After connecting the S1801 @ the front stage (above picture) without running Audyssey xt32 or changing distances on the receiver X4300h here are my first impressions:
Gain at 1 o'clock from 11 on previous sub, AVR sub level -1 from -5 previously, Room size setting small.
Atmos Demos (Amaze, Horizon, Conductor, GOT), Stranger Things (First Episode Intro),
1. It definitely feels like a bigger/fuller sound sub but it was not a day/night difference like the upgrade from my HTIB sub to the PB1000. That was an eye opener. From a rumble sound to actually felling. I don't know if jumping into the $500 sub range is were the fun begins or my first HTIB was really that bad.
2. At that location the TR feels somewhat like the old sub nearfield (behind the couch) but not that strong. I'll probably try to place the sub on that spot and test the TR. It should be impressive.
3. ULF is definitely there. I was briefly playing with a tone generator at 20hz and below, and then comes DW running, "Did you feel it... there was a small earthquake, appliances were vibrating all over the kitchen...
" I started LOL "It was you, ahhh??? That was the new sub??
So far, it's was not what I was expecting compared to my first $500 upgrade. This one cost 3x that so my expectations were much more higher. But also I don't know anyone with a better system to compare were I'm at.
Now I need to re-run Audyssey over the weekend and see... It's impossible at night here in PR
with all the "Coqui" and generator sounds ;c)
