Presentation
The 21447 Short M20 connecting tube from K&M makes speaker coupling easier.
Mounted on a subwoofer, it can accommodate on its upper end, 102 mm high and 35 to 37 mm in diameter, a speaker weighing up to 35 kg thanks to a unique and patented system. This, the “Ring Lock”, comes in the form of an expansion mandrel intended for rigid locking of the enclosure.
Its bottom end takes the form of an M20 threaded bolt, to be screwed firmly into the mounting plate of your subwoofer.
With its height of only 245 mm, this tube is designed to make short connections. Made of steel, it benefits above all from German manufacturing, a guarantee of solidity.
For safe and durable use of the 21447 M20 Short Link Tube, make sure the weight of your subwoofer is greater than that of your speakers. Install your system on a flat, stable surface. Also check that the tightening of the M20 bolt is free of play.
