Horn woofer cab for bass guitar on stage did not work well! - Nicoro 13:57:21 06/29/25 (3)
Pre PA/monitor days got stuck with playing bass in the band and figure I try a bass horn cab instead of the usual direct radiating speaker bass amp. The musicians on stage complained they could not hear enough bass while the public was getting bombed with XS bass!! Even horn bass cabs have some directionality?

  What you experienced was cancellations close to the cab from boundary reflections. Further out the boundary reflections weren't causing cancellations as the distances between the cab, the boundaries and the listeners were longer. It had nothing to do with horn versus direct radiator. You don't get directionality until the size of the radiating plane is a wavelength. With a direct radiator that plane is the baffle, with a horn it's the horn mouth. I've used horns exclusively playing bass for the last 30 years with no issues.

    Yes Bill cab was close to the side of the stage not center likely boundary effect. But that horn cab was not very practical long not folded but the alternative Ampeg SVT with 100 lb head and 8x10" cab was a bear to carry around. Thank goodness for SS and class D although mostly studio work now days.

      Folded horns aren't practical for electric bass. They used them back in the day because it was the only way to get really loud with short xmax drivers and low power amps. Long straight horns aren't required, mine are not much deeper than direct radiating cabs. This is my 1x12.
