I've got the A5 model for my TV. For TV use in most rooms I think you'll definitely need the 5 instead of the 2, which is just too small, sorry to say - more bass, more room filling sound. Yes they're larger and more noticeable but the difference is well worth it.
I've got my 5s on small speaker stands in front of the TV and feel I'm getting real audiophile sound from the 5s, even from cable.
