A Subdude doesn't create any space under the speaker. Shouldn't cause any harm. Every Harbeth stand that I remember seeing is open underneath the speaker.
Two Nice Small Tweaks to Klipsch Forte III Loudspeakers
I made two small tweaks to my Forte IIIs.
First, I bought Auralex Subdude Isolation Platforms to sit underneath them. This raises them up ~2 inches and isolates them from a suspended wood floor below.
Second, I applied Dynamat to the midrange horn body. Knocking on the horn (once reinstalled) results in less ringing and noise now.
The improvements are more on the subtle end of the spectrum but surely noticeable. I thought I'd pass this along because for <$200 these tweaks are non-permanent and seem to provide as much if not more benefit than playing with cables.
