Tannoy E11 loudspeaker
The Tannoy E11 ($349/pair) is the company's least-expensive model in a wide range of consumer loudspeakers. Tannoy is most often known for its professional models, especially their nearfield, dual-concentric monitors that have become de rigueur on the top of recording consoles. The E11 is a two-way, ported design with a 6.5" woofer and 1" dome tweeter. Both drivers are manufactured by Tannoy, instead of being sourced from a driver manufacturer. The woofer is made from a polyolefin co-polymer, a plastic material with high rigidity and good self-damping properties. To improve power handling and increase sensitivity, the voice-coil is edge-wound on a Kapton former. The surround appears to be made of butyl rubber.

Rapping on the cabinet results in a hollow bonk, rather than a solid thud.
