Fountek NeoX3.0-B
Categories: Fountek Drive Units - All Ribbon Tweeters
UK STOCK ITEM
The Fountek NeoX3.0 features Fountek's third generation ribbon technology. This larger sized design incorporates an increased 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 12x80mm ribbon is made from an ultra light (36mg) multilayer aluminium sandwich with a cross section of 0.015mm (approx 0.6 thou). Efficiency is high at 95dB.
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 for ease of application.
We recommend a minimum crossover frequency of 2kHz / 18db octave.
Frequency range | 1200Hz-40kHz | Nominal impedance (Zn) | 8 Ω |
Ribbon dimensions | 12x80mm | DC resistance (Ribbon) | 0.02 Ω |
Effective area (squared) | 960mm | RMS power handling | 30 W |
Crossover frequency | 2kHz/18db | Peak power | 50W |
Sensitivity (2.83V/1m) | 95dB | Faceplate (rectangular) | 144x69.5mm |

I always knew that Linn should never have stopped using Hiquphon tweeters. What I don't know is why it's taken me thirty years to fit a pair in my old Kabers. It's often hard to describe sonic character ....but to pinch Linn's old line from back in the day ...they're Simply Better.(even straight out the box with soldering iron still warm)
As my Kabers are passive,I had been a little concerned that the the 8 ohm nominal impedence of the OW1 would mess with the crossover slope. I needn't have worried....if its shifted the crossover point its much for the better.
Warm thanks also to Will and Caroline for a service in keeping with the outstanding quality of the Hiquphon product.

Been looking for a supplier of replacement drivers for some years.
Willy's HiFi had just the parts at a good price and they arrived in a couple of days.
Excellent service. Even a personal thank you hand written on the invoice.
A quick delivery and the tweeters are perfect on my mission 753 freedom speakers. Easy to fit . Highly recommend.
I’m no expert when it comes to speakers, but after some research (and a strong recommendation from ChatGPT), I went with the SB Acoustics SB65WBAC25-4 as a reference full-range speaker in this size range.
Having now tested them, I can confidently say they’re probably the best speakers I’ve ever owned. The clarity is outstanding—every detail comes through with incredible precision. The bass is surprisingly full and punchy for a speaker this size, and they handle power impressively well. For anyone looking for a high-performance compact full-range driver, these are hard to beat.
