This is awesome bass! That is some serious shaking!
I've peaked at 7 before as well during WOTW...trust me, the description "Very Strong, Difficult to Stand" makes perfect sense combined with that movie...
Been wanting to do this for a while, but I think I'm going to start the next chapter of the ULF Thread.
One of the attributes of a great home theater experience is that tactile feedback you experience. This was added into the ULF Card as Tactile Feedback FX. These could be suspended floors, couches, transducers, nearfield placement, riser, etc.
I think it would be very helpful to start cataloging HT Seats (couches, etc.) that have great Tactile Feedback. We could us the Vibration Meter to determine what the resonant frequency is, and then post the make and type of the couch.
If you felt my couch on these big ULF scenes, you'd think it was possessed. My couch has a resonant frequency centered at 15hz, but gets energized in the all important ULF octave between 10 and 20hz:
Wouldn't it be great if you could buy my couch or other couches like it and get that same experience?
has always talked about his couch vibrating like crazy, as proof above. The next step would be to run some sine waves to determine what that resonant frequency is.
always talks about his couch shaking like crazy, especially in the ULF region. He even gets is in the very lowest of octaves (of course you need a capable enough system to exploit that frequency; his raptors definitely fit the bill!). I'd be very interested to see the graph of his couch...and then I'd go buy one.
Now...unfortunately, my couch is no longer made...at least under the brand I bought it from (Sofa Express) as they went out of business. But I'll list mine anyway:
Sofa Express (discontinued) - 3pc couch, Stock# 81703C, 81703L, 81706T - 15hz centered, 11hz-21hz width
I'll update one of my posts at the beginning of the thread to keep track of the couches so that folks can potentially find and buy these HT Seats for their own room.
If you don't have an Android phone, or don't have the time to plot, just sit on your couch and run through some sine waves and document where it starts (and stops) shaking.
Who knows...there could be a couch right now at Ikea, that is available to everyone that is excited across the entire ULF band...for $500.
So if you have one, please post it!
