Atmasphere, Not True. XA Reference Towers was the tallest at 72". I have a pair, and they are magnificent!
I had the Type A IIIi for 18 years - one of the best speakers EVER produced. I replaced them with the XA Reference Towers, and I am very happy. These will last me till the end of my days. I think the XA series was the last best series in the Peter Snell legacy. The recent Snells are Joe D'Appolito designs, and now may get merged within the McIntosh speaker family, which also uses the D'Appolito arrays. D&M Holdings couldn't justify two premier brands overlapping and competing with each other.
I will miss Snell Acoustics, but I hope they continue their 36 year tradition of supporting every speaker they ever made.
