Sonab OA-5 Type II
Posted: Tue 30 Aug 2005, 04:08
I'm the proud owner of a pair of oa-5 type II speakers. Although they've sounded great in earlier days, what they're producing now is far from a natural reproduction of a recording.
The bass is still very strong and low and still sounds good. But it has some problems with high-tones. One of the speakers (which was standing in direct-sunlight) is producing a disturbed sound at certain tones. (strangely, those are mostly voices. Very high tones like drum hihats still sound reasonably). The other speaker which was lucky enough to be standing in the shadow the most of its life is better than the other one, but it's also having problems producing high tones. High tones are just way too loud, hissing and sounding a bit distorted. The nylon net protecting the speakers is also coming off, exposing them to dust and damp.
That really is a shame and it bothers me. I love those speakers and I really don't want to get rid of them. They have been used on a daily base since 1971 and I'm kind of attached to them.
My question is not íf they can get renovated, but if there are company's still doing that, or if I myself can make my speakers sound a bit better again. I've searched the net already to see if someone can get my Sonabs back to the day they were bought, but most of them are asking alot of money for it, and although I love my Sonabs, I wasn't planning on spending a fortune on them.
So, to be short, are there any wayz of improving the sound a bit myself. (you have to know first that I'm not a very handy person.) I heard from a friend of mine that rubbing the edges of the speaker with vaseline can help imroving the sound alot. What would it help if I would replace the nylon nets protecting the tweeters. Is it reasonable to keep using the old tweeters, or would it be better to replace them with other ones. (seeing the fact that they are really old and heavely used).
By the way, I've giving the individual speakers a close visual inspection, and as far as I can see, nothing is cracked or scratched. They're "only" dried out I guess.
So if anyone knows how to make my speakers a bit better, I would really like to know.
P.S. I wanted to search this forum first to see how to improve my speakers a little, but I can't read Swedish.
P.P.S. The Sonabs are still beeing used everyday, together with a pair of other speakers, because they don't sound so bad in combination with other speakers. Should I stop using them for now, or can't it do many harm?
