According to a support article and to the 1961 manual, the 1961 surrounds are advised to be configured in a specific order. I have read in a forum that this is true for the 1723 surrounds but not true for the 1961 surrounds. In that forum, the owner of the 1961 surrounds was saying that the 1961 pair are identical and there is no mark to identify each speaker as left and right by any means.
I checked the 1961 and the 1723 manuals and both advise configuring the speakers based on the left and right specific speakers.
<p style=“text-align: center;“>I am sure that this applies to the 1723 surrounds since a friend of mine owns them. Can someone please confirm if this applies to 1961 as well?</p>
