Axiom Home Page Forums General Discussion Advice from Axiom Owners VP150 Possible Problem

I was just about to start a thread with the same question when I saw this. Now that I have Axioms all round again (60s, VP100, QS8s) the sound is very consistent between speakers and the surround modes for music sound great again (although I still think I slightly preferred the M2s for music).

When I run pink noise around the speakers, though, the VP100 still sounds quite different from the rest (probably caused by the fact it has a shelf 6" above it and a TV below it ?) but there are also fairly significant differences between left and right channels for the same speaker type (eg. left and right M60s sound different, for example).

I haven't had time to swap the speakers and see if the sound moves with the speaker (it probably won't -- placement in the room is not symmetrical) but before I mess around with that has anyone else heard the same thing ? Talking about a fairly significant difference in pink noise sound between left and right main or left and right surrounds.

Note -- I'm not even thinking about the surrounds right now since one is hanging on a wall and the other is still stacked up on a pile of soup cans

Guys,

While the pink noise is playing, change the delay (distance) settings for the center channel. You can hear the changes in tone as you change the setting. If you can't get it exact, and your reciever has only 1 foot adjustment steps like my HK630, move the center forward or backward a few inches, then repeat the delay/pink noise test.

Also, make every effort to align the actual center with the phantom center created by the front speakers. I found that if the two "centers" do not align with each other, it will mess with the sound. I guess most would describe it as "muddy". An easy way to test the side to side location is to play music and switch from stereo to DTS, DPLII, or Logic 7 on the fly. When the imaging (particularly, the location where the lead singer's voice is coming from) stays pretty much the same, you have it right.

Pink noise contains some energy in the lower octaves that the VP series can't cover as well as the main speakers can, so the pink noise will never sound exactly the same. This is not a problem. The 2 will sound identical when playing frequencies that they can both handle equally as well.

I almost sent my VP-150 back until I found out what the heck was going on (which took hours and hours). No way will I give it up now. The center is the one speaker that guests always make positive comments about when they come over to watch movies. When we listen to stereo music, they always think the vocals coming out of it sound fantastic as well. That is until I pull the cable from the back of it to show them that the M60s are placing the singer there without any help...

The quicker you eat that soup, the sooner that QS8 get's hung on the wall!

Wow, that's a really informative post. When we get that center... It's going to be harder than I thought, isn't it?

>>The quicker you eat that soup, the sooner that QS8 get's hung on the wall!

I already bought more soup. What I need to buy is wood screws...

They're difficult to find on Canadia, huh? Must be tough living on an island...
