Are crossovers set from the receiver or on the sub itself (or both) and what do I set them to? Many thanks.
For the most part, I agree with kmfellows.
However, before running MCACC I would first find the best viewing/listening position for your room (search the 9G Pio Elite thread for "viewing distance"--I have a post in there listing all kinds of distance viewing calculators--for instance, for a 60 inch Kuro, the distance comes out to be about 7.5 feet). Try to make sure you are NOT sitting at a multiple of 1/2 (i.e. 1/4; 3/4; 1/8, etc.) for ANY dimension of the room, and don't sit along the back wall. For example, sitting at the exact middle of the room is almost always a suboptimal spot to be, whereas the 1/3 or 2/3 position is often pretty good.
One you find the primary listening position, find the best placement for your sub by putting the sub at your primary listening position, and going into your Pio's setup menu and using the sub test tone. Crawl around with your ears at subwoofer height near the boundaries of your room, until you find the spot where the bass sounds best to you (tight, full, but not bloated). That's most probably the best spot for your sub. Put the sub there, and set your phase to 0 and the gain to about a quarter to half way up (depending on your room size).
Then, place your fronts on either side of your display and toe them in so their paths would cross just in front of your listening position. Place your center and aim it with a laser pointer to your seated head height at your listening position.
Make sure sub and LFE is on in your setup menu and check your connections again (make sure you have the correct polarities in your speaker wires).
Now, you are ready to run MCACC (use a tripod to get the mic where your head would be at the primary listening position).
Once you run MCACC, check to make sure that it has selected "small" for your speakers.
I personally wouldn't worry a whole lot about the crossovers for your purposes--sometimes we get hung up on trying to hit a real low crossover point (or the THX standard), that we compromise the set up exactly where most of the sound signal is. While I agree with what kmfellows has stated, if your crossovers end up around 100MHz with MCACC, it's generally not a huge deal--just listen to it yourself and see if you like it. If you don't, change the crossovers in small increments--don't worry if you get lost, just run MCACC again if you forget the original settings.
MCACC will get everything set up well enough until you have a chance to read up a bit (I recommend http://www.audioholics.com/tweaks/ca...-up-basics-101
to start) Once you have the basic knowledge and acquire some tools, you can tweak to your heart's desire.
Hope this helps a little.
