This new addition to the ground breaking Revelator series of dedicated midrange drivers features a larger 18cm sliced / glued pulp cone and a rigid titanium voice coil former. The low loss suspension and coated foam surround help this lovely unit yield a very useful sensitivity of 92 dB whilst still producing excellent midrange clarity and upper range extension. Highly recommended.

Excellent customer service
Quick dispatch
Excellent advice once again from Will so helpful. Bought and installed I was a bit apprehensive about soldering direct to the terminals including the speaker terminals but took my time and with the guidance of will these have transformed my speaker's to a completely different level. Detail clarity is outstanding brings out subtle Nuance's. I'm so glad I replaced my existing crossovers with these they are better than I could have imagined and are excellent value.
Thanks again for outstanding service.

I am a big fan of the linn range of speakers , particularly the Keilidh and Kaber models . They are well designed and extremely well constructed. Anyone thinking of taking the step on this tweeter upgrade I would say do not hesitate.! I have a passive pair of Kaber with the 3bar Linn mk2 tweeters and these are generally accepted as a decent improvement over the early ceramic versions. These OW02 Hiqufon went into my active pair of Kaber and they are in a different league in my opinion!! I am a returning customer to Willys Hifi and always get great service, items arrive on time and well packaged. Thanks for being the go-to website when it comes to thinking about my next project or upgrade! Regards Ianpop.
Replaced faulty Studio 0.5 drivers with these. Had a wobble about the fit so called to confirm details and had superb advice. Recommend both the drivers and Willy's!
I've been repairing a set of vintage speakers (Rogers JR149's) and honestly, I wouldn't have been able to do it without components and parts from Willy's Hi-fi! Thanks for the help and advice as well!
Quick shipping and high quality cloth. Very easy to work with and sticks well with contact adhesive. Very pleased with the final look!
