The Harbeth HL Compact 7 line was launched in 1994 as a successor to their HL Monitor model. In contrary to the HL Monitor, the first HL Compact 7 speaker featured a mid-bass driver with a diaphragm made of a special blend of injection moulded polypropylene, patented by Harbeth and referred to as RADIAL. The first model was produced until 1999, when it was replaced by HL Compact ES-2. This model stayed in production until 2007, when it was in turn replaced by its latest reiteration – HL Compact ES-3.
Harbeth C7ES-3 sits exactly in the middle of Harbeth range in terms of cabinet size. It features an in-house mid-bass 200mm unit, however, as opposed to its predecessors, the diaphragm of this driver is made of RADIAL2 – an upgraded version of RADIAL. The tweeter is a Seas unit, featuring 25mm aluminium diaphragm protected by a fine mesh. The C7ES3, similarly to other Harbeth speakers are designed to sound best in domestic environments at normal listening levels (i.e. 70dB to 90dB). They are optimised for use away from walls and with tweeters at ear level.

Thin Wall Cabinet Design

Harbeth C7ES3 are made of thin MDF walls veneered on both sides. It is a design, based on research conducted by the BBC. All the walls inside are dampened with bitumen pads and front and rear panels are screwed on. This design is supposed to reduce transfer of the resonances between the cabinet panels, reduce their amplitude and tune them to fall way below midband frequencies. The idea being, that regardless of how rigid the enclosure is, it is impossible to completely remove the resonances, thus, it is better to move them to less critical frequencies instead and lower their level.
