Hi, I'm considering the PMC twenty 24 for my listening room 3.5x7.5m, i listen width ways so 2.5m away from speakers. The speakers are 102.5cm +2.5mm spikes tall. Sat down on my sofa my ear canal seems to be at 105.0cm height but 101.0cm when slouched and comfy My current speakers are 99cm tall and seem to be a great height. I'm slightly concerned that the PMCs could be too tall. Any thoughts? Thanks.
