.
To check them, remove the plate where the speaker terminals are, pull it straight out and you'll see how the crossover is built on to that plate. Very lightly try to wiggle the capicators (big brown things)... if they wiggle a bunch then the soldering is broken. You'll need a new crossover or resolder them yourself like I did.
Don't be afraid to open up your speakers... they aren't exactly rocket science. Jut be careful not to scratch your very expensive speakers.

Yep, as the other said, it is possible you have a bad connection on the driver or whatever. After you decide if there are woofers not active, you can easily remove the screws and check the wires on the woofers in questions.

The thing that puzzles me though is that something like this would affect both speakers... I can see if one was broken, but 2 would be the epitome of bad luck.

The Crossover in his receiver has gone wonky?? Not likely but just putting it out there.
Painstakingly, isolate and replace everything and every scenario one at a time, even if you have to borrow some gear. Eventually, there has to be an Aha! moment.

Aight, I follow your guys advice.
Sirquack, I was testing my HT bass usage by checking out U-571 'Depth Charge' scene. The sub was really getting a workout, but seems like the woofers on the M80's weren't producing much output.
So, I tested out a music CD with lots of bass. I put the receiver to stereo and direct mode. This time, the sound on the midranges and tweeters were much more pronounced and I can hear sound coming from both the FL and FR speakers. But then again, not much bass was coming from the woofers. It seems like every receiver mode I put it to (including DTS, DD, stero, direct, etc), that is little bass output coming from the M80's.
So I disabled the subwoofer from the receiver so I can hear only the speakers and I heard very little bass coming from them (little, if not, none).
I had the speaker setup to large in the fronts and LFE+Main, and crossover to 80 hz.
The possibility that the speakers maybe damage or loose connections are very slim, since it not affecting one M80, but both.
I am not trying to bash Axiom, I think they make wonderful speakers, and are very good for the price. But it seems like something it wrong with my configuration.

In case you have not done it yet (and if you did, dismiss this post), you may want to contact Axiom. Their technicians are excellent and will guide you through all the steps in order to determine what the next step should be.

One idea would be to reset the receiver back to factory defaults. It is strange it is happening to both 80's. I assume you ordered from Axiom? It is unlikely, however, not impossible that the woofer section is not connected, you might unscrew the drivers and check the connections. One of my 350s was not working, and upon review didn't get hooked up at the factory. Amie addressed the issue with the production quality control line. Those woofers should be pumping. Where are the speakers positioned in the room?
