If you have five speakers, plus a subwoofer, that's 5. Those systems typically have three front speakers, left, center and right, and two surround channel speakers, plus the sub. Dolby Atmos or DTS: X systems have a different layout, they might have five front speakers, left, center and right, two height channel front speakers, and two side or rear surround channel speakers, plus the sub. You'll see this listed as 7. Once you've selected the number of speakers you have, next select the size, large or small, of each speaker in the system.
Floor standing tower speakers or big bookshelf speakers are large, all other speakers should be configured as small. When in doubt about size, opt for small. Next, look for the crossover setting option on the speaker setup menu.

If your speakers have 4-inch or smaller woofers use a Hertz crossover, and any speakers with larger woofers than that can use an 80 Hertz crossover. If you're not sure about your speaker's woofer sizes, use a Hertz crossover setting. Large speakers typically don't need crossover settings. Next grab a tape measure and measure the distance from each speaker and the subwoofer to the main listening position, aka the "sweet spot.
How to use your AV receiver's speaker calibration
Next, we need to balance the "channel level" of each speaker in the system so they're all equally loud. Look for the "Test Tone" setting on the speaker setup menu, which runs tones through one speaker at a time. These meters all have settings of their own, select "C" weighting and "Slow" response. Sit in the sweet spot , and hold the mic or the smartphone up near your face, and hold still during calibration. Now start the receiver's test tone sequence running through one speaker at a time at a medium loud level on the meter -- we'd suggest 75 decibels dB.
Adjust the receiver's master volume control to get the tone level up or down to the same 75 dB.
When running the test tones which sound like a whooshing noise or beeps , the room should be as quiet as possible, so turn off your air conditioner, and shut all the windows and doors. Take your time and repeat the sequence a few times, fine-tuning the level of each speaker with each pass of the test tones. When using your system, if you find you have difficulty hearing movie dialogue go ahead and raise the center channel volume to 78 dB. That way the dialogue will stand out a little more clearly in the mix, but feel free to add a few more dB if it's still not clear enough.
Don't worry, no harm will come to the speaker! In the same vein, raising the level of height speakers 3 dB above "level" can help with immersion.
How to use your AV receiver's speaker calibration - CNET
While speakers are pretty straightforward, a subwoofer takes a couple of extra steps. This is mainly because unlike the other speakers it's a powered unit and comes with its own volume control. First, set the subwoofer's volume knob halfway up, and then set the sub's volume level with test tone as you did for the speakers, and the meter reading 75 dB.
That's just a starting point. Sound meter accuracy with bass readings in manual or auto setup can be hit or miss, so you may have to raise or lower the sub's volume later on. You can do so with either the receiver speaker setup menu, or with the sub's volume knob, whichever is easier. Getting the subwoofer volume perfectly dialed-in may take some time. As you watch movies or listen to music, you may feel a need to tweak the sub level up or down to find just the right setting. One of the best indications the sub volume level is optimal is when you aren't aware the sub is working; its bass seems to come from your main speakers.
Turn the sub's volume control half way up. Some auto setup systems will check the wiring, but try to get it right in the first place. When running the auto setup test tones, the room should be as quiet as possible, turn off your air conditioner, and shut all the windows and doors. It's a good idea to leave the room, so you avoid the annoying test tones and so you don't effect the results of the test. Setup systems that equalize the speakers' frequency response, such as Audyssey, may need to be turned on or activated after running the auto setup, check the owner's manual.
Don't assume the EQ-ed sound is better, listen to a few movies and CDs and see if you prefer the equalized sound. EQ systems frequently boost the subwoofer volume too much, so if you think the sub's too loud or low, feel free to either adjust the volume on the subwoofer itself, or via the receiver's manual setup menu. If you're happy with the sound, you're done, if not, go ahead and recheck the settings in the manual speaker setup menus. While you're there confirm the speaker-to-listener distances are in the ballpark.
Most systems are pretty good overall, but the sub-to-listener distance might be way out of whack. I've seen them mistake a foot distance for 42 feet!

Then again, if you're at all technically inclined you might want to forgo the auto setup and tackle manual speaker setup. It's not very difficult, but you should use a sound pressure level meter, such as a Radio Shack You can probably do a better job than the auto setup. Be respectful, keep it civil and stay on topic.
