Thanks for the graph poges. I knew it was deep but didn’t think it was THAT deep lol. It’s pretty sweet with DSU.
I could see my drivers moving slower than what I was feeling/hearing so that's what prompted me to graph it. I wandered around my listening area trying to pick it up, but it's just too low of a frequency to hear. In some spots I think can feel it tho. Kind of like the sensation of being buffeted by the wind. More like pressure in the ears than anything heard.
So of course I plugged both ports on both of my subs, flipped them to eq 1 and turned it up to -5. I sit ~14' from my speakers, so that's cranking it up pretty good. They took it like champs! 5 or 6 plays in a row and fins on back were only warm. My subs will measure pretty flat to 16 hz plugged like that. I didn't turn it up that loud with any ports open tho. It was pretty intense, lol.
I did pure/direct also so my towers were playing full range and took the grille off one of the 8" drivers on the side of the towers so I could watch it while playing that track (might as well be stacking gel pillows in my seat...
). They weren't as impressive to watch as the Hsus. In fact there really wasn't a ton of excursion, tho they were definitely moving. They handled it well and didn't misbehave but there was nothing below about 30 hz or so. They must roll off pretty steeply after that.
