Finished in Satin Black, these Gravity speaker poles can be used with Sub-Woofers that have an M20 screw thread instead of 35mm Top Hat fittings. The "screw" fit stops any type of wobble with Top speakers and provides a very firm support solution. Gravity products are excellent quality and this adjustable speaker pole doesn't disappoint in this area. There are eight adjustable heights available from 85cm to up to 139cm, A good design feature is how the supporting pins are retained in rubber clips that are attached to the pole itself, meaning that the pin never gets lost and isn't free to damage or scratch the finish of the poles Build quality and finish is excellent. Gets 5 stars from me. Highly recommended.
