SVS Subwoofer Isolation feet. Will I lose bass?
bdp24 @pmg1223, in one of the Townshend Audio YouTube videos, Max explains the design and demonstrates the effectiveness of his Seismic isolator. Just do a search for the company name on YouTube, and all the videos will be made available for viewing. >>>>The Townshend video answering the questions inherent in the OP was posted yesterday morning at 10:14 by your friend and humble scribe. |
@laskakj Thanks for the real-world experience and with the same sub! That's kinda was I was suspecting. I don't like hearing the loss in "chest rattle" as that's why we buy big subs in the first place. But if the quality is that much more significant then perhaps it's worth it. I really cringe at buying MORE Gaias for my subs too though.. That's $1200 in isolation for me :( |
Actually Geoff, the video to which I’m referring is a different one. It is entitled "The effect of ground vibration on audio systems", and was taped in a private space (maybe at the Townshend facilities?). It starts with Max discussing the problem, then moving on to possible solutions. He is shown standing behind a table (and in front of a projector screen, used in his presentation), on top of which he demonstrates different forms of "mass on spring" isolation. He demonstrates the differences between spikes, a plain spring, and his Seismic Pod (which contains the same spring). He covers the issue of the undamped movement of the plain spring vs. the damped behaviour of the Pod. |
Ack-chew-ally the video I posted was actually more to the point concerning cement floors. Yours was good too. 😬 As I previously pointed out damping the springs hurts the isolation and - more importantly - is audible. 😩 The video I posted also shows that damping the speakers or mass loading is not necessary once the speakers are isolated. |
The missing “chest rattle” people report is the lack of boom and distortion when the sub is properly isolated. Key word: properly. When a speaker or sub is properly isolated the bass frequencies are lower and more articulated with more slam. Everything is better and it’s the same for any speaker. Hel-loo! What’s the hang up? Talk amongst yourselves. Smoke if ya got em. |
