I am considering 2 emotivas airmotiv C1 for left and right on top of the subs and a airmotiv C2 for the center.

I read a while ago don’t remember from who about a sub giving him headache nausea effects as he changed from ported to sealed or vice versa.
Is one design prone to give you such side effects?

Today I found that Y cable and hooked the second up and was in shock at how awesome 2 was. I used a cheap red/white RCA cable, split it down the middle and ran it to both subs, unbelievable.
I LoL'd at the size difference of the Logitech Z680 5.1 system I had rigged up downstairs compared to the size of an XV15. And to think I thought that craptastic Logitech sounded pretty good.

ME:
Glad to hear that your happy with the XV15s, can't wait to get the second, I'm going to have a hard time sneaking that second beast into the house without the SO noticing, I'll just tell her again to expect something big today and she will be too excited to notice
I had to post this from November 2012 as I was reading through some of the beginning posts of the PSA sub forum, it's hard to believe it's coming up on six years with PSA, I already had an original XV15 at this time and was waiting on my second when I made this post. This was the last time I had to worry about sneaking any more PSA subs into the house, my missus just gave up and shook her head for the next six years with countless numbers of different PSA subs. I've been telling her the same line all this time, this is the last time honey, I promise, I stopped saying that three years ago, don't have to at our ages now, getting older has it's privileges....................

Most center channels use MTM design (mid-tweeter-mid). While this configuration is good when placed vertically, when placed horizontally, it creates serious issues in off-axis response. A three way horizontal like the airmotiv does work to eliminate the problem to some extent. PSA gets around it by just putting a bookshelf on it's side and swapping the orientation of the horn. The ideal situation is LCR being identical and placed in their natural vertical position. The other solution to the problem is a coaxial design where the tweeter is located in the center of the woofer, however, there are many design limitations to this setup.

Hey Ray... the way I'm doing it is I'm running a 5.2.4 setup with the side surrounds. But I am wired to someday move to the 7.2.4 set up by adding in the rear surrounds. To be honest, last night I was getting incredible surround sound zooming by in the rear of the room without actually having the rear surrounds so I don't know how much difference those rear channels will add. I do know that to add them will cost some money because I will have to buy a different AVR and buy back my original PSA 110's from my dad if he's willing to give them up. But if he is I'll be able to get them at a good price because I sold them to him at a good price.

Thats an S1500? The surrounds look like the 18"s , unless something changed from the 15"s I just had...

Hmm I think I get it now. On the C1 it would only be a issue if is placed vertically?
I thought about that but figure it won’t work vertically so now I figure they should work great horizontally on top of the subs.

Most likely :-) I just remember the effect don’t remember all the details.
So it seem sealed one are just as strong I have such a hard time deciding if ported or sealed after watching a YouTube video.

I know stuff all over the room was shaking but not sure how that translate to tactical feel

Yeah man. I hear ya. The 110sr are so fantastic that I really don’t feel I am missing anything. However I am plan to to add atmos. Already have the wiring and all but will go with on ceiling using prime elevations but will leave the surrounds in back of room. I have then installed wide so they create a really good effect.

Horizontal speakers are a compromise. You'd be better off with the the B1 unless emotiva says that the C1 will work vertically.

Hey PSAers. I'm at the point where I'm about to throw my receiver and sub out the window because i can't figure out what the hell is going on here. If you recall I had an issue where my sub was giving really low output which seemed to have happened after a cord was pulled when the sub and reciever were on. Long story short, the issue sort of resolved itself and things seemed fine...


I was doing some testing a few days ago and everything was working great. I rented Den of Thieves last night (good movie by the way) and was going to do a quick audyssey and the sub was hardly putting out anything. I tried Pandora through my denon and barely any output. I tried REW and I get this response where it tries to take a measurement, but falls off quick at like 50hz. Just seems to run out of gas or something. The real kicker here is that I grabbed my parents Denon last night assuming it was my receiver again...NOPE! The same thing happened. Barely any output.


I tried the test that Tom mentioned, so I grabbed my 3.5mm to RCA cable and plugged it into my 15V. I played "Turn down for what" praying I would get something, and BAM! The floors and walls were shaking with authority. So, both recievers aren't giving a strong signal, and I have no idea why. I've tried multiple cables as well.



Any other things I should try here???? I thought grabbing my friend's sub and trying that with my reciever, but if the sub pounds hard with my phone plugged directly to the sub itself, this doesn't seem to be a sub issue right?


Please help...watching Den of Thieves without the sub just wasn't the same...

