Axiom Home Page Forums General Discussion Home Theater axiom vp150 center

I generally have my center about +2 db from the mains. Sometimes +1. It varies sometimes depending upon the movie.

I know it seems like alot but I find Dialogue to low.And it does blend great.vp150 6 ohms 400watts,M60 8ohms 250 watts.Maybe It takes more power to move vp150?

Wow...um...that's a LOT of watts. I'm playing with 75 watts a channel (unlikely I'm using them all). Trust me...watts is not what you need to focus on. Decibals is where your focus should be. Perhaps the best place to start is to pick up an Avia: Guide to Home Theater DVD and a Radio Shack SPL meter. The Avia disk is good for information as well as having a number of tests you can run to fully calibrate your speaker setup.

Not to add any confusion, but I generally run my center channel a couple of decibals hotter than recommended (or at least matched). Sometimes it comes down to what sounds better to you

Feel free to ask any questions you may have. The people here in the Axiom forum love to help out people getting into new systems.

Naw Pete - I kept her. We are doing a whole "menage a audio" thing.

The only "issue" that I ever had with my VP150 was when I had it sitting directly on top of my Mits 65" RPTV without the little rubber bumpers on the bottom. The sound seemed to transmit through the bottom of the 150, and into the TV. The sound coming through the screen was not good. It could be described as "hollow", I guess. I put a board across the top of the TV (it's sitting on some folded up rags at each edge of the TV to keep the weight off of the center of the TV), and put the VP150 with bumpers in place on top of the board. Problem solved.

Calibrated with Avia, MY vp150 is at -2dB, and the M60s are at +2dB. For some movies, I bump the 150 to -1dB.

The reason that the 150 has a higher wattage rating is that it's lower resistance allows more current to flow.

If you apply 10 volts to a 6 ohm load it will draw 1.6 amps. Since power = I(amps)*E(volts), it will consume 16 watts of power. (by converting electrical energy into sound waves)

Apply that same 10 volts to an 8 ohm load, and you get 1.25 amps. The power used would be 10v * 1.25a, or 12.5 watts.

This means that the VP150 will use 22% more power than an M60 when you send them both the exact same 10v signal.

That's a good point. My MX-700 remote is set up to allow me to adjust each speaker and the sub. After calibration (and remembering the settings), I will adjust the sub, VP100 or QS8s by a decibel or two (amazing difference for that small of an adjustment) depending on the source material. Afterwards, I set it all back to where I started. Works pretty well.
