Is there a chance of blowing my speakers with this config?

[srinivas1015]

My current Speakers: TSi300 (Fronts, sides, rears), CS20 Center, DSW500 sub

They're rated at 150 watts.

I'm planning on getting the Marantz Sr 6011. The single channel drive is rated at 220 watts. Does Audyssey calibration count as a single channel drive?

I don't want to blow my speakers.

Hi Srinivas,

Higher the Watts Clipping is low.So Nothing to worry about matching the AVR to speaker,Just make sure you dont crank the volume (I dont think you would do in HT).

Speaker Rating > Amp\AVR- Risky
Speaker Rating < AMP\AVR- No problem until you go beyond listening levels
Speaker Rating = AMP\AVR - Slight Risk at high volumes.

Above is general one, I have driven 100w Speaker with 25 W Amp ( T22) without any trouble.

My speaker rating is 150 Watts. The receiver is rated at 110 watts when driving 2 channels at 8 ohms. This isn't an issue, right?

I usually listen at -17 dB (reference volume) and the maximum I go to is around -9 dB. This counts as normal listening levels, right?

A lot of people will tell you that higher power amp is a good thing, so long as you are careful with the volume control. This is fine if you are forced into such a situation. But there's always a risk that someone else in the house may have accidentally turned up the volume, e.g. to clean them. I have blown my speakers like this.

On the other hand, if the amp is not powerful enough to drive the speakers, it can cause clipping in the audio.

Therefore, if you are about to buy a new amp, I believe you should choose one that is in line with your speaker capacity. There is still a chance of blowing the speakers at very high volumes with very dynamic music, but the degree of care you need to exercise is significantly lower.

Best wishes!

Are you going to drive just one speaker?
In any case these specs are not useful at all.
The useful specs are "Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 110 W".
So you are fine. No risk at all.

No, I won't be driving just one speaker. But what about Audyssey? The test tones won't count as driving one speaker, right?

Don't worry, your equipment will stay perfectly safe.
The only possible risk you run is if you playback something with very high gain and turn up the volume on your avr so high that the amp starts clipping.

Under normal conditions, you run no risk with these settings

yeah.. as long as you don't listen too loud it's ok..

my pioneer sc-lx90 susano are rated at 140w per channel and i'm driving my 250w klipsch rf-7 ii speakers at reference level without any problems.. i'm running a 5.2 channel all channel bi-amped configuration..

As you can see, all responses by fellow FMs include a qualification such as 'so long as you are careful with the volume control', ' so long as you don't play it too loud', etc. That's something to think about. How sure can you be that someone else will not accidentally turn up the volume? Does your amp have an inbuilt volume limiter?

This is a general comment and may not apply in your case to a 5.1 ch setup.

Two days back, my 4 year old was on the laptop connected to the 7010 to tv playing video games. I was preoccupied with my phone and did not notice him turning the volume full on. Amp was on pure direct mode thankfully with my sub turned off. My 81 year old mom was in the room. When the game came on with the accompanying sound I literally dropped my phone and jumped to reduce the volume on the receiver. Mom was shaken but composed.

Now I make it a point to use the volume limiter on the receiver always. Its not just about blowing your speakers or receiver.

I have set mine to - 40 on startup and 0db max volume limit. With kids around its more of a necessity than a best practice

In the receiver you can digitally limit max volume. That solves your problem

Wattage ratings on AVRs are at best misleading. Remember "1000 watts PMPO" boom boxes??? Efficiency and speaker impedance will state more on if the clip or not. Lots of posts on this forum on that subject.

Now also marketing people try to fool people by giving...

1. Wattage one channel driven. Useless.

2. Wattage clipping THD+N 1% or more.

Easiest way to find real wattage capacity is to see AC input power consumption and weight of the AVR

How do we correlate the AC power consumption with sound output power?

Output power is coming from input power.

Max input AC power consumption gives rough idea of the capability of the power supply built in.

I know that a more powerful audio amp will consume more electric power. My question is if there is something like a formula to correlate the two

Input power = output power / efficiency.

Considering very good efficiency of 90% i.e. 0.9, you will realize output power is always less than input power.
