Looking for some insight. I currently own the older tl606 designed Mesa/boogie diesel 215 cab. I purchased it second hand knowing both original speakers were gone and replaced with eminence legend cb158's. I've noticed that the cab seems a little dull sounding compared to other cabs I own. I'm torn on what I want to do. I've wanted one of these cabs for some time but I've boiled it down to 3 options. leave it alone: I do have other cabs but I feel it wont get used much if I leave it be. Replace the speakers: either with OG EVM 15's or possibly something else (Kappalte?). Lastly sell it: GAS is a hell of a thing and I can never leave anything be. My current top option I feel is to swap the speakers. I fear if I put in the original EVM's that it might be light in the low end. I've read people loading them with eminence Kappalite 3015's but I didn't have great luck with the Bassic I had some time ago. I was running a completely different rig then and it was years ago so my tastes might of changed on the 3015. So I'm torn and ask for your thoughts and input. Any insight will be greatly appreciated.
