Graham Audio LS5/5 speaker

The LS5/5 is a large three way monitor featuring a slotted front baffle. This unusual feature works to control the off axis response of the drive units, which results in a smoother response through the crossover regions.

A 12″ drive unit handles the low frequencies up to 400 Hz. At this point, an 8″ midrange takes over before handing over to the 1″ soft dome tweeter at 3.5 kHz. Overall, the frequency response is flat to within ±2 dB from 40 Hz to 20 kHz.

Straight away you will notice that the bass and midrange drivers are mounted behind slots on the front panel. This feature is highly unusual today, but it works to control the off axis response of the drive units which results in a smoother response through the crossover regions in typical listening environments.

Naturally, this is a BBC-style “thinwall” cabinet, where the relatively thin panels are mass-loaded to ensure that resonances are moved away from the critical mid-range region. Rockwool provides air damping. Hand-matched veneers are applied and finished to a very high standard. The grille is carefully designed to minimise diffraction effects and is held in place by concealed rare-earth magnets.
