Over the past 5-10 years, I'm starting to see compression drivers that are (finally) pushing the performance envelope. Up until 2009 or so, you basically had two options: 1) a lot of compression drivers that can cover four octaves that cost about $150 2) a handful of beryllium compression drivers that can cover 4.5 octaves that cost about $1000 We're *finally* seeing some affordable compression drivers that can do 4.5 octaves, such as the Eminence N314T that's pictured above. That IS compelling for a Unity horn, something similar to the SPL RUNT: an 8" woofer combined with a single compression driver. The original "RUNT" used a BMS 4550, and as I understand it, was one of the reasons that BMS became ubiquitous with the DSL speakers.
