The attachment to any support post you use is short (about 75 mm). I think that's enough, but I'd feel a little more confident if it was 100mm. Although the spec says it supports up to 10" speakers, I use mine for 12" high output speakers (QSC) and they fit and work consistently. Excellent value for money, high quality welds.
