The Tweeters were changed from Blue to Black
The Tweeters were changed slightly to remove some of the upper end harshness
The glass tops on the towers was improved
Other than that these were pretty much identical to the Saphire line.
How does this happen?
When a company, in this case Tweeter, no longer manufacturers a speaker, often the overseas factory continues to own the "tool" used to manufacture the product. When this happens they sometimes look for other vendor who may want to pick up the line. Since there is significantly reduced cost, building a tool can cost in the 10's to 100's of thousands of dollars, the new project starts life with a reduced manufacturing cost.
This is how TSC was able to sell high quality speakers at half the price.
More next week on the story of the T series speakers.
