Adding the s8 was a revelation. The build quality is near perfect, there's no lose parts, and the knobs feel smooth. Only con is that it is a bit pricey.

Sound is terrific and well-integrated. I have these paired with a5+ and sound amazing. Easily the heaviest unit of my speaker setup. Delivers clear yet powerful sound from the n22 amp.

Wow, this little subwoofer really cranks out the bass. Produces excellent rock such as zep, floyd and steely dan for example. Stand up bass.

The sound that comes from this 8-inch sub is impressive. My recommendation when purchasing this sub is to play with the crossover and volume.
