ASIO is flaky, just ask anyone in the REW thread (which is where you should go at this point). Make sure you have the latest version, reboot several times, sacrifice to whatever god(s) you believe in. Usually works eventually.
Yes, it's frustrating when you just want to get going.
Hang in there. Good luck.

What’s the issue, error messages or it’s just not showing up under devices?

Also what laptop do you have, what version of Windows, 32 or 64 bit, what version of ASIO, what version of REW, etc, etc..

I spent most of the time as first verifying, while reading through the guide I have linked, that Windows was correctly set in the audio section. Then loaded the ASIO drivers, started Rew and loaded the right calibration file for Umik. Then started troubleshooting Rew settings. After some getting back and forth in Rew, restarting the program, all the flags were green in the settings. Ready to go.
Then I had to spend all of my time in some other less amusing job!
Good luck

thanks

windows 7 professional x64 is on a Desktop no laptop.

Asio 2-14
REW 5-19 with JRE

If I play any audio source I get the audio to come out on the Denon so at this point at least I know the HDMI connection is working plus I also get the TV to display the background of the computer.


In the first step where it say Output I get two option on the drop down, 1 not connected 1 and 2 not connected 2
On the input I do get the UMIK option so I guess the problem right now is the output

Where is the REW thread?
Now I wonder if the miniDSP + UMIK would have been much easier

I guess is time to see what I need to sacrifice like LastButnotleast recommended

So what is everyones thoughts on two of these in the VBSS box? If you had 8 in 4 vbss box's would it be better then 8 in sealed boxes? I know someone modeled it but not sure if it was decided that it was a good idea or not.

The VBSS is 6 cuft with a 20 Hz tune. With two drivers at 3 cuft each I would be inclined to chop 3 or so inches off of the port length to raise the tune closer to 25 hz for maximum bass output.
Ultimately the VBSS will give better performance than sealed, however it is more complicated to build and is at least double the size. Let's call it an oval peg in a round hole, as opposed to the sealed option which is a square peg.
To really optimize these drivers for low bass output you need a large box, in fact one driver per VBSS is about right.
I think most people are finding that the drivers and amplifier power are so cheap that the sealed configuration is just easier.

well finally got the REW working, just before I threw the whole thing in the box and send it back.

Now since this is more pertaining to JBL multiple driver setup
How are you guys taking measurements?

set the UMIK in the middle of the room and have all 8 drivers go
Or do 4 driver at a time? UMIK in between boxes?


refresher I have 8 JBL, 4 boxes, each box under a speaker they serve as speaker stand so 2 boxes up front for left and right two on the sides for surround.

from REW I am able to have all 8 play at the same time or I could unplug 1 channel in the iNUKE to only have 4 drivers On.

Thanks.

12" JBL speaker $29 on black friday at Bestbuy

Just for fun



Definitely don’t know what I’m doing still have to play with the DSP and with XT32

That measurement was Raw no room correction and lots of crap around the room.

No, what you need to do is read and follow Jerry's excellent guide to REW.
Then continue to post in the REW thread, not here.

UMIK goes where your head is when you sit and watch/listen. Anywhere else in the room will yield different measurements and what you care about is what you're going to hear.

Assuming they pairs are equidistant from the MLP I would eq the front pair as one input and the surround pair as another, this will allow you to play wih delays if the surrounds are closer to you than the fronts.

That doesn’t look awful before PEQ. Ideally you’ll measure each individual amp channel at your MLP (put mic at 90degrees [pointing towards ceiling] exactly where your ears sit during listening) [make sure you have the 90d calibration file loaded into preferences]

So measure each channel individually, apply PEQ, measure both channels together and make fine tune adjustments. Remember phase and delay is either your best friend or absolute worst enemy.

I have to have my phase at 180deg on both channels, you should read @Shreds thread called “INUKE 6000 amp rundown” there’s a lot of useful information in there from measured wattage, phase, delays, PEQ filters, low shelf and high shelf filters to make the amp flat to 10Hz, etc etc.

Also what @Pradeep2 recommended about having 4 drivers per group for delay is a good idea assuming they are equidistant. It’ll take time but you’ll get the hang of it.

Also remember cut before you boost w/ PEQ.

woops I don't have them wired like that,
one channel is the 2 on the right side then the other two boxes on the other channel.
So 1 channel front and back, other front and back


was not aware it would have been better two front 1 channel then 2 on back another.

Trying to visualize how to do that.

I could easily move one side to be front left and right but the other to be rear surround i am pretty sure I would have to rewire the cable run would be long I think.