So....... last night I was reminded that those of us who hang out on AVS might not think like the rest of the world. I saw my wife carrying one of those narrow sofa tables through the house, I guess she no longer wanted it upstairs. I watched her quizzically as she headed to the basement door. When she opened the door I became concerned. When she had the table half way down the first flight of stairs I realized what she might be up to....

I asked... "Where are you going with that?"
She said... "I'm putting it in the basement behind the couch."
I said.... "You can't do that!"
She asked... "Why not?" (remember she's standing on the stairs holding the table and trying not to ding the walls so she' getting uptight)
I said.... "Because it's going to create new reflection points and I've already run Audyssey and I don't want to do it again."
She said.... "ARE YOU SERIOUS?" (now she's both annoyed AND incredulous and looking at me like I'm an idiot)
I said... "Yes!"

At that point it could have devolved into an argument but I think she's just given up on trying to understand this audio obsession, so she climbed up the stairs saying it was stupid (or I was stupid) or something like that and the problem was averted. I guess most people don't care about stuff like that. Go figure.

was not aware of that, would that be mostly because of a single tweeter?



So would the room compression translate a little to tactical feel or only headache if is to much?

Wow, congrats SF! I'm sure you will post your thoughts once you have it and set up. Extra curious as I currently have just the one in my set up.....

If you recall I had an issue where my sub was giving really low output which seemed to have happened after a cord was pulled when the sub and reciever were on. Long story short, the issue sort of resolved itself and things seemed fine...


I was doing some testing a few days ago and everything was working great. I rented Den of Thieves last night (good movie by the way) and was going to do a quick audyssey and the sub was hardly putting out anything. I tried Pandora through my denon and barely any output. I tried REW and I get this response where it tries to take a measurement, but falls off quick at like 50hz. Just seems to run out of gas or something. The real kicker here is that I grabbed my parents Denon last night assuming it was my receiver again...NOPE! The same thing happened. Barely any output.


I tried the test that Tom mentioned, so I grabbed my 3.5mm to RCA cable and plugged it into my 15V. I played "Turn down for what" praying I would get something, and BAM! The floors and walls were shaking with authority. So, both recievers aren't giving a strong signal, and I have no idea why. I've tried multiple cables as well.



Any other things I should try here???? I thought grabbing my friend's sub and trying that with my reciever, but if the sub pounds hard with my phone plugged directly to the sub itself, this doesn't seem to be a sub issue right?


Please help...watching Den of Thieves without the sub just wasn't the same...
That's a tough one. It could be that both your AVR's are experiencing the same problem (maybe) but that seems unlikely. You said a cord was pulled when they were on? What cord was it?

How you prevent pressure headaches without compromising on tactical feel?

Hi,

I will try to answer the questions in your second paragraph, but it's a complicated subject. The first (and best) answer is don't worry about it. Unless you are prone to headaches from music/movie listening, this is very unlikely to ever be a problem for you.

The second answer is that room compression, and the tactile bass sensations that most people refer to, are different things. Room compression describes a physical phenomenon where someone is feeling substantial pressure against their ear drums (first) and the head and other parts of the body as the experience is sustained. You can feel those sensations as you go about 8' underwater, or as you are in an airplane that pressurizes at mid and high altitudes.

In a home theater, we will mostly feel those sensations at very high volume levels, and even then sturdy home construction and a sealed room may be necessary to feel the sensation of compression very strongly. Other tactile sensations, such as chest punch (which is a mid-bass sensation) or tactile ULF (which is like a deep rumbling sensation) can be felt at SPL's well below those necessary to produce room compression. And, they can be felt in rooms which are open to other spaces.

And, it's not as if that room compression phenomenon exactly sneaks up on us. I have felt that sensation to some extent with movies like Batman Versus Superman, where I was watching at a higher than normal volume level, with a lot of bass boost. I felt my ear drums flutter (quiver) a little and knew to back-off the volume. It wasn't really comfortable anyway, and I never want to damage my hearing.

Chest punch and tactile ULF are sensations I like. Room compression (or airplane compression, for that matter) is not something I personally care for. YMMV! But, if you don't want to experience it, particularly to the extent that you get a headache, it is certainly something you can control. Just back-off the master volume a little. If you would like to learn a little more about the various tactile sensations, and what I believe causes them, Section VII of the Guide in my signature will help to explain them. This is a direct link to that section:

It was a sub cord I think, but I just popped in to chat with Tom and it's resolved. A few nights ago I was playing around with the room size knob, and I think by accident I turned the frequency knob all the way down to 40hz instead of at 150. I wasn't aware this effects things in the receiver, but apparently it does. So problem solved!!


Crazy how back to life one feels once they know their sub is up and running
