Guys, I'd like to get a somewhat portable system for driving a pair of Aurasound 50w 4ohm bass shakers, aka tactile transducers. I already have a big, heavy Crown amp but I'd like to go smaller and lighter. Before I waste time and money I'd like to know if a class D bass amp, such as the Trace Elliot Elf, could do the job? I'm wondering just how well it could handle it since the caps aren't that big so repetitive shaker "hits" might not be possible. I don't want cheap Ebay amps. I need something better built, which is why I thought maybe these small class D bass amp heads might do the trick. Any thoughts or suggestions appreciated. Thanks.
