To me, the ELT towers are a bit small - much smaller than one would expect. This could create a problem for some people as it might bring the tweeter height lower than a proper listening level. However, if you have a theater with risers, etc., having a shorter speaker may not be that big of a deal. Then again, the smaller tower might have a better WAF appeal since they are not so monsterous.
With the size aside, I did hear the ELT towers with music, not movies. The sound was quite impressive and only got better when a subwoofer was attached.
