Random Tech thread.

So I also got a Denon AVR-S760H receiver for my new TV. The bonus room in the house I bought was pre-wired and had Klipsch speakers mounted to the ceiling. I think they were Klipsch Synergy C1 speakers, that's what Google Lens told me when I took pics and uploaded. That would make sense because those speakers are like 15-20 years old and the house was built in 2010, so the original owner probably installed them.

I hooked up the Denon receiver to the speakers where the wires terminate in the closet. To facilitate the receiver to the TV, I had a tech run a 49 foot fiber optic 8k certified HDMI cable that I got from trusted vendor Monoprice, in the ceiling from the closet (where the receiver is) to the TV (on the front wall in the front of the room, where the left, center and right speakers are also mounted above, on the ceiling). I think I only needed 30 feet but I bought 49 foot anyway.

Yesterday I got around to trying to hook everything up.

I ran the Audyssey calibration tool with the included mic. When I did so, it kept giving me "phase errors." It would say the front left speaker had a phase error. Then I'd run it again and it would tell me the center speaker had a phase error. Then I'd run it again and it would tell me the right speaker and the center speaker had a phase error. Then I'd run it again and it would say the left speaker had a phase error. It was never consistent in which speakers it was telling me had phase errors, but it was never the rear surrounds, just one or multiple of the front 3.

For the moment I decided to "ignore," the reported phase errors and proceed with set up, because I was hearing sound out of the speakers, albeit the left and right sounded much quieter than the center.

I hooked up the Xbox and PS5 with separate 6 foot 8k HDMIs from Amazon (so I trust these much less, but there are 2 of them, and in connecting them directly to the TV they do tell me that they are passing 4k at 120hz as advertised) from the consoles to the receiver.

In starting to run some games and apps, I'm getting problems. I ran a UHD 4k Blu Ray (Saving Private Ryan - Normandy scene) and it sounded great. My ear is untrained but I didn't NOTICE any imbalances or anything that sounded too quiet or wrong.

I then fired up some games, and here is where the problems started. I set the xbox Audio settings to 5.1 uncompressed. When playing Red Dead Redemption, the front end loading screens and menus sounded.... far away? "Tinny"? Like it was coming out of headphones? The sound was very small and flat. Then when I got into the game, I was walking around camp, so there are other characters talking in all directions around me. The sound when your character speaks is very low and muted. If I swivel the camera around, the sound changes, obviously. I sounds better when it's coming through the rear (surround) speakers. The front speakers, something is off. It's not playing loudly enough and sounds like I'm inside a tin can.

I fire up Forza Motorsport. Same thing. I can hear the crowd roar in a race behind me. I can hear the echoes of my engine bouncing off the wall of the track being played behind me over the surrounds. But the main front speakers, I can barely hear the revving of the engine at all. It's like its almost muted. I hear it way better just connecting the Xbox directly to the TV over the same 49 foot HDMI (ie, if I unplug the 49' HDMI from the receiver and plug it directly into the Xbox).

Shredder's revenge (Teenage Mutant Ninja Turtles) - the whole intro song sounds like it's muffled and tinny. Get in game, the character selection screen, I can barely hear the voice over in the menus.

I switch to Playstation 5. Fire up Resogun (a 3D-like Space Invaders kind of game). I hear the sound of my guns coming from the rear surrounds, but again, basically nothing from the fronts. I walk up and listen, I do hear sound, but it is very small, very tinny, like I'm listening from inside a can.

So I run the Audyssey calibration yet again this morning. It tells me center and right are having phase errors. When I click more info it says that the wires may need to be switched (+ and -). I verify by eye-checking that for both the receiver and the speakers, it's black to black and red to red, so I assume it's matched correctly for positive and negative.

Nonetheless, I decide to start monkeying with it. Can't hurt to try to swap the wires. So I get a stepladder and start unscrewing the wires from the right front speaker, on the ceiling.

Dumb idea, Smitty.

