This Bass head - Behringer 450 watt, BX4500H costs only ab0ut $200 at Guitar center. Why is it cheap considering it is 450 watts? Is the sound quality not good?
I'll bite, but you really only have to post it once -- we'll find it.
Behringer stuff is cheap because it is cheaply made. It is, for the most part, lower quality beginner grade bass equipment. Their cabinets handle a lot of wattage, but I've heard more horror stories of the speakers blowing and cabinets dying than I have heard positive testimonials. For me, I'd save my money and buy a better quality product. No need in spending the money now, then turning around and spending it again in 1-2 years.
