"The perfect two-way!”
- was what the Swedish magazine Hifi & Musik wrote 1996 in an overwhelmingly review of Stig Carlssons new version of OA-50, the OA-50.2. It really is an experience to hear either one of the last completed designs from Stig Carlssons hand. Reviews from the time they were introduced talked about how the back wall of the listening room was removed when the Carlsson OA-50.2 or OA-52.2 was used. Others called the updated OA-50.2 a “price chock”. The OA-50.2 woofer was the SC-165 MkIV. The Peerless woofer now was fitted with a short circuit ring, age proof rubber surrounds, and lower distortion.
The tweeter is the same 25 mm metal dome Vifa as used in many other speakers at the time like Thiel 3,6 etc. The crossovers were made from air wound inductors and plastic film capacitors carefully selected for their sonic properties. The OA-50.2 was produced from 1996 – 2002.
OA-50.2 is still so new so it’s not likely to be in need of a restoration yet.
When that time comes it is however easy to restore according to “restoration and upgrading”.
As boxes often get worn and looks used with dents, scratches and other surface damages the Carlsson factory has decided to offer re-veneering of the boxes complete with new borders and everything.
The price for re-veneering a pair of OA-50 is 2.500 SEK (ca 270 Euro).
Questions regarding this should be addressed to:

Since 2003 there is an upgrade kit available for upgrading the speaker to .3 status.
The OA-50.3 upgrade uses the new Carlsson T-11oa silk dome tweeter with new filters.
