Both of those ALLOW manual control...greater than Audyssey/EZSet/MCACC/YPAO give you.
Also, depending on the subwoofer, you get subwoofer EQ that is also manual with greater control than you get from the AVR.
Also, you must have missed "subwoofer placement 101"...
Response valleys are NOT correctable...other than by MOVING THE SUBWOOFER.
The x007 had the SubEQ partially implemented. Not sure if Audyssey didn't inform Onkyo of the proper way of doing or if it was the source code Audyssey provided to Onkyo.
The correct way is on the x008 series and the standalone Audyssey SubEQ unit:
1. The subs are individually set to 75dB AND
2, The subs distances are calculated individually AND
3. The subs are pinged at the same time
This is done so the correction filter is calculated with the summed signal. The idea behind this is that it is considered more ideal to run multiple subs with a monoular signal. Each sub will have its own peaks and valleys with the same signal so they help to compensate for each other and in the end give smoother bass response.
The x007 does this:
1. The subs are pinged individually to set gain and distance AND
2. The subs are subsequently pinged individually on the remaining mic locations.
So in this implementation a correction filter is created for each sub. The problem is that the sub signal is typically a monoular signal so creating a separate correction for each one may lead to uneven response.
If the mulitple subs are delivering a single sub signal, it is much better to create the correction filter based on the sum of the mulitple units. It will deliver a smoother signal in the end.
