I am going to the Tucson hamfest this Sat. and a friend back home in Ct. asked me to look for a speaker for his Halli. SX-115. However I don't know what speaker is correct for that receiver. He said the one without the red in the emblem. Do any of you Halli. people have a little better I.D. than that? Maybe a number? Thanks in advance. 73 Bob W1GTH
