Wiim Sub Pro

[Wolf]

Also check out @Wolf work at DIY audio, I recall him using some GRS drivers with good results and you could even move up to 10" drivers in some instances .

I don't believe I've ever used a GRS driver, but I have used a lot of drivers. The last sub I built was a sealed box Dayton MX10 in 0.75ft^3 with the Dayton 300D-6 plate amp, stuffed and boost on.
Before that was the Overdrive10/Kilauea with the UM10-22. This O10/K has been remodeled for the UMII, and has been built by another forum member over there.

Should well outperform Wiim Sub Pro in the "bottom most" position

say from 60Hz and below - correct? Especially with a powerful amp and a bit of DSP bass boost?

But the Wiim Sub Pro will cover from that LPF up to 200Hz - better as mid bass coupler?

Stereo, co-located of course.

I suppose you could pair them that way with small satellites, but then you would have to have both subs front and center due to higher bandwidth.
The beauty of the bandpass at 60Hz (steep) and below, is that most stand mounts and smaller floor standers are starting to roll off by 60Hz, or are no longer pressurizing the room by that point. It just gets out of the way and does what it does.

I need bass reinforcement right up near 200Hz, stereo co-located ofc

but the separate units LPF'd below 70-80Hz - aka trueSubs - I plan to also test summed mono, and those I think could be freely placed, to better tackle room resonance issues.

After watching Erin's video, this sub is amazing with a Wiim Ultra in an apartment. I have four Wiim devices and the beauty of this is if you have a desktop system next to your living room system the sub can be used for both. (My apartment living room and office are combined). I have my Kef LS50 Wireless II in my living room hooked up to my wiim ultra and my Ascend Acoustic Luna's v2 in my office area. The room eq and auto adjusting on the Wiim devices for me has been pretty good. Push a button and forget it, with Wiim streaming built in makes this a great buy for me.

that's a lot of bang for the buck.
