Axiom Home Page Forums General Discussion Stereo Out with the new and in with the newer

lol, your easy to love mojo! Your my speaker persona through and through!!!

A couple of nights ago, I had guests over and we ended up watching the first two Die Hard movies. I was sitting directly across the right active LFR and one of my guests was sitting across the left. We were both 14 feet away from the center image and two seats away from the MLP. Recall I no longer run a center. My setup is 4.5 with QS10s as sides.

Anyway, I was very surprised with both my guest and I perceiving a very strong, natural center image. I also found images didn't collapse into the active LFR close to me but rather in the volume behind it lending to diffuse effects. The active LFR furthest from me diffused its images really well too rendering them unlocalizable to the speaker.

Last time I assessed the center image away from the MLP, it only persisted one seat away. Two seats away was an absolute no go. I've since tried with other material and the center image is holding steady two seats away.

I don't know what to make of this.

I figured I'd post this here for reference.

I was taking some measurements with my active set-up today. I've been meaning to do this for a while to satisfy my curiosity. I was hitting 100dBC peaks at 14 feet away. This is very loud for me. I'd never listen this loud. My Onk was at -5 and channel levels are calibrated pretty close to 0.

I had my actives playing wide open and no sub. My DMM read about 5VRMS max on the woofers, 3V on the front mids and half a volt on the front tweeter. I didn't measure the rears. I can't measure true voltage or SPL peaks. I estimate maybe 8W average max total.

I don't know what the peak power was but if I work back from the SPL I was measuring and the spec'd in-room active LFR sensitivity, I was hitting 50W peaks per channel. So pretty close to 9dB peaks above average. I was listening to Bob Marley Legend on tape via RCA cables that are 10 feet long and 40 years old.You know...the ones that are as thin as a hair and a depressing gray color.

Of course all this could be wrong because my equipment is laughable but it feels right.

Check out williston audio labs on youtube. You are using far more power than your multimeter suggests.

I'll check it out. Yes, I do know...very well. Measuring voltage and current that sways all over the place (crest factor and frequency diversity) is tricky business.

OMG! Two more 500s are coming! Two more 500s are coming!!

I don’t know Mojo, did you just get your pay check and accidentally press the button ... or is Axiom sending you an early birthday present for being the most enthusiastic being on this side of the galaxy?

I bought more so I can upgrade them when the smart subs are introduced.

I'm also working on the Model C. Wait 'till you see that! Poor James Tanner. His Model T will look like a joke. It will be time to upgrade, Slimpikins.

hmmm ... do they go under water or are the "smart" because they like to stay dry?
If that's the case you might already have the advanced "smart" version but just don't know it.

A smart sub crawls to the ideal acoustic location in a room. Multiple smart subs cooperate with each other and sit their butts down in mutually agreed upon locations.
