With 90dB sensitivity and a nominal impedance of 8 ohms, the speakers are easily driven by any good quality amplifier. Various locations for positioning the speaker in the listening room are catered for by providing a foam bung which can be inserted in the rear-mounted reflex port modifying the bass response to suit positioning against a rear wall or close to a corner.

The elegant tripod stand allows the Concept 40 to achieve perfect rigidity and floor contact, which further enhances its performance. Even the speaker's attractive brushed aluminium facia plate is not purely decorative. It's part of an assembly, which clamps a butyl rubber sheet to the front panel to reduce cabinet resonance still further in the panel facing the listener.
