Is this a bug in calculations by Audyssey?
I think i have read pretty much everything on the net about Audyssey but i seem to be the only one having issues with way too much bass when I use dual subs.
I have a onkyo tx-nr 1007.
I am using a satellite, Atlantic technology 4.5 speaker system + 1 extra NHT Subwoofer.
With all the calibrations and positions I have tested the end result have always been way too much bass.
If I only use the Atlantic sub it sounds pretty ok but if I add an extra to get more headroom and dynamics it sounds crap.
Onkyo Tx-nr 1007 should supports this and should do individual measurements for each sub regarding frequency,distances and volume.
Yesterday I did another experiment by unplugging subwoofer nr 2 from the Tx-nr 1007. (total volume of bass went down)
Tx-nr 1007 was still configured to play with dual subs but one sub was physically disconnected.
When I changed the setting in Tx-nr 1007 from 2 subs to 1 I expected volume to go up on the remaining subs to compensate for the lost volume but nothing changes.
As a matter of fact the onkyo Tx-nr 1007 sets exactly the same volume to each sub no matter if it’s one or two connected, if they are measured together or just one by one.
Is it me misunderstanding something or is this a nasty bug in the calculations for the Onkyo Tx-nr 1007?
Please advise me.
I got this explanation from a member at AVS -Forum.

The implementation of Sub EQ HT in the x007-models is only partly done, they left out the part where subs should be pinged together and have the trim levels set correctly.
Basically I think you have two choices: either you would have set the level of subs manually after Audyssey or use a splitter from PRE OUT SW1 to both subwoofers.
Onkyo finally implemented Sub EQ HT in the x008-models.”
