I tried all sorts of shielding methods but the RF emission from my particular unit was so strong, it affected my remote's antenna which is 25 feet away!!
Unfortunately I can't individually tune each sub because I don't have enough cabling to run individual cables to each sub (for now at least!). I will look into running an additional cable. I didn't think that I needed to tune each identical sub individually since they are located symmetrically from my seating position.
Wow on that RF problem well I hope the BEQ powers that be can support that $1300 unit fully as those balanced connectors look nice.
I use Oppo 203 for my analog out signal and pretty comfortable (don't ask) with that, but in my heart of heart regret returning the expensive Oppo 205 for a 203 just for the cork sniffing hope of a little better subwoofer source. Oppo never had balanced subwoofer output, but maybe one of the driveless clones out there might do that someday.
I'm considering Monolith THX subs and they have balanced connectors.
Well with minidsp already in your system you have some low hanging fruit. With a two sub system there are theoretical optimum positions in rectangular room with opposing diaganol corners being a favorite. If you don't already have a mic you should get a umik-1 (fully calibrated from cross-spectrum is the best deal as it mimics $1000 mic accuracy). Its pretty easy and fun to measure the subs with REW, run their room simulator to model different placements, and then well the fun begins when you inidividually tweak those subwoofers with minidsp.
So hopefully when your system settles down you can look at those subs individually and how they are interacting. The measure and test part is pretty easy while the adjust process quite time consuming though their are very effective techniques for REW to do kind of a magic button and give you settings to import to the minidsp using a generated biquad file (and I don't understand biquads). So make plans to wade into this if you've not already done so as I'm sure you'll be very satisfied when its all said and done. For me having all those bass humps and dips smoothed out just allowed things like Atmos to image much better and I suspect even for stereo doing so will just make your other speakers sound great.
Those better setup subs will also get more benefit from BEQ.
I'm due to check my subs again as I'm pretty firm on my positioning and want to model what replacing one PB12-NSD with a ported Monolith THX 15 sub might gain me in low end response. I also need to try another subwoofer 12 step setup method from AVrant before using minidsp for further correction. This is like setting up from scratch and it will take quite a while as I can't use the REW magic button approach (don't ask). Feel free to ask me questions down the road as I'm an avid minidsp newbie expanding my knowledge.
I'll pass on one of my favorite cork sniffing minidsp tuning tricks for the BEQ heads. I call it wagging the dog. I came up with this because i realized my stock Umik-1 could be up to 2 db off at 20hz in how it measures, but based on a few articles the response may be quite accrate at 40 hz. So I use a high shelf to hand tweak this response (German 4K HDR Atmos recording by Dolby of Liszt and Beethoven Piano concertos a fave since engineer roll off one would assume not done in that 20-40 range.) You end up having to tweak by ear at reference volume. So getting that bass response just so will actually help your high frequency sound (bass reproduction affects how we listen or perceive high frequencies). I still wag the dog with BEQ and it helps. And when you think about it BEQ is all about have the most accurate low bass response. Here are my settings for this handy EQ right now:
So this wagging of the dog basically moves the response below 40 hz and at 40 hardly at all. This also can be handy if you are hand massaging your bass in minidsp and you just have more or less low bass in this range kind of working out as you use the parametrics settings to massage up valleys and bring down humps. And if you don't have a cross-spectrum umik-1 or other highly accurate microphone you want this to try to guess at your own mic's errors in the low bass. On my last tune I just had a natural incline in bass as I went down towards 20 hertz and so wagging dog helped correct that and deal with mic accuracy at the same time. (Even if you have a great mic I'd try this in one's house curve approach as you may listen above or below reference and this can tune.) I love cork sniffing stuff like this and nothing like getting your sound just so.
