I am trying to decide between Clark and Aura due to budget constraints. Your comparison actually has me leaning towards Aura because of your comment regarding the Clarks feeling like they are always on. If these are correctly crossed over and the LPF and HPF are set, what causes this difference? Is it a sensitivity thing? Like the Aura require a louder "volume" at a given frequency to shake than the Clarks, or is it as simple that since the Clarks shake harder its more noticeable than the aura's?

I don't know that the auras particularly struck me - at least that I remember one way or the other to that always on effect, but I do recall that with the buttkicker vs the clark.

The clark is basically a speaker that produces tactile feedback in the same way a speaker does. If signal is applied it moved.
The buttkicker is more like a rod that is driven back and forth from what I understand. It takes a little more power to get it started - or perhaps a little more power to be noticable anyway. The clark is a good transducer. We perhaps just had it turned up too much to be as subtle as I prefer. Now that I understand a little more about the transducers I'd like to retry my experiment again - but at this point it probably won't happen. I have nearfield 18" subwoofers, and they beat the crud out of anything I've felt from the transducer world. --- the only thing better than neafield 18" are nearfied 21" or 24" subs.

Here is a member who recently purchased and measured the Aura's vibration capability on his couch in the ULF thread. 4 of these were very capable on his system; strong down to 13hz!

I had six of the transducer at the time of the test Dom. The Aura Pro's are mounted on 3 large boards in the sectional.

I have used Clark Platinums for about couple of years and more more recently have tried Aura's current offerings due to mounting constraints of some new home theater recliners.

I prefer the "subtle" feel of augmenting subwoofers as opposed to some sort of theme park experience.

If your goal is the subtle effect, I would say that Aura can offer just about the exact same subjective experience as the vastly more expensive Platinum Clark's. The overall experience to me is really indistinguishable in any way that you would consider meaningful. I don't know if the longevity of the devices will vary since I don't know the build quality of the Aura transducers. Since the construction of these things is fairly simplistic, I don't see how they would stop working unless burned out with too much power.

I am currently using a crown XLS1000 and it is pretty sufficient and can do basic crossover tasks. I am running the Aura with a 50hz high pass crossover which is pretty effective.

My subwoofers powered by 10000 watts and and 8 15" drivers can EASILY make your body move but the transducers help at nights and not to irritate the hell out of neighbors. Subwoofer vibrations don't automatically resonate with your couch evenly either which the transducers help with.


Hopefully this review helps...

Blazar!

I can see your point on the comparison of the Clark and Aura Pro. The Clark and some other brand report a response down to the 5-10 Hz but, those numbers can't be done with enough force even though the RMS wattage is much greater than the Arua Pro. The transducer are not RMS limited since they use stronger amps, the problem is excrusion. The Aura Pro's are an excellent choice for HT. I have 8 under a large sectional and get great vibrations.

Yes not only are the aura bass shaker's sufficient but really not much material is recorded in the 10-20hz range. Even if it was, the vibrations would have a good chance of rattling some part of your couch and causing problems.

the 20-50hz range via the aura feels pretty decent, and I don't feel like I am missing anything in the overall experience. in fact, for music it almost seems like its unnecessarily distracting on some tracks that are recorded too hot. I plan on setting up to not 12v trigger the bass shakers for music.

I use two Auro Pro's per recliner in my HT and that is a lot of shaking going on. I watched Fury yesterday and WOW the explosions rattled my teeth I really liked how the far off explosions you could barely hear I also gently felt. I'm using an Inter-M Reference Amp and it drives 8 total Auro's.

My riser seats which were made with a mounting board for shakers, carpet coming soon:
