HI folks..Hope y'all are good through this crazy world.. I pulled some speakers from an old Conn Organ..50's i believe.. The two speakers in it look pretty nice..info: Jensen Alnico 5 PM speaker Concert Series code-220537 7a 41 P10Q C5824 These are in excellent condition..(the organ was my Aunt's..in her basement since forever (im 60)..unplayed..my cousin took it through two moves and then gave it up to me..i was hesitant but took it in) Anyhow..I'd like to know more about the speakers... Wattage-at birth? ( i know to not push an old old speaker) Ohms? Im assuming ok for guitar? plan on building a nice 2x10 cabinet for them basically..what are these things?
