Couple questions about Yamaha RX-A3060

[Pogre]

Another way to think of phase is delay. It can be helpful if your mains are not close to the subs. For example if the subs are in the rear of the room. It's also useful for maintaining support in the XO region, but adding/subtracting distance in the avr can do the same thing basically. When I measure my subs, the two in front of the room(recently moved) work best at 0 and the one in the back is best at 180.(it only has 180/0). If I flip the switch on the one in the rear when running the test tone, I can lose around 10db. Phase is critical.

Thank you! I was starting to feel like I was drowning and you just tossed me a life preserver.

Lol! I hope it floats!
Another thing is phase is frequency dependent so if you're setting phase on multiple subs with the avr test tone, just know that it will get you close but probably not perfect. The only real way to know is REW sweeps. Also, on a single sub, you can play a test tone at the XO which will use the mains and subs together. Move the phase and note the spl. The highest number should be best. Also run tones above and below. If xo support is good you shouldn't see any dips. This is only a quick n dirty. REW is really the best way. But sometimes ya do watcha gotta do.

Hey guys
http://www.avsforum.com/forum/90-receivers-amps-processors/1137156-anatomy-audio-video-receiver.html

How would rate this piece? Is it accurate enough?

Decent piece, albeit a bit old but things in general remain the same.

How would you consider this as well?

Look at the thread about best speaker brands here at AH I posted in post # 11, this one not so much (especially # 4 like Pogre said). Best for one guy may not be the best for another; price/value factors (and furniture factors) vary widely too.

Yeah, blose over jbl pro, kef, infinity? That's what's wrong with the internet. Fum duckers...

I'm really getting mixed feeds online about polk... some refer to them as garbage while some declare them pioneers.. when it comes to my speakers mostly i get 4.5 out of 5 rating (mostly amazon)... someone even praised the inferior seiers T and rated 9.5 out of 10.. on the other hand, B&W seems to be the best to me according to my search.. but again there is always somebody out who disagrees completely

Polk was a pioneer of sorts but that was a while ago (l remember a neighbor of mine got a pair of relatively new Polks in the 70s and they were pretty nice). Their higher end speakers are still regarded pretty well.
B&W's top of the line speakers are very well regarded; personally have only heard some of their lower end speakers (685 series I believe) and wasn't impressed.

I mean the theory about impedance and sensitivity being most important clearly missing some factors when choosing a sloudspeaker..

Aside from personal taste in sound, which should be a primary factor in choosing a speaker, impedance and sensitivity are important in determining an amp needed to drive them. If you want to be sure to drive them easily with an avr type amp, then choosing higher impedance and sensitivity can be a good thing to consider to make life easier on the amp and still obtain higher spls.

you lost me completely after REW sweeps
and what do you mean by XO and spl?

again with spl .. but I get most of what you say .. thank you my friend

SPL (sound pressure level, expressed in dB) is an important concept and how amps and speakers work together to achieve the levels you want....

 

[William Lemmerhirt]

Sorry about that. Spl=sound pressure leve. Xo=crossover.

 

[lovinthehd]

XO is crossover (x for us christian descendants and over). REW is a freeware audio analysis software you can use on your laptop with a measurement mic to analyze sound in your room, many of us use it.

ps added link for REW

 

[Pogre]

I don't have the REW software, measurement mic and DSP (digital signal processor) and got my system sounding really good. Somewhere down the road I'll purchase the equipment and dial everything in even better, but I'm not in a rush. A MiniDSP and Umik Mic cost a couple hundred dollars. I need to let my wife cool down some more before I do that.

The phase setting has to do with timing, I believe? Most times zero is the preferred setting. Occasionally there might be a room or if you're using 2 subs setting the phase to 180 can help, but is not usually the case. I have the phase at 0 for both of mine.

The low pass filter prevents your sub from playing higher frequencies, which it wasn't designed to do. If you use the bass management in your avr (lfe out) you should turn the filter knob all the way to the right where it says "set here when using lfe out from receiver".

Using your receiver to do bass management is recommended. Turning the knob all the way to the right will bypass the sub's low pass filter and let your avr set a crossover (high pass and low pass filters) for a smoother transition from your main speakers to your subwoofer. If you do use the bass management (lfe out) on your receiver make sure your speakers are set to "small".

*Edit: It looks like you might want to plug the rca into the right (red) input for lfe on that particular sub if I'm reading it correctly.

I looked around in the settings and the jacks on the back.. there was nothing mentioning lfe out.. just pre out written on the subs output jack... does the bass management happens automatically maybe?

And what happens if i kept the speaker large or big? Because ypao done the setting for me automatically

 

[lovinthehd]

The sub connected to the pre-outs without bass management engaged (telling your avr your speakers are "large" or "full range") will only output LFE content (content with an LFE or .1 soundtrack); when you tell the avr you want to use bass management for your speakers (recommended with a sub in play) then you set your speakers to use a crossover (and/or set those speakers to "small", depends on avr), then the sub will also provide the bass content you're redirecting from the speakers, the avr will apply a low pass filter for the sub and a high pass filter for your speakers (the crossover), which is somewhat magic

So let see if I got this right..
1. Turn the low pass knob all the way to right on the sub
2. Make all my speakers small or only the front ones?
3. When i do that its gonna ask me how many Hz, range from 40-160Hz. What should I choose?

Choose 80hz and use the right input.

 

[Hasan Alnajdi]

Small For all speakers?

Yes
