Sound: Good for the price ... the bass is very deep but is rather imprecise due to the soft vote. But it helps to damp the bass reflex port. The Satellite are just little wide bands ... you can with a well-tuned 2-way system does not compare, of course, but that would at least 6x cost so much too!
Volume: The I find quite remarkable! Significantly more than one would need really! you can also use the space PA ...
Optics: Top
