it was with my 4th order, .93 each sealed about 16 ported,but i done it with out my wall peices in so i'll gain some there and i was peaking 4-5 hz to low.At 48 hz i pulled 148.2 but when i went up to 49 i dropped about 1 db if that telles ya how peaky it is.Im also building a ported box to put inside to make it a series sixth order.I'll post results,oh and what little i got to play with it,it didnt sound great but im sure its cause its geared for spl.
