I would be surprised if anyone did order Axiom's and was disappointed with them. Heck, if I had just ordered the M80's alone, I would have no qualms with keeping them and would be quite happy with them. Neither the M80's or 6T's had any weaknesses I could really fault them for, they just play to slightly different strengths which is up to the listener to decide what they prefer.
As for the MWF-15, unfortunately I do not have a very good comparison for it, this is my first foray into subs of this price/performance. My old sub is a dual 8" Yamaha which did well enough to bring neighbors over to ask me to turn it down with music (single family homes with 20' in between), but didn't really have much of a 'wow' effect with movies.
Out of the box the MWF had a hum when I connected it up (the old sub was not grounded). MLS was kind enough to help me troubleshoot it, and we determined it wasn't the cable connection, and when I told him I could hear devices being turned off and on through the sub we guessed it was poor electrical wiring in the house. He was going to send me an audio filter for it, but a few days later I realized the hum was actually caused by an svideo connection from receiver to the tv for the OSD menu. So now I just leave that disconnected when not needed. However I still hear things being turned off and on in the room through the sub, not a big deal as I can control the order of how things are turned on. The biggest thing is I hear a 'pop' from the sub whenever the mini fridge's condenser kicks off in the room. I probably have a bit too much in this room...
As far as performance, I've been really happy with how well it blends in with the towers for music. My old sub could get kind of muddy, this one seems much cleaner. I haven't done a lot with movies yet, waiting for this weekend when I get the surrounds...
But I did watch Darla tapping on the glass in Finding Nemo, over, and over, and over...
That was a new experience for me. The MWF did have a little extra noise during that scene, but the older sub just sounded weak and plain horrible in comparison. From what I've gotten from other people is that that scene is pretty tough even on good subs. I also watched most of War of the Worlds, and that was pretty cool too. My couch is a foot and a half off the back wall, the sub is next to the couch firing into that space, so it's kind of fun to 'feel' it. I've only got about 2 spots, maybe 3 if I rearrange the room, the sub can go, and that's my preferred spot so it's there for now. I haven't gotten around to figuring out frequency responses yet and measuring them. I plan to watch a few of the LotR movies this weekend. Again, I don't normally listen at insane levels, around 100db is good enough for me (I've seen some people pushing these to 110 or higher).
I have noticed that when I turn it up loud enough, my ear facing the direction of the sub needs to be popped once in a while. I was wondering if that means I need to get a second one for the other side of the room to even it out...
Sorry for rambling...and threadjacking...
