"The Wave Guide Orca Speaker is a historic take on the Orca design. Historic meaning simply that older speaker designs often have a screw on back panel to give access to the driver which is attached to the inside of the front panel. The result is a short wave guide (like a tiny horn) in front of the driver which gives older speakers their characteristic sound. The significant price difference compared to the surface mount Orcas is due to the increased difficulty of machining the parts and increased final assembly time of a speaker a screw on back panel.
The WG Orcas provide a similar, yet slightly brighter upper midrange yet slightly softer high frequencies than the surface mount Orcas or Marlins. For many folks the WG Orca model is ideal for unlocking the lowest listening levels because the frequency response overlaps with the Fletcher Munson curve of the ear at low volume levels."
These new Orcas will also incorporate what Clark calls "tuned thickness" cabinets.
