Unpacking the Loudspeaker
After unpacking the unit, please check carefully for damage. If damage is found, please notify your supplier at once. You, the consignee, must instigate any claim.
Please retain all packaging in case of future return shipment.
System Requirements
TPX122M and TPX152 are passive 2-way loudspeakers, and TPX153 is a passive 3-way loudspeaker, all of which can be driven directly from a single amplier channel
with no controller. For optimum performance or for use with a subwoofer, they require 1 amplier channel and 1 controller channel. The input signal is divided
between the low-frequency and high-frequency drivers internally with a passive crossover.
The TPX118B subwoofer has a full-range input and link through to connect an additional subwoofer. Operation requires 1 amplier channel and 1 controller channel.
Correct controller settings for all model’s operation, with and without subwoofers, can be downloaded from turbosound.com, and are also available as presents for
the LMS series controllers. To avoid wasting amplier power, you should use heavy-duty speaker cable with a minimum wire size of 1.5 mm² (16 AWG), and preferably
2.5 mm² (14 AWG) for longer runs. For extreme cable lengths, be aware of cable impedance and resistive losses. Always observe the correct polarity.
The TPX122M doubles eectively as a wedge monitor.
Amplier Considerations
The TPX series loudspeakers are optimized for use with the Turbosound T series ampliers with the LMS series controllers. A full range of DSP settings to suit any
conguration are provided for download on the Turbosound website. The use of third party amplication and processing is only advised using the matrix of manual
settings as well as the limiter calculator provided on the Turbosound website. The TPX series loudspeaker enclosures should be driven by high quality power ampliers
designed for true professional use. Power ampliers should be capable of delivering long term broadband power equal to half the loudspeaker’s peak power rating at
its stated nominal impedance. The use of underpowered ampliers must be avoided as heavily clipped signals can cause permanent loudspeaker damage. Limiters,
crossovers and equalisation points must be set in accordance with the settings provided on the Turbosound website. This will ensure the optimum sound quality and
long-term reliability as well as protection from damage.
Neutrik speakON* NL4 locking input connector(s) are provided, allowing options for input and link through.
