This is the original ACT which established Wilson Benesch in the high end and as a leader in the use of carbon fiber. They are a two and one-half way configuration with 89dB/watt sensitivity. The enclosure is a combination of solid wood (cherry I think) and carbon fiber. I have the original cardboard boxes, carpet spikes and owners manual. I have enjoyed these speakers for more than ten years, but due to down sizing they need to find a new home. Although I have the cardboard boxes, I do not consider them adequate for shipping by the usual suspects. The speakers are located in Sonoma County. Local pickup preferred, however I will deliver within Northern California or meet someone from Southern California half way. Questions please ask.
