Landmarks in speaker design have been few and far between. There are a few certain contenders: in the UK, the original Quad Electrostatic and the ESL-63 qualify, while the Celestion SL600 scored a big point for all small monitors; the Spendor BC1 changed forever the notion that cone speakers were always colored and that big boxes were essential for good sound. In the States, Apogee has taught us much with their surprising mid-treble ribbon-based designs. Other technologies have shown promise but have not achieved real commercial success.
