A:AnswerThe HTB3b speaker stands are designed to hold speakers up to 4lbs. Looking at the specs of your speakers, it appears they would be able to support the rear speakers.
A:AnswerThese stands are pretty versatile. Yes they will work with Samsung Speakers. They come with many different types of attachments and hardware. I used these as an alternative to the Exclusive Bose stands. They worked just fine.
A:AnswerHello Corky,
These are not designed for the Sonos One. I would recommend checking out our own website for the WSS22 which we have manufactured to fit these.

A:AnswerPrewired Bose - not without splicing. I would not recommend splicing, but you could get a gold plated plug&socket and set it up under the base. Unfortunately, the Bose plugs are bigger than the pipe stands.
