What's your budget?  At every pro audio trade show, I walk around with my 
2m/440 talkie, seeing what mischief I can cause in the gear on display on 
the floor. So far, I've never seen ANY loudspeaker with a built-in amp 
that didn't' detect VHF/UHF RF. That's the bad news. 

The good news is that while the Mackie HR824's will run their woofers to 
their limits on a 2W 2m talkie across a small room, they've given me NO 
grief at all with 1kW on HF, even in Chicago where one antenna was a long 
wire running a few feet from them. YMMV. They're great sounding 
loudspeakers -- or at least they were, before corporate acquisitions 
changed a lot of things. Maybe they still are.
