OWNER’S MANUAL
Configuration
The TL-1121 subwoofer comes with dual 2 ohm voice coils. This enables the user/installer
to connect one TL-1121 subwoofer to an amplifier in either of the following two ways:
1.
Parallel – Recommended (See fig. 1 below).
- Connect the negative terminal of the amplifier to both the negative terminals of the
subwoofer.
- Connect the positive terminal of the amplifier to both positive terminals of the
subwoofer.
Connecting the TL-1121 2 ohm voice coils in parallel like this gives a load of 1 ohm to
the amplifier. The maximum output of the amplifier at 1 ohm should be around
3,000w max and 1,000w RMS but no more. The Competition Pro TL-1023 Class D
Monoblock Subwoofer Amplifier (3,000w max and 1,000w RMS @ 1 ohm) is strongly
recommended.
2.
Series – Not Recommended (See fig. 2 below).
- Connect the negative terminal of the amplifier to the negative terminal of one of the
voice coils (left one for example).
- Connect the positive terminal of that voice coil (left) to the negative terminal of the
other voice coil (right).
- Connect the positive terminal of the amplifier to the positive terminal of that voice
coil (right).
Connecting the TL-1121 2 ohm voice coils in series like this gives a load of 4 ohm to
the amplifier. This is not normally favourable as the parallel configuration gives a
lower load impedance, getting more from the amplifier.
If mounting the woofer outside the enclosure, pointing in, the connections will be made
straight to the amplifier. If mounting the woofer inside the enclosure, the connections will
be made via the terminal block on the side of the subwoofer box. The Competition Pro TL-
1120 enclosure is recommended, as it has been manufactured to match the TL-1121 and
allow the woofer to perform to its full potential.

Technology
The TL-1121 subwoofer boasts extraordinarily high cone excursion with extreme linearity
and a simultaneous super-efficient heat discharge system. An overview of some of the
innovative, cutting edge patent pending theloudest.com technology implemented in this
subwoofer is as follows:
·
Symmetrical Magnetic Drive (SMD).
Focuses on a unique piston technique that generates immense momentum drive, far
greater than conventional designs.
·
Direct coupling advanced layer bonding (DECAL).
Generates superior strength magnetic flux from the magnet to the voice coils, relentlessly
delivering huge amounts of power. A specially extended top plate layer draws and directs
the optimum strength of magnetic flux from the magnet to the voice coil. Subsequently,
the internal pole piece draws and concentrates the flux from across the air gap to the back
plate, as a result, depositing immense flux in the lower air gap plate.
There are three layers that make up the complete DECAL structure, each possesses a high
permeability of magnetic flux. The upper and lower layers double up as efficient heat
dispersers as well as generating flux. The thicker centre layer is where magnetic energy
flow is maximised.
·
Airborne Heat Relief System (AHERS).
Efficiently transfers and dissipates heat to the outer massive heat-sink. This allows the
voice coils to consume more heat energy and to ultimately reproduce more power.
As the predominant force resulting from the symmetry pushes the woofer up, further
momentum is gained at the lower air gap plate in driving the cone back down to its original
position. When driven like this to full potential, in conventional woofers, the output is
quickly capped as the woofer is strangled by accumulated heat in the air gap and voice coils.
In the TL-1121 though, the DECAL and AHERS systems ensure that this doesn’t happen.
Heat is efficiently dispersed out through the upper and lower DECAL layers to the massive
outer heat sink chassis fast enough to allow more current to pass through the coils again.
The AHERS allows more cool air to replace the warm air through the entire vented pole
piece. These two systems alone enable the woofer to consume extraordinarily higher
amounts of current, therefore allowing the woofer to perform to uncompromisingly high SPL
levels.
