For what its worth I do not think Martin Logan planned on the Spires being so good at their first design onset. With that being said they may have not been selling as many of them as they thought they should to re coup. Remember there is a second driver and such in them. More cost to build less profit than the Spire maybe.
Having not heard the Spire the Summit still is the best Hybrid I have heard.
