DRIVE UNITS BY MANUFACTURER:
Fountek NeoX1.0-B
Categories: Fountek Drive Units - All Ribbon Tweeters
UK STOCK ITEM !
The Fountek NeoX1.0 features Fountek's third generation ribbon tweeter technology. This design incorporates a larger surface area ribbon mounted in an aperiodic shallow horn resulting in an improved low end response / wider useable range with higher power handling than its predecessors. The 12x45mm ribbon is made from an ultra light (20mg) multilayer aluminium sandwich with a cross section of 0.015mm (approx 0.6 thou). Efficiency is reasonably high at 92dB.
The end tensioning clamps form a substantial heatsink for the low impedance ribbon and an impedance matching transformer is built into the back of the housing .
We recommend a minimum crossover frequency of 2.5kHz / 18db octave.
Frequency range | 1200Hz-40kHz | Nominal impedance (Zn) | 8 Ω |
Ribbon dimensions | 12x45mm | DC resistance (Ribbon) | 0.02 Ω |
Effective area (squared) | 540mm | RMS power handling | 20 W |
Crossover frequency | 2.5kHz/18db | Peak power | 38W |
Sensitivity (2.83V/1m) | 92dB | Faceplate (rectangular) | 98x69.5mm |
This is a nice tweeter! Bright, but not cold sounding - a real sparkle at the top-end which I always appreciate. Note that Willy's spec says that you should use a 3rd order (-18dB)
crossover, whereas Fountek actually specify 2nd order (-12dB) on their website - It doesn't really matter which you use, but I used 2nd order at 3.5k with no issues. Very wide dispersion characteristics make it an enjoyable listen, even well off axis. No idea about reliability yet, but I've been using it for a few months now with no issues - and sounding just as sweet as ever.
Thankyou for your review !

I've needed something like this for years, fantastic product and a lovely company to deal with. Won't be my last purchase from them
It was a nice experience to send the old filters to the UK (from the Netherlands) and get them surprisingly fast back (taking the overseas shipment into account). At first I did it wrong since I also replaced the drivers that could also be connected in a 4/6 Ohm (double coil). But after correcting and calibrating my receiver the speakers sounded great.
Thanks!
Used in a DIY LS3/5a project, with Morel CAT 298 tweeters and custom crossovers using ClarityCap CSAs. Super pleased with these woofers! I think they synergize well with the “live” thin-wall LS3/5a cabinets. The sound is neither bloated, nor thin, just revealing, spacious, and with very lifelike tone. I’m so happy with the results of this project and had a great buying experience with Willy’s. Thank you!!
I used this in custom LS3/5a speaker enclosures along with Monacor SPH-135AD woofers and custom crossovers using ClarityCap CSAs. The tweeters have a very pure sound, revealing microdetails and having a naturally smooth, response. The sound is never peaky or rough. I’m very happy with my purchase and with the service from Willys. Would buy from again for a future project!
I bought a pair of Acoustic Research AR28LS speakers back in 1985 for £129 ! After about 15 years the foam suspension had started to perish and completely failed in 2006 following a rather loud teenage party. I was never happy with the Eminence Beta-8A replacements bought from a local shop at the time, as the bass resonance was far too high. Finally decided to replace them with Monacor SPH-8M and the speakers now sound as good as new. Arrived quickly and no problems fitting. Many thanks.
