While I went years going with whatever HPF was or wasn’t built into my rig, I figure for $100 or less I’d be a fool not to have that extra bit of speaker protection with the added sonic benefits that come with it. Have there been rooms that the HPF couldn’t tame without tremendously steep and undesirable roll off? Yep. Did I suck it up? Yep. Did my speakers thank me? I imagine they would if they could.
