I've been waiting on these to restock and they finally did last week, but at $799.99 full price.

Definitely might go cheaper for BF ($679.99 in May 2021), but this is a great deal if you don't want to wait, or if you're afraid they won't actually be on sale.

12 is solid, if you have a pretty small room 10 will work just fine…even though the sub foot print is big/heavy lol.

Best bang for the buck sub IMO. I have two of the 10" versions in my theater room and they rock. Yes, they are very heavy too.

2 x 12s or wait for 1 x 15? Hoping the 15 will go on sale BF.

Dual subs usually sound better than a single sub, even if it's larger.

I went with dual 12's. Like the other poster mentioned, the general consensus is that dual is always better. Just depends on your space and listening habits though. For me, in a decent size room, the single 12" I have does a more than sufficient job.

Depends on your preference and expectations.
The 15" will dig deeper but two 12" would give a wider dispersion of their sound.
Placement is critical for best results and that 15" has a big footprint.

Thanks for the feedback. How big is your room?

My dedicated theater room is in an upstairs bonus room that is 18.5 ft long by 13.5 ft wide and a 8ft ceiling. I have a couch facing the 13.5 ft wall facing a 130 inch projector screen at 12 ft away. The room has a door and I would say is sealed very well except for a single window. I have a very old 10 inch Martin Logan Dynamo 500 with 120 RMS and 360 peak. It doesn't sound terrible, but I want to wake the neighbors babies when I watch movies or jam out. I love bass and want the most bang for the buck with a max budget of $1200, would be willing to stretch to $1400 to get X2 Monolith 12s.

Given the size of the room my initial game plan was to get a single 15inch ported version, what I am hearing is I should get 2 x 12s...

See post above for more details on expectations. I wont have issues with the big footprint of a 15. I was thinking with the sealed room and dimentions I would be better off with a single 15.

My dedicated media room is 17x17 and I have 1 of these babies in the back of the room and it completely rocks. Anything more would probably be too much for me. Extremely satisfied with this sub.

Keep in mind every environment and layout are different and would be impossible for me or anyone to tell you how these would sound or perform for you.
Based on your description and what you're after, either will "wake the neighbors babies".
You will "feel" the impact more with the 15", whether it covers your seating sufficiently is unknown.
If you need a wider dispersion, two subs makes more sense.
Hope that helps and good luck

If I didn't have dual SVS PB 1000 Pro then this was my choice. Instead of 350 you get 500 watts rms. Not sure how SVS is going to survive with higher prices when monolith is cheaper and powerful
