Also, in considering how much current a speaker uses at a given sound level, speaker sensitivity has to be taken into account, and a speaker such as the M80 with slightly above average sensitivity can actually require the same or even less current for a given sound level than an 8 ohm speaker of less sensitivity. For example, if the M80 required 50 watts for a brief peak, the current required would be (square root)50/4=3.53 amperes; for the same brief peak a speaker of 3dB less sensitivity requiring twice the power(e.g., the M3)at 8 ohms would similarly require (square root)100/8=3.53 amperes.


John,

I think that might explain something that I’ve pondered to some degree, but never curious enough to pose the question as a stand alone post. But now that you mention it, hijacking this thread seams appropriate.

A while back my remote decided to pin the volume on the 3808 that I’m using as a pre/pro. The center channel of the 5X200 amp tripped off, but all other channels stayed lit. By going off your example of the M80 vrs M3, would it be a logical assumption that my twin M22 center arrangement draws more current than the M80 mains?

Sure, Mike; this would especially be the case if at that particular moment the center channel material that would have to be played by the M22s was louder than what the M80s and other speakers were playing at the time(hope that you had some ears left afterward). So, at least three factors come to mind: possibly louder material, slightly less sensitive speakers, and possibly even lower net impedance at the frequency in question with the center speakers being run in parallel.

Enjoy the music, not the equipment.

LOL... I'm just glad I wasn't watching an action movie when it happened. I believe it was just crappy cable SD. It probably had more center dialog going on at the time, but I don't recall exactly. I was more interested in turning the volume down at that particular moment...it was VERY loud.

I have since then set the Denon max volume control to -5.

How about you get the free t-shirt, and they can send me some free speakers?

To get the free speakers you need to babble incoherently for 10k posts or so. ;\)

Wow. Sadly, I'm not even a quarter of the way there.

The mind boggles at having to deliver (and you guys having to suffer through) more than three times as many posts as I already have.

Considering that back when, we used to have little informal contests about who could top the boards (ie, make the most recent post in every forum), it's not quite as hard as you think. But definitely as incoherent.

Found out the auto calibration was pulling -6db off the sub, not to mention there was a setting that was limiting the LFE output (presumably to keep people with wimpy subwoofers from blowing themselves up). That Elite 94TXH has so many freaking settings it boggles the mind. Manual calibration with an SPL meter is in my near future.

I actually had to take 3 pictures off the wall because I was afraid they were going to fall off. I'm a happy camper now with the EP500 set below 1/2 way on the level dial. Its truly amazing what some tweaking can do.

I'm also very impressed with the M80's, although this took some effort to get there. I discovered the tweeters weren't working on one of them. I pulled out one of them and discovered it's terminals weren't insulated and were touching the metal shield on the back. So I wrapped them in tape. That still didnt' work so I pulled the crossover out of the back and found that one of the large capacitors was loose on the PCB. Looks to me like they bent it over to get it to fit and broke the soldering loose. (this would be the large brown rectangular capacitor on the right hand top PCB). I just put a small piece of tape on it to test my assumption and it started working... maybe someday if it gives me problems I'll get the soldering iron out. I'm dissapointed that I had to do that type of work on the speaker to get it working... but it was worth it. The clarity is amazing and even with the volume up they put out gobs of sound without effort.

I think I'm about even now with the folks at Axiom. While I was a fool for not properly tweaking out my system before judging sound quality. They let me down on the quality control with a torn subwoofer, non working tweeters and cabinet damage. Thankfully all is well and I couldn't be happier with the end result.

I was going to try to photoshop my head onto an animated superman gif, with fluttering cape -- but then I remembered that I was at work and that's a waste of company time. \:\)
