A:AnswerYes, technically they will by weight. The polks weigh 8 pounds and the stands are rated at 10 pounds max. They are restrictive on speaker wire size, for example best buy's s16 gauge will not fit in the stand. The mounting hardware included offer many solutions but my expectations are you'll have to run screws into your speakers case to hold them on the stand. They have a fairly study base and are decently built but it's a real top heavy setup
A:AnswerYes, the stands come with multiple brackets and screws for you to choose how you would like to secure the speakers. There are options that would work well with the Due's keyhole mounting slots.
A:AnswerThey worked with my Bose Acoustimass series cube speakers, not sure how similar the mount points are on cinema series. These speaker mounts come with a number of different types of speaker mounts, you should be able to find one in the kit that is suitable. These stands are well made and the bases are heavy duty. Hope this helps!
A:AnswerI wouldn’t recommend because the 5 lbs speakers I used on there were very top heavy if extended up the full length. I know the Sonos weigh more and this is only suggested to 10 lbs but I wouldn’t trust that.
A:AnswerFor the Sony speakers, use the L bracket and the wall mount kit that came,with your speakers. Go to Home Depot and get either an 8 or 10 mm screw kit with the nuts. You will want them no longer than 1 1/2 inches. Put the screw through the wall mount kit ant attach on the other side with the nut. Slide the speaker onto the wall mount bracket and,there you go. I just did,that with mine when we first got it. I will post another answer with a photo when I get home.
A:AnswerThese will not fit the Bose rear speakers, I was only able to attach them with the provided adhesive, and it didn't look nice so I returned the item. My recommendation is the spend the extra money and purchase the speaker stand from bose.
A:AnswerThey worked fine for my Definitive 600 surrounds. The stands come with at least five different styles of mounting braxkets, so I imagine you could find one that will work.9
