Thanks for the input so far!

I don't really want to be running 6db hot...but that's what it took to get the sub to even sound like its there. It's not like it's shaking things on the wall...

Which leads me to believe maybe it's a setup issue. I'd consider myself tho be an average listener...so if most are only going 1db - 3db above, maybe i should look at some other reasons the sub is sounding somewhat weak...

Did you just put your sub in any location? Are did u do the infamous sub crawl to find the most suitable location?

After going through this post (as well as others) and speaking with Tom, I am ordering an XS30 here soon. I have been away from home theater/audio for awhile, but decided to get back into it...Merry Christmas to me! smile.gif

Congrats on your gift. I wanted to go with a XV30 or XS30, but if I would of done that, I wouldn't of been able to upgrade my other speakers. I'm still waiting for a tracking # for my XV15. I've been listening to my Arx 3.0 speakers for the time being, and they do okay with bass, but not as good as the XV15 will do!cool.gif

Yeah, finally. I was very unhappy with my previous 7.2 set up. Music wise it just didn't sound like I was hoping. The Arx are just in another level for music and movies as well. At the moment, I'm talking to a few guys who are selling some Arx speakers, but they are taking forever to respond back. According to them they want to sell them, and I am frankly getting a little bit annoyed at them not answering my questions in a timely manner. I might just end up buying a new Pair of Arx towers to at least have a 5.1 set up.

Do you have REW? I ask because after calibration I had to bump what audyssey put for my duals up about 5db. This was not 5 DB hot according to REW. This bump made the level finally flat. Otherwise my mains were too hot for the sub. So I think your best bet here is to get measuring equipment to see where you stand. Who knows what you "like" might actually be the right thing

Brain,

Sorry for bothering. I just started reading about REW and measuring equipment, but to be honest I really don't know what to buy. Is there anything that you recommend buying that works well, and it won't cost too much?

No bother. The cross-spectrum.com calibrated umik for umm6 USB mic. They are both plug and play. Also you need to download the free REW software. Make sure you read the users guide. It's very well laid out. And make it very easy to take measurements. Feel free to ask me. I will help as best I can.

Won't you still need an external sound card to store any data or REW measurements.... taken?

I was also recommended something like Behringer EMC8000 or similar along with a decent external SC + REW would do the trick. I'm just curious to read what some of you guys use along with your receivers REQ.

Thanks, Bill

No you don't need an external sound card. If your computer has a headphone out jack, its sound card is sufficient to run REW

Once figured out, it's pretty much plug-n-play. Everything happens on the computer with connective cords to transfer the signal to the AVR that transfers the signal to the subs and a cable to connect the measuring microphone to the computer to calculate the graph and save created data.

Unlike Behringer ECM8000 and Dayton EMM-6 microphones, the Dayton UMM-6 have a USB output so they can be used with PC's and Mac's without need of an external phantom power or USB/Firewire interface. The UMM-6 appears as an audio input device available for use in many audio measurement software programs. The stock units come with on-axis calibration curves.

Load up War Of The Worlds emergence scene at -10db master volume with your XV15 set to what Audyssey set during calibration, and you will now feel and hear your sub. It's not meant to stick out like a sore thumb.

I've been struggling for weeks to integrate my 4 XS15s into my living room (see this thread). I've had better luck recently and ended up here - green is Audyssey off, blue is Audyssey on:



Sounds really really good with both movies and music, but when I push the volume I'm running out of headroom. The subs are only running 3db hot from where Audyssey set them. If I turn them down 3db, I'm good to about -5db MV. With them at 0db (3db hot), I start to hit the soft limiter at around -10db MV.

Seems to me I should be getting more output than I am....am I doing something wrong?

From your graph, in my opinion, with Audyssey turned on, your center channel needs to be turned up two or three dB and your subs need to be turned down two or three dB.

Those graphs are with subs + FL/R only - no center channel. smile.gif

If you look at a full range graph - on average, my subs are only 3db hot from the mains....could it be my large space (4800^3 feet) causing me to run out of headroom? I thought quad XS15s would be enough....maybe not.

Anyways, even if I turn the subs down 3db and make them even with the mains, I'm still only getting to -5 MV before the limiter kicks in.............

what movies make the limiter kick in? On WOTW it makes my Triax distort at -5, not to happy about it.

Are you running your sub hot? If yes, by how much?

That's weird because I've tried my Triax maxed out on the gain many times on every demo clip above reference and it never gave in or distorted. Now I have it less hot for normal use but when I first got it I swear I couldn't get it to clip or distort. There's gotta be something else in the equation that would mess with the sub.

On my video clips of the movie demo "the pulse" and the bass test, the Triax is maxed out on the back and volume is +6 above reference and you can see it didn't phase the Triax.
