The SPL is quite high, but I really haven't measured it after I got 3 of that Plus/2.
I have placed an order for 2 x PB13/Ultra and 2 x PC13/Ultra, so I will probably measure the SPL when I get those. It isn't very important, as long as it sounds clean and tight (which is the goal, more subwoofers = more headroom and more accuracy)
By the way; I have got myself a decent rack for the components, so it actually looks's a little bit cleaner in front.
The most impressing for me isn't the SPL from the subwoofer's, but from the center speaker. 100 dB/watt sensitivity, and a internal amplifier on 250 watt makes the shooting in Open Range a physical experience I've never heard anywhere else (you can include the top models from Revel, JBL, Focal, etc.) The driver is a 12"
