The Point Source Reference

These two exceptional drivers are first placed in a coaxial relationship, then time compensation adjusted in a true concentric design. So all the music arrives at your ears simultaneously, not unlike the natural phenomena of sound.

Both drivers are now phase coherent and time coherent. They now produce a point source reference so clean and well defind that the experience approaches the theoretic ideal of a pulsating sphere. It's hard to imagine another close field monitor coming anyhwere near the overall performance of the Fostex RM. Harder still would be to find one with uniform frequency response in both 2 TT and 4 TT environments.

Most small reference monitors like the 765 and 780 are designed for rack, wall or soffit mountins (2TT).

Unlike the others ours have a switch for free field or console mounting (4 TT).

Regardless of the placement, the Fostex 765s and 780s may be switched (front panel, of course) for proper response. And because they are phase and time coherent, you can mount them vertically or horizontally. Rack adaptors and mounting hardware are available, and all holes have been pre-drilled for convenient interface with any standard rack. The problems of placement have been anticipated so that you can get on with using them.

The typical placement of speakers in the typical room results in a confusion of sound. You end up hearing a lot of the room colorations and reflections mixed in with the direct source. Sure, you can spend even more money and equalize the room. Even then you may have to invest in an outboard crossover in order to compensate for the loudspeakers design.

Avoid all these problems with Fostex Near-Field Monitors. They are Point Source, coaxial speakers. A,, the sound emanates from a point reference, just like in nature, so all the sound reaches your ears at the same time. Stereo imaging is rock solid.

This design produces a "sweet spot" so you know that what you're hearing from the RM Series will sound proportionally the same in a car, on a hi-fi system or through a custom-tuned playback system in the studio.

An unusually low crossover point gives you another imoprtant benefit not found in conventional designs: vital midband information like vocals will not be modulated by high impact low frequency sounds like kick drums.

The same RP patented driver gives you uniformly flat high frequency response in all three models; the woofers increase from 6,5 inches to 8 inches to 10 inches. The two drivers in the RM 765 are the identical elements in the RM 865 3-way system, which simply adds a 10-inch woofwr.

This larger system is also ready for biamplification. In our listening tests with 800W -1000W per side, these beauties have generated 116 dB SPL at the console with no audible distortion. The Near-Field Monitors from Fostex give you clarity and punch and definition - as loud as you need it.
