Near Field Studio Monitors

NF- Series 1

PROFESSIONAL

Main features

I 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 I 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 I Wide-range UFLC soft dome tweeter reproduces signals up to 40kHz I Highly rigid cast aluminium frames for both woofer and tweeter units keep unwanted vibrations and resonances to a minimum I Magnetically shielded - can be used in close proximity to a video monitor I Unique time-aligned enclosure features a baffle configuration and HP sound reflectors resulting in a near-perfect internal enclosure environment I Careful placement of drivers and innovative enclosure design allows for a wide optimum listening area

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 theyve made real advances in speaker and enclosure design technology which has resulted in, what could be, the perfect reference

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.
I Dedicated bi-amplifier (60W LF + 60W HF) drives both drivers electrical isolation I A large sized R-core power transformer ensures stability of low frequencies - even at high pressure levels I balanced XLR and unbalanced phone input connectors I 3-point (H/H-M/L) audio adjusting filters & independent tweeter control
UFLC DIAPHRAGM SOFT DOME TWEETER The utilisation of a UFLC (polyUrethane Film Laminated Cloth) diaphragm in the NF-1s 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.
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 isnt this something you have

HP DIAPHRAGM

The NF-1/NF-1A new HP employ type of a low completely developed
frequency unit featuring a newly (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 didnt 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 upA BREAKTHROUGH IN DRIVER TECHNOLOGY By using an HP diaphragm, the NF-1/NF-1A set new standards in driver unit design.

roll and down-roll at their tangential surfaces while utilising FEM model analysis to determined the optimum bonding points.
NEWLY DESIGNED BASS REFLEX SYSTEM Although the NF-1/NF-1A uses a bass reflex enclosure, Fostex have, again, re-worked the technology to provide real gains in terms of bass response characteristics. This has involved the active utilisation of the reverberent sound caused by the internal HP reflectors which exits the enclosure through the two bass-reflex ports. (Something which is just not possible with enclosures which only use conventional glass fibre for internal damping). The placement of the exit ports was also critical in allowing a smooth and natural blending of the sound coming from the woofer and tweeter units.
It is this edge which plays a key part in the overall performance of the units.

SOFT DOME HF UNIT

Fostex could have opted for a standard soft dome tweeter for the NF-1/NF-1A. But as good as these are in standard form, Fostex felt the need to develop a new type of soft dome unit, one which features UFLC in its construction. Conventional soft dome units exhibit minute pinholes in the damping materials resulting in dips in the frequency response. In using UFLC materials, Fostex have eliminated these, made a 30% weight reduction and widened the frequency response across the range. But all this attention to detail would have counted for nothing if Fostex had, like others, used plastic or pressed metal driver frame

THE TRUTH

Hooking up a pair of Fostex NF-1s or NF-1As for the first time is somewhat of a revelation. You may be surprised at what you hear. Your material may sound better. It may sound worse. But at least it will be a true representation, free from any sonic coloration and distortion. Which is where we came in.
NF-1 CROSSOVER DESIGN The extremely natural and ultra-smooth transition between woofer and tweeter units is due to another breakthrough in monitor design. While the high frequency UFLC tweeter unit uses a low loss 6dB crossover, the smooth roll off of the low frequency woofer, (afforded by the unique HP diaphragm technology), renders the use of a crossover for this unit obsolete.

INTERNAL ARCHITECTURE The internal architecture of an NF-1/NF-1A has been acoustically designed to minimise resonances and vibration which can add unwanted colour to the sound. HP SOUND REFLECTORS The inclusion of HP sound reflectors prevents the generation of standing waves in the enclosure. Like the HP drivers, the constantly varying 3rd-order curved surface of the HP reflectors, along with their carbon fibre/PBO construction minimises self resonance.

NF1A Amplifier

DEDICATED & ACOUSTICALLY ISOLATED BI-AMPLIFIER The NF-1A features a fully independent bi-amplifier with 60W of independent power available for both the Low and High frequencies. This ensures that each unit is driven in perfect electrical isolation. The amplifier is also cleverly installed ensuring that unwanted vibrations are kept to an absolute minimum. R-CORE TRANSFORMER The large sized R-core transformer supplies more than enough power to ensure that the Low frequencies maintain their integrity - even at high sound pressure levels. FLEXIBLE FILTERING Adjusting filters include LO FREQ (+3, 0, -3dB @ 60Hz), HI-MID ATT (0, -3dB) and HI FREQ (+3, 0, -3dB). An independent tweeter control (-3dB to +3dB variable) is also present. Crossover point is set at 5kHz).
