I've just made a deal to trade my bass guitar roadbox with two JBL K140 15" speakers for a single Altec 15 Series II speaker enclosure in order to get something smaller that will fit in my import car. The fellow who's trading the Altec 15 Series II just messaged me and says he's not sure if the speaker is designed for bass. He says he tested it with his bass and there's a lot of high frequency content, but he says it sounds great with his guitar. I was under the impression when I arranged the trade that the Altec 15 Series II were bass speakers, but I'm wondering now if that series also included guitar speakers. I'm unable to get any additional information, so I'm hoping you can tell me if what I'm trading into is a bass speaker. Thanks in advance for any information you can offer.
