Since in Preset 1 you have center sub=LFE and no L/R sub, Enhanced Bass does nothing. Since center sub=LFE sends bass management to your large speakers, if you select Enhanced Bass it would (theoretically) send large speaker bass to where it already is. You can't use Enhanced Bass for Preset 2 because you have no large speakers. Yes, Emotiva should remove the option of Enhanced bass when you have a lone sub output set to LFE. It has been reported.

Great that you're trying out the center sub LFE thing! Looking forward to your impressions. This crash with 3.0.13 .... happens to me about 50%. Whenever I do a calibration I load the same filters to both presets. It either crashes on the first or the second pretty consistently. And same as you, it kills the XMC-2 and I have to hard reboot and also the EDNIB, Did the complete filter transfers.. A lot of bugging and restarts. I decided to uninstall 3.0.13 and reinstall it again. After that it worked 3 times in a row! First impressions was defined, tight and lost alot of sub rumblings. Hits hard when its supposed to.. Dropping keys on the floor doesnโt move my sofa.. Then I did a switch comparison with crossover and LFE modes. Wow! This was a night and day difference. A LOT LESS bass from LFE preset! With this I mean A LOT. Did the test with Harman 6db with the same filters on both. Movie: Star Wars - Rise of Skywalker: AppleTV 4k,4k HDR, DD+ Atmos, 20bit 48khz Scene: Intro when Kylo Ren flies to Palpatine and has a talk. Great scene! My first though was this must be wrong. Seems like Emotiva adds the +10db from LFE to both BM+LFE when they are mixed together. Is this something you have noticed? Maybe not with your setup!? The difference is so massive that you feel either something is missing or something is added on either preset. My setup is 9.2.4, crossover: LR at 50hz, C, SS, SR, FW at 80hz and TF, TR at 100hz. Two 12โ subwoofers, serially connected to center sub That would be really BAD ... add the 10db to LFE, AND BM? Like mix LFE and BM and THEN add the 10db? That would be so stupid. I sure hope not.

I currently am using L and R sub outputs to my two subs but have thought about changing to center and running Dirac again. Using just Center for LFE, that means your subs will not play with analog inputs, stereo music for example, right? I have DIYSG 1099's so they are fairly bass capable but I still like more. If I'm watching music videos, for example, I would want subs too. I have one preset with fronts large and center sub(s) on LFE. The other preset is set to fronts small center sub(s) on mono. Same Dirac measurement and filters, just different speaker settings in RMC. Is my underlined statement your intent with this configuration? "One preset with fronts large and center sub(s) on LFE" - Preset for Movies to get LFE content only to subs? What if you are streaming movies with no .1 channel?"The other preset is set to fronts small center sub(s) on mono" - Preset for Music with subs?

I want two presets because I may wanna use LFE for movies but also true 2.0 stereo music. Then also som extra stomp in the lowend with the crossover settings. Especially for music. But also for testing. Like you said sometimes there are special cases where I may want to use either mode for some reason.

Maybe someone else with the same configuration could do some tests also?

Maybe I have the answer, if I understand what you're saying. In my system I have subs connected to the center sub (LFE) output (through miniDSP) and so bass management goes to my L/R fronts. When I measure the fronts they look okay. When I measure all the small speakers the bass is elevated. I believe the reason for this is that bass management is mono. Since the bass from small speakers goes to both the left and right fronts in mono, bass from small speakers is louder by about 3db ... which is what I would expect. Here's a 5.1 measurement showing the increased bass. The center crosses at 200Hz and the surrounds at 150Hz. There's no way around this. I split my L/R and send one split to a combiner and then to the miniDSP so the L/R play to subs below 35Hz. The combiner compensates for the gain I would get from summing the two channels. But with the small speaker bass going to the L/R in mono it ends up louder. It would be better if bass management kept the bass in stereo (as it would if we had actual stereo sub outputs). I convinced myself not to worry about this because if I measure the L/R together the bass ends up the same as the other channels. And in reality that bass is likely to be mono most of the time anyway, the way music is mixed.

Easy mistake to make in the sequence of internal bass management and audio mixing. Oppo did it with the BDP103/105 line of Universal Disc players initially. Of course, they rapidly corrected it with a firmware update just as soon as it was reported A similar common error in Surround Sound Processors is to add the +10dB gain to the .1 subwoofer channel of multichannel DSD audio recordings. This is incorrect as DSD always contains full range audio signals (And for this reason much DSD multichannel actually is 5.0 with a silent .1 channel) In DSD direct mode, no subwoofer gain should be used. What must happen in DSD to PCM conversion is that -10dB is applied to the subwoofer .1 channel during conversion so that a standard Processor will correct for this later, (In DSD, the subwoofer channel is not attenuated 10dB in the source material like it is with DTS and Dolby sources (Which they do to give extra headroom (115dB rather than 105dB for the other channels) in the final output without clipping))

I've actually wondered about the +10db thing with respect to multichannel music. I just hoped they figured it out somehow . I have a lot of multichannel FLAC files, both 5.1 and 5.0; DSD both 5.0 and 5.1; and few multichannel SACDs. When I play DSD from my PC JRiver converts to PCM, and I have my OPPO 205 configured to convert to PCM also ... all so that I get Dirac processing in the XMC-2. It seems to me that all the 5.1 tracks play with proper levels. (BTW ... many excellent recordings from Channel Classics, NativeDSD and 2L) The measurements that I show in my earlier post reflect what happens when REW sends sweeps to the processor over HDMI. When you select output 4 in REW it sends it as the .1 channel and the processor adds +10db ... AND it rolls off the high end 12db/octave at 120Hz. If you want to see how the processor handles bass management when it's sent to mono subs, the way to do it is to set one of the speakers to small with crossover at 200Hz. Then turn off the speaker's main amplifier and measure that channel. REW will send full range sweep to the processor on that channel but you'll only hear what is sent to the mono subs. I have confirmed this is the proper level with no boost, and is rolled off at the top end according to the crossover frequency and the configured slope (12 or 24db/octave). And BTW, if you have no subs configured and fronts=large, when you measure output 4 with REW it sends the sweep to the .1 channel which must be played by the large fronts ... and the processor adds +10db. So if you have no subs configured, the processor adds +10db for LFE but does not add +10 for bass management ... whether going to large fronts or to mono subs.

