The Carlsson OA-51.2 was the upgraded version of OA-51. This model was not sold a speaker pair, only as an upgrade kit to owners of OA-51.
\nThe upgrade consisted of new improved woofers, tweeters and crossovers.
\nThe woofer was the Scan-Speak 18W\/8545 replacing the older 18W\/8542. The 8545 has lower distortion and age resistant surrounds etc. The tweeter is a Vifa aluminium dome tweeter. The crossover is a 6\/12 dB with high quality components
\nAfter upgrading the speakers you still have a speaker with almost the same looks but with better performance. The elements are more modern and up to date giving you a speaker according to the same principles but with the benefit of the more recent speaker developments.<\/p>\n

Restoration<\/strong>
\nOA-51.2 is still so new so it\u2019s not likely to be in need of a restoration yet.
\nWhen that time comes it is however easy to restore according to \u201crestoration and upgrading\u201d.<\/p>\n

Re-veneering<\/strong>
\nThis is deemed to be difficult to do effectively with a good result so there is no fixed price for this. Re-veneering is however not impossible, all questions regarding this should be addressed to:

New grill<\/strong>
\nThe original foam front is most likely ruined by now. Therefore a new protective wire grill has been developed for the speaker instead.<\/p>\n

New damping material for the absorbent panels. <\/strong>
\nThe panels have also by now most likely deteriorated. New damping material is available.
