Hello Mdrew,
Hope you are well. No problem. You may really want to talk to the people at SVS, they are very nice and will give you better advice than I can on which sub would work.
Website is www.svsubwoofers.com
The new SVS PB-2 ISD might also work in your situation, it is an $899 dual 12" box subwoofer with 600 watt bash amp without parametric EQ, as opposed to the single 12" driver PC-Ultra cylinder sub. The PB-2 ISD is 115 lbs and will take up much more floor space than the cylinder, which only takes up 16 inches of floor space and is only 68 lbs and is much easier to roll into place by one person.
I believe if you can live without the EQ for now, you can always add one later, that the PB-2 ISD would have enough power to suit your needs for a lower price. Although you will need enough floor space and another strong person to place it where you wish it.
If space is at a premium nothing fits better than a cylinder sub though, since they only take up 16 inches of floor space, all their volume goes upwards instead of outwards.
Lots of things to consider here. Also, that is alot of volume to fill with those high ceilings.
Later,
TonyM
