Ok...I bought a pair of huge Karlson speakers. I know they were designed for one driver, but someone put a 12" bass driver in these. No complaints with bass, so I added a pair of stand-alone bullet tweeters. Whoa....sounds far better, but no mids to be heard. Okay, I need to add some sort of midrange driver, and was thinking about mounting some sort of vintage-ish horns on top of the cabinets. What do you guys think? I'm open to any and all ideas....and, if the horn-on-top idea sounds okay, please suggest some horns that might work (cheaper the better). Thanks!
