If anyone is interested have a read through this guy's blog about his Dual TRW 17's(yes you heard it right....DUAL;))

cheers:)
:D, its acutally Quite interesting that you point out the link.

Frequency response, measurements,etc are mentioned, now if only I could afford the unit. It installs in the basement or attic because it so powerful.

A number of movies use infrasound. Maybe if the technology becomes more affordable (the product does have high quality parts in it that are worth the cost), it would become more mainstream.

Earthquakes and seismic waves have low frequencies too. What is interesting is that the unit can go to 30hz without much distortion and its difference from conventional woofers.

I think I'll stick with my planned 8KW 8/18 IB sub. It'll be less expensive. :p:D

Only issue is that its a conventional subwoofer

The idea behind this is that the rotary woofer can play infrasound frequencies where the law of physics dictate rules about conventional woofers. I am curious though what 8k sub brand is this? I know its just a conventional subwoofer so it has nothing to do with this new technology, but 8k is an awful lot when you can get better technology for less unless you have 4x subs in a huge huge room.

I think you misread.

8KW 8/18 IB sub = 8000Watts of power, powering 8x 18inch subwoofers in an Infinite Baffle configuration.

cheers:)

Because you're better off having someone come up to you and slap you in the face - same effect...
If I even thought of buying and installing one of those, my wife would start slapping me around at a much higher frequency than 1 Hz. :eek::(

16 Hz may not be entirely audible, but it IS perceptible. You can definitely FEEL it, so there is some benefit to having the ability to reproduce sound that low :) I have the subsonic filter on mine at 14Hz...

:eek: Maybe gene and clint and other audio engineers can disprove these scientists.

The Internatinal Audio Review who "tells it like it is" and doesnt have any sponsorship or advertising, is a group of scientists who posted this article on why the EMINENT tech is not just a better subwoofer but the only SUB (in terms of infrasound) woofer

Whoa there,

I've heard and experienced the TRW on multiple occasions, including the system referred to. Over at AVS we roasted this rambling diatribe. If there was ever a reason that writers can need editors, this is it! :rolleyes:

Don't shoot down Eminent Tech for the crazed ramblings of a third party who experienced the device. The TRW works. We don't stop hearing below some low frequency, our threshold of audibility just keeps rising as frequency lowers. We can also percieve and will react to acoustic energy at very low frequencies below the audible threshold that it is identified as an audible tone.

The most significant achievement of the device is the very low distortion reproduction of sub 20Hz energy at very high in-room levels. In short, it enables validation of the subjective benefit in reproducing such energy. I have worked with many systems that have useful response into the 10Hz region or below, and while not always easy or cost effective to achieve, there is clearly identifiable benefits in a variety of listening conditions, not just when planets explode.

I think we need to stop feeding the troll.
That is one of the most sensible things I've read in a while. And you didn't even need multiple font colors to get your point across.
