I have a pair of SAMs but they are used exclusively for 2-channel Audio and mostly for acoustical music, jazz, blues, vocals, etc. For these types of content, I find the speakers very satisfying top to bottom, extremely detailed and dynamic. As for their weaknesses, most full orchestral classical music contents sound somewhat congested especially at higher listening volumes and I suspect in an HT application the bass will be inadequate particularly for highly dynamic movie content. If you can successfully integrate the subwoofers with the SAMs, which may require some experimentation, and depending on your room size and acoustics, you should be able to have a great full range sound.
