The edges of the cabinet's baffle should be slanted or rounded.
Should the cabinet be positioned against a wall, the bass reflex tube may also be mounted beneath the bass driver (below bracing panel) pointing forward; in this case the tube should not be shortened.
The recess depth for the tweeter should be 3 mm or 6 mm, in which case 2 layers of sealing tape or 3 mm cardboard should be used.
The cabinet should be damped with one pack of polyester fleece, to be placed from the centre upwards.
If a valve amp is being used we recommend to adjust the impedance by installing a serial resonant circuit with the following components: - 12-Ohm resistor MOX 10 (brown-black-black), - 0,82 mH air-core coil, 0,7 mm - 15 uF electrolytic capacitor, smooth All components need to be connected in series, the two ends will be connected to the loudspeaker terminals.
