I have a 125W speaker (NHT Classic 2). Should I be looking at the 80W number or 175W number to see what to get? Do I need a more powerful receiver?

Wattage is complex. In short, this receiver will have all the wattage you need. This receiver can get quite loud.Both speaker manufacturers and receiver manufacturers like to exaggerate their wattage numbers because they know it improves sales. Your NHT Classic Two speakers are 125 watts maximum. The RMS (root mean square) wattage for your speakers would be much lower, although NHT doesn't say what it is. A speaker's RMS wattage is what really matters.Likewise, this receiver's 175 watt per channel specification is an exaggeration as well. The 80 watt number is more accurate. Keep in mind that this is 80 honest watts compared to most manufacturers' exaggerated wattage. Wattage is complex. In short, this receiver will have all the wattage you need.

I'm not an expert, but I went off of the 175W per channel rating when I bought this. The speakers I got were Polk Audio TSi 400's that are capable of taking 200W of power so I knew that the receiver couldn't overpower the speakers if I cranked it up.

My receiver has had no problems. They produce about 140 watts. Sounds like your speakers can handle a lot more. Look for a bigger amp!

Don't listen to these overrated "you need at least 100W". These are very efficient speakers at 93db/W, and they don't need that much power (which is the point of efficient speakers) - at 22W @ 93db efficicency produces about same amount of sound as 60W at 88db efficiency (most people don't even look at efficiency values). They were plenty loud in my miata with a 22WRMS/ch head unit. I've also had kappas in a different vehicle with 50Wrmsx4 amp. They'll benefit from more power (not so much volume, but clearness when cranked), but not as much as other's are trying to make you believe.

To my understanding it's 25W. Mine was bought 2nd hand and runs a pair of 100 W 6 Ohm bookshelf speakers just fine, add an active sub if needed. There's plenty of settings and EQ to get you satisfied. One major surprise i had was, that you must have have a TV connected for both setup and use.

I have a Yamaha with 120 watts per channel. That seems like plenty of power.I don't know if I'd use less than 80. Good speakers for the money

It all depends on what you want. Make sure the ohms are matched right. The more bass you want the more watts you want. I have a 1200watt and its only about half way up on the gain setting. Ported box.

I have the same thing and iam using a pair of polk tsi 400 tower speakers for my home theater set up but you could use any speaker that can handle at least a 100 watts of power and have a good audio sensitivity on them at least 89 db and up! hope this help you out1 Tom

perhaps not. This is a pro audio speaker that should be matched to amps in the 250-400 watt range. Yours is only 80.

That means for best sound you should use 8 ohm speakers to match the receiver. Strange things can happen to receiver if using less than or more than 8 ohm speakers. It is not worth the try.

what about speakers with 150-watt maximum input power? I'm a novice at this stuff.

My Receiver is 125 Watts per channel. I've never even come close to full volume because the speakers are so powerful. You want to crank your stereo then go for it with no worries.

I have a single woofer in my install. No that is too much power for a single. With a double you may be fine. I put 200 watts to my woofer and it sounds great.

I went with a 4 x10 dual voice coil 160 watt. It is a 100 times better than the original 1963 speaker, but not as good as having 2 separate speakers. I'm happy with it.

It does not matter, general rule of thumb, is the lower the OHM number on the speakers, the more efficient they will be. In other words, the lower OHM number on the speaker would require less watt output from the receiver. Your receiver can output any OHM number, and the same is true for the speakers.

Well the Onkyo puts out 130W (8 Ohm) in 2 channel driven. If you want to take advantage of that power I would recommend getting a Polk Audio Monitor series system. The towers can do almost 300W 2 channel driven and sound great with a lot of power. In fact I think they are the best performance/dollars speakers out there unless you go the DIY route.

In answer to your question. The Onkyo TX-NR828 is rated 130 watts per channel @ 8 ohms, so you would have to connect to speakers that can handle that wattage. The NR828 does have a preamp. output (to another amplifier ) if extra speakers are needed beyond the 7.2 configuration. The only comment I can make about your room size is, my 7.2 setup is in a 15'x15' room and has plenty of volume/power to spare. I would recommend downloading the instruction manual from the ONKYO website for various speaker setup configurations, and specifications, along with a ton of information about this unit. Hope this helps you. Enjoy your quest. In answer to your question. The Onkyo TX-NR828 is rated 130 watts per channel @ 8 ohms, so you would have to connect to speakers that can handle that wattage.

there is no set standard for rating watts, I have sold audio gear for many years, if you go to onkyo's web page and look at specs, you will see different numbers for different ohms and frequency, all manufactures do this. Very expensive amps will double there power into four ohms, but these are in the thousands of dollar range. The size of the power supply is what really makes a difference. If your speaker package is under the $2000 price range this should be fine, I bought this for my sons system.
