The Mackie SRM450 version 2 delivers live sound that sounds like it should. With the SRM Series Portable Active Loudspeakers, Mackie include the technology to help you focus completely on your performance instead of being distracted by constant EQ and level tweaks.

Many portable loudspeakers produce lows that lack substance but the SRM450 V2 delivers astonishingly deep and defined bass frequencies, outperforming the original SRM450, which was renowned for its ability to deliver real low-down sound. That’s thanks to the SRM450 V2’s Servo Feedback technology combined with its all-new neodymium woofer and 3-inch voice coil.

The SRM450 V2 employs reliable protection circuitry, a built-in limiter for less distortion at peak levels, and an automatic sliding high pass filter to give you that little bit extra volume when the crowd demands more. Thanks to the advanced technology of its power supply and Class-D amp topology, the SRM450 V2 is greater than 90 percent efficient, so more of the power from your outlet goes straight to the transducer, without the power supply and amp giving off loads of heat. Less heat means better performance, and longer life.

Based on the amplification concept of the successful FIFTY LINE system, the FORTY LINE system offers high sound pressure levels with professional audio quality. Compact cabinet measurements, and lightweight enclosures, make the FORTY LINE the perfect choice for professional public address systems.

Useful for most sophisticated applications, the FORTY LINE is easy to handle, small in size and totally portable. The basic set consists of two QL15 active subwoofers and two passive QL12 tops. The QL15 subwoofer is a solid bass-reflex subwoofer with a highly stressable 15″ woofer with a 3″ voice coil. The 3-channel amplifier, which is integrated in the QL15, provides 500watt/RMS for the internal 15″ and 200+400 watt/RMS for the top unit.

A digital processor, which handles the active frequency crossover, also has an integrated time and phase correction unit, active EQ unit, and extensive protective circuitry, which ensures perfect sound reproduction and the safe operation of the power amplifier stages at all times. The QL12 top uses a 12″ mid woofer and a 1″ driver with a pure titanium diaphragm.
All speaker components are designed by dBTechnologies and are produced under the highest quality criteria. The specially designed HF-horn offers a wide and clear dispersion (90°x60°). As a result of these selective measurements utilizing high-class components and superior assembly processes, together with active separation and delay adjustment, the QL12 top reaches a sound pressure level of up to 128dB of crystal clear sound. A high frequency boost switch is incorporated to adapt the high frequencies to a particular acoustical environment when required.

If additional Bass SPL is required, for example during open-air performances, the basic FORTY LINE System may be extended by two QL 152 subwoofers. Due to its multi-chamber band-pass construction and the two efficient 15″ woofers, the QL152 subwoofer, which is powered by the integrated 800watt/RMS Class-H amplifier, supplies an incredible 134dB, ranging from 40-90 Hz. All amplifiers of the FORTY LINE system are equipped with powercon mains connectors with loop through. The internal temperature controlled fan and all amplifiers are protected by a dust filter. The enclosures are made of multiplex, coated with a robust lacquer in Cobalt Blue. The subwoofer features mounting points for a trolley, and the top features a flange for a stand and three M10 threaded fly points. Due to their optimized position, the threaded fly points automatically offer an inclination of 20°.

The QL15 subwoofer has a compartment built in to accommodate the mains cable and the 4-core speaker cable to connect to the QL12 top unit. Mains cable and the interconnecting cable for the QL12 are included with the QL15.

If additional Bass SPL is required, for example during open-air performances, the basic FORTY LINE System may be enlarged with the addition of 2 QL 152 subwoofers

Given the fact that the frequency response of the QL15 is reduced to the frequency range of 90 – 200 Hz, not only is the bass sound reflection much more powerful, the low mids profit too! Due to its multi-chamber band-pass construction and the 2 efficient 15″ woofers, the QL152 subwoofer, which is powered by the integrated 800watt/RMS Class-H amplifier, supplies an incredible 134dB in the frequency range of 40-90 Hz.
