SUB 18 and SUB 28

The vented SUB 18 and SUB 28 direct radiators have been designed for subwoofer use in active multiway systems. The superior transient response of the classic bass reflex construc- tion is also well suited for medium to large bass arrays.

The premium 700W RMS long excursion woofers feature extre- mely low THD, and the reliable, all-electronic Voice Coil Tracking Protection prevents thermal overload of the 100mm sandwich voice coils.

For maximum dynamics, the SUB models can be driven by extremely powerful amplifiers; thermal overload triggers a vir- tually inaudible 'soft' power reduction. The 18mm multiply birch wood enclosures feature a rugged two-pot structured finish.

The woofers are damage and weather protected by a sturdy powder-coated steel grille lined with high quality acoustic foam. Wheel kits with four 100mm factory assembled 'Blue Wheels' are optionally available. These are mounted to the back to provide easy and convenient transport .

The SUB 28 is switchable from 1 x 4 ohms to 2 x 8 ohms mode where woofer A is connected to the Speakon pins 1+/1- and B to pins 2+/2-.

When driven by DYNACORD CL, LX or Power-H series ampli- fiers a single 4-conductor loudspeaker cable is required to feed both woofers from amplifier channel A (channel B out- put is also present at channel A pins 2+/2- ).
