We watch more TV/movies then anything else but we are more looking to fill out the bottom end of our Zu Audio Omen DW MkII's sound wise. We have neighbors close by and won't be cranking the system but we want to be sure to have clarity in our music. My wife really does not want the house vibrating or shaking and became concerned with some of the review videos I was watching where they were doing sweeps to show the power of the ported subs. That has me thinking that maybe sealed would be best for my wife but I worry our room it too big for a single ported sub. To be honest, I want to feel some effects from movies but I sure don't want my wife to feel like I overdid it and want to send back the sub.
What do you all think would be best for us and why?
S1812 seems like a good sealed sub. Would I be better served by spending some more for the S3012 and it's duel 15" drivers.
We could also do the V1812 if ported would be better for our room. Would the V18 IPAL be worth the extra for us. Sounds like an impressive driver but we are probably not going to be pushing the max of this thing and would rather have clarity then max power so maybe the IPAL would that better and would be worth it for us.
I think the S1812 is a great sealed sub. However, if you end up going with a single sealed sub, I'd go with the S3012 without the slightest hesitation. Here's why, although this doesn't necessarily tell the whole story.
Single 18....254in^2 surface area with 16.5mm total xmax
Dual 15's, 350in^2 surface area with 33mm total xmax(16.5 x 2)
The S3012 also has double the power of the S1812 and should have higher sensitivity as well. The cab is narrower with the smaller drivers, and 100% inert from the dual opposed design in case you want to put things on top of the subs. A single driver, 18" sealed sub when pushed will dance items off of the top.
However, in your large space, a ported sub will definitely provide a lot more feel for movies, which can always be toned down as much as you want.
With the new drivers, I think all of PSA's subs are going to offer superb sound quality on music.
Were it me, being new to subs and not knowing for sure which would be perfect, I'd order a S3012 and a V1512, demo them both, and eat shipping on whichever one you send back. No second guessing.
