Standards change very slowly,. somelimesnever. And that is as it should be, forsta.lda'ds form our basis lor compa.ison.

Now RWO/FOSTEX updates the industrystandard with a new family of monitorsystems.

There is no magic, nor any heretoforeunknown law of physics involved Simply theapplication of rational, consistent, designengineering coupled with the belief that amonitor should impart no characteristic of itsown onto its acoustic performance.

As the low-f requency performance of anymonitor system is ultimately determined bythe characterislics of the moniloringenvironment, the user should only needconcern himself with selecting the monitorsystem appropriate to the size of the intendedinstallation.

The RWO/FOSTEX Laboratory Series featuresthree models. Each is oplimized for a specificlow-f requency culoff, while maintaining auniform standard of performance.

The hallmark of the Laboratory Seriesl\,4onilors is extremely accurate, highef f iciency, time-coherent reproduction. Thisbreath-taking performance is identical frommodel to model, one indistinguishable fromanother in all but the lowest registers.

The High-frequency array used in the Seriesis common to all three models. Only the Low-frequency transducers and enclosures differ.

The LSi3 will become the standard choice foruse in control rooms. A 40 cm LF driver in a250 litre enclosure yields a 30 Hz response.

The LS/2 rs idea for smaii control rooms,mobiles and other nstal alions where spaceis at a premium. This unit has a 45 Hz lowerresponse limit, utilizing a 30 cm LF driver in a76 litre cabinet.

The LS/4 is unrivalled for applications inlarge, worid class, control rooms and studios.

A four-way design, this outstanding systemcontains a 30 cm MF driver and dual 40 cmLF drivers in a 668 litre enclosure, withaccurate performance to an astonishing19 Hz.

The unique highJrequency array consisls ofUHF and HF transducers, critically mountedto obtain coherent time/phase systemresponse and prevent reflections from thecabinet. These techniques result in excellenttransient response and sensational sonicimag ing.

The U H F transducer exhibits superbly smoothresponse to beyond 20 kHz, and anunprecedented 180'dispersion at 15 kHz,a consequence of the unique diffractionhorn design.

The HF transducer features a no-compromiseradial horn, precision milled from solidEurasian teak to rigid specifications. The highdensity of the teak eliminates resonancesf rom the pass-band.

All transducers used in the Laboratory Seriesare proprietary units featuring large, power-ful ALNICO magnets for vanishingly lowdistorlion, combined with edge-wound ribbonvoice coils for high efficiency. The LFdrivers also feature mica coil formers for con-linuous high power ope ration.

Computer-aided design techniques have beenused in the development o{ the optimumconfigurations for each model, yieldingmaximally f lat response down to the desiredlow-f requency cutoff point.

Each cabinet is constructed of high-densityparticle board, heavily braced with kiln-driedCanadian fir, and finished with Eurasian teakveneer and matte black laminate.

High performance and low loss in thecrossover units is guaranteed through the use

of heavy gauge wiring and close tolerancefilm capacitors. The high temperatureporcelain attenualors are calibrated in dB, forconvenience.

T1e Laboratory Series Monitors o{fer rwo tofour times more output (with the crossoverincluded) than old standards, reducing theneed for bi- or tri-amplif ication and increasingthe available headroom in the overallmoniioring system.

All parameters of operation, includingefficiency, distortion and time/phase andamplitude response have been optimized inthe design of the RWO/FOSTEX LaboratorySeries Monitors.

The resu lts are stunning.
