If hooked up to a laptop that's not plugged in, it's because the laptop has an "independent," battery supplied, power supply. Once hooked up to a generalized, independent power supply like a battery, it's a different grounding situation. Just saying.

IIRC, you mentioned two situations. One where the miniDSP was plugged into the USB port and one where the DSP was plugged into the wall outlet, hence why one situation has a ground loop issue and the other doesn't.

Which raises the question: does the miniDSP have flash memory that allows for holding programming information?

Commenting on that which I'm sure you're aware of, anytime, anything is connected to house wiring, if not using the same "outlet," to various degrees, a ground loop can develop. This applies, even if using the same circuit breaker but a different, same-said, down-the-line outlet.

FYI.....if two audio appliances, are on the same equipment rack, and electrically, they're connected, a ground-loop condition can appear. It really is that esoteric.

Beeman, I plugged the usb source into the same outlet as the 12 dc supply....the problem was the dc supply not anything else. I simply stated that the hum went away when I plugged it into the computer. so I went and grabbed my samsung usb charger,plugged it into the wall and there was no ground hum just like when it was plugged into the computer. Im fully aware how electricity works. Yes the mini dsp has flash memory, it can be unplugged without losing its settings.

Perhaps, but ground looping isn't covered in your typical course on home wiring. This explains the causes and cures:

That is correct. All of the general "specs"( weight, warranty etc) were taken from manufacturer/reviews. All of the output (2010-CEA) data is taken from third party reviews that have been documented on the internet(mostly at databass and audioholics). All of the output data is normalized in this chart to *2 meters, rms(not peak), drivers facing the measurement microphone*. If anyone wants to compare the output data to 2010-CEA data posted using a 1 meter/peak value....you have to add 9dB to all of the data. If A subwoofer had multiple "extension" settings(and data was available for all the options) I used the extension setting that most closely compared to the XV15. After all, that is the entire point of the chart.

The extension was probably the toughest one for me to try to figure out a fair and accurate way to express it in a chart like this. All of the frequency response curves are done outside so taking a standard +/-3dB off the measurements isn't going to be an accurate representation of what the end consumer could expect in an average room environment. If we did that the XV15 would be about 21-200hz. We can see that clearly isn't the case as there are plenty of measurements in this thread showing the XV15 offering extension down to the 14-17hz range. What I ended up doing was finding the -24dB/octave point for each model. I then magnified this to a -8db per 1/3 octave point. I used that for all subwoofers. I believe everyone would agree that once a subwoofer is rolling off at this rate (24dB/octave) you usually won't see much more real world extension out of it. I could have just increased the window to say +/- 5dB (that would have been a LOT less time consuming!) but I believe that most/all would agree that barring some unusual measurements looking for a true 24dB/octave spot is a pretty good indicator of what will happen in the average room.



I'll update the chart with all this information as time allows. As with anything like this typo/errors are possible so please don't hesitate to email me if something like that pops up.

The slight difference in extension is likely something in the mini-dsp. That is the only variable between measurements, correct?

Ordered Triax last night. Can't wait for it to arrive. It will be interesting to see how much different it is from my current SVS that I have had for years. Spoke with Tom a couple months ago and decided to wait till this bad boy was ready to go.

Only played with a few movie scenes and TV shows nothing to really stress it yet. I will play with it more today and get it setup just right.

Very happy with the choice and glad to support a company in Ohio.


That's outstanding skdmrklcy,

Excellent response. Nicely done!

 

Now, the most important question is: How does it sound compared to before EQ?

As you lowered that huge 30hz peak, your relatively raising the frequencies around it. Combine that with other EQ adjustments, perhaps the aggregated effect has put more demand on the system and therefore your rolloff is earlier...

Ray,

I know you asked a questions about the availability of the wood veneer options but I'm so far behind on this thread(and elsewhere) I can't even find it now..smile.gif

The Satin black will be considered our "stock" finish and we will attempt to keep that "in stock".

The five wood veneer options will initially have about a 10 day "lead time" We are not going to stock multiples of each of these to start. We will have partially completed cabinets ready to be finished(at the cabinet manufacturer's location) as they are ordered. Once we can determine which wood veneer options are the most popular we will try to keep those in stock for "1-2 day shipping" as well. As of today, the two Cherry finishes seem to be getting the most interest.

Anyway, during the preorder period, if someone makes the wood veneer purchase by say....June 20th(ish) their order should ship out with the first wave of Triax outgoing.

