My speedwoofer 10S will be here on Wednesday of next week. I made a great choice with picking this sub-woofer with not only your recommendation but also from RSL and Vanatoo. When i told both companies I was combining the RSL speedwoofer and the Vanatoo transparent zeros they both had extremely positive things to say about the other company. Vanatoo said the RSL speedwoofer 10s transforms the transparent zeros into a full range potent system and it will rock my room. RSL said they loved the vanatoo speakers they tried and said the speed woofer which is a very articulate and musical sub woofer will pair excellent with the Vanatoo zeros. Its really nice to see companies in such a competitive market have such nice things to say about one another.
