I'm retrograding my 1960A back to its original Ipswich T75s, but will need to find another speaker for my 1x12 closed-back as I am currently using one of the T75s in it. (Ofcourse there is always the option to try out a new X pattern incorporating the T75, so I will not rule that out, yet for now I want to try out only one first.) After much looking into options from Celestion, EV, Eminence, among others, I think I will give Jensen a shot. So far I am undecided upon the Jet Raptor and the Jet Nighthawk. There are not many videos/sound clips out there, so I would like to know if anyone has tried one out who could shed some light upon the character/tone.
