Please share your comments... I'm interested in running a 1-15XLT with a 2-10XLT. I'd run them with a GK 1001rb, both cabs at 8 ohms each. The 15" cab is rated at 400w with sensitivity at 100db; the 10"s are rated at 350w and 104db. I noticed that there's a slight difference in wattage rating and sensitivity. Will this adversely affect using the two cabs together? Since the 15 cab isn't as efficient (power-wise) and has a lower sensitivity than the 10s, will the 15 cab run at a lower volume?
