but in my opinion a 15" sealed would be great but if the 2 12''s are ported it would be almost the same. So either way you would be happy. My self I plan on getting one 12" Ti ported since its a little over priced...Joe
all depends on power dude. we have 2 12s with a 2500D hittin 151, and we hooked up a TI PRO 15 to it and it hit less. The TI PRO needs more power than 2.5k. Unless your talkin about the regular 15 Titanium. In that case, get the 2 12s, port em, have a nice day.
