I have never heard of this approach before. What problem are you trying to solve?
I'm surprised you hadn't heard of this technique. There's a bunch of stuff on the Internet (pros and cons. I just want to try it). But I think this article
will answer a lot of questions.
My speakers are smallish but I find the higher I cross them the clearer everything sounds. I currently cross them at 100Hz so I want to try higher but then I have the localization problem.
My preamp has a digital in and has 4 outputs L/R and configurable L/R. The configurable L/R can be full signal or a low-passed signal in either mono or stereo. The latter would be low-passed L and low-passed R (actually, more configurable than that but for this purpose that's what matters). So I would do that and feed each signal into its own TBI. As an aside, the crossover in the preamp can go extraordinarily high (like 9999Hz) and supports a variety of types BW,LR, and orders (1st,2nd,4th,8th).
The preamp can do delay as well so the subs can either be co-located or placed anywhere, I think. I'd have them co-lo to make my life simpler and that's all my room supports anyway.
I am not sure that there's an actual problem I'm trying to solve. I've just heard that "stereo bass" can really open up 2ch soundstage and detail.
My preamp is a Lyngdorf and I'm inspired by the Lyngdorf speaker system (review)
Again, please don't judge. It's just a configuration I want to try out. I've read about how so-called stereo bass makes no sense but I'm having a mad scientist moment with this, if I ever to try it.
