  1. Have been away for a while. I don't have that particular movie, so I can't test it. I did a similar check using the analyzer with War of the Worlds, which showed the high levels, but all channels were more in sync.
  2. Not to silly a question after all. Although I don't understand the underlying problem yet, it is related to the network adapter. I have a dual port adapter setup as a bridge. Each port has a MAC address port 8A and port 8B. Mac Adress 8A gets assigned a fixed IP address, and when both ports are bridged it's received the 8A MAC address, or it is piggy backing on the port with the MAC address assigned with 8A. For some reason this bridge doesn't seem to function. When I delete the bridge everything is fine, but with the bridge in place everything falls apart. More research needed, but at least I know where to look now. Thanks for pointing the simple things.
  3. All my IP addresses are fixed and pushed out via the router. I think that when windows resets a network adapter, it actually powers off and on the device.
  4. Yesterday I have taken the plunge into updating my computers from Windows 1709 to Windows 1909. All things went rather smoothly apart from some network/internet connection issues which could be resolved with a network adapter reset. However, I am running one PC as my central media library with; Kodi and a MySQL database and JRiver Media Center24. Now I have found out that I no longer can connect to these media libraries/data bases, via my network. Kodi on a separate PC cannot reach/access the MySQL database running on my central media server Jriver cannot being accessed via a browser on a different PC. Can be accessed locally via browser on the central media server Jriver cannot being accessed via Jriver with remote library on a different PC. Gizmo app cannot access JRiver running on my central media server. File sharing and internet all work between my different computers, and all can access files remotely from my central media server. (on my local network) Turning off the firewall on the central media server doesn't resolve this issue. Turning SMB1 didn't solve things either, and hasn't changed between version 1709 and 1909 Reinstalling MC24 didn't help either Installing the kb4554364 patch didn't help either Server and workstation services are both running on the central media server Anyone else who might have an idea about what to do? I am suspecting a service not running, or a new network security feature implemented that I am not aware off.
  5. Check, Check, double Check. All scene are fine for my subs incl bass management. I had to adjust the low frequency roll off for the subs with the War of the Worlds scene as they seem to be hitting x-max. Still the frozen scene is a troubled scene for some reason. It is not the frequency that is the issue, it is the level send to the amp that is troubling. It is (nearly) driving the amp into clipping and it al just sounds wrong. Send bass management to a second pair of subs (testing with this option at the moment), and it all sounds a lot smoother and cleaner. I think I might have found an indicator. The second lines ( on top of each other) below the cyan for Sub is the level for the Left and Right surround speaker. Their level is out of line with the surround back speakers, and louder than the main speakers. I'll have to check the setting on that.
  6. I can't really understand it either. I did an analysis of some scenes and there is nothing out of the ordinary. The third pic is the troubled scene, but the other scenes don't give me issues which is funny. Bass Management adds about 7dB on top of the LFE and peaks at -13.5dB at my preferred volume setting at the troubled scene. When I playback only LFE at 100% volume the LFE channel peaks at -10dB and doesn't distort. I am getting the idea that bass management is a bit funny and need to take another look at it inside JRiver. Which scenes do you mean with Tron Legacy, War of the Worlds and World War Z. I have these movies. World War Z has at least 2 grenade scenes in it. Can you give me a rough indication of the time line?
  7. !!! SPOILER ALERT !!! If you don't like to know some details about the movie you might not want to read any further. In Frozen 2 on Blu Ray( with the DTS HD master audio track) near the end of the film Elsa is saving Arendelle from a tidal wave by waving her magic. This moment is accompanied by a massive push in the low frequencies and pushes my subs into distortion. The problem seems to come from using bass management for my 5 speakers (excl Left and Right in a 7.1 setup). I have to cut the bass management down by an additional -5dB for each bass managed speaker to get rid of distortion, and this is at a volume level that is -10dB down from reference. No other movie has presented this problem. Deep Water Horizon, Masters and Commanders, Apollo 13, First Man, etc are all within limits without distortions. I am wondering if anyone else has encountered this problem and if this could be flaw in the mixing of the sound track?
  8. I think my previous posted might be quite some time back. The drivers are Dayton 15" RSS390HO, specifically meant for smaller enclosures.
