K2 Slimline (approx. 1964-66)

The K2 Slimline used the Celeste/Duette drivers (B139 and T15) in the same enclosure as the K1 slimline, allowing a compact speaker with a depth of only 6.75 inches (170mm).
 
To minimise tonal colourations the enclosure was substantially braced with the panels damped with bituminous pads, and finished in Walnut with a coffee fleck grille.
