Marantz wattage

[cptrave]

I have the Marantz 7012 below are the specs. I have two channels connected directly to the Marantz, my Center channel and 1 height speaker (Atmos) . My center speaker is Klipsch RP-450C and my atmos speaker is Micca M-8C 8-Inch. How do I know what output (wattage) the Marantz is providing to my speakers? The speakers are not bi-wired or bi-amped.
I know it's 2 channel driven.
My other speakers are connected to Emotiva amps.

Marantz

Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 110 W

Power Output (8 ohm, 20 Hz - 20 kHz, 0.05% 2ch Drive) 125 W

Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive) 165 W

Power Output (6 ohm, 1 kHz, 10% 1ch Drive) 235 W


Klipsch RP-450C

Frequency response 58-25 kHz +/-3dB

Sensitivity 97dB@2.8v

Power handling 150w/600W

Nominal impedance 8 ohms compatible

Crossover frequency 500Hz/1500Hz


Micca

Woofer: 8" Mica-Polypropylene Cone, Butyl Rubber Surround

- Tweeter: 1" Pivoting Silk Dome, Ferrofluid Cooled

- Crossover: 12dB/Octave with Compensation Network

- Frequency Response: 40Hz-22kHz ±3dB

- Impedance: 8 Ohms

- Sensitivity: 90dB 1W/1M

- Power Handling: 100 Watts (Each)

Based on the specs you posted, That is the one that gives you the best idea of how much power is available to each of the two speakers you have hooked up to it's power amps. That doesn't mean that much is being sent at any given time, but it IS what the Marantz is capable of providing should it be called for.

Dont worry about it.

As I look at that again, that spec on the second line doesn't make sense, when compared to the first line. The THD number would generally go up when more power was available, that's showing it going lower at 125 w/ch then the identically speced power output at 110 w/ch .

Something about those specs still doesn't seem correct, it has more power at less distortion than an A-500 does ?? I can't see that to be true.

Check this screenshot of the product page I just took, below the power ratings there is a spot that says "70% Guarantee" with a check mark, is that saying they will guarantee it will output 70% off the stated specs listed, if that is what it is I find that hilarious, just another way of false advertising

I found something within an Audioholics review of that Marantz that explains the "70%" gurantee:

Here at Audioholics we at least want a full bandwidth, two-channels driven into 8 ohms under 0.1% THD+N. It's good to see Marantz list the 2CH full bandwidth power rating first on their spec sheet and they also offer a 70% guarantee.

When we pressed Marantz on the meaning of their 70% guarantee, they reported the following:

"SR7012 Rated Power Output: 90.5W x5ch (72.4% of 125W) at THD+N = 0.05%"

I will just add that with 97dB rating on that center channel the marantz should have no issue at all driving that speaker. At just 1 watt of power that center is crazy loud. Anything above 100dB is almost going to damage your ears if you listen it it too long.

[cptrave]

That's crazy about the 70% guarantee. And yeah it's definitely enough power to drive the center speaker.
Thank's for your help guys.

You don't seem to have power hungry speakers so I bet it sounds awesome.

++ to what DYohn said.

You'd have to measure the voltage and current, or one of those and the impedance, to know the power into the speakers. Here is an online SPL calculator that will give you a rough idea of your power needs: myhometheater.homestead.com/splcalculator.html

Yes, they sound amazing. I have to watch my movie collection all over again. And my wife loves to listen to music. And my teen daughter wants to have a party just to use them and show off.

Great, thanks I will look into this
