A couple of years ago, I picked up an Eden 210XST (4Ohms). I had an Ampeg SVT-III Pro at the time and now run a Little Mark II. I LOVE this cab. So loud and so good. Love the sound with either head and had no problem when I was running my old 1992 Ibanez SR506 (Iba) through the set up. Sounded great. Just picked up a mid-90's MIM P-bass (Patricia) and it sounds great all night long. My problem is that my Active Warwick Corvette Standard 5-string (Woobie) sometimes causes the head to drop in volume, periodically through the night. Now, Woobie is a hot bass, it's almost twice as loud as Iba, so I'm thinking the problem is that the signal causes the speakers to "stick". It's like the speakers intentionally cut their movement significantly so as not to blow. Does this sound right? If it's not the speaker, then it must be the bass and I'll start looking there. Thanks for any input and thanks for reading through all of that!
