paulbroke - the reply you recieved from MA is straight-forward and correct. You should not utilize the filter in the AW-12 since your Pioneer handles the crossover filtering (double filtering is to be avoided). Simply toggle the 'out' setting and just leave it (the frequency dial then has no function). The filter on the sub is only for those rare systems that do not have external filtering.
Thanks guys, and one more question.
Rarely, the blue light is flashing which is on AW12 watching the movies. For example; during the jurassic park movie, this has happened again after 10 minutes "silience" scene. Then it goes to light up.
I have selected "out" position and have calibrated the speaker setup without any problem. Is this normal?
paulbroke,
My AW12 blue light does not flash, it is always on.
I have checked the manual and cannot see anything about this, maybe a call to MA.
I have sent e-mail about this issue to MA.
After 10 minutes silent scene, the flashing lasts 10 seconds...then it goes to light up.
I've seen a few times before another movies but generally blue light is stable during the movies.
BTW, power mode is "auto" on the sub.
Hi ric71 i'll try finding you on av forums 
Cool. When you do just pm me.

I have Pioneer lx85 and MA speaker setup as yours. Could you check this;
While AW12 subwoofer is on standby (blue led is off), i go to home menu on the receiver and i enter to Speaker Level section (which is on Manuel Speaker Setup). Then i select the sub channel for test tone. Subwoofer is activating after 5-6 seconds. How is yours?
BTW, about flashing blue led light, i have connected coax cable from "SUB1" out (pioneer) to "left" input (AW12). I just read the manual, it says..." connect to "right" input". Maybe blue led flashing is because of this wrong connection...
thanx
It's always good idea to read the manual 
You are right RickyDeg,
But, i am not sure about the reason why this blue led flashing has happened (just 10 seconds)...
Hi everyone. Been going through this forum as I'm also one of the happy Apex owners,
although my setup is currently not as "expanded" as most people on here (2x A10 in combination with a very skilled BK XXLS400 DF, all in gloss white).
Reason why I wanted to jump in is because I have 2 questions:
I going to purchase the A40 center soon, followed by 2x R45HD as the rear surrounds have to be rather small (WAF if you know what I mean ). As the R45HD will only be used for rear effects I believe it should be ok, but wanted to know if anyone else on here has some idea's on it.
Second question concerns the receiver. I'm currently using a Marantz SR-4001 which was the first AV amp I bought. Although I'm currently happy with the performance, I hear that the APEX speakers shine when being paired with a more potent amp, so was looking at the next step in the chain.
I know the concensus is that the pioneers or Yamaha RX series are proper choices, I was reading rave reviews about the NAD T757 receiver. I'm going to have a listen within the next couple of weeks (purchase of a new amp isn't for the near future anyway), but was wondering if there were any people on this forum that have already heard the NAD or have some experience with it?
You are right RickyDeg,
But, i am not sure about the reason why this blue led flashing has happened (just 10 seconds)...
Well, if switching to the correct LFE-input doesn't help then I too would suggest contacting MA or your dealer. Worst case scenario: your unit is defect. The blue LED ontop should always be on, regardless if it is in stand-by mode or in full operation. I've never ever seen mine flash at all and it too is set to 'auto'. The LED on the back of the machine is the only thing that should be doing anything (change from red to green) depending on the input signal.
Hope it gets resolved for you!

Hi,
The blue LED should always be ON.
The standby LED on the back is RED when in standby and GREEN when a signal is received.
Although MA say connect to the right input, it should not make any difference, the sub can be used with a Y splitter cable to utilise the Left and Right inputs.
This would give a gain of a few dB in bass, I have checked this with MA previously.
Hope you receive a reply from MA soon.
Thanks RickyDeg,
BTW; You said that "The blue LED ontop should always be on, regardless if it is in stand-by mode or in full operation"
but when i turn off the AV receiver or pause the movie, blue light is turning off after a few minutes. Is this a fault?
If the blue led should "always"be on, my sub is faulty because it is the same since i bought.
