I own an old mid 80s Hartke 410 XL cabinet. I like the way it sounds and it has become a part of my tone. I however hate how much it weighs. Currently I am running my rig in a bi-amp configuration with a 215 on the bottom and the 410 on top. Honestly it's probably too much cab for the high pass: I was thinking of having two 210 cabs built and loading the Hartke drivers into them. I got a pretty good price from LDS. Is this crazy? Should I just drop $200 on a used Hartke 210? Has anyone ever popped out those older Hartke speakers and used them in something else?
