WOW!

M50, vp150, m3ti, qs8, & ep350.

"WOW" is good.

I even found a new reason to say "Wow" about my M50s just last night

Underappreciated but still "Wow" for those of us who like that particular type of sound.

Do you have everything calibrated as far as the sub crossover and speaker levels/delay? Then it will be DOUBLE WOW

Also, whereabouts in Florida are you?

These Axioms are very nice, aren't they!

And...editing because after re-reading your bio you state you have M60ti's but here on the post you are saying M50's. Am I right in assuming you do actually have the M60's?

I still get that WOW feeling whenever I fire up my M80s.Not bad seeing I have had them over 2 years

ditto!

PICS!!

Sirquack, Its not calibrated yet I am still in the process of learning how to. I purchased a radio shack sound level meter and Avia guide to HT. I am hoping that with teach me enough to get my system above and beyond.

Question: I seem to be getting a humming sound from the sub. I took out the ground screw which made a huge difference; however, I can still hear a little hum on some channels. Do you have any advice? I read that someone had a similar problem in this message board and Alan gave advice to that person, suggesting, many things, one of which that, a balun transformer connector would fix it. Apparently, that fixed their problem, and I am hoping something that simple will fix mine.

Also, fixed that qs8 ceiling bracket problem! Instead of purchasing a $100.00 bracket! I spent $5.00 @ Lowes and bought some galvanized pipe (12") with a 45 degrees elbow. It allows the qs8 to breath (not too close to the ceiling) and it's directionally pointed perfectly!

Brother Bob, I live in Leesburg (45 minutes north of Orlando) I actually have the m50s. I made a mistake in my bio, thanks for letting me know. Do you think there is a big difference in the m60's from m50's? Worth the upgrade?

I will have Pics up soon!!!

R, on the hum problem, the first point is whether it's coming entirely from the sub or whether it's just louder from the sub because it reproduces the 60Hz hum louder than the other speakers. Set the sub(still connected and plugged in) to off and the speakers large in your 5890 to see if the hum is also in the other speakers. If it is you may have a similar ground loop problem as Jay(500)did in his thread(and apparently solved with the Parts Express isolation transformer) and should take similar steps to trace the loop. If it appears to be that only the sum hums, it isn't a ground loop an the problem is internal to the sub. If you aren't using a polarized plug(i.e. one with a bigger left prong)in a similar polarized outlet for the sub, try reversing the plug, as Alan suggested, to reverse the polarity.

I did what you said and the loud speakers operated normally (no hum). I turned off my receiver and I could still hear the hum. ???

I don't think I am able to reverse the polarity due to the sub plug having a main ground (3 prongs).

I turned off the receiver, still humming, and then unplugged it. The humming stopped for about 3 seconds and then started back up. I unplugged all the other components which gave negative results. I unplugged the sub and plugged it into another outlet and the hum was 10x louder!!! I need help Would a power conditioner help or power strip???

Okay, then the problem isn't a ground loop, because that would also affect the other speakers, and the problem isn't reversed polarity because the three-prong plugs can only be connected with the correct polarity. If you're using a reasonably well-shielded coaxial cable to the sub, that shouldn't be picking up significant hum unless you have it right alongside a power cord(move the cable around to see if it makes any difference). Checking with Axiom might get some useful suggestions.

Is it worth the upgrade from M50s to M60s?

I dunno.....I have the M50s and couldn't be happier with them. I started with the M3s way back when, and when it was time to go with larger floorstanders in a larger room, it was a simple choice to go with the M50s.

Simple? Yeah, right....

I agonized over that one for months

In the end I went with the M50s only cause I knew exactly what the M3s sounded like and knew that I wanted something that sounded as close as reasonable to them.

Compared to the M50s; the M60s should sound a little more foreward, have a bit more midrange accuracy, be a little less forgiving of poorly recorded material, and perhaps be a little less pleasant in harsher environments.

You trade a little comfort for a little performance.

I own M60s but based on my experience with M40s and M3s I would probably be just as happy with M50s. The difference between M60 and M3 (yes, M3 not M50) is surprisingly small except for the deep bass and the difference between M50 and M60 would be even smaller...

Here are my notes from comparing M3s with other Axiom speakers. Read down to the end to get M3 vs. M60... I sure was surprised :

http://www.axiomaudio.com/boards/showflat.php?Cat=&Board=ST&Number=86248&page=&view=&sb=&o=&vc=1

I have not heard 50 vs. 60 but I would expect the following differences :

1. When playing loud music with lots of bass, the midrange would retain clarity at higher volumes on the 60 because of the dedicated midrange driver.

2. The M60 would be a tiny bit more "forward" than the M50 because the off-axis upper midrange response on the M50 isn't quite as good as the M60.

Can't believe that thread came out as long ago as March!

That thread deserves to be placed squarely within the "Reviews" section of this web site for all to read at any timeIt does a great job of placing each Axiom speaker within the range of all Axiom speakers

Thanx for bringing it back to our attention

Hum fixed! I bought a glorified surge protector. It allowed the cable to go through the surge.

When I unplugged the cable from the cable box the hum got alot louder; however, when I ran the cable through the surge protector the hum went away!!! All is good now!

Now that is odd... but I'm glad you got it fixed.

Folks, what did we learn from this ? I'm a bit confused myself...

So the hum was a ground loop problem coming through the cable feed, and entering the sub thru the power connection. The cable tuner transfered the hum from the cable feed back into the electrical system?

Hi rebulx,

Just a couple of specific questions, so I can add your experience to my list of "ground-loop fixes".
So when you refer to the "the cable", do you mean the TV-cable feed to your outboard cable-TV tuner set-top box? And did you feed the cable-TV to the surge protector, then to the Cable-TV box?

And which cable did you unplug from the cable box when the hum got louder? I'm trying to get this straight in my mind.

Regards,

Alan,
I apologize for the confusion. You are correct, I was referring to The TV-cable(coaxial). I unplugged it from the cable box, plugged it into the surge protector (annte. in), and then ran another cable from the surge protector(OUT) too the cable box.

Some of my original symptoms were:
Hum from sub only. (even after my fronts were set to large)
Hum was continuous, even with all other devices (cable box, receiver, etc.) turned off.
I played around with all the power cords one by one reversing the polarity with negative results.
When I unplugged the Coaxial cable from the cable box the hum became very loud.
After running the Coaxial cable through the surge protector the hum stopped.

Hope this helps.
