I still like my PMC GB1i speakers a lot. They are slim and sound great, but have one practical disadvantage in our house: our cat is heavy enough to knock them over. The relatively narrow spiked bases don’t offer much resistance against toppling. Sully, 6+ kilos .. no contest How are the steel spikes meant to “isolate” speaker cabinets from the floor, i.e. what’s the physics behind this hi-fi orthodoxy? Steel conducts sound quite well.
