Split Sub Crawl

[subharmonic]

Does this work? Can I put subs in multiple listening locations and crawl or will this just cause cancellation issues, weird modes, etc?

Do the crawl with the first sub. The second must be placed where it does the best job of smoothing room modes, and you can only know where the modes are and if they're being smoothed by measuring the in room response.
