I dunno if I like it. It doesn't seem to play nice with the 45b's. Either that or I just have some setting messed up. I can't really do the sub crawl, because I only have one place to put the thing.

 

I noticed in the Yamaha thread you have the phase set to 180. Should probably be at 0 unless you have the sub at a different distance than your speakers. A pic or diagram of room layout would be nice.

Crossover is at 80. To me, it still seems like the 45's are gobbling up a good portion of the bass notes, even though they are set to "Small". I don't have enough bass really. The test tone for the sub is barely audible. Is that normal?

YPAO. It set the sub at 0.0db, and my left speaker at 0.0. For some reason, it set the right at -0.5.

I'll give that a try. I noticed a bit more bass with it at 180. I'll try and get a pic tonight.

Speaker levels sound OK to me. Setting the phase at 180 may effectively eliminate your bass if the room is not set up properly. If your sub is on the same side of the room as your speakers, the phase will most likely be 0 degrees. 180 is when you have the sub a pretty good distance from the mains, this helps the sound to meet you at the same time in the middle of the room.

It takes about 17.7 ms for sound to travel 25 feet in your room. Not a big deal if your room is small and your subs are close to your mains. Especially seeing how the mind cannot differentiate visual and auditory delays of 10 - 20 ms or so. This becomes a problem when the sound wave (from the sub) is rising in amplitude and meets the same sound wave (from the L/R mains) as it is decreasing in amplitude (or increase in the opposite direction) at the same rate. This effectively cancels the signal. If this happens where you are sitting, you hear nothing. Just think of noise cancelling headphones. Same concept.

Bottom line. If your speakers are the same distance as your subs (from your listening position) then you should hear both at the same time. Essentially complementing each other (additive). If you set your crossovers at the same level for both the mains and the sub (80 Hz) you shouldn't notice any cancellation at all.

Even though this is a visualization of a stage setup, it is still a good point of reference what happens to the sound field in rooms

When I've got my subs up and running, I have them set to 120 in the AVR on LFE. My mains and center are set to 40, wides at 40 and surrounds vary from 60 to 70. The blend of sound is seamless.

What do you mean by 120?

climber07, thanks for your post. A visual representation helps! My sub is basically even with my right front. It's probably a foot and a half behind it.

climber07, thanks for your post. A visual representation helps! My sub is basically even with my right front. It's probably a foot and a half behind it.

I'm fairly certain he is referring to the LPF for LFE setting (Low Pass Filter for Low Frequency Effects). This should always be set to 120hz as far as I know. The LFE channel is the .1 channel (dedicated sub woofer channel) in a 5.1 (or 7.1) surround mix. The sound mixer can put content in the .1 channel that has frequencies up to 120hz. By changing/lowering this setting you can potentially loose out on content that has frequencies above what ever cut off you have selected.

Careful not to confuse this setting with the crossover feature in the AVR. The crossover setting redirects low frequencies that are not mixed in the dedicated sub woofer channel (.1 channel) to the sub.

I'll give that a try. I noticed a bit more bass with it at 180. I'll try and get a pic tonight.

My two cents, for what it's worth:

Leave the sub phase at zero and let YPAO take care of it. It may set your sub distance farther away than it actually is. Leave it where it sets it--it is correcting for signal processing delays within the sub. Everything should be in phase if YPAO is working properly. If you set your phase to 180 before running YPAO, it will just set the distance to correct for it (if possible). If you adjust it from zero to 180 after running YPAO, you are destroying the phase correction YPAO has done. It may sound louder near the crossover point if it is extending bass notes from the mains and sub, but this is not accurate sound reproduction (pure speculation on my part here).

It may set one speaker a bit lower or higher than another because it is farther away or because there is some room correction required. I would leave that as well.

To me and many others, YPAO sets the sub very low. The test signal sounds low for me, too. What I did is turn the sub up to a point where YPAO set it to -4 or -5 dB, then I turned it up (in the AVR) to +1 to +2 dB. This may be more boost than you require, but some tinkering should get you where you want to be. Basically, my aim was to have the sub level where I wanted it with the AVR set not too far from zero.

I'm guessing YPAO is going for a truly flat response, and most of us are used to a more thumping bass. Even at that, though, I agree that the YPAO setting is strikingly low.

Bravo!

The perfect height of the mids/tweeter was the first thing that I noticed when I set the second pair of A9's as surround speakers in relation to my couch. Glad to hear it was the same thing for you.

I guess you decided to remove the jumpers from the A9's to only use the mids/tweeter due to the X-over you did set for these speakers as surround. Right? In my case and due to my room (I have a table to the side of the room that I use for work), I left the jumpers on and time to time (while I'm working at that table), I listen music with the multi-channel option at the receiver and with Audyssey DSX............wink.gif

So, where are the pics Mr. G?

Anytime, set your sub to 0 degrees on the phase. That should do the trick.

I'm going to test it some today using those settings.

I suspect thats really what my problem is, I was thinking I would get thumping bass, but in reality that really isn't what I think you want. The sub should be ancillary, not steal the show. For now, it seems to be doing a decent job, but I'll test it with your settings and see how it goes.

wow,2x Rti8, 4x RTi6, 1 Csi5 - very happy with my sound thank you 15.gif
post #19093 of 34986
The only thing ypao is good for is setting the distance settings...after that use the manual adjustments to get the sound to your liking. I set my subs so Ypao trims -10, then I manually adjust the trim level beteen -5 & -3. Its been mentioned before to not add positive gain in the avr as it can clip the signal causing a loss of headroom.

