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.

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.
Thanks for the review Andrew !

My tweeters arrived way quicker than I expected! Great service from Willys Hill. I've brought other components in the past and will buy again. Cheers.

I have received and installed the Hiquphon OW1-92 in to my Linn Kans. The upgrade in sound quality is astonishing. The definition and clarity of the higher frequencies have transformed the overall performance and soundstage to a whole new level of quality. A very good value purchase. I definitely recommend to others.
Thanks for the review - enjoy the tweeters !

These tweeters are worth the investment in my original 2000 purchased ELA mk2s. To remove the original ELA tweeter simply use a Swiss Army knife's corkscrew to lever the tweeter at its drilled fixing holes. Having broken the bitumen sealant's seal , which will probably have dried out, use a small diameter Allen key to lever the original tweeter out of the enclosure. Having packed the space behind each tweeter with extra wool damping, and applied the adhesive sealant strip to the enclosure's inner edge, as helpfully supplied by Will., I followed the excellent Hiquphon soldering tutorial to solder the new tweeter and then bolted each in place, This has totally revived my ELAs . I also removed the each speakers quarter-wave ports' perished damping and re-filled a third of each port with solid packing foam and the remainder with loose wool. The result is a hugely improved bass response. Thank you Will for your excellent service as this is an improvement to an ELA that is easy to recommend - a no brainer in my opinion!
Thanks for the review !

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!

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.
