The HL10A is made for horns so it can handle the pressure. No offense, but I don't
think the Beta 10 would be any good at all. No power handling and a thin cone that can
rip real easy, so it easy to burn and rip. I think its good for a full range monitor speaker
but not for a bass horn, IMHO.Can your horns use TAD 1102, Adire Brahma 10 or even a Dayton Titanic MK3?
They are expensive, but you get what you pay for. Use the HL10A for budget models.
