Peavey 1820 (two 10's and an 18). I gigged with this for years, but I had some issues with blowing the 18" Black Widow. After replacing the cone/voice coil several times, I went looking for an 18" that I could not blow and found a Madison Executioner (rated at 1,000w RMS!!!). I did not know what to expect, but dear lord does this driver kick booty in the 1820! It has seismic lows (the deepest of ANY cab I own!), and it feels like it is actually compressing the air in our practice room! Tone is really good, too. So, with good results here, I decided to try replacing the 10's as well, and based upon the box volume and the frequency response of the 18, I picked up two very nice Selenium 10's (forget the model). Again, a notable improvement, with better articulation and detail (and of course, higher power handling - though I never did blow the 10" Scorpions). I'd sell this cab, local pickup, for $225 with the Madison/Selenium drivers, or $175 if I pull the Seleniums and put the Scorps back in. I have two grills for this cab. The standard one, and one made from metal (in black) to match the Peavey 210TX that I used with this cab for years. It's somewhat beat up cosmetically, but in sound condition. I have some really nice casters that were on it for years (but which I removed to make an amp cart). I could be persuaded to put these back on for a nominal fee (or throw some cheaper casters on for even less!). Tom.
