3D E S I G N C O N C E P TThe TX line from Mach is a complete series of professional speakers that borrows may designfeatures from the larger Mach speakers. The speakers in the TX line deliver clean, loud, anddynamic sound in a rugged, easy to handle package.Features include a heavy 1.5 mm steel grill with maximum air-to-metal ratio, protective metalcorners and integrated handles. The cabinets are made of high quality MDF that is highlyresistant to humidity and include excellent inner damping for improved clarity.The top-boxes are easily placed in arrays due to their 15° trapezoidal shape. They feature ourcustomized 1" compression driver with a specially designed 90° x 40° horn, which utilizes theWaveShaper technology from the larger Mach models, ensuring excellent dispersion controland clarity. All TX models feature a professional Speakon terminal with link option.For additional sub-bass output, the speakers in the TX line can be supported by the TXS18, areflex loaded subwoofer with stackable corners and integrated high-pass filter. The high-passfilter enables you to operate two subs and top-boxes with one amplifier. When connecting theTX12F or 15F through the high-pass output, the top-box woofer is protected against over-excursion.The TXS18 also features an integrated aluminium top-hat adapter that enables you to place theTX12F or TX15F above the subwoofer with a speaker pole (P/N 93943004).C O N N E C T I O N SAll models in the TX line are connected through the 1+ / 1- pins on the Speakon terminal. Forcorrect polarity, connect the red (+) terminal on the amplifier to 1+ on the speaker. Likewise,connect the black (-) terminal on the amplifier to 1- on the speaker. If one speaker is operatedwith reverse signal polarity, the result is a strong decrease in bass output and lack of focus in themid/high frequencies.When using the high-pass output from the sub-woofer, simply link from the high-pass output onthe sub to the input on the speaker. Pin configuration is stated on the label. Please refer to therecommended amplifier sizes in the specifications on the last page. Do not connect thesubwoofer high-pass output to the amplifier output, as this will cause damage to the amplifier.All models feature a Speakon speaker terminal with link option. This option allows two or morespeakers to be operated in parallel from one amplifier.When using the link output option, be aware that impedance drops with each additional speakerconnected through the link terminal. The impedance is 4 ohm when two TX top-boxes areoperated in parallel and approximately 2.5 ohm when three are operated in parallel. Alwayscheck the recommended minimum load of the amplifier.
