I´ve seen a used Glock Heart Core cab for sale. It´s rated at 400W RMS and has a 15"+10" configuration. How loud can one expect to be with such a cab (with a pre/poweramp setup)? Ive used an SWR 2x12 bigfoot in the past and that was loud enough but muddy. And I also tried a EBS 210 alone. That could not handle my lows but was really articulate. I like fat lows but only play 4-strings but my attack is quite hard and that´s why the EBS farted I guess. How would the Glock compare. Also what is one of these in good used shape worth?
