The OW1-92 is a 20mm (3/4") soft dome tweeter offering a superb flat frequency response with great analytic and revealing capabilities.

Beautifully neutral, relaxing and non-fatiguing sound.. this is a very musical dome tweeter. Displaying an extremely broad banded response, the OW1 has been used in a great number of high-end 2-way loudspeaker designs. The OW1 is also a perfect choice for 3-way (or more) custom built designs of the highest quality. Although primarily designed for top end domestic loudspeakers, the OW1 has gained the reputation of being a benchmark product for studio monitors and bespoke car audio.This beautiful, fastidiously produced unit displays a very neutral and low distortion response curve with superb frequency linearity - VERY flat from 2 – 20 kHz +/- 1 dB (+/- 0.5 dB typical) - an exceptional result.

Phase linearity is also excellent and the rolloff towards the upper design limit is very smooth. Multiple rear chambers yield a low and well damped resonant frequency of just 850 Hz. The frequency response climbs softly to 2 kHz then is linear to 20 kHz.Very broad-banded (1.0 kHz to 25 kHz nominal –3 dB or better).

Unique heavy duty 2.5mm solder bucket connectors - a soldering guide can be found here: Hiquphon connection guide

Supplied as matched pairs to within an incredible 0.5 dB (individual graphs included), each pair is thoroughly tested before being signed off by Oskar Wrønding, the founder of Hiquphon.

OW2 vs OW1

I originally bought a pair of OW2 in error.
I did however find them very articulate and detailed but could be a bit shrill on occasions so I ordered the OW1 as a replacement. They are smoother but I now wonder if I miss the detail of the OW2s.

Only time will tell. As ever very fast efficient service from Willys

Thanks for the review Kevin !

Hiquphon OW1-92 in Linn Ninka

Had one of the original 038/2 tweeters go on me, so decided to get some of these, as a number of people on chat forums say that they are a good replacement (even though the Linn dealer told me not to).

They are in my opinion, quite a significant upgrade from the 038/2. Brighter (which I like), but also more detail and a bigger soundstage. Easy to install (with the solder buckets), but could do with having a thicker gasket as the front plate is thinner (I guess I'll have to make some one rainy day).

I run my Ninkas Aktiv, but I suspect that you will get an even bigger difference if running passive. Highly recommend these. Probably the best value upgrade I've ever had.

Thanks for the review Bob !

What a difference!

I bought these to upgrade Keilidh tweeters, was hoping it wasn't a waste as they're, er, not cheap. I've waited a couple of weeks before posting this review, to properly listen. Well... I can't believe the difference, it's all so much more clearer, the previous harsh, tiring tone all gone. What a joy. And did I mention the clarity? Wow!

Thanks for the review Tim !

Better late than never !

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.

Exceeded all expectations.

I am writing to say how thrilled I am with the 4 new tweeters in my Linn Isobariks. The clarity and beauty of the sound is astonishing. The customer service, advice and communication was superb too.
Very many thanks.
