Or try using the line input and see if that helps.

Here is a sweep with my dual Triax's. I am very happy, especially since I spent zero time trying to place them. Just put them behind the couch.

Word is 1/6 smoothing is what we hear....however I like to use 1/12 smoothing as it does not mask and dips but makes the response more easily readable, especially above 150hz.

I like the bass in Toy Story 3 as well and the 3D effect looked good to me as well. The first Toy Story is still my favorite though with some pretty good bass scenes even though they are short.

Yea there seems to be some different opinions on this topic. Rew thread recomends no smoothing, but Bill F says 1/6 smoothing is fine, Mark Seaton says 1/12 smoothing is ok. So somewhere between no smoothing and 1/6 smoothing should be used I guess lol.

to be honest...over a the REW thread they are graph nazi's. they get very bent out of shape if everything isn't EXACTLY like the guide lol. my graph's are +/- <3db and according to Tom V. are fantastic...but to the REW thread they leave a lot to be desired and something must be wrong...they are helpful though if you do things correct

If it helps, in my opinion, the deeper one goes into these types of rabbit holes, the more myopic becomes the view.

this is true...but I hate when I think i have it dialed in (to my ears it IS dialed in and the graph is there to back it up) then i feel the need to re-do everything because its almost peer pressure to change it haha

That's why it's called "peer pressure." biggrin.gif

I've come to the conclusion that there's nothing wrong with keeping up with the Jones'. In American society, it's become a slam on anybody who tries to keep up with the Jones'. But what's wrong with keeping up with the Jones'? If keeping up with the Jones' makes one a better person, within fiscal and reasonable effort, go for it.

(why that guy always has such a nice yard, his car is always polished and his sound system is to die for. Smart, handsome, charismatic, wealthy.....why i'll show him. I'll let my yard turn to weeds, let the weather ruin the paint on my car and get an ugly wife. And should he ever come over to listen to my subwoofer system, that'll be the last time he does that as my system will sound so terrible he'll want to stick knitting needles in his ears.)

Mediocrity is it's own form of punishment.

(i'm a slacker and intentionally, an underperformer but if you looked in on our life, you'd never know it)

When the weather changes from outdoor weather to indoor weather, I'll completely do our subwoofer sound system, all over again. It's a hobby. It's entertainment. It's about the journey, not the destination.

(i hope the above makes sense)

yes it does....and i agree or i would never have bought the calibration mic and figured out how to use REW...just gets tedious at times (i guess because i only have small windows to ether calibrate or watch movies close to reference and I hate "wasting" it calibrating hahah)

It reads like the Jones' are getting to you.

My next door neighbor is a Jones'. I don't speak to him as there's no point. He knows everything and I know nothing but he does keep his car and yard in good shape and that motivates me to do the same. So, being next to a Jones ain't the worst thing that could happen to me.

A hobby is fun and entertaining. No reason to make it into a job. I'm retired. Why would I want to get a second career? If the rest of the world wants to work 24/7, I'm happy for them.

My wife taught me that it's not about reference. We listen at -20 to -30 MCV. The sound level meter reads our sound level at 65dB to 96dB. The sound is engaging and a part of the movie but the subwoofers are not the whole movie. Not having even close to the best subwoofer system, if I wanted, the MCV could be cranked up to full reference and I would measure in the >108dB range. The point, coming to these forums, one tends to make their subwoofer system front and center as opposed to being in the background (a part of the visual) where the sound engineer and producer intended them to be.

(we will be upgrading the subwoofer system and AVR for more headroom)

During yesterday's 49'er game (we're 49'er fans), due to Dolby Digital surround, we had fans behind us cheering on the 49'ers. It was great as it made us feel like we were in the stadium but with much better seats. In my opinion, it's about the experience, not the subwoofers.

(yes, the subs are turned on during football games)

Please, don't let the Jones' get to you as that's guaranteed to take the fun out of the hobby.

Hey Guys, until I can get things squared away with my setup, would placing the Triax along one of the side walls about 1/3rd to 1/2 away from the front wall be really dumb and a waste of time. I 'm getting ready to download REW and order the UMIK, might be another dumb move since it will take me forever to learn to use it. I have the Galaxy CM-140 SPL, I really don't like the digital readout, it seems like it's all over the place. It's the Verikfied + model, Herb said to use the meter with the ramdom-incidence correction curve, I'm assuming that means if you're using some type of correction software? I seem to getting better results so far with my olt analog Rat Shack meter.
Cheers Jeff

if you read the guide for REW its not that bad.....but getting the mic and output to work properly can somtimes be tedious (especially with a MACbook pro as i use)

if you have any questions about it feel free to ask

Well, I just recently moved my two XS30s along the back wall behind my MLP. They are separated by about 3.5ft. But I heard something I haven't heard before from them. After I setup Aud each sub gain is right around 1230 and the trim was put at -4.5 on AVR and sub distance is 7.5ft(which I think might be a little off). Any how I was playing a scene from OHF(Olympus Has Fallen) last night with the monument falling. I was playing around -18 on MVL and I kept hearing the subs bottoming out pretty sure, it just didn't sound right and I don't ever recall hearing that before when I've played that scene in the past. Was like a "pop" in couple certain parts in that scene. Never have I heard them do that before and don't recall that scene having done that before. So, I rolled off the volume to around -25 it didn't do it then -22 it didn't do it and when I did -20 I could notice it as whichever freq it was was now causing it. I wasn't running anything hot and no extra bass settings were added on my Onk as I double checked that to. I tried 1 sub at a time and the same result was there. I was wondering if maybe it was a bad setup of Aud when I did the 8 positions few days ago. I really just don't recall that scene having a "pop" few times in the LFE before. It just didn't sound right and I noticed it right away. Anyone else who has watched this scene maybe knows. I haven't reran Aud yet to see if it was a issue with the initial setup yet. Thanks

I have that movie, but have not watched it yet. If you'll PM me with the time index of that scene, I'll check it out and let you know if I hear anything weird.

I should mention that I don't have PSA subs, but Rythmiks. I do also have an Empire which I think is similar to the XS30 (dual 15")

I remember there is a scene in the movie Inception that always sounds to me like the subs are straining. It is the scene where Leo is sitting in the chair and is pushed backward in to the bathtub.

Jeff, I can probably help you with REW if you have any problems since I am local. With the UMIK-1 and an external sound card it was pretty easy. My built in sound card could not pass a signal through to my receiver below 40hz for some reason. The external sound card was about $30 and works great.

I gave up using REW on my MAC, had lots of issues where it would try to use the internal mic instead of the UMIK-1 even though it was set as the default mic in the Mac preferences and in REW. No such issues on my Windows laptop.

Here is the newest graph after some minor placement tweaking


3 - JTR 228's LCR (game room)
2 - DIY Sound Group V-8 Coaxials (game room)
4 - PSA Triax's (game room)

you dont need to worry about a sound card if you use a hdmi connection from the pc to avr wink.gif

Audyssey could be boosting the lower octaves trying to achieve a flat response which could be eating up your head room. Boosting frequncies below 30hz 3db effectively cuts the amplifier power in half. Basically if you boost 20hz 3db then you lost 3db of headroom above 20hz. This is a prime example why its important to measure your setup and detrmine the best location for your subs. The less audyssey or any eq system has to correct ther better.

Wouldn't PSA's DSP prevent bottoming out even if Audyssey was trying to cause it?
