Sorry Joe, but I'm with Fred on this one, as well. You're speaking from what you believe to be true based on specs you're reading, but it's obvious to me as one who has actually used various speakers on the K3, including the COMSpkr, that you don't have as complete a picture as some of us who have actually tested this.
I love the K3 and wouldn't trade it for another rig, but it's not perfect. It's ability to drive external speakers is one of the examples where it does not excel. Compared to other rigs, it basically sucks . Period. I'm young compared to most of you guys and have no hearing loss and have quite a good reputation amongst my friends for having an ear for what *sounds* good. After trying quite a few different external speakers setups with the K3 and not being happy with the overall volume output, I decided that the K3 was probably too finicky with what it needs for speaker impedance and decided to just go with a set of powered external speakers and be done with it. The COMspkr is so damn loud that it practically blasts me out of my den if I turn it up much. I don't like to use headphones if I don't have to, and with the COMspkr, I rarely need to. Regardless of what you think the specs say, you need to try this for yourself and make an informed decision.
