A little while ago I posted a thread titled "My 15 Can't Handle It." I got a LOT of good info from some very knowledgeable people, however my problem has yet to be solved. A quick rundown: 1. I set up my semi-parametric eq according to my taste (and I know what I'm doing). 2. My tone is causing excess excursion (cone movement) in my 15 inch Son of Bertha at somewhat high volumes (though not at gigging volume), thus giving me a limited volume at which I can play. 3. I went back and re-did my tone from scratch...all flat and guess what? After cutting and boosting for a very long time I came up with the exact settings. Changing my tone is not an option. 4. The compressor with ratio adjustment cuts out my punch. It doesn't sound nearly as dull as a limiter, but I still lose the punch. My current setup is a Spector NS2000 4 string plugged into a Mesa Boogie M-Pulse 360 which is running an SWR Son of Bertha and Goliath III in unison at 4 ohms. I don't want to run at 2 ohms. Also, sometime in the future I will complete my Warmoth 5 string so I'm hoping I can get ready with my amp/cab setup now. My options are I can get an 18 (SWR Big Ben 400 watts, 25hz), get a 15 that is tuned differently (my current 15 is tuned to 45hz and my 410 to 40hz), or just get lots more speaker/surface area. All that said, here comes the big question: What's out there than can deliver at the volume I want without compromising my tone (something close to SWR)?
