This 18cm 8 ohm woofer is the product of many years research at Scanspeak R&D, Videbaek, Denmark and brings together many advancements.
Featuring a unique airflow optimised open chassis and underhung Neodymium SD-3 magnet system, this woofer is free from compression & reflection effects, resulting in highly accurate reproduction. With a rigid aluminium alloy cone, copper capped pole piece & huge linear excursion, this audiophile quality driver operates as a pure piston delivering highly accurate bass reproduction with great authority, extension and texture.

Ordered two of these tweeters on Friday afternoon NZ time, amazingly they had arrived in Auckland the following Tuesday morning, arrived in my home town of Christchurch couple of days later and were promptly installed. Seem to be doing and sound as they should, thank you for your service!
Excellent service well packed and very happy with tweeter after the work had been done.
Definitely would use again
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.
