replacing blown redline speaker?

So my redline speaker is seemingly cutting in and out. Start up the car, get a small chirp not the double tone of tsr and pop on and then silence. Put it into highway mode and all the x bands start lighting up the rl but no sound. Now every now and then, i can hear a muffled alert sound after it has been alerting for a minute or two. I am wondering if this is a speaker issue or a hardware issue? I called escort but theyre wanting 60 bucks to change it, so im wondering if its possible for me to just solder in a new replacement speaker or is it something within the circuitry that escort needs to fix?
