Re: OA-14: what should it sound like?

Well, I´ve heard more distorsion in my OD 11:s, compared to my OA 14. Hmm, might be because there's only one mt20 in od11 and so has been under a more heavy strain the 4 of them in oa14. But, that's just guesswork. Also, I think (at least) one of the problems he is facing w/ the treble is the (assu...

Re: OA-14: what should it sound like?

The last couple of posts suggest that the mid/bass drivers are also a source of third order harmonic distortion. I thought the distortion problem was associated solely with the tweeters? Regards IB Every driver has their share of distortion, for a mid/bass driver it is usually higher the higher you...

Re: oa14 element

Njae, så skrev inte jag. I OA50 sitter SC165III. Men det är ingen Sonab, därför står det inte Sonab på dammkåpan. Jo, mitt fel, jag antog att vi endast diskuterade oa14, jag korrigerar, alltid i oa14 sitter det sc165. Har någon någon information om att det någonsin skulle blivit laggt ett sextums e...

Re: oa14 element

Vad är det för broschyr? Jag håller med Grafpro. Jag har ingen kunskap från tiden de var nya men alla originalelement jag sett på 70-tals Sonab har haft Sonab på dammkåpan. Exakt så har jag också förstått det, alltid sc165 med 'sonab sonab sonab sonab' på dammkåpan. En finsk broschyr, "högtala...

Re: oa14 element

Jo har gjort det, grafpro menar att sc165 var det enda som var satt i oa14, därför frågar ja här.

oa14 element

Någon som har någon aning vilka element det kan ha använts i oa14 förutom sc165? Se bilaga, det står inte 'sonab' på damkåpan.

Re: OA-14: what should it sound like?

I've been using SC 165 in OD 11, and OA 14 for most of my life. The very BIG difference with Satori is the "lack" of distorsion (third). The OD 11 was replaced by OA !4 because distorsion in the OA 14 was lower. Then I changed to OA 50.3. Then I changed to Satori (phoned Grafpro first). I...

Re: OA-14: what should it sound like?

I don't agree B65oaIV beeing a "really poor chioce". It's the one carlssonplanet recommend. Whops! My bad! I sincerely apologize! It wasn't my intention at all to "talk shit" about it. I just ran a few quick simulations in Basta! and other T/S simulators and the results there di...

Re: OA-14: what should it sound like?

...what does the "distortion" sound like? How distortion works is there are manymany harmonics in what the speaker plays that is not in the signal it gets. Mostly the only ones audible in normal conditions are the first (not distortion, actual tone), the second, and the third (this one we...

Re: OA-14: what should it sound like?

I take it that the Obi tweeters are a distinct improvement? Yes, they are, the distortion, or most importantly the 3rd harmonic is well below audibility (0.1%) most of the range, closer to 2khz (from above) it starts to get a bit out of hand, but, if should you choose to go over-budget, then the sa...
