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.

Linn Kan OW1 -92 matched pair.

I have had my Linn Kan speakers since they were new. One of the tweeters stopped working and these appeared to be the best replacement for the D20-LP-1 that the Kan speakers were fitted with.

The new OW1 tweeters are a perfect fit and easy to install. The fitting kit that was supplied had every thing needed other than tools. The age of the glue holding the fabric covers on probably helped as the covers came off without much effort and no damage.

Very pleased with the results, Linn Kans sounding better than ever.

Excellent service from Willys Hifi. Thanks!

Thanks for the review Adam !

Linn Keltik OW1 upgrade

Firstly, the service received was excellent. Couple of emails with Willy re. OW1 or OW2. They arrived next day.
I was replacing the Scanspeak tweets and was sceptical regarding possibility of much improverment. Improvement there is in 2 main areas: 1.Rhythm 2. Surprisingly bass lines are clearer and easier to follow. Id read about this some time ago, and was sceptical. But it seems to be true.
Given the "relatively" modest cost, compared with other components in the system, a very worthwhile upgrade.

Thanks for the review Steve !

Replacement for Linn AV5140 Floorstanding Speakers

I installed the Hiquphon OW1-92 Tweeter on my Linn AV5140. The sound is now just magic. I enjoy the music everyday more and more. They can fitted with minimal effort and even you have not used a soldering iron for years.
Thank you at Willy Hi-Fi for your advise and excellent service plus your manuell on web site. This was a great help too.

Thanks for the review !

Amazing upgrade for Linn Keltik.
Clarity and sound stage are massively improved over the linn 038 not to mention original tweeters. Do not hesitate and get one of these to see real difference. They are not pertruding through the dust covers if you're using these unlike any off the linn tweeters which is a bonus . Great stuff well worth the money massive thank you.

Thankyou for your review!

This is an excellent tweeter, the best replacement for your Linn Kans MK2 and Isobarik speakers. It worth paying the extra compared to the Scanspeaks as these are smoother and richer. Buy from Willy's Hifi with confidence you'll get the best customer support and service.

Thankyou for your review! Will & Caroline
