The Revelator 18W series of drivers continue the enviable trend set by the smaller 15W versions. There's a few variants and different impedances - they are all excellent. This version is available in 4 and 8 Ohms. A full datasheet is available for download at the bottom of this page.
Popular among high end & esoteric designers - and with very good reason.
Featuring a unique cone that is precision sliced then re-bonded with damping glue; this procedure gives a very high level of internal damping and control that is not normally obtainable with a standard type cone.
These no compromise drive units offer superlative sound quality with outstanding midrange resolution and solid bass extension.