Yep, yanked those jumpers right out. My FXiA6's are to the sides of my seats doing surround being fed by my XPA-3 (and center). Of course my XPA-2 feeds the mains and now my AVR feeds the "Rear" surrounds. The 2nd set of 9's sit 2' behind the seats and just to the inside of the surrounds.

The Onk 807 is pushing 135w through the upper cabinet of the A9's an man do they sound sweet.

Pics my friend, pics. I know I'm due to post some, nobody has seen my new digs since I moved in last Dec. I'm just a tad bit embarrassed since my subs are on TDY, but, I've got a pair of amped A9's so you know I'm getting bass smile.gif

I will try to get something posted soon.

Happy fathers day to all and especially our newest father. Congrats Enders on your first Fathers Day!

I was going to get some JBL in-wall/ceiling speakers until I saw an amazing deal on the Polk RC80i that I couldn't pass up. I bought the Polk RC85i for the in-wall on my 7.2 system. I was scared to death that they would sound tinny or metally. When I got them installed, I put on Pandora and I switched my receiver to multi channel and I was amazed at how good they sounded. I put on a SACD and the separation and clarity was amazing. I put on a few movies including Flight Of The Phoenix plane crash and was stunned at how much better my system sounded than my old home. I am now a Polk fan and I am going to sell my JBL's and pick up some 75T's with a matching center.

Sojodave, I just installed 7 Polk in-walls (fronts and center driven by an XPA-3) along with an incredible sub and it sounds amazing. Photos in link in my sig line below.

My fellow Polk Audio enthuisiasts as many of you know I am in the market for a new TV. Yesterday I went out to demo a few sets. Based on what I saw in the store I must in good conscience warn anyone who may be considering a new samsung television. Samsung has personally offended me by putting out n the market the most fabulous TV i have ever seen but they have priced above my budget and the Max size is too small. So for anyone out there considering the f8500 plasma be warned do not look at it ever unless you plan on buying it. Just an innocent simple glance will ruin on other sets from consideration....curse you samsung!!

For what its worth I a leaning toward the Sony 70 inch set. It fits my budget and looks good at least in store anyway.

For the price of 1 Samsung, you could buy 2 70 inch Vizios. The F8500 is a nice set - not too crazy about the base on that unit, but the picture quality is excellent.

Why 2 70 inch Vizio's hold on a month or so and get an 80 inch Vizio, and still have enough left for a Hi Def week in Vegas

Being the cheap guy I am I got one of these: http://seattle.craigslist.org/see/eld/3852004268.html about 5 months ago. I still have my 50" Panny 3D in the bedroom. The Panny has better PQ but I sure like the extra screen size and the PQ is pretty good.  You roll the dice on the one I got since you only have two weeks to return it. That's why it's so darn cheap. So far so good. These sets are Costco returns. That F8500 looks sweet for sure.

I know right? I'm ruined on pq. My PN64D8000 had a killer picture, the 8500 is improved on what I didn't think was possible. But I will wait and do what I did when I purchased my 8000, walk in with cash, and for 100 below cost, say, "I'll take that one and this is what I want to pay". Sure, it was the floor model, but I got the full warranty with it.

Many TVs will look good at the store or vise versa. Once you take the TV home and calibrate them you will either keep it or return it.

Samys have won me over for picture quality. I have not been too impressed with their MTBF rate for CCAs (power and controller boards) so make sure you get an extended warranty.

I've had my Samsung for a few years now and I didn't realize how much better it was until my parents watched a movie the other night with us. They said, "Oh my gosh, the picture is so real looking it's freaky. It's like your looking at the real actors on the other side of the TV". That's a review you can't buy... biggrin.gif

Guys, need your advice. I have a pair of RtiA9's and I am wanting to buy an Emotiva external amp to power them and was wondering if I would be better off purchasing the XPA-3 or the XPA-2. I know the XPA-2 produces 300w a channel and the 3 only 200w, but I would also be able to power my center channel leaving my Onkyo 818 to power the heights and rears. Would you go ahead and purchase the XPA-2 and let the 818 take care of the center as well. Just curious as to what you guys would do. I have read that the A9's sound much better with 300w pushing them than 200w. Just wondering if anyone here as any experience with what I am talking about. Thanks guys!!!

Are you going to listen to them loud? If not, get the XPA-3 and use the center channel. If you like music more than movies, and love the feeling of hard smooth bass, get the XPA-2. You will rarely, if ever, use more than 150W - 200W for movies unless your room is extraordinarily large. I hardly ever see more than two LEDs on the meter on my XPA-2 watching movies. For music... let's just say most of the LEDs are getting a workout. As well as the neighborhoods ears.

My vote is on the XPA-2 and then let your receiver taking care of all other speakers. Once you start hearing the difference on driving your A9's with the XPA-2, then you will quickly switch to listening more music than before (at least that happened to me) and then you will really appreciate/enjoy to have the XPA-2 and A9's combo at your home. Of course, for movies you will be rocking a pretty cool system by adding all the other speakers driven by the 818.

My two cents!

Very yes. I think the three of us had the same progression, going from the XPA-3 (or 5) and then to the XPA-2. And then music started to become a lot more popular.

Simply put chrisu, if you love music, definitely go for the XPA-2. The A9's are built like tanks, can take tons of power, the louder they go, the better they sound. You will not be able to get enough of the A9 + power goodness.
