Can you give me ideas on how to install these speakers in my unfinished basement for atmos please?

Hi!
So my basement is going to be unfinished for a long time thus I wanted to try getting some atmos speakers with fuller sound than my Polk OWM3 which I need to crossover between 120-150Hz.
I wanted an Atmos speaker that I could crossover at 80Hz solid.
Looking for something not too heavy and if possible a big woofer like this 8" OSD Ap850

Just not sure how I would make it work so I can easily adjust direction/angle to MLP.
My other option was easier, the HTD Q65

Q65 Outdoor Speakers PAIR

When you need a little more thump and power handling, the Q65 produces a big sound in an outdoor setting. Its 6.5" polypropylene driver blends perfectly with the 1" titanium dome tweeter. These weather-resistant components are built into a resonant-absorbing cabinet that includes stainless...

As that ones has a threaded insert so is an easy swap from my Polk.
Or maybe this PSB P3

PSB Alpha P3 (Black Ash)

Bookshelf speakers

Which also has a threaded insert but I am concerned of the small driver.

I am running 6xJBL 590s and a Revel C208. The main speakers are driven by a Monolith 7x200W and the Atmos are driven by the Denon 4400h

Thanks for any suggestions on how to mount those AP850 (or AP650 maybe as I am beginning to think those 15" tall AP850s will look ridiculously large lol).