"Arrangements" I tried this pattern the other day and it's working really well for my system with a very focused listening position. I have a very unusual L/R front speaker position which makes for some challenges with wide calibration patterns. The Impulse Response of the L/R can be thrown off by as much as 2ms. There's also a somewhat high-back leather couch at the MLP. I recline the main two seats of the couch and put a blanket over the back and seat when I calibrate. Low measurements down near the couch tend to have big peaks and nulls, so I eliminated them this time. And I temporarily put two 2x4ft absorbers blocking reflections from the L/R just for the MLP measurement. All 7 measurements are nearly on the same plane, not staggered as in this diagram, and the back two are narrower than the front two. The whole pattern is less than 3ft wide. The result was L/R Impulse Response within 400microseconds, good frequency response, and excellent imaging and soundstage. The only curious thing is the center channel has some odd peaks and nulls between 200-600Hz.

And, like you, I recline the back and place a blanky on the leather to reduce reflection. In a 9 point scenario I use the MLP, the front four (two high, two low) and the two high rear points for a total of 7. This has been the maximum for me. I've tried the scenario with more points over a greater area but that was fraught with less success. I am planning on trying more points in-between the ones I have been using to see if any change can be determined.

But why would anyone like to lower the LFE globally or anyway really? We need a similar setting for BM levels. For those with MiniDSP I guess itโs simple, after Dirac calibration just go into the MiniDSP settings and lower output โ3db times the number of subsโ. Was it -3db for each sub, -6db for two or -3db for the first pair? Just tested Dire Straits - Brothers In Arms SACD 5.1. DSD Direct seems to have subtle tight bass, about the same as PCM with LFE mode. If I change to crossover mode the bass is WAY higher. Excessive I would say. Tried to lower with the sub trim, about -10db and then starts to sound the same.. Even so, a little more thump with crossover settings. Iโm not so sure I have only 3db difference. Atleast 6db! Another thing.. Also noticed in trigger setup for active speakers, Front Wides isnโt even on the list. They are always on.

Yes that LFE level placement is odd ... and why is it only cut with no boost? I have played with Dirac curves and purposely dropped the sub level for better smoothing of nulls, with the intention of raising it back in the processor or miniDSP. MiniDSP 2x4HD allows you to boost but my 2x4 Balanced has only cut. So I start with the sub levels in the miniDSP a few db low so I have some range to play with.

I wanted to check if something was wrong with my preset. So I changed to LFE preset to have small fronts and mono sub.. No excessive bass! Heavier bass than LFE mode but not excessive. Hmm.. This needs to be checked. I thought it canโt be Dirac because I used the exact same filters. Went in and checked all settings again. Speakers were correctly setup. Volume ok.. Wait no it isnโt! Center sub was set to 8.0db!!! This means 8db plus the BM addons for multiple subs. Then Harman 6db curve on that.. Iโm very certain I set everything to 0 before running Dirac the first time on the second preset. But I did not check the values after I changed my Subs to center sub, just assumed it would still be 0. Seems like it picked up an older setting from when I used DSPeaker bass DSP. Well after this blunder I can safely say the difference is a lot less. Crossover still has more and heavier bass. Due to previous reasons. I will report to Emotiva.

Is my underlined statement your intent with this configuration? "One preset with fronts large and center sub(s) on LFE" - Preset for Movies to get LFE content only to subs? What if you are streaming movies with no .1 channel?"The other preset is set to fronts small center sub(s) on mono" - Preset for Music with subs?Yes, and no. I want two presets because I may wanna use LFE for movies but also true 2.0 stereo music. Then also som extra stomp in the lowend with the crossover settings. Especially for music. But also for testing. Like you said sometimes there are special cases where I may want to use either mode for some reason. I changed my sub output to Center and set Preset 1 for LFE with fronts Large and Preset 2 for Mono with fronts Small. I just finished running Dirac - will see if my bass response improved over using L and R outputs set to Dual Mono.

I just finished running Dirac - will see if my bass response improved over using L and R outputs set to Dual Mono. I got a lot lighter and defined bass. Lighter probably because the BM to subs raises the SPL by 3 dbโs (as marcl measured). To me it sounds more โnormalโ with LFE. But some may prefer the more โboomierโ output from crossover+BM. Anyway, I have reported this to Emotiva. I hope we can get a fix for bass gain or/and an option to change BM level. marcl : I also asked for gain to LFE and BM in these features.

Ok going back to Dirac v2.5.3 fixed my center image issue.
Hopefully Iโm done with Dirac measurements until we get DLBC (whenever that is).
I guess I can go from here to v3.0 and forward until the image issue occurs but I hate running Dirac so hopefully Emotiva/Dirac will figure out what the issue is. Itโs clearly an issue but hard to pinpoint.

Itโs clearly an issue but hard to pinpoint. Can you be sure it's apples:apples? Can you load measurements from 2.5.3 into 3.013 or vice versa? p.s. I find running Dirac measurements relaxing. I used to do it during Webex calls when I was still working.
