NF-1Series

Near Field Studio Monitors PROFESSIONAL

PROFESSIONALMain features

■ Double spidered 16cm (6.5 inch) woofer featuring a newly developed HP diaphragm which delivers a highly transient sound, wide directivity and exact sound imaging with extraordinary low distortion

■ A UDR tangential diaphragm edge eliminates unwanted antiresonance. This, combined with the use of a push-pull damper in the woofer assembly results in a superaccurate response at even the most subtlest of audio signals

■ Wide-range UFLC soft dome tweeter reproduces signals up to 40kHz

■ Highly rigid cast aluminium frames for both woofer and tweeter units keep unwanted vibrations and resonances to a minimum

■ Magnetically shielded - can be used in close proximity to a video monitor

■ Unique time-aligned enclosure features a baffle configuration and HP sound reflectors resulting in a near-perfect internal enclosure environment

■ Careful placement of drivers and innovative enclosure design allows for a wide optimum listening area

NF-1A

■ Dedicated bi-amplifier (60W LF + 60W HF) drives both drivers electrical isolation

■A large sized R-core power transformer ensures stability of low frequencies - even at high pressure levels

■balanced XLR and unbalanced phone input connectors

■3-point (H/H-M/L) audio adjusting filters &

independent tweeter

Near Field Studio Monitors

HYPERBOLIC PARABOLOID

DIAPHRAGM

The NF-1series employ the world’s first implementation of an HP structure in an near field monitor.

Unlike conventional diaphragms, the curved surface of the HP diaphragm offers increased responsiveness and resonance-free operation.

UFLC DIAPHRAGM

SOFT DOME TWEETER

The utilisation of a UFLC (polyUrethane Film Laminated Cloth) diaphragm in the NF-1’s soft dome tweeter allows for the highest possible fidelity and sound reproduction - even at extremely high frequencies. Something which, until now, has not been possible with conventional soft dome technologies.

True and accurate monitoring is the utopia sought by recording studios, video post houses, remote broadcast facilities and project studios the world over. Monitoring which truthfully reproduce all aspects of the program material free from any sonic coloration and distortion.

Yet this is exactly what the new and innovative Fostex NF-1 (passive) and NF-1A (active) Near Field Studio Monitors do.

Nothing more, nothing less.

And at any volume.

Here are nearfield reference monitors meticulously designed to be completely neutral, to offer the widest frequency range, to minimise listening fatigue and to allow you to accurately pinpoint and analyse all aspects of your creative output.

In short, they set a new standard. But isn’t this something you have

heard before? After all, many manufactures will make the same sort of claims for their studio monitors. But few, if any back it up with hard, scientific facts.

Fostex however can and do, because they’ve made real advances in speaker and enclosure design technology which has resulted in, what could be, the perfect reference monitor.

BLANK SHEET OF PAPER

So what makes the NF-1 series so different? For a start, Fostex started with a blank sheet of paper when designing the three crucial components of the NF-1/NF-1A; the low frequency woofer unit, the high frequency tweeter unit and the speaker enclosure.

Nothing was taken for granted. Nothing was assumed.

A BREAKTHROUGH

IN DRIVER TECHNOLOGY

By using an HP diaphragm, the NF-1/NF-1A set new standards in driver unit design.

HP DIAPHRAGM

The NF-1/NF-1A employ a completely new type of low frequency unit featuring a newly developed HP (Hyperbolic paraboloid) diaphragm.

The 3rd-order curved surface structure of this technology results in the ability to reproduce fasterrising sounds more responsively, the minimisation of self-resonating frequencies and the total lack of sound colorisation characteristics.

But Fostex didn’t stop there. New technology also shows itself in the UDR (Up/Down Roll) tangential edge structure of the low frequency unit. This edge is created by joining uproll and down-roll at their tangential surfaces while utilising FEM model analysis to determined the optimum bonding points.
