It's funny that it is called a Workingman 15. That's where I'm having an issue. actually hearing the name was enough to have me grab one. Replacing a 18" cab, 4x10 cab and SVT head with a 60lb 15"combo with horn seemed great for my rock band. We have a controlled drummer and 30watt tube guitar amps. So I figured I'd be heard. At practice the amp is about at it's limit. Live, I'm bumping the clip and limiter constantly. And I do not at all have a crazy good bottom like I want from a 15. What I do like is how it sound to practice or record. Very clear and uncoloring. Quite nice. Works great for acoustic guitar too. Great to use in practice and not run down the $$$ gear. A feature of the combo is the ability to drive another cab and raise the watts from 120 to 160. I can bring an 18 with me, but i might as well bring the big rig. SO there is a limiter disabling feature I'm scared to use for fear of blowing the speaker. I'm assuming that would allow for the full 160W? Is my answer that simple... Would a new speaker give me the bottom and the protection against, I assume 160W with the limiter disabled?