New project plus on top today I received my surround speaker so I have to wire those as well.

Update:
Page 20 post 585
The wire in between boxes would have to be about 30ft long plus the wire to the Amp another 5ft or so.

On the current setup the wire between the boxes is about 11ft

Would that cause any issues with the Amp having one channel with a shorter wire than the other?
I am using 14 pure copper wire.

Ha, so I spent a little more time EQ'ing these subs..

I think I need to actually go back in and start from scratch. The picture only shows to 15hz by 10hz it drops off a bit more, I tried to add more to the 35hz area to smooth that out. Im not sure why theres the huge fall off around 60, maybe my LCR speakers having a crossover at 60hz? I definitely dont have the 60-70hz spike like others.

I went upstairs to get food while hitman was playing...Ive never quite felt the floor shake like it did.

These are 8 12's up front about 10" out from the front corners in 2 packs of 4, all behind my screen which is nice

I dunno...thoughts? I think the words "house curve from hell comes to mind" which is why I feel like starting from scratch. Room definitely has some thump.

EDIT: or maybe im reading the graph wrong, I always went by the top line.

Set the polarity at 180 degrees in the software and see what that does for your 60 hz dip in relation to the mains.

Im not sure why theres the huge fall off around 60, maybe my LCR speakers having a crossover at 60hz? I definitely dont have the 60-70hz spike like others.

I went upstairs to get food while hitman was playing...Ive never quite felt the floor shake like it did.

These are 8 12's up front about 10" out from the front corners in 2 packs of 4, all behind my screen which is nice [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]

I dunno...thoughts? I think the words "house curve from hell comes to mind" which is why I feel like starting from scratch. Room definitely has some thump.

EDIT: or maybe im reading the graph wrong, I always went by the top line.
What crossover FR are you using on the subs and do you have Dynamic EQ on in your AVR or in any software/Inuke?
Subs are set to 120hz lfe. I am using both dynamic eq filters in the inuke but I have dynamic eq turned off in the avr.

Here's 2 more graphs. Started from scratch and ended up here, first one is just after audyssey, second is after multiple adj. Still get the dip, but if my mains/surrounds are crossed at 60 does it matter?

Oh btw, tried the 180 phase and no change.

I went to see blackkklansman (crazy movie) yesterday and was replaying the 7.1 intro at 0db. Nothing overpowering and still shook me...may run it for awhile.

Change the scale back to 105 - 45 in the vertical, and 0-200 hz in the horizontal. Is the SPL level calibrated in REW>? If so, I would bump up the level of the sweep, you aren't far off the noise floor of the room around and below 30 hz, so any data points there are suspect. What length of gating have you applied? ( windowing )



Without including the mains in the sweep, you will not see a change from reversed polarity, when measuring just the subs.

Dynamic EQ in the Inuke can give you a house curve that you were seeing in the other measurement you posted before. Depending on how you have it set.

And yeah where your mains and surrounds are crossed over will change the roll off the subs.

You need to see how they look together in a FR. If that last sweep was both you need to work on it. That is a huge dip in your FR.

Are you increasing the sub distance post-Audyessy and taking measurements to see how the FR looks? Usually increasing it will fix that dip between the subs and mains. You will probably get more upper bass out of the subs crossing higher like 80-100hz depending on your mains.

Guess I need to start reading again, whatever info I read I didn't retain all that well.

I'll try a 80hz crossover on lcr/surrounds tomorrow as well as reading more. Calibration sounds important and I'm fuzzy on it.

The short version of that is like I said above to increase the sub distance in 2ft increments after Audyessy and measure looking for the smoothest transition at the crossover and across the FR. They usually coincide from what I have seen in my own measurements. To fine tune, it go up or down in 1ft increments.

I have also noticed when making changes to crossovers it can have an effect on the sub distance and it may need to be adjusted. So if you add a crossover to the Inuke to cascade filters which can help cut out highs from the subs by making it a steeper filter. It is probably best to rerun Audyessy if you would do something like that and then repeat the whole process, It really does take a lot of time and experimenting and measurements to get subs dialed in.

trilkb Im no expert but that graph look all over the place :-)

see post
https://www.avsforum.com/forum/91-au...l#post56787016

after I ran Audyssey I got the red graph the tiny one.
Then after I mess around with the iNUKE DSP I was able to get the current graph but as you can see I still have that dib at around 55hz.
Following the suggestion over there I would get a filter from REW and see how that works.

I have 8 driver on that graph, I dont have a graph of just 4 and 4.

So I think it look pretty flat for being 8 diver what you guys think?
