[QUOTE="Shonver, post: 761625, member: 34"] Driver size groupings are only rough guides. When it comes to acoustics, the size parameters that matter are radiating surface area (Sd) and cone excursion (Xmax). Related to Sd, a driver's effective diameter can be roughly determined as described in the previous post. There is nothing to debate. Simply read the data sheet for the respective model. It should tell you everything you need to know. Typically, good drivers have well-written data sheets; the ones not worth bothering with don't. Some examples: [url=http://www.tb-speaker.com/uploads/files/33c889df7418fe23abd60ef0245a932c.pdf]http://www.tb-speaker.com/uploads/files/33c889df7418fe23abd60ef0245a932c.pdf[/url] [url=http://www.seas.no/images/stories/excel/pdfdataheet/e0015_w15cy001_datasheet.pdf]http://www.seas.no/images/stories/excel/pdfdataheet/e0015_w15cy001_datasheet.pdf[/url] [url=http://www.scan-speak.dk/datasheet/pdf/22w-8851t00.pdf]http://www.scan-speak.dk/datasheet/pdf/22w-8851t00.pdf[/url] [/QUOTE]
