(also, in ARC it has my sub at 160, but when I go into bass management on the MRX 720, it shows at 120)
I searched these out to try and understand, but I'm not quite and audio engineer...
What I am trying to get is some of the depth back that I have had with other systems. What I am experiencing is the bass on music seems 'short', like some lower notes that I know vibe and rumble, seem to come across and weak and minimal. (not sure if that all makes sense).
Any insight is appreciated, thank you!
Hi let me see if I can help.
Room Gain will increase the bass floor of your entire system up to about 200Hz. So if you increase room gain by 2.000 it will increase the bass of every one of your speakers. To verify this, just look at the graphs and then change the room gain and hit OK and then calculate and you'll immediately see the change in the graphs.
In laymens terms the order determines where your sub rolls off and decreases the volume the sub is playing and whether or not that decrease in volume is gradual over a larger frequency range like 1st order or very steep and dropping the volume like a rock, like 16th order at a very narrow frequency range. The lower the order the more gradual and larger the frequency range is. Pretty much every modern sub has it's own protection built into the circuitry so running as "flat" will let the sub play as low as it's capable of and allow you to get the most out of your sub.
In ARC's target window there is a setting for "High Pass". This is the Subwoofer frequency ARC will apply it's correction down to on your sub. So to see changes in the graphs change this value and recalculate and look at your sub chart. In ARC the high pass is the setting for the highest frequency allowed.
Low pass is the setting in the target window called "Subwoofer". For your system it sounds like it's set at 160Hz so this setting will lower/attenuate any frequency higher than 160Hz from getting to your sub. Try changing this from 160 to 250Hz and see if you like it better there. I've tried it lower than 250Hz and my system really muddies up and is lifeless at 160Hz.
The 120 setting in the MRX Bass management menu is the cutoff. This is where ARC has determined that you'll get LFE up to 120Hz sent to your sub. My previous comments delt with bass in general while this setting deals with just the LFE channel.
Try increasing the Room Gain and the "Subwoofer" setting from 160 to 250Hz in the target window. Both these setting can make a big difference in the bass and sound of your system.
