Hello there guys. I'm hoping one of you guys can help since this is your expertise. I'm looking for a really great speaker for a little vintage radio I have. I'm going to gift it to my barber but I want to replace the broken speaker with a really good all around speaker. Currently he owns a Bose radio and I sort of want him to really use the vintage radio when he gets it so I kind of want a great speaker to put in this guy that kind of makes him think twice before turning on the Bose over this guy. Right now I have a FatalPro that I have left from a previous project but it's just too big. I don't want to do any surgery at all to the chasis of the radio and therefore I'm looking for a all-around speaker just as good or better than the FatalPro that I have but that the back end of the speaker is not as big as the picture attached / below. I'm hoping you guys can give some insight. Thanks a bunch in advance.
