Thanks very much for looking. I suspected as much. I’ll beef up the subs. I’ll try 4 dB to start. I’ll use this profile for music. Perhaps I should have limited Anthem room Correction from messing with any frequencies below 65 or so and let my mini dsp do the work.

I realize many not be familiar with Arc Genesis but just looking for general guidance. My smoothing choice may not be optimal and perhaps should attach the file. From others experience do the subs look a bit too low? Thanks for any thoughts.

I wonder if I could get any guidance on balancing my subs with the rest of the system. Subs seem a bit underpowered after running Anthem Arc Genesis. In brief I have 3 subs time aligned then EQ's on a mini dsp. They are aligned for the MLP only and so far can only use the Java drivers. I...

I redid everything. Sub 3 (KEF kc-62) I think was the culprit. It is a few months old but some sweeps at lower levels resulted in intermittent oddly low output responses. I boosted it by 5dB and all sweeps were consistent. Perhaps I should have it looked at under warranty, but it sounds OK...

Thank you for taking the time to do that and explain the results. The MLP is only slightly off ctr--my drawing was lousy. With your previous suggestions and the good output from sub 3 in the near field measurements using the filters and inversion on the minidsp, I wonder if the sub just needed...

I understand. Thank you for thinking about this again. Here is a quick sketch. Sub 3 is 11 ft from the MLP. The CAO largely dictates the allowable play in the sub locations. I have maybe 6" of flexibility. I may have left out a couple critical measurements. MLP ear level is close to 2.5...

Here is more information. I could work from home today and had a few minutes only. The low output in sweep sub 3 mystery was investigated with a modification of your suggestion. I didn't have time to get out the Umik-1 etc but used my phone as a rough dB meter. I used the white noise...

Thank you for looking at the data and taking the time to write back. I think I had the crossovers on the two powered subs (sub 1 and 3) to bypass, but I'll check they didn't get jostled by me when I did the gain match or my cat for that matter. I couldn't for the life of me get ASIO drivers to...

Thank you so much for thinking about this. I have a couch along a long wall on the side and two chairs directly in line with the Ctr channel. I put the U-Mik1 at ear level at one of the chairs (My seat) and designated that the MLP. The couch is close so took a measurement there. I hope to...

I redid everything and have attached the data file. I am puzzled about a few things. First how low the output was on sub 3 (KEF kc62). I had gain matched in the position of sub 2 (passive) with a 50 Hz tone. It is about 11.5 ft from the MLP and sub 2 about 2 feet. Sub 1 is about 10 ft and...

Thanks for the link. The mini DSP 2X4 HD is awesome. A bit intimidating to start but Hometheaterguru Ep 7 demystifies most issues and emboldens the non-engineer enthusiast to venture forth.

Thank you for looking. Perhaps the PEQ filters somehow were overzealous. Perhaps I should clear the filters and shift the house curve higher and see what happens. I wish I had not lost the sweeps. It sounds fine with music but a bit underwhelming for the one movie we watched since the...

Thank you for commenting. The PEQ filters cut the gain, but it seems excessive. Perhaps I should start from scratch and run more sweeps being sure the predicted optimal delays with the REW alignment tool worked ok.

The subs were gain matched with a test tone at 50 Hz. The yellow highlighted curve is for the 3 sub virtual sub after time aligning and the PEQ filters loaded into the minidsp. Isn't it fishy that the output of the combined 3 subs is so low at 50 Hz? Any comments most appreciated.

Some sub outputs on AVR's are not truly independent. Anyway all tutorials I have watched always recommended aligning all the subs first into one virtual sub and then it is OK to have Audyssey set the delay (distance) to align the virtual sub with the mains. (Can check with alignment tool on...
