Sb acoustic substitute for sonab?

Post by quadmatrix82 »

SB Acoustics SB17NRXC35-8 was recommended to me as a potential substitute for sonab oa-12 I noticed this speaker isn't mentioned on this forum or carlsson kult as a potential substitute.

Has anyone had experience with this woofer and based on the specs would it be suitable for the oa-12 replacing the sc-165?

I use SB acoustics Satoris with my OA 12´s. Check out Carlssonkult.se for further instructions (and translate).
This woofer is much, much better than the original woofer. Much less distorsion I reckon.

Thanks for that I am also aware of this model you suggest but it's too expensive the ones listed that I mentioned seems much cheaper and I wonder if it is a close match to original sc165?

The search has been on a long time. I don´t know if this particular woofer suits the OA 12. If so, I think someone would have found it a long time ago. OK, it´s cheaper but an "original" SC 165 (B 65 OA II) is not so much dearer. It will suit the OA 12 very well, albeit with rather more distorsion than the Satori (which is Indonesian by the way).
On the other hand - I know of people that has bought cheap elements, put them in their OA - speakers and hasn´t heard any differences at all.
