Questions about BT77

For smaller speakers, you can use wooden wedges on either side, which will not detract from the aesthetics or stability. The minimum is 142mm, so if the speakers are 100mm, 2 shims of 20mm are required, so it's not the ideal support for this type of speaker, but it can be done....

According to the supplier's information, the bracket with the holes on the side is shipped with this product. The rear pictures with the slots show a different product, at least they do not correspond to the information provided by the supplier.
Thank you for pointing this out, I will pass this on internally to the relevant department and hope to have it checked as soon as possible.

The way the speaker looks in the photos, the bracket would not be ideal because of the slopes at the bottom. The cheeks that are supposed to hold the speaker would come to rest on the slopes and would not hold the speaker securely. I use the bracket with straight-cut speakers and it works fine.

Based on comments from previous buyers, it seems that the dowels and wood screws are included.
