I've used an EVS stepped attenuator with McIntosh MC30's driving Maggie SMG/A's and loved them. Not a 'rocking' setup, but for anything short of metal it was a great sound and I never had any trouble getting plenty of level from it despite being passive.
The Maggies are softer and lighter in the bass than most box speakers, so it might be a bit apples and oranges, but I'd give it a try if the home trial is available.
