|Ohm C2 3-way speaker|
The Ohm C2 bookshelf speaker was introduced to the US market in 1977 and had been sold for 5 years until 1982. Considering the original retail price of $695, the C2 is clearly positioned in the high-end market. At its time, its was Ohm´s most successful and most widely known bookshelf speaker. It is a three-way speaker, having a 10 inch woofer and two tweeters (one low -, one dome super tweeter). At the back of the speaker a level controller is located to adjust the highs.
Ohm C2 restoration
An interesting fact to know is that the foam surroundings of the C2 are reversed, meaning that the bulge is directed towards the inside. However, there are apparently only refoam kits available that have the bulge towards the outside of the speaker. It is therefore quite easy to see, whether a speaker had been refoamed. After refoaming a C2 myself (See restoration guide: C2 project), I was not able to hear any decrease of sound quality after installing the foam surrounds in the “non-reverse” position. However, Ohm probably had its reasons to reverse the foam surrounds and if you can really find a reversed refoam kit for this speaker, you should make an effort to get it.
Ohm C2 price and value
The Ohm C2 speaker is one of those vintage speakers you should look for, if you are willing to put a little effort in restoring them. In good condition a pair is usually sold somewhere between $150 to $200, but you will find it at garage sales and thrift stores for $20 to $40, as many need to be refoamed. A refoaming kit for this speaker is available for about $30 and in case you really need to find individual parts of the speakers you can purchase them directly at www.ohmspeakers.com or in used condition on ebay. Occasionally, there are a few overpriced C2s on ebay for up to 400$, but I have not yet found one that has been sold. Conclusively, I believe that a fair price for a pair of C2s in decent condition lies around $80 to $150.
