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- ).
