I'm curious, why is this a bad plan? Is the 1x15 more likely to blow in this situation?
I was about to start running my rig as a 4x10 and 1x15 but I have the option to run as a 4x10 and 2x10 or 2x10 and 1x15 if either of those option would be safer.
Sorry for the hijack but I figure any information shared would be relevant.
Thanks
Kim

The exact results of mixing are hard to predict, whereas using the same is easy to predict, same as one, but more. At some points in the back and forth movement of different speakers with the same signal they might be moving in different directions due to differences in how they respond to signal, and this shows up as inconsistent sound depending on where you are in relation to them. Additionally they might have different impedance characteristics (the 'ohms' is just a vague nominal figure', impedance is actually variable with frequency), which can put weird loads on your amp and unbalance the power. Simplest situation that can make one of your speakers die is that the happy one is being loud enough that the farting one is drowned out so you don't hear it and turn down.
