SYSTEM REQUIREMENTS
TXD series enclosures (with the exception of the TXD-252 and TXD-15M) are passive loudspeaker
systems. This means that they require only one amplifier channel for correct operation, the
frequency splitting between the low frequency driver and the high frequency driver or mid and
high frequency driver being accomplished by the internal passive crossover network built into
each enclosure.
If low frequency enclosures are used to extend low frequency response, this can be achieved
without the need for additional amplifier channels or external electronic crossovers. TXD series
low frequency enclosures are equipped with internal low pass crossover networks which filter mid
and high frequencies away from the bass speaker. Therefore a full range system consisting of, for
example, two TXD-121 and two TXD-115 can be powered from a single amplifier as shown below,
thereby saving the expense of additional amplifiers and external crossovers.

Connect the amplifier output to the Speakon INPUT socket on the bass enclosure.
Then connect an additional speaker cable from the LINK socket on the bass cabinet to the INPUT
socket on the full range cabinet. Speakon pin connections are shown below.
