The length of the cable will have precisely zero effect on anything. Propagation speed is a significant fraction of C.

It's actually the levels that are going to be messed up - the microphone's response curve won't match the one in the receiver's memory.

This. Most likely it won't be able to figure the correct speaker distance due to different cable length and volume may be too quiet/loud but for setting levels and so on it should work. If your amp let's you out your own distance measurements in do that.

I disagree. Speaker distance calculations should be accurate. The delay is the speed of sound from speaker to mic, not the wire length which is the speed of light.

The SPL level matching should also be fine, but possibly not calibrated exactly to reference.

Standing wave calculations and seat to seat variation will probably be good too.

What will be off is the frequency response. However even thought the mics might not be perfect vs a calibrated mic, they might not be off enough for it to matter. My audyssey xt32 mic was close enough that I couldn't tell the see a difference in real world measurements using REW, and was actually better than the pro calibrated mic below 80hz.

The pioneer stuff might be a similar story.

Edit: lol I need sleep. Gotta work 2x as much with these loving oil prices.

I picked up one of these off Gumtree for $100. I was initially running it off one channel as the sub is 4 ohm, but I decided to live on the edge and now it is running off 2 of these channels bridged.

All the crossovers are done in software. It has high pass and delay on the mains, and low pass and high pass on the sub. It drops off below about 25Hz in my room but should be easily fixed with a little EQ. Just need an amp with a bit more headroom first. 150W should be more than enough.

Edit: Thought I'd share a little more about my setup. Here are my custom speaker wires that I artisanally crafted.



The extra conductor picks up stray electrons and diverts them into quantum pocketry, widening the soundstage.

An older iteration of my setup with smaller mains. Note the acoustic doilies.



And the best part, I was given all these old record sleeves by a local vinyl shop in exchange for a Ben Folds Five Whatever and Ever Amen disc. They will end up plastered all over the sub.

"Just" 100 WPC :lol:

On a set of JBLs like that, 100 WPC is more than enough oomph for rock concert SPL in an average-sized room. I bet you hardly ever use more than 10 WPC in normal use.

I hardly use that much to drive my JBL 4410s to neighbor-hating levels. Efficient speakers rule.

I will fight someone to the death over this. I'm a guy who loves his home theater, and I would sooner watch movies on my phone than harm that fireplace in any permanent way. The thing is from the 1800's and built like a rock. I also actually use it.

After I broke up with my wife, found out WAF is more important to me than it ever was to her. I'm not turning my formal living room into a man-cave, damnit.

Also, it looks way worse than it is. You're looking up at maybe a 15 degree angle, and probably slouching way the hell down on the couch anyways.

There's no way in hell that would fit, or be acoustically acceptable. I was thinking about building a small shelf just below the mantle and just accepting that the cord is going to be visible. :suicide:

This is probably the stupidest thing anybody's ever said, but could you split your center channel into two very small speakers that go on either side of the tv? The sweet spot would be tiny but it might not sound bad?

I just had my living room remodeled and that's exactly what I'm planning to do. I've lived in this house for a year and only had a TV in the basement and bedroom. Above the fireplace is the only spot that works in the living room, but I'd rather not loving have a TV than crane my neck to watch. That being said they're like $600. So. Yeah. Anyone have a recommendation on a cheaper pull-down over-the-fireplace TV mount? :D

The TV location aside, what's up with that box next to the fireplace, is that the sub? And the chair is super close. How is that chair functional for anything in the room? Did that location really pass WAF?

Every time I see a room set up like that I ask myself is there not another way to arrange the room so the fireplace can exist without ruining the mantle by having a TV crammed on it?

Also good luck with the cooling on that set... above fireplace + no clearance around the top or bottom of the set

I'm sorry, but this is a really, really unattractive setup. I know that you think you're preserving the "formal living room" and I hugely respect that, but you're actually breaking a ton of design and aesthetics rules, in very bad ways. Your desire to keep the TV over the fireplace is actually making the room give a different impression from "mature, well-thought out living room." It looks pretty bachelor, tbh.

The placement of everything- the TV, the speakers, the chair- looks completely out of whack and awkward on that wall. It simply can't work there and you need to find another place to put them.

If you moved your setup one wall to the left and maybe put your TV on a unit (so now the fireplace is to your right if you're watching TV), and put a tasteful shelf or picture up where the TV is now, your living room would look substantially classier and more grownup.



You could move the chair from next to the fireplace to directly across from it. Or have two chairs there with maybe a small table between them.



Alternatively, you could swap the couch for a big wraparound if you want the best of both worlds of fire and TV time.

Secondly, I already said I like it there. I'm not looking for decorating tips.

Sorry dude. I guess the room itself just plain sucks for this, but I understand the limits.

As for the center channel: I guess put it where it fits? Ideal placement would be either directly above or below the TV, as in-line with the R and L channels as you can possibly get it.

Honestly, I really can't stress how much of a non-issue it is in person. I know the pictures make my living room look small, but the distance from the TV to sitting position on the couch is ~11 ft. It's less than 3 ft vertical from where my head is to the center of the screen, which gives me an angle of ~15 degrees to the screen; barely above neutral sitting position. My couch also just happens to have a recline of ~20 degrees, so if you're lying back with your feet up on an ottoman (which I usually am), it's pretty much dead-center in your vision. I spent a lot of time making sure the ergonomics were right, or I would have gotten one of those mounts that lets you pull the TV down (probably motorized). Back problems run in my family, and my mom is an OT, so that was my first concern. It's also less intrusive than an ugly TV stand, IMO. All of the equipment is tucked away in the basement with wires in the walls, so all you see are the TV and the speakers. I also can't explain how amazing it is to watch one of my favorite movies with a classic wood fire roaring in the fireplace and a glass of scotch in my hand. :feelsgood:

I tried putting the TV in every conceivable location in the room. The only problem I have with the new TV where it is is that the center channel no longer fits. I've pretty much settled on building a shelf for it below the TV, but I want to do the least amount of irreversible modification to the fireplace as possible. I'm trying to decide whether anchoring to the wood or the brick would be better. I'm leaning towards wood because you can just putty the holes, but on the other hand, you can always repoint the brick.

If you are making a shelf, you could attach it to the wall instead of the fireplace. Build it to drop down over the mantle. Seems like going into the brick will be hard and look bad if you take the shelf out, so I wouldn't do that.

I was just thinking that, actually. It would also give me a convenient way to hide the speaker wire.

I'm still undecided if it should go in front of the mantle or below it. Below would be trickier, but might look less out of place.

Well obviously you take it out if you're going to make a fire. It wasn't mounted or anything, just sitting there. You couldn't see it either with the metal curtain thing closed. A really simple solution, I'd recommend it if you don't use the fireplace constantly in the winter.
