Flanking subs are setup to blend generally in the 100-200Hz region, but in practice the blending region is shifted a little lower than that. Distributed multisubs are always used below 100Hz but usually below …

Re: My 3π adventure
…use such an arrangement and also include flanking subs.

Re: Subwoofers vs budget... where do you draw the line?
…two-way speakers, I always start with flanking subs. I mean, you can run the speakers with no subs at all if you're making an apartment system or something like that, but if we're talking stepping up a notch or two, start with flanking subs first. Don't…
