Bear or anyone following these directions i'm not finding my umik-1 mic under step 5 or 6....

Mercury - There should have been a pdf guide from where you downloaded the REW software on HTShack. One of the primary reasons why the mic does not show up is because it is being used by another computer resource. That pdf guide does a very good walkthrough and setup checklist. Please follow all the steps in that guide, it should help you.

EDIT:
Look here, there are links to help with the setup.

REW's learning curve is steep. It took me several days to figure out and I'm still not 100% sure it's configured properly. I ran into a few anomalies. My biggest issue was that Windows wouldn't recognize the UMIK (I didn't use a HDMI so the ASIO driver set up doesn't apply) and none of the other guides I found addressed how to work around it. I believe I'm able to take good measurements up to 200 hz, but for some reason the SPL meter is way off for the higher frequencies (confirmed by use of another SPL meter).

Hi bass81,

We have been going back and re-doing the charts like you recommended a while back. Let me know what you think..

Tom,
I have been meaning to email you about the new triple xs30se's. It has been almost two weeks since I set them up and they are now definitely sounding much better than day 1. A simple naive way to explain this would be, a drum was sounding smooth on day 1 and now it is hitting like a hammer- sharp and no reverberations. The older XS30's did not exhibit this behavior even after about 4 weeks and it had a smoother signal decay. My wife is complaining now more than before about the boom boom

The se drivers seem to be of different caliber compared to the previous gen. Also, now I have to dial down by about 3-4 dB on the AVR SW level to achieve similar perceptible bass as day 1. Bottomline, I am thinking if you do the curves after the subs have opened up, you may get more output and probably a different frequency response characteristic. I haven't had the time to setup and do REW again but will update once I get some similar comparisons.

About the tactile feel you may recall that I was all worried since the last time. Now even at my non-nearfield placement of subs they are hitting hard and sharp that I may actually prefer this setup. Music sounds great and with movies, my heart rate usually goes up after a 15 min demo I get every morning before heading to work, an excellent caffeine substitute effect.

One cool thing I noticed was, when I turn off my amps so that the mains are quiet and subs are running, my shelfs from far end of the large living room rattle even at -30 db AVR MV (subs running 7 dB hot).

More to come once I optimize the setup and placement ...

thanks flydeep. ill give a read. that said some research has taken me to the fact that my laptop may not support more then to channel output.

problem??
((maybe a different hook-up instead of HDMI??

Thanks for that Tom!! I think it shows output capabilities much more clearly.

Thanks. I debated on including 100hz but did so for several reasons.

1)This maintains the same consistency for each frequency window (three measurements points each being 1/3rd octave apart).

2)A fair percentage of subwoofers users do incorporate crossover points higher than 80hz. I'd say 8-10%(ish) in my experiences.

3)Even if you use the common 80hz crossover in your receiver it is only a gradually slope, not a "brick wall". So 100hz will only be filtered by approximately 4dB(12dB slope) to 8dB(24dB slope). In either case, the 100hz performance would still have audible significance

4)The LFE channel has a bandwidth of 3hz to 120hz(in this context). This is not altered by the crossover points discussed above.

I also had more data from a test session Jim did on 6/6/14 for all the Power-X stuff. This gave me 3 sessions in the "cold" and 3 in warm/hot. Instead of trying to figure out how to most accurately average it all I just used the 3 warm/hot sessions and adjusted our CEA-2010 stuff accordingly. I can't say for certain way but when we measure in the cold we'll see (about) one decibel more at most frequencies. It may be the amp staying colder, something with our mic(s), something about air density, humidity, barometric pressure, or a few other things I'm trying to isolate. Best guess at this point is it will likely end up being a combination of several of these.

But just going with the warmer stuff (say 75 to 90f) will most likely correlate best with Josh, Brent, others, measuring because let's face it....not many guys are going to drag ten thousand dollars of test gear outside when its 45-55f.. We do most springs because we have SO MUCH stuff we need to get measured from each winter.

Hi Flydeep,

Thank you for the update. This is ONE of several things I forgot to have Jim measure last week during his 6/6/14 session. I most definitely want to try a brand new driver against a well worn unit. I don't expect to see much but we have been getting so many testimonials like this one....it is peaking my curiously. We (me) also forgot some orientation checks(for trips opposed) and some off axis stuff too. So we'll (weather permitting) set up again soon.

So it would appear that the XS15se has now been tested by Josh Ricci. I am looking forward to reading this review and seeing how this sub with the new driver performs. Assuming PSA's published data is corroborated, I think this will shake things up a bit in the ID market.

Congrats on triple XS30's!!! I don't think many have that setup yet.....Brian Fineberg time to step up to the plate and run with the big dogs!!

Glad these are meeting/exceeding your expectations. The output on music must be incredible....my single XS30 was.

Two of either will be better than one XS30 in every way.
flydeep's Avatar flydeep 11:14 PM 06-13-2014
Sealed seems the best option for your room size and listening preference. A pair of xs15 would be great. How much is your budget?

Depending on that, either a dual xs30se or dual xs15se. Depending on how loud you push it, a dual xs15se may be able to fill adequately a 2200sqft room.

Ping Tom...

Mercury - It also depends on the laptop sound card capability. When you go through the steps listed in the pdf for setting up the speakers, there is a step where you play a test sound for each of the speaker. Does your laptop play for each speaker independently in that test?

Sounds like you need to check your sound settings in the control panel....some of the REW guides have pretty good directions to walk you through checking your settings.

would there be much tactile feel with dual xs 15se with blue rays movies?


could these subs be placed directly behind the main speakers with out ill effects? im a bit tight on space across my front only 10ft... so the smaller foot prints helps..


and one day in the future if I went to quads would I benefit much?


thanks
basshead81's Avatar basshead81 12:22 PM 06-14-2014
The closer you place the subs the greater the tactile feel. The XV15se is going to have a 7db advantage in the 16-25hz, but the sub is bigger and cost more. The advantage the XS15se will have is deeper extension and more compact size, but 2 XS15se would not match the XV15se around its tune. I think the XV15 will do a better job for blu rays, but with your room and size listening habits sealed will work. Quad XS15's should net some solid output down to 10hz. I think Bear and myself are on the same page, we do not feel sub 15hz is that important. Some want to experience everything that is on the disk, but for my room I do not feel its worth chasing frequencies that you might only experience for less then a minute on a disk and that is if the disk has content that goes that low. It all comes down to preferences, goals, room size, waf, and budget.

Another thing what Tom mentioned was that the sealed subs sound slightly better for music. That's where the listening preference could matter.
