Just curious at this point, but take a look at my rig picture and spec's from my post here (#96).
When I bought my amps I was on a tight budget and I didn't mind that they come in under the power rating of the BE cabs. But down the road I may want to get something that can really wake the BE's up.
I've read that BE cabs can take much more than their specified power rating. I'm just wondering, from those with experience with BE cabs, how much they can really take consistently? Both cabs are rated at 400w.
Are you running at 2.67 ohms? (one 4 ohm + one 8 ohm cab) You will need an amp that will do a 2 ohm load or at least 2.67 to be exact. Remember also that the 4 ohm cab will get twice the power of the 8 ohm cab when considering this. This is what BE has to say about the subject. I would sum it up as yes, you can run them with a high-powered amp (I do) but you must be judicious and smart about it. Listen to the speakers and do not drive them to distortion for extended periods.

"Recommended amplifier size: Amplifiers will vary greatly from different manufacturers. The amplifiers output power rating is only one part of the information required to chose an amplifier for your system. Different amplifiers with the same output power rating will sound different and have various feelings of power and fidelity. Added to this are the various playing styles and techniques of the individual musician which will utilize various degrees of dynamic range. With a playing style utilizing wide dynamic range you may successfully choose the higher power rating, while a hard driving rock style would be safer choosing the lower power rating and adding additional speakers as required for a high output system. A system limiter is always a good choice to prevent the power amplifier from clipping which can both sound bad and cause speaker damage."
