Rated 5 out of 5 by from Worked great as a center for us. The S35 was an instant upgrade for us. We were having trouble with hearing dialogue prior to getting the S35. It made a huge difference for us.

Has the S35 been discontinued? I’m having trouble finding it anywhere online other than eBay or Walmart! Here it says it’s “archived”.. Hopefully this unit is just on back order

Asked by: ctorrez1980
Hello, The Signature series was replaced by the Signature Elite series. The S35 has been discontinued but we do still offer support and parts for the speaker if you do choose to purchase it from elsewhere.

Will this sonically pair well with my legacy RTi A7 Towers? Looking to replace my matching CSi A6 which is too large for my TV set up. Need a slim center channel that will attach to a Mantel Mount.

Asked by: Obrezki
Hello, The S35 will be a bit timbre mismatched due to the advancements in design but will mesh well with your current towers. This should be a good selection to replace your current center channel.

Is there any way to adjust the clarity of the S35? I assume this model does not have Sound Adjust. Voices are still mumbled on movies and shows. Thanks.

Asked by: bobob
Hello, You will have to adjust settings in your receiver to get the center channel to be more clear. There is no voice adjust on this speaker as that is mainly on our sound bars that are self powered. If possible, contact the manufacturer for your receiver and see what their recommendations are for settings on a center channel speaker or try running the calibration on the receiver if possible to see if that helps improve the center channel.

Can you recommend a good bookshelf speaker for with the S35 center channel? I don't have room for towers and the S20 bookshelf speakers are no longer available. Thanks

Asked by: SH117
The ES20 replaced the S20 in our lineup and will pair nicely with the S35 center channel speaker.
