When the Sonab OA-116 was introduced in 1975 the reviewers were lyrical about it.
\nSwedish magazine Radio & Television wrote: \u201cthe overall excellent characteristics give the speaker extraordinary good performance: A very large frequency range, ultra low distortion and a tonal richness in all ranges makes it unique\u201d.<\/p>\n

The first 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.<\/p>\n

The loudspeaker was equipped with a separate 5.3 ohms 6.5 inch Peerless bass element.
\nAs the midrange element an odd 16 ohms version was used and 6 pieces of 5 cm Peerless cone tweeters of which several was directed towards the listener, giving a higher level of direct sound, compared to earlier omni directional designs.<\/p>\n

With its linear tone curve (even today it is beating much more expensive high-end speakers), the OA-116 soon became a favourite among the professional musicians in Sweden. The model was however \u2013 similar to its predecessor the professional model OA-2212 – too low as a studio monitor since it most often was hidden behind the high mixer tables. Still a large number of musicians, composers, directors, music technicians and other golden ears bought a pair of OA-116 as their private home speakers.
\nMany are still using them as their reference speakers. There is a well known choir conductor using restored OA-116 in almost every room in the house! OA-116 is also the 1970-model that the Swedish sound technique guru engineer Ingvar \u00d6hman considers as his special favourite.<\/p>\n

RESTORATION
\nOA-116 is a comparatively large and hard to restore speaker, requiring that you remove both the double top baffles and the bottom baffle in order to reach the filter, cabling and bass element. It takes a long time to restore a pair of OA-116 and even if it looks easier than restoring a pair of OA-2212, you should consider if you have the time and have the energy to do a complete restoration.<\/p>\n

However what is absolutely necessary – as in all other Sonab speakers from the 1970 \u2013 is to replace the bass and midrange speakers. It is absolutely essential to do this in order to avoid destroying both the speaker elements, but also the amplifier. Additionally you should also replace the often tired and therefore whistling and beeping sound in the original tweeters against the new extraordinary Peerless CT62 (a replacement recommended by the \u201cLjudtekniska S\u00e4llskapets\u201d technical guru Engineer Ingvar \u00d6hman and also by the Stig Carlsson Foundation).<\/p>\n

More concerning restoration of the OA-116 is found in the RESTORATION section.<\/p>\n

As with the OA-2212 there are a number of OA-116 speakers in Swedish (and German) homes, modified according to the original instruction that was produced by Stig Carlsson. Two authorised companies at that time made the restoration according to these instructions. Most of this modification of the OA-116 agrees with the corresponding actions regarding the OA-2212. A complete instruction regarding the modification of the OA-116 according to the Stig Carlsson recommendations (and with the filters adapted to the CT62 tweeters) is available at CarlssonPlanet. This also discloses what exactly actually differs between the two different series of OA-116 produced (certain tweeters direction).<\/p>\n
