Further improvements have been made again with the cabinet, bass driver and crossover network.

The cabinet on the D18 is very heavily damped with a new material; it is also now side vented as other high-end models in the ProAc range. A new high tech bass driver is similar to the D2, it however has a larger EXCEL magnet assembly and an acrylic damping phase plug.

The results of these combination of improvements are a deep beautifully controlled bass response, a fast electrostatic midrange with a sweet and detailed high frequency.
