TSB–110 CONFIGURATIONS
The TSB-110 is a general purpose band-pass subwoofer designed to add low frequency
reinforcement to Turbosound loudspeakers such as the IMPACT50, IMPACT80, TCS-30, TCS-35,
TXD-081 and TQ-308.
The TSB-110 utilises a dual voice-coil 10” low frequency driver with two configurable 4 ohm voice
coils. In its ‘as shipped’ configuration the two inputs and two outputs are set up so that the bass
cabinet can be driven by the left and right channel of a standard two channel (stereo) power
amplifier. The input connections are labelled left and right on the spring terminals and are also
present at the 1+, 1- (left) and 2+, 2- (right) connections on the Speakon NL4MP socket. Outputs are
available through the spring terminals only.
The inputs drive the two voice coils separately via a 150hz low-pass first order filter. The satellite
speaker outputs are provided via a high-pass first order filter at 150Hz.
Amplifier considerations
Turbosound speaker enclosures should be driven by high quality power amplifiers designed for
true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and
well designed cooling systems for reliability. Turbosound power amplifiers such as the T-45 and T-
25 are recommended for this purpose.
The program power listed in the loudspeaker’s technical specification is the best guide to the size
of amplifier required for general purpose applications. The amplifier should therefore be capable
of delivering long term broadband power equal to the loudspeaker’s program power rating at the
loudspeaker’s stated nominal impedance. This approach allows sufficient headroom to generate
good dynamic range.
In general, the more powerful the amplifier, the better it will sound, provided that it is not driven
into sustained clipping. It should be understood that overdriving an insufficiently powered
amplifier is more likely to cause loudspeaker damage – the total energy in a heavily clipped signal
is far higher than in an unclipped signal – than operating a more powerful amplifier within its
ratings.
RECOMMENDED AMPLIFIER POWER RATINGS:
The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, each
channel) should be 2 x 300 watts at 4 ohms per channel.
Single coil (8 ohm) configuration
The TSB-110 can be configured as a single 8 ohm sub-bass unit if required by effectively patching
the two voice coils in series. To do this, remove the connector dish housing the spring terminals
by removing the six cross-head fixing screws and lifting it out and away from the cabinet as far as
the internal wiring will allow.
