Hello Talkbass! I'm brand new to your forum, although I've read it for years. I'm trying to find a good replacement for my SWR Workingpro 12. It has been 10 below zero and I hate dragging in my Ampeg set up in for practice, only to wonder if the speakers have warmed up enough not to shatter. The workingpro is a very capable practice amp, but the speaker ripped on the surround. In looking for a suitable replacement, I'm finding nothing beyond mid 40hz for usable low frequency. This is a problem if I want this amp to let my 5 string sing. There will be the limitation of my cab, but I really want a speaker capable of producing true notes. So my question is... Where can a guy get a 12" speaker that goes down to the mid 30hz level? Has anyone tried rocking a subwoofer? Eminence Lab 12 is looking really good to me, but it drops at 1k. Would I miss the gap to my tweeter, or would the super phat lows be worth it? What do you think?
