Curious if this would work ok? Has anyone ever tried using a high-level sub connection in conjunction with Ultra's sub out features? I'm not sure why it would be an issue but thought I'd throw this out to the Wiim hivemind before trying it. And before anyone asks, I've indeed used Wiim's sub out to connect all 3 subs but didn't prefer the sound to high-level connections. For more context, the 2 subs I'm running now are both Velodyne CT100's, with their in-built sub management, connected in stereo via high-level to a dual mono amp. I have a 3rd sub (Mirage BPS-100) at my desk across the room and an RCA sub cable that would reach it just fine. In the past, I've connected my Ultra's sub out to all three of these and enjoyed the relative smoothed LF response it provided. That previous configuration, however, never seemed to sound quite right - the bass notes were all a bit, i dunno, muffled and rounded-off sounding, even after endlessly tweaking the Wiim sub management features. Going back to high-level connections and using the onboard sub management features of my Velodynes fixed this for the most part but I still can't help wondering if I could bring back some of the room response benefits if I connected the Mirage via Wiim's sub out. I would likely keep the Mirage's volume pretty low - just enough to excite the room modes a little.
2 subs currently connected w/ high-level, how about a 3rd through Ultra sub out?
Well for anyone that stumbles upon this in the future: I've connected my 3rd sub into Wiim's sub out. As mentioned above, I have 2 subwoofers connected to my (2.2, now 2.3) system via high-level connections, and the third at the opposite side of the room is connected via Wiim's 'sub out'. My 2 main subs are crossed over at 65 (on the subs' crossover knobs) because I get pretty good LF in my mains. My 3rd then is crossed over at the same point in Wiim's in-app sub management. I've of course toggled on the "Main Speakers Output Bass" option in the app in order for the 2 front subs to receive the low frequencies. I guess one *could* also toggle on the "Subwoofer Bypass Mode" as well and use the 3rd sub's onboard crossover, but using the in-app features makes more sense for me so I can keep the in-app crossover point at 65 for my main system and keep the 3rd sub's onboard crossover at 80, which is my preferred x-over point for my desk's system (which shares that sub). For sharing the subs, I'm using an off-brand passive switch from Amazon that seems to be noise-free.
FWIW: my main system is a Wiim Ultra feeding a Primare a30.2 amp via a JDS Labs Dac 2, with speaker cables running first to my Velodyne CT 100 "from amplifier" inputs and then from those subs' "to speakers" outputs to my Sound Dynamics 300ti's. The Mirage BPS-100 has now been added via the Ultra's sub out. My Desk system is a Wiim Pro feeding a Loxje A30 amp/dac which drives Paradigm Atom V.5's and, through it's sub out, the Mirage.

After reading your opening question, "Has anyone ever tried using a high-level sub connection in conjunction with Ultra's sub out features?", I figured you're probably experimenting on your own here. I'm wondering about the experience of a dual-sub/2.2-channel setup vs my main 2.1 system in my listening space, and I guess I'm unclear on the need outside of home theater effects?
In any case, it's cool that you took time to come back and share a follow-up to an unanswered querry

.How exactly are you getting all two or three subs aligned to each other then the 2/3 subs aligned to the speakers? And then applying EQ?
Appreciate it. For me, the multiple subs is less about 'more bass' and more about smoothing out bass response within the room. I have kind of a weird main room (open layout) situation and the multiple subwoofers has proven useful in solving for room modes.After reading your opening question, "Has anyone ever tried using a high-level sub connection in conjunction with Ultra's sub out features?", I figured you're probably experimenting on your own here.

Do you have REW frequency response of one, two, three subs, then with the main speakers + subs?
Without aligning them, responses on mine was awful. Worse than just the one sub
Indeed. When I have the budget for a minidsp, that's what I'll end up trying. None of these subwoofers cost me more than $100, so this ended up being my budget solution. Also, based on my attempts so far to solve for room modes via room correction and EQ, I'm not completely convinced DSP will be a silver bullet for me.
Good question! My 2 front subs are pretty much physically aligned and, to my ears, time aligned with my mains. As to sub #3, I used Wiim's sub sync feature (with the 2 front subs disconnected) and it seems to have worked well.
My two subs are physically aligned with my towers as room, but in minidsp hd the two aren't the same delay.
Without setting up response was awful (phase to 0 on all three) , peaky response, with narrow frequency say 40-90hz +/- 20db , and the third was cancelling out the front two. after aligning and EQ was flatter and wider response overall 10hz-120hz +/- 3dB , so it makes a massive difference Although I can understand not wanting to spend £300 on a device where the subs are £100 each, my subs are pretty high end ones so cost for minidsp was a small fraction of the sum of the three.
