#126 Tannoy System 600: $400 per pair Discontinued eBay
Pros: Impedance is well controlled, and the concentric dual-driver layout gives it consistent horizontal and vertical response relative to typical non-coaxial 2-ways of its era.
Cons: CEA2034 spinorama shows a large suck-out right at the crossover frequency where the two drivers fail to overlap properly, plus general peaking beforehand - the reviewer noted “no measurement seems to have been used to optimize this design.” Predicted in-room response is correspondingly poor. Amir ran out of time to perform a dedicated subjective listening test on this unit, but concluded from the data alone that it is “highly colored and really not something you want to put in your system.” Long discontinued; used-market only. Discontinued.
