Sorry if this has been posted somewhere already. PE has just released some new drivers, The Titanic MKIII in 10" 12" & a new 15" version. I have been waiting to see them do something in a 15" that would outdo the current DVC 15" Dayton & it looks like they have. Power handling, 800watts RMS 1,100peak Le:3.84 Impedance 4ohm Frequency range 19-500hz Fs:19.93 SPL:91.7 Vas:7.79cu.ft Qms:5.89 Qes:.41 Qts:.38 Xmax:20.5mm I've been looking to build an IB system & planned to use the Dayton IB subs or DVC's, but I think I may have found a new friend. I'm not to good with WinSID but I'm going to play around & see what I can come up with compared to my DVC.
