I played with a bunch of cables, the difference I suspect is silver vs copper as all the copper ones acted the same and I dont have dragons with the right connector to compare to (and honestly I dont think I could mentally cost justify them, the angels were sort of the ok this is borderline overkill but …

Dear @Dustin_Symanski,
I have two questions regarding the Pro Sub Isolator I hope you can answer:
-
Will It be a one-size-fits-all-DACs, or will there be a different one for each MSB DAC?
-
Related to the above, for the upcoming Sentinel DAC it was mentioned in another post that it might get a dedicated/proprietary connection to the power amplifier and I was wondering how that would then work in conjunction with the method of connecting the Pro Sub Isolator to the system that was mentioned earlier in this thread?
Kind regards,
Ron

I don’t believe that the isolators are related to the DACs at all.
These isolators take speaker level output from the AMP, via speaker cable, and output line level signal via an XLR jack that runs to the Subwoofer.

Final production metal locked in. We made some changes overall to closer match the Cascade DAC. More heatsink area (just in case) and better ergonomics for the speaker lugs. Production will also have smaller lugs installed, these are comically large for this application

@Bones13 is correct! This is driven off of the amplifier outputs so DAC agnostic. That being said, any system with active subwoofers should be using this. From the Discrete to the Sentinel DAC.

I stand corrected.
Thanks for the clarification @Daniel_Francis !
And I guess any subwoofer can be made ‘active’ with the right amplifier.

I need to try this … did you get my email for the order
Received!
Would it not be possible to use a splitter on that output and feed the same signal to two subs?
Thanks!
@Hubbman of course you can, but it depends on your goal and objectives, I have a stereo pair where each sub only sees it’s corresponding main speakers signal as I take the sub input from the speaker out on the amp (similar to the MSB Pro Sub Isolator’s approach but I use a REL Airship as mine as not placed ideally for running hard wire). Other people use a single sub or several singles, but they accomplish very different objectives.
The room layout, the main speaker frequency response, the room acoustics are all factors, I want a broad and very precise soundstage so I run mine as a pure left/right stereo pair, with a very low cross over as my main speakers go very low but I feel they need some assistance at low volumes.
Possible yes, but not the intended application. Are you looking for multiple subs on one channel or is this a stereo pair?
This would be a stereo pair. I currently run these amps from the sub outputs of my Gryphon Preamp. I was looking at my options if I were to bypass my Preamp and go directly from my DAC to my amp. in this configuration I would obviously need a solution for my subs. I’m fine with sending the same LF signal to both subs. Ideally I like the idea of using two of your new sub boxes, but I find the pricing a bit much for such a solution.
@Hubbman, ok I will admit confusion, if you are splitting the signal (say right) you are not getting a true stereo pair, you are getting dual mono’s
Correct, but being LF and not full range the “sound” is non-directional and not as critical that L/R receive a different signal.
My current set up sends the same signal to both subs and it’s great.
Just trying to think this whole thing through..
Ahh, here @Hubbman I am going to be contrary (my opinion is solely my own), I find that while the subs may not be directional in the pin point accuracy sense it is definitivilibly placeable (ie if you close your eyes and play something like the Angie by the Rolling Stones which is highly spatially separated in the beginning, almost dual mono) you can definitely tell where the sound emanates from and in my opinion a single mono sub setup muddies the soundscape (the separation disappears as does the breath), if you have the ability to listen to the subs set up as dal mono’s vs true stereo you should give it a shot but the placement needs to be adjusted, for a stereo pair they ideally are wider than the mains (ie slightly outside and behind) the main speakers. vs dual mono’s should be almost centered
Well, well, well…. I must eat my words on this one!
I just double checked the output configuration on my Gryphon preamp, and it turns out that the signal being delivered to my subs is in Stereo. L get left information, and R gets right information!
Did I mention it sounds great?

@Hubbman so now that you are 3/4 of the way there, try speratating the subs and tell me if you prefer the sound, if so you need 2 isolators

Can you please share the dimensions of this device? And just to confirm, there is no electrical connection to this device, correct?
The only two connections to the Pro Sub Isolator is a speaker level input and a line level output. There are no power connections.
Chassis Dimensions:
Width:8.25 in (209.6 mm)
Depth:6 in (152.4 mm)
Unit Height (Without Feet): 2 in (50.8 mm)
Unit Height (With Feet:): 2.6 in (65 mm)
Hi Daniel,
Is this available for order? If yes What will be the MSRP?
Thank you!
