I scrape by with 2 subs, and think the array thing is cool but impractical for my current setup...I also am a Schiit Loki advocate, used rarely but it's there when I need it. Note that an array shouldn't exceed 14 subs as that is, well, excessive. 13 is the max, look it up. Or no...don't look it up.
Bass management with stand alone preamps
In researching an upgrade to separate preamp from an av pre pro (marantz 8802a) I’ve noticed that 1) most include no bass management 2) some include dual preouts but no bass management 3) some have a basic sub preout but no bass management. Are subs not popular in the two channel arena? I know in years past they were considered anathema but like every other issue in society views seem to have changed. Interested in how people typically integrate and if NOT running the mains with a high pass filter is common. Seems part of the point is to take that out of the amp and speaker and direct all that effort to the sub. If this has been beaten to death in another thread feel free to redirect. I have JL F212V2 subs which don’t have high level connections like REL appears to have.
