Can you swap the speakers out of an Ampeg 810e for increased power handling and/or better upper mid to high end clarity? The catch - can you do this without going beyond the parameters of what the cab was designed to do along with avoiding phasing issues and what not? If someone has and we can all reasonably agree it's technically ALRIGHT, please let me know what speaker you used. I recently used the Ampeg HPC cab (1500 watt 810) and felt the upper mid to higher treble clarity was muffled. However, the mids were punchy and the lows were great too. This trails off into the next question: looking for an 810 lighter than 165lbs with more wattage capabilities than the Ampeg 810e. (Using a Mesa D800 and a 5 string). Also looking for it to be two separately wired 410's (if possible).
