Duct tape is very universal!

Zip ties would probably work too.

You shouldn't need a adapter bracket for the UMM-6 or UMIK mic on the boom stand. But you will need the adapter for the Audessy mic. Or duct tape or something. But the camera adapter bracket for the Audessy mic is cheap.

I just ordered up the stand and the adapter. Thanks for the help!

On another note, does anyone have a side by side photo of a xs15se and a xv15se? I am curious of the size difference when they are next to each other vs just reading the measurements and doing measurements in the air with a tape measure.

They are pretty different subs and I doubt any single person is likely to have both. Your best bet might be to do cardboard cutouts of the dimensions and place them side by side.

That would be waaay to easy!

On another note, there is no way I would be able to get by with a bigger sub that my XS15SE anyways. The wife wasn't too thrilled with this, let alone something noticeably bigger.

Yes, however that chart is composed of mixing and matching data sets. Not saying it is 100% incorrect but I would use data-bass.com numbers for better accuracy.

Proud Owner of 2 XS15se's - Help with Integration!

Hi everyone -

I'm a proud owner of Dual XS15se's. Tom and PSA did a fantastic job rushing out my subs before Christmas and I've spent countless hours sense setting everything up!

I chose to order 2 XS15se's to smooth out frequency response throughout the listening area (and to eliminate the ability to locate the subs).

I have a 6000 cubic foot room, oddly shaped, includes dining room and kitchen. Subs are 8 feet and 15 feet away (non symettrical). One is next to the corner, other is next to a wall.

Using Aud XT32 with their dual sub calibration, my REW curve is below.

I was hoping to get some feedback on the response, any thoughts would be helpful. Let me know if I should consider EQ or anything else? Or, if the curve is great, I can finally just relax! FYI, can't do bass traps as I barely survived the wrath of integrating 2 subs into my living area .

Thanks!

you could defintly benefit from some EQ. your respoinse looks good in the fact that you would need freqeuncey cutting not boosting....using 75db as a baseline ....it could drop down from 25 and 50 and from 50 to 70 and it would be very flat

either way congrats!! glad you are enjoying them!!

This is after XT32??

I would say you still have some work to do regarding placement.

Where is your crossover set? If it's at 70hz it looks like you could benefit from the sub distance tweak.

Are the subs properly gain-matched?

Is this graph un-smoothed?

BTW, you don't have to create a screenshot...see that camera icon in the upper left corner of the REW interface? Click that to create a grab of your graphs.

I agree placement is the first defense if that is even an option. But if they are on the only possible location grab a minidsp (psa sells them on their site for just over 100$) and will Eq both subs. In fact REW cab create the filters and send them directly to the minidsp and you can see the changes in real time. Nice tool!

Agreed! Other then the dip at 70hz that is not that bad of a response...heck I could probably live with it once the 70hz is fixed. If you want to really tweak you can do as Brian suggested and cut a few areas to flatten it out more.

Don't be afraid to make a gain adjustment on one of the subs to see what kind of effect it has on your FR. It helped eliminate a null in my FR before I applied eq.

To answer your question - yes, just a few inches can make a big difference in FR, depends on your room/sub placement/MLP location. With dual XS30s though, with proper sub placement you should be able to create a fairly large "sweet zone". The above tells me that you do not have your subs in their optimum positions for your room. Either that, or your room really, really sucks for bass and you need more than 2 subs to smooth the response.

Or, you're still using a pillow for your Audyssey/REW mics.
Alan, so my mic boom came in and pretty much no change. I will do some of the other things you suggested, but I don't understand the input output screen you showed me in the REW setup. What should I have the ASIO output set to. Right now it's HDMI 1 and I have the choice of up to 8.


First graph is without mic boom second graph with. Second graph is subs and mains only dark line is with XT32 lighter without.

^^ HDMI1 is left speaker, 2 is right speaker, 3 is center, 4 is sub. So if those graphs are with hdmi1, then you measured your left speaker plus subs if the subs were on which seem they are. Your 70hz dip can be resolved/reduced by adjusting subs distance from your x4000. What are the sub1 and 2 distances set by Audessey, what is your crossover?

The subs are 15.5 and 14.9. My mains are crossed at 250 the CC at 40. Subs are LFE +Main. I changed them both to 80, see results in graph below. I know I need to run the audessey sub distance tweak. Will have to do it tomorrow. I had been running it before changing both distances at the same time. Tomorrow will do it one at a time.

^^ try subs as LFE only. LFE+main could cause cancellation. Are the graph measured with hdmi1? If so, you measured ONLY left speakers and subs, no center was measured. I don't understand what you meant by 250, 40 and 80, 80 on graph. For distance tweak, use either hdmi3 (center) or hdmi1 AND hdmi2 (Both left and right). Try to reduce sub distances to 13 and 12.4 and measure/post graph.

I couldn't figure out how to change decimal points so I moved it by feet. I changed it to 13.5 and 12.9 and out of curiosity I changed it to 11.5 and left it 12.9. I never changed them individually before. Look at the jump.


It's getting to late to play tonight, but let me see if I have my sequence right for tomorrow.
1. Recalibrate with XT32
2. Check levels with hand held SPL
3. Run Sub Distance tweak with XT32 on? or Off?


Thanks,

^^ your last graph has 20db vertical scale. You can change distance to decimal point by going to your avr distance menu, at the very top, change it to 0.1ft then go down to sub 1 and 2 to change them by 0.1ft. Always measure with Audessey ON for subs distance tweak. Try to measure with hdmi3 output and have your center xovered at 80hz. I edited my post above while you replied with yours

Please set your graphs so they sre in 5db increments. Right now you have then in 20db so they are looking more flat then they really are.

But yes it looks like your subs are ridiculously hot. I still think something is wrong with your measurement process. The graphs just don't look right.

Seem way too hot or there is something wrong as your subs are more than 20db higher than your left speaker (if hdmi1 was used for that graph). You should try the subs gain match technique if you have not.

Looks like the little you changed the subs distanced made a huge difference in the yellow graph. You eliminated a 25db null at 80hz.

Where do I change that at?


I am running my subs hot, I have the gain way up because I liked the chest impact. However, the next XT32 run I will use the sub calibration again.

^^ set your limit in REW to bottom=50, top=115. When running subs hot, up them in the avr sub trims and NEVER the subs gain knobs after Auddesey calibration.
