This 20mm (3/4") soft dome tweeter offers a unique analytic capability and higher sensitivity than OW1-92. A very musical and true to life tweeter! With textbook impulse response / recovery, maximum detail resolution and pair matching to within 0.5 dB, this esoteric unit projects a sublime stereo image. Excellent for use in high-end 3-way loudspeaker systems; also a great choice for 2-way systems using wide band mid-bass drivers of appropriate quality. The OW2 was designed primarily for domestic loudspeakers but is also used to high acclaim in studio monitors because of its very low distortion, analytical response and very close pair matching.

Great frequency linearity between 3 – 20 kHz, rising gently upwards - works very well in 'dead' rooms containing lots of heavy furnishings / drapes. Extremely fast transient response and excellent phase linearity.This esoteric tweeter exhibits a well controlled and damped resonance / low frequency response and gives a wide useable bandwidth of 2 kHz to 22 kHz, nominal –3 dB. Unique heavy duty 2.5mm solder bucket connectors - Hiquphon connection guide

Supplied as matched pairs to within an incredible 0.5 dB 2 kHz—20 kHz (individual graphs included), each pair is thoroughly tested before being signed off by Oskar Wrønding, the founder of Hiquphon.

SBL tweeter upgrade, worth doing.

Bought to replace oe scanspeak tweeters that had cracked surrounds. These surrounds fell apart on removal. Damage to wood in photo wasn't me. Active SBL Mk2 driven by a pair of 250DR.
Naim cabling in speaker box is 4mm so I tinned the ends then filed down to fit the buckets. Cables soak away heat so I had to use a 100w soldering iron. Gasket fitting and **** back easy.
Sound is much more open and natural. As mentioned in another review the bass is inexplicably better defined.

Thanks for the review Diccy !

Late Aktiv Kaber upgrade

I have the last version of Aktiv Kabers and changed to these tweeters around a year or so ago. Simple to fit and a direct replacement. They suit the system very well and sound much cleaner than the original 3 bar tweeters. Very happy with the sound now fully run in.

Thanks for the review Dave !

I gave Will a call , after reading about the Hiquphon replacement tweeters for Linn Keltiks.
After telling him what amps and room conditions I have, he recommended the OW2-92’s for my speakers, he gave me great confidence in his knowledge of them and the Keltiks, do I ordered them with pleasure!.
They only took a few minutes to replace in each enclosure, and i immediately had a listen,
They were initially bright and nasal, so I knocked a couple of clicks of gain off the Active board, much better!!, after a few days , I knocked another notch off gain off .
Even though the tweeters are new and need around another 100 hours of burning in, the difference to the whole sound stage is remarkable , there is so much more detail and info available, that a lot of albums I have listened to sound totally different!!,
The Bass is tighter, mid range has opened up and is sweeter and the treble is more accurate and revealing , even now with only 10 ish hours of play, the upgrade is huge!!, in current Linn terms , a multi thousand pound upgrade!!, in short , these speakers are highly recommended, if anyone who reads this fancies an upgrade to the Keltik speakers, ring Will , he’ll sort you out, my amplification comprises of 4/ 2250 D’s and Kairn pre.

Thankyou for your review Don !
