Alright I just bought a pre us music eden 115xlt cab. This is my first real rig and maybe im just not doing something right. Im running a Hartke Ha2000 head into this cab, and at lower volumes the cab sounds great, but at louder volumes say volume on 5 the speaker farts out on my low b. Im playing a cort a5, those of you not familiar with it, it has bartolini mk1 pickups and active 3band eq. This cab is 8ohms and supposed to handle 400watts. At 8 ohms the hartke head is only supposed to put out 125 watts. Any help or suggestions would be much appreciated, and if I need to answer any questions please let me know Thanks guys!
