Power hungry speakers

Is, "NHT makes a good speaker" not an opinion? Followed by, " I have not had experience with them."

annunaki · Mar 12, 2004

Yes, it is an opinion, with those words being followed by "based upon reviews I have seen."

zumbo · Mar 12, 2004

It is the power at that distortion level.

Again, as you put more of a load on an amp, the distortion increases.

annunaki · Mar 12, 2004

You cannot increase the load on the amp as the load is the 8 ohm speakers. You can turn up the volume but all you will add is more distorted power.

zumbo · Mar 12, 2004

I WILL NOT give advice based on another opinion besides my own.

zumbo · Mar 12, 2004

Every time you add a speaker to an amp, the load increases. WHY DO YOU THINK THE DISTORTION INCREASES?

zumbo · Mar 12, 2004

annunaki : You cannot increase the load on the amp as the load is the 8 ohm speakers. You can turn up the volume but all you will add is more distorted power.

More funny statements:

annunaki · Mar 12, 2004

That is true. What are you trying to tell me. That the rxv2400 will give you more than the 32.4 watts rms x 7 20hz-20khz, .1% thd, all channels driven simultaneously at 8 ohms. It cannot happen, the amplifier is already at its maximum CONTINUOUS output at .1%. If you go higher distortion increases and decreases sound quality.

zumbo · Mar 12, 2004

Not sure about the actual number, but I THINK the human ear can not hear distortion below 2%!

If the amplifier is already at continuous power at .1% (or any distortion figure) distortion this statement is totally true. (this is what I was insinuating). Why is the truth funny. The speaker is the load on an amplifier, not the volume control.

All of this power issue is why I chose to use 4ohm speakers. I get more out of my amp this way because it is under more of a load!

annunaki · Mar 12, 2004

With a sine wave at higher frequencies (above 500 hz or so) most can hear 1%.

Big deal, you still are not getting the power you were promised.

Did you also know that an amplifiers control over a speaker decreases as the load increases? 8ohms to 4 ohms. The thd also rises.

zumbo · Mar 12, 2004

I believe that is what I have been trying to tell YOU! That is why performance drops (distortion increases) when more speakers (load) are added to the equation!

annunaki · Mar 12, 2004

Why did you not simply state when "when you go from 8 ohms to 4 ohms the power increases." The way you were stating it sounded like you can simply adjust the load on the amp when ever you would like. Either way your receiver is still overated, and that is nothing agianst you.

annunaki · Mar 12, 2004

That is also why rating surround receivers the way Yahmaha does (only two channels driven) is "bad news bears".

zumbo · Mar 12, 2004

What I said was, "every time you add a speaker to the amp, you increase the load on that there amp"

Look, The simple fact is this:

Your review source plainly gave a better score, in every area, to the Yammy. I did not bring this reviewer into the discussion, you did. 'NUF SAID!

Bye bye now, alrighty then!

annunaki · Mar 12, 2004

I have to go home now any way. The AVR 325 and the RX-V2400 were both rated by home theater. Which is a cridible source. In no way did I try to find a review that lied about performace. They are both good receivers. All I was trying to state is that when all channels are driven on a Yahmaha and a H/K, the H/K has a MUCH STRONGER amplifier section. And a person does not get the power they supposedly are supposed to get with a Yahmaha. Good day.

Actually, I'd be a little cautious when reading rags like HT-magazine.  The have rated prior 2000 series yamaha's in the past with higher power output than current models.  Its highly questionable, considering the newer 2400 model has larger caps, transformer, and is built better.  Given that they recently rated the 2400 with significantly less wattage, it makes one wonder what the boys over in their lab are smoking.  Also, their figures used to match up more closely with sound and vision's, but now they don't...go figure...

jdueitt,
As you duley noted, there are many more variables and factors involved with an amplifier's true output, despite a given "power consumption" label on the back.  The retention/storage of the capacitors and their voltage wasn't even mentioned in the long-winded debate that this thread endured.

best,

You folks seem to be forgetting that evening doubling amplifier power only gives a slight amount of difference in the audio output available to the speakers.  In short doubling amplifier power most certainly does not double perceived soundlevels at the speakers.  You would notice virtually no (or very little) difference between the loudness of a 100 watt amp and a 150 watt amp.
