It is interesting how similar they look. The Theil uses an 1" aluminum dome tweeter compared to Axiom's 1" titanium dome. The woofer is an 6 1/2" aluminum cone making the basic configuration similar to the M40.
Theil is a high end U.S. speaker manufacturer. Jim Theil is the owner/chief designer similar to how Ian is the proprieter of Axiom. Theil is known for designing and manufacturing their own components including the drivers in house. Reading their literature on this speaker which is a lower end model, I get the feeling this tweeter was not produced in house as are their higher end drivers. It would be interesting to know the source of both the Theil and Axiom drivers.
Theil makes great speakers that sell for a lot more than axiom's. Theil's higher end products feature unusual construction like heavily sculpted solid aluminum or high density composite front baffles. A common feature of Theils is the cabinet/front baffle that slopes back towards the top as a way of acheiving time alignment between the drivers so that the distance from the listener is farther from the higher range drivers.