The speaker comes loose from the 4 screws mounting it to the ceiling (I'm guessing an amature mount job to begin with) and comes crashing down to the (carpeted) floor, and smashes. The mount at least is toast. The speaker itself, the frame is cracked. I don't know if the speaker is dead or what, but I can't mount it. And I can't run any more tests while HOLDING it by the ceiling so I can connect the wires.

So.

I have two questions.

Does anyone have any idea what the problem MIGHT have been? Crappy speakers that don't work cause they are 15 years old despite being Klipsch? Bad speaker wiring in the ceiling? A faulty receiver? I assume the 49 foot HDMI is NOT the problem because everything seems to work if I plug the 49 foot HDMI directly from console to TB (though its obviously just stereo sound in that case). Settings problem? I had the Xbox set to 5.1 uncompressed when it was giving me trouble. I tried Dolby Digital too and that seemed maybe a little better but still something was wrong and the fronts weren't giving me full sound.

Next question:

I just spent like $1700 on this TV and I don't have $1500 to spend on new speakers, but I was in the market for a bluetooth subwoofer anyway. Does anyone have an affordable 2.1 or 5.1 recommendation? I at least wanted to maybe look to get a 2.1, that will give me the bluetooth subwoofer and then replacement left and right, and I can go from there, but I'd consider the 5.1 and replacing all the speakers at this point if the cost was similar. I don't see many 2.1 options.

Thanks in advance.
 
Whats the outputs on the receiver compared? Kind of impacts the speakers. I've got bored surround in my theater room, it can be awesome.

Not following the question.

The receiver has lots of outputs on the back. Cable/Sat, BluRay, Game, Aux 1, Aux 2, etc.
 
Ok, so an update though. I contacted Denon support. They said since I was reporting good audio coming out of the surrounds, to hook the surrounds up to the front left and right wire inputs on the receiver and leave the actual front left and right speakers disconnected for the moment.

I did that and re-ran set up. Everything was immediately clear. Fired up the xbox, everything sounded good as well (except that the sound was now coming from behind me, because, well, the receiver was sending sound it thought was coming out of the front left and right to the surround speakers behind me).

So I think it's a speaker issue - either the speaker itself or the wiring that's running to the speaker through the ceiling.

And because, as I said in the earlier post, I dropped and busted the right front, I'm in the market for very affordable but not shitty speakers.

I'm thinking a 2.1 package. I need a wireless subwoofer anyway.

Anyone got any recommendations?
 
Those sound like inputs

Sorry, I guess that's what I meant, I mess up the terminology.

It has lots of ports in the back to plug different devices into it. I plug the Xbox into the "game" port. So I guess the direction there is the Xbox is sending the information INTO the receiver, then, so yes, it's an input.

There is only ONE output then. It's the output that is connected with the 49 foot HDMI to the TV.

Sorry, I meant Watts and Ohms on the output of your receiver. It impacts what speakers you want to match with it.
 
edit: Maybe it doesn't? I thought someone told me it supports bluetooth subwoofer. Perhaps not.

Oh well then I'll need a wired subwoofer and a long speaker wire to run through the ceiling.

Oh right, they said I can get a wireless subwoofer kit.

It's 75 watt output per speaker at 8 ohm.

I think with the HEOS you can connect a wireless sub. At least my quick google tells me that.
 
So that should be sufficient for any wall mount speakers I get?

Maybe, I mean don't get speakers that can't handle 75 watts but that's not too difficult. I don't fully understand OHMS but 8 ohm speakers shouldn't be too hard to find.

Where are the speakers mounted at? Like in my situation I got some Atmos Speakers for the back surround because of the high position on the wall near the ceiling.

Go back to post #340 on page 17 and you can see a picture of the front of the room.

It's before I got the 85 inch TV, I'll have to post another pic.
 
Here, have a tour of my bonus room. It’s a work in progress.

Very nice.

So these are the speakers I'm running on mine. I don't have everything ran to a media closet even though technically I could. Please ignore my kids mess.
