Is there any noticable difference? The amp at my school has a horn that sounds like ****. I always just turn it off. I'm building a cab- If I leave out a tweeter it will recquire no crossover- correct? I looked inside my Sunn 215 cab and the wires just ran straight from the jacks to the speakers. Does this simplicity have a downside-will an added horn give me more than harsh string noise?
