I thought Kudos X2, which are tiny, might suit, but checking them out I find they are 780mm tall. Hmm.
If you can find a pair in good nick, Ruark's Templar loudspeakers were lovely and come in at a mere 700mm, with a backward sloping front baffle to angle the sound upwards to the listening position.
Failing that, standmounts may be the only way to go. Martin Logan make some very nice folded tweeter-eqipped standmounts (the Motion 15 and Motion 35XT) with sloping tops and I have heard they can be placed upside down meaning they are then angled upwards, again towards the listening position. Would work well, I think, in a Marantz /Arcam system.
