I've been thinking about getting an Avatar Neo 410, but I can't decide between 8 or 4 ohms. I will be using it with a Genz Benz Shuttle 6.0, and was wondering whether the cabinet would really be any louder with the 600 watts at 4 ohms compared to 375 watts at 8 ohms. I recently discovered thermal vs mechanical power handling and even though I don't know enough about it to probably make a correct mathematical guess, I still wonder if the extra 225 watts would be overkill/useless for the cab. My other though was that if I really needed to, I could always add an extra 8 ohm cab for large shows or outdoor gigs. Any thoughts from anyone with this experience? Dave at Avatar kinda gave me the "everyone else does it, so you should be fine" answer, which didn't really answer my question. Thanks.
