I would like some opinions. I am about to buy a bass amp. It is either going to be Behringer BX4500H Ultrabass Bass Amplifier Head (450 Watts) or the Hartke HA2500 (250 watts). Both would $250.00. which would be the better amp? I would be running it through a Hartke 210xl(eventually 2 x 210xl's). Any input would be appreciated.
