For some time, Hiquphon's rather fine OW1-92
tweeter has been favoured as an upgrade or replacement unit for those
speakers for which the original tweeters are no longer available.
Speaker such as Katan, Ninka and Keilidh have often been equipped with
OW1-92.
Whilst these drivers are a good match in a passive system with its large phase errors and crossover approximations, in an Exakt system, a more precise match is required.
Therefore SpeakerFilters is very pleased to announce the latest in a range of Exakt filters designed specifically for the OW1-92 tweeter in classic speakers - the evergreen Ninka floorstander.
Customer EB, Germany: "the filters working very fine for me, the sound of the Ninkas with your Exakt filters is absolutely fantastic"
These filters are available now for £195 a pair.

Every SpeakerFilters set of filters comes with a no cost 2 week trial period.
