Can I use an isolation stand with an isolation pad?


I bought a 5.1 surround sound system recently, and got an IsoAccoustics isolation stand for my subwoofer. Unfortunately my neighbor below me can hear the bass if I'm watching a loud movie (in a condo, hardwood floors). I'm wondering if I should buy an isolation pad - like the Auralex Subdude HT - for under the stand, or if there might be a better approach? The music store I went to steered me away from isolation pads and towards the stand, but it's clearly not doing enough on its own. Thanks to anyone with advice!

In the end 20hz tone is 56.5 ft long so your neighbour will almost always hear the bass louder then you. even a 40hz tone is 28ft long so bass is always a hard thing to tame in smaller spaces. I've seen an issues were my friend had no bass in his apartments but his neighbour down the hall was booming really loud. Bass traps may help but probably not much for your neighbours. turn it down is really the only thing you can do other then what you have already done...not ideal to be that close to neighbours and love audio-movies I feel your pain I'm in a similar situation.
Springs, my friend. Especially for subwoofers as they produce very low frequencies, unlike your average full range speaker.
 Of, course it helps to know what you’re doing. No offense to you personally.
