Whenthe Sonab OA-116 was introduced in 1975 the reviewers were lyrical about it. Swedish magazine Radio & Television wrote: “the overall excellent characteristics give the speaker extra ordinary good performance: A very large frequency range, ultra low distortion and a tonal richness in all ranges makesit unique”.Thefirst Swedish high-end speaker worth the name had seen the light. The model defined a new and higher standard level that affected the quality requirements for the whole loudspeaker market.Theloudspeaker was equipped with a separate 5.3 ohms 6.5 inch Peerless basselement. As the midrange element an odd 16 ohms version was used and 6 pieces of 5 cmPeerless cone tweeters of which several was directed towards the listener,giving a higher level of direct sound, compared to earlier omni directional d esigns.Withits linear tone curve (even today it is beating much more expensive high-endspeakers), the OA-116 soon became a favourite among the professional musiciansin Sweden. The model was however – similar to its predecessor the professional model OA-2212 – too low as a studio monitor since it most often was hiddenbehind the high mixer tables. Still a large number of musicians, composers,directors, music technicians and other golden ears bought a pair of OA-116 astheir private home speakers. Many are still using them as their reference speakers. There is a well knownchoir conductor using restored OA-116 in almost every room in the house! OA-116is also the 1970-model that the Swedish sound technique guru engineer IngvarÖhman considers as his special favourite.TECHNICAL DATA Sonab OA-116According to theSonabs instructions manual and/or HiFi-Handboken 19788Volume: 45 litre Measures B x H x D: 26 x 67 x 46cm Weight: 21.5 kg Principle: Omni directional, bass reflex type.With increased quota between direct and reflected sound.
