| An obvious feature of the M1.5 is the extraordinary output from such a compact speaker.
For the first time, a performance exceeding that of many so called "main" monitors is available from a unit of a size suiting even the smallest facility.
With a frequency response from 40Hz to 20kHz, and a
maximum output in excess of 120dB SPL at 1.25m,
the M1.5 is truly exceptional.
Where it is quite normal to employ audio processing
techniques to extract the last drop of performance from a drive unit in an active system, the totally passive M1.5 relies purely on component quality. The secrets behind its performance lie in the new high sensitivity drivers developed exclusively for this model, coupled with a very efficient twin ported cabinet and an impedance corrected crossover
which ensures that the optimum load is presented to the amplifier at all times. Imaging is pin sharp, even in difficult environments, thanks to the directionally controlled tweeters. A trim switch on the rear of the cabinet allows for fine tuning of the mid/high frequency response, further enhancing its use in near and midfield environments with varying acoustical characteristics.
MAIN FEATURES
- Unique linear phase and frequency response.
- Every monitor matched to any other monitor
within ±1.5dB.
- High efficiency soft dome tweeter with
aluminium voice coil.
- Dual 175mm magnesium silicate impregnated
polypropylene (MSP) bass drivers with exceptionally
large 75mm aluminium voice coils, offering dramatic
improvements in power handling, bass response and
distortion figures over conventional systems.
- Gold plated professional binding posts accepting
heavy-gauge speaker cable.
- Heavy internal damping for minimum cabinet
resonance.
- Thermal protection of the tweeter.
APPLICATIONS
The M1.5 is a fairly "punchy" monitor with an
incredible bass response mainly suited to popular
music tracking and mixing, voice and dialog recording,
and as L, C, R monitors in high performance
surround monitoring systems. Mounted either in the
nearfield on top of a console or in midfield just behind the console on suitable stands, it can easily fulfill the majority of monitoring needs. Flush mounting is also an option when careful attention is paid to room design, construction and acoustic treatment.