  9. It has taken me some time as I had this planned a lot sooner, but I finally found the time to finish my subwoofers. It has been a nice project, although the bamboo floor boards used for the outer skin has proven to be challenging for my basic tools. The subs have the external dimension of 440mmx440mmx440mm, and uses timber legs to sit on top of a concrete paver (base) with rubber feet. I find this to work better on a floating floor instead of having them sit directly onto the floor. I did the same thing for my main speakers. They are made out of an 18mm MDF inner shell with 3D bracing, and are cladded with a 14mm bamboo flooring outer shell. They are externally powered by a Behringer iNuke power amp, which I still have to modify because the fans inside are too loud for quiet movie scenes. They weigh about 40KG each without the base.
  10. The methods I used are Research, Measurements, Try and Error. All my acoustics are based on the principle of absorption and random reflections (simplified diffusion). If you go about this yourself you need to do research to understand how and what works to which extend, then the best way to go about it is going step by step. Tackle one problem at the time, test-measure-listen-adjust-repeat. My ceiling is just a bunch of timber slats/strips with absorption behind it. You can use any kind of absorption, but the ones which gas flow values are know, are preferred, as you use that in (online) acoustic modeling software to give you rough estimates. The acoustic forum is a good place to start your research as well as google. Your best weapon is to know what works, and why, or what doesn't work and why. There are general treatment ideas for theater rooms which you can use as a starting point, and adjust from there, test-measure-listen-adjust-repeat. Edit: I forgot about Subwoofer placement and listen position, which can help out a great deal (for free), and some minor EQ at LFE levels where acoustic treatment is difficult.
  11. It has taken me some time as I had this planned a lot sooner, but I finally found the time to build my own subwoofers. It has been a nice project, although the bamboo floor boards used for the outer skin has proven to be challenging for my basic tools. The result however is pleasing and more importantly according to plan regarding my goals and expectations. I don’t really know how loud the max is, as I haven’t pushed things to the extreme, but it can reach 115dB at -3dBFS down to 17Hz. Why it is starting to slope down quite rapidly starting at 17Hz I haven’t figured out yet. It slopes down by 8dB rather quick and then start to level out at the SPL when I run a sweep starting at 10Hz. Due to acoustic treatment, sub placement and listen position the non EQ output isn’t too bad, and with a little EQ, I get a nice sloping curve which is +3dB at 20Hz. I haven’t EQ-ed the peak at 140Hz, as I cross over the subs at 80Hz with a 48dB/Octave slope. My system is tuned to output 80dB at -20dBFS instead of the generic 85dB, as I never listen at 85dB because I find it simply too loud, and usually have the volume control sitting at 75dB. The subs have the external dimension of 440mmx440mmx440mm, and uses timber legs to sit on top of a concrete paver (base) with rubber feet. I find this to work better on a floating floor instead of having them sit directly onto the floor. I did the same thing for my main speakers. They are made out of an 18mm MDF inner shell with 3D bracing, and are cladded with a 14mm bamboo flooring outer shell. They are externally powered by a Behringer iNuke power amp, which I still have to modify because the fans inside are too loud for quiet scenes. They weigh about 40KG each without the base. Not sure yet what I want to do with the old subs, as I don’t have any placement options to smooth out the SPL levels, and don’t need the extra output level. I am considering to use them as Subs for bass management for all my other speakers except mains, but I have to do some research to see if there is any benefit in that, as I have to reconfigure my system to a 6.2 setup with 9 speakers. I haven’t tested yet to see if there is a down side to running the surround backs in mono compared to stereo.
  12. It is surprisingly relaxing and calming to be in the happy zone. The rush is gone and I have more time to enjoy.
  13. I am not sure how changing the height of the LP is related to the back wall? Any movement of the LP towards the back doesn't help with this dip. I have made many measurements across multiple seats. My seat to seat variance is pretty good. Changing the LP (mic) from 90cm high to 145cm high is the first measurement that actually helps. I was leaning towards SBIR as well. I have done the reverse subwoofer crawl, but only measured up the half way height of the room (125cm) at the current Subwoofers positions, and not beyond that, which didn't show any significant chance. Neither did the testing yesterday where I have to pass the half way height of the room before effect takes place.
  14. I recently had the chance to test my sub build outside, with the mic place 1 meter away. I think the result is pretty decent. Blue line is the Win ISD modelled SPL output with an 800W signal. Red Line is the measured SPL output with an unknown wattage signal, peaking at 122dB.
  15. A: Not really, and that doesn't help either B: I don't have a bar stool, but it is a 4dB increase which is pretty good in a frequency range that covers a lot of instruments.
