MartinLogan Motion 4 vs Gallo A'Diva

I have a fancy system and all that, but sometimes just want to listen to the news and that's an awful lot of power to draw from the wall just to casually watch nonsense TV or news type stuff.

My plasma has 6-8 ohm speaker outs, so I'd like to add some kind of super-small speaker at low cost. I've been running, in this form, some old cambridge soundworks and they have been fine, but are 15+ years old and the high end is super-tinny, basically unlistenable.

So I am wondering, I know this is lower-end than most of what goes on here, but I'd like to spend not more than these cost and am open to other models, but can't be more expensive or larger.

What do people think? I slightly lean towards the A'Diva at this point, but am not 100% sure.

This might actually be a common use-case, so maybe lots of you have thought about simple computer/tv speakers for non-super-high-end use. Note that several computer speakers don't quite go loud enough for this application - many of those are optimized for a 2- 4 foot listening distance.
