For less then $200 more dollars(umik-1 and miniDSP), you could be kicking back listening to this:

Hi Kini62?

Sorry if my post wasn't clear. Quite often I feel like I have 30 minutes to make a big mega post on a topic and the next thing I know I have a few chats, the phone is ringing, and someone is knocking on our door to deliver inbound inventory. So that mega post just turned into the best I can do in 90 seconds..

Anyway, please feel free to let me know if I can answer anything specific?

Exactly my point, Alan and Bear. He might not need the minidsp since he has a XT32 subeqHT avr.

Who are you talking about tvuong? I wasn't aware someone was considering a MiniDSP....I thought we were talking about Fatty getting REW up and running vs. staying ignorant.

Ah, but.....even with subeqHt, you can still put in a sexy house curve with the miniDSP and not muddy up all the other bass.

OK, now that I've discovered that panel in REW....what is Trace Arithmetic and how can I use it?? Does it just average 2 responses or what?

Not for the xs30se or any dual/tri opposed driver cabinet geometry. The design essentially eliminates vibrations through the top and bottom of the cabinet thus negating the need to decouple the cabinet from the floor like the GRAMMA is designed for. You can find some YouTube videos demonstrating how effective the design is with someone placing a glass of water on top of one of these designs (I think someone even posted this on PSA's website reviews of the Triax) and seeing the water not moving.

I use a GRAMMA type of device for my standard front firing subs and they work quite well but the key was my sub-floor. My room is upstairs and the sub-floor is suspended so my particular subs were not doing so well until I put in the GRAMMA type of device. I wouldn't see the need for it if I was downstairs sitting on concrete. This is really one of the reasons why I am so interested in the Triax.

That was direct to Bear's post recommending a minidsp for JT.

Hey guys, a little tip I'm using since I'm always moving my subs around because I'm so anal about everything, I used a piece of masking tape right neat the amp gain knob since I gain match my subs and then put them back into their spots, I mark right where the dial is supposed to be in case I move the gain knob while sliding my subs around, not a big deal to most but for me who gain matches their subs it really helps so I don't have to pull them back out into the room and use masking tape and get the galaxy 140 out and do it all over again. Good job Hop with REW, at least you're trying......THUMBS UP

Thank You #Alan P,#bear123 ,#Brian Fineberg,#McLuvin

I was thinking the same thing.. that the gramma isloation riser might not help do anything to the awesome PSA sub line..

yes I saw the xs30se youtube vid i think it is in the review vid where a glass of water is on top and it does not vibrate at all .. awesome made cabinet...

Thank Tom.. though I still need to calibrate my dual xs30se .. I am enjoying what they are calibrated to at this moment in a basic mode... I am sure I will be posting questions to you guys soon.. when funds are available and I will get the umic mic and do some rew...

The cabinet is not what keeps the XS30se vibration free...it's the dual opposed drivers that cancel out the internal resonances effectively eliminating vibrations.

Jeff,

can you let em know how to gain match the subs? I think it would be benficial for me and tactile feel for the neafield sub

thanks!

Google is your friend...plenty of youtube videos & forum thread tutorials on setting REW and mini dsp's out there on teh interwebz.

If you use HDMI connection between laptop and AVR then Skip past the sound card calibration.

It does, but there is a section on there describing how to change it back.

Only if you are using SubEQ HT. If so, all you would do is set both subs to the same trim setting in the AVR post-Audyssey. After that, raise and lower them by the same amount to get to where you want to be.


EDIT: See Craig's post here.

Brian,
After having both of the gain dials from your subs in the same spot, run Auddesey. The first part of Audessey run is to level match your subs with that on-screen meter by asking you to increase or decrease gain on sub to achieve 75db. Don't do anything there (keep them gain match)and proceed to the rest of Auddesey cal. Audessey more likely set your subs trims 0.5 to 2.5db difference (depend on the distance of each sub to MLP). You would need to set them both to the average of the two and then increase them both more if you run them hot.

Okay after spending many hours moving the subs around the limited locations I can place them at and running Audyssey more times than I can count I have discovered that my room is tough on bass. But I do have a a graph of one of the better locations and wanted to get some thoughts from you guys.

The blue line is the center channel, the red is the left channel and the green is the right channel. I ran it with PLII Cinema since that is how I watch movies and play games. Dynamic EQ is off.

On another note I am questioning Audyssey since I was messing around with phases and ran Audyssey every time I changed it. Then when I was done playing around I put the phase back to where I had it originally when I had my best graph and reran Audyssey and then took measurements again and the graphs were completely different. Nothing was different except the Audyssey settings, the sub never changed locations. That was very frustrating.

Anyway, how do these measurements look over all? If I screwed something up again let me know and I will play some more tomorrow.

I will say I ran that launch scene from Enders Game with the subs where they are for this graph and it sounded the best I have ever heard it.

Still roll off too soon with a 52hz null. Your subs were on this time right? I would measure just the subs with Aud on and off

Did you rerun Audessey after putting the phase back?

With your graph, you are loosing quite a bit of the low end. You can enjoy the subs ALOT more getting them extended down much lower.

I was interested in doing the same thing as well. Tom told me that it would probably be money better spent to hang on to the XV15 (I have the none se version) and to purchase another one with the "within one year" discount. After careful deliberation that is what I have decided to do... There is no doubt that two XV15se ' s would outperform a single XS30se. It would probably cost you less too (there is a cost to do a trade up).

You need to do the sub distance tweak. You have that huge gap with the center channel

And you are a great candidate for a minidsp. You can bring down that hump and have a very nice response.
