This seems to account for the fact that pre BM the 100hz Xover setting always sounded the best in my room.
I, for one, am impressed at these findings Now, after the adjustments to phase have been calculated and applied across all speakers we no longer have to compromise by finding less that ideal ways to fix the problems. Raise the crossover above the dip and allow the sub to fill in the hole Move the L&R speakers in the room (often not really possible or ideal)ģ. Play with timings in an attempt to effect a better phase match (difficult and complex)Ģ. So whilst before BM the only options available to correct issues like this would have been:-ġ. With BM applied (Purple trace) however and all the BM calculations complete, you can see the improvement. You can see what "old dirac" was doing (Green trace) and perhaps explained why I was having to resort to measures such as tweaking timings in an attempt to ameliorate this issue to get things to sound better. However once you bring phase into the mix the picture changes. On their own, the L&R REW traces look very good and if I were to just look at the average of the two without bringing the effect of phase into the equation the combined average trace would look even more hunky dory. This is a good demonstration of how DLBM has resolved a phase issue created by my room between L&R speakers. Takes a while to get your head around that! If your processor works in ft/cm distance - by decreasing the sub “distance“ setting in ft or cm. I am only using three of the 8 dirac channels available, which I think is why it reports signal too low it can't get a signal. I'm running into a showstopper while trying to take measurements. If your processor works in ms delays - by increasing the ms delays on all speakers except the sub by the same amount, which really means you are “delaying the sub as compared with all your other speakers“Ģ. This is my first time using dirac live 3.0 (have used older versions) with my minidsp c-dsp 8x12DL. Increasing delay between sub and your other speakers means "making the sub start later relative to all your other speakers".ġ. So adding distance (ft or cm) to the sub setting is the same as reducing the delay (ms) setting of all of the other speakers. If the sub is farther away, the processor will take into consideration that the sound it emits will have to travel a longer distance and will have to start sooner when it does its calculations. If your processor works in ft/cm distance - by increasing the sub “distance“ setting in ft or cm. If your processor works in ms delays - by reducing the ms delays on all speakers except the sub by the same amount, which really means you are “reducing their delay time as compared with the sub“Ģ. Reducing delay between sub and your other speakers means "making the sub start sooner relative to all your other speakers".ġ. Different Processors will generally use one or the other (Delays in ms or Distance in ft/cm.) so you need to select and use the correct method. I have tried to convert this too.please let me know if I have messed up!ĭelay (ms) works conversely to Distance (ft or cm). For use with non Lyngdorf processors I would substitute amplifier delay for “all individual speaker delay settings in ms other than the sub”.