Thanks! Yea I was thinking it was related to the minindsp also because it changed the delay as well. No biggie, its worth the trade off for the improvement in response. The sound quality of the subs went to a new level...its amazing how much the bass bass tightened up. First thing I noticed was how much more even the bass response is between different music genre and movie
content.

I thought the subs sounded great before, but now its like I changed the whole sound system! Its amazing how room modes affect sound quality!! The mid bass slam is there like never before, every type of music sounds more even and full! If it was not for this forum and folks recomending REW from day 1 of loging on this site, I would of never knew what I was missing out on! I am really pleased with the REW/MiniDsp system as it is really easy to use and understand. Probably the best investment I have made...highly recomended! smile.gif

Hah! Being 6'4" helps as well as having my dad who is also 6'4" wink.gif

Plus, my work consists of sitting in my bedroom and doing computer stuff since I work from home smile.gif

I did get it hooked up though and listened to a few movie scenes.....still need to do some tweaking though but that will have to be after work today.

Tom, that's good to know I can still order the Cordovan until the 20th of June, I may just have to switch my order from the Satin Ash stock cab. $200 more correct? Congrats Noracuron (is that right) on your Triax purchase. guys I really need to know how difficult for a non savvy computer dummy like myself to actually learn REW and take measurements with the Mini DSP and mic. By the way BH81, what did that setup run excluding laptop, and if you don't mind me asking your level of technical expertise? I mean I'm bad with programs and running them. Should I just lay out the extra cash and get a stand-alone device that just goes in between reciver and sub?
Thanks Jeffrey smile.gif

I would call myself a techie but not a expert by anymeans. REW is free, the Dayton umm-6 mic was 80.00, and the MiniDSP was 155.00. thats what you would have in a older used antimode but way more adjustability and flexability. Both of these programs have extensive tutorials @ hometheatreshack.com

the mini dsp is a standalone device that hooks up between the avr and sub...you simply plug a pc into it to make your adjustments. Its really not that difficult at all once everything is setup.

Thanks Tom.

I was originally looking at the satin black and thought maybe my wife would want some input with a different finish. She said she thought black was fine, but after seeing the cordovan cherry I'm thinking about it for myself.

Thanks BH, seems like a very minimal investment for some good results, I will try to visit the REW site at HTS and download the software and give it a shot. So the Dayton umm-6 usb is the way to go for mic, is a stand reco'd? Thanks:)

Hey guys, I forgot to ask, are we talking just sub measurements here with the DSP and REW and Dayton mic, or is there the ability to do whole system setups, excuse the ignorance of topic

REW will measure the whole system. The mini dsp can be used for subs or main speakers.

Hi Guys,

There's a thread for that. wink.gif (On AVS)

I started a thread here on AVS back in January to teach people how to use REW and get the most out of your sub, along with an introductory course in room acoustics and acoustic models, and it has gotten a lot of traction over the last few months.

The buy-in cost is only about $100 which is for a USB mic as REW is free and you don't need any other hardware/software (other than a computer, of course).

There are a lot of helpful people and AVS member AustinJerry has created a very helpful getting started guide you should check out.

I cannot recommend Herb from Cross Spectrum Labs highly enough! He is great and for the same amount of money as ordering the UMM-6 from Parts Express or the UMIK-1 from Mini-DSP you will get a "TRULY" individually calibrated mic with not only the 0 degrees cal file (pointing straight ahead) but also 45 degrees and 90 degrees (pointing straight up like most people do and the proper method you also use with Audyssey for example).

He personally individually calibrates each mic and supplies a unique and individual cal file compatible with REW with each mic. His calibrations are very accurate and unlike that "batch" calibrations from PE or MiniDSP which aren't even accurate and only at 0 degrees which people don't usually use, the cal's from Herb also are accurate from 5hz to 25khz instead of 20hz to 20khz like you get direct from the manufacturer.

Also, if you are a member over at HTShack too, make sure you give Herb your username over there for an additional $5 off your order. smile.gif

I strongly recommend the UMM-6 mic as it is more accurate and MiniDSP has been plagued with calibration problems and things not lining up.

Anyway, to delve into REW and have a lot of help and support along the way, keeping it right here on AVS, visit us over in the thread at http://www.avsforum.com/t/1449924/simplified-rew-setup-and-use-usb-mic-hdmi-connection-including-measurement-techniques-and-how-to-interpret-graphs

See ya there,

--Jason
