Great product. The locking system is excellent. However, an oversight on my part...
I was so caught up in the locking system that I didn't realise these poles don't adjust in height...why??? I use 15" subs and 12" tops, tops sit quite a bit lower than I'd like, or would normally set level at. It's fine if speakers are sittting on stage, but if positioned on floor, the tops will sit a few inches lower than ear level. Not ideal.
Why K&M?!
