I was going to say 140 is a good number at 25hz....sadly video looks to be @60hz.
These guys need to either do a better install/box and get some really impressive numbers or seriously re-think their marketing strategy. Won't say anything about the product since I haven't used them, but really who are they trying to impress? What's the MSRP on these 18's which are only capable of burping 140 with nearly 1KW (If you extrapolate this you'll get 143 at 2KW and 146 at 4KW, 149@8KW etc. and that's on paper not figuring in compression).
