Eminent Tech TRW 17 12k$ subwoofer, has anyone including Clint/GENE tried it?

[HTHOLIC]

Audio and VideoHOLICS PAY ATTENTION.

All of you folks have been missing out, including myself

The fact that humans can hear down to 20hz but feel below it means the recently some subs have sub-20hz frequencies

But no one , clint,gene and whoeverelse on audioholics has talked about this subwoofer that goes down to 1hz!

I guess its a new dimension in HT.

I learned that Some movies use infrasound (below what the human air) can hear for special effects by their directors

If folks are taking about spending $135k for a HT in one of their rooms like gene did ($170k) all together.
Maybe it would be great to review this subwoofer, its acutally available for sale and for 20k it comes with a woofer and travel and installion for eminent are included.

Hey . I would love a review, 1hz to 30hz +-4db

http://www.eminent-tech.com/RWbrochure.htm

Feel free to chime In, Clint can deduct it from his tax returns so don't worry about people paying a lot to review it. (see dicussion) http://forums.audioholics.com/forums/showthread.php?p=273055#post273055 . Don't know about gene
though I never asked him neither did he comment.

Anyways- its always good to review new things, audioholics hasnever really reviewed infrasound equipment except for a few hz below 20 (10-20hz)

You still don't believe me- or think that I am exagerrating actually I am not: its the ONLY SUbwoofer in its class, not just some bigger and better subwoofer.

See this International Audio Review Article about the physics

ITS really the ONLY SUB woofer note the sub

its works on different acoustical principals and such. I suggest you click the links if you don't beleive me.

Clint and Gene really need to chime in on this one and discuss the articles

That's old news, where've you been?

 

[Seth=L]

Indeed, we keep seeing these threads pop up about the Rotary Woofer. It must be stuff of legend.

 

[Audioholics]

We shoudl have Gene review it in his room. Anyone who has felt a good sub in a good room at 18-20Hz should not be too eager to find anything that plays much lower... I can't imagine wanting anything that can do 1 cycle per second... If I can snap my fingers to it - it's too low.

There is content down there. If you've got the money, why not?

Why your current convential subwoofer is already obsolete! No kidding either!

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

They fault how current subwoofers work and talk about the limitations with all the physics and theories involved. Remember your high school physics class as they talk about in the article.

Its long but I am going to post it

Eminent Technology TRW-17 Subwoofer

Part I: The Only Subwoofer

I could tell you that the new TRW subwoofer from Eminent Technology is better than other subwoofers, and I'd be right. For the TRW does go far lower in bass frequency than other subwoofers, and does play bass much louder than other subwoofers, and does play bass with much better accuracy, quality, dynamic impact, and transient response than other subwoofers. I could even therefore tell you that the new TRW is the best subwoofer, and I'd be right.



But it would still be misleading for me to tell you simply that the TRW is better than other subwoofers, or is the best subwoofer, for I would not be telling you the whole truth.
The whole truth, the scientific, objective truth, is that the new Eminent Technology TRW is the ONLY subwoofer.
That's a bold assertion. How do we justify it?

You see, saying simply that the TRW is better than other subwoofers, or is the best subwoofer, implies that the TRW is just another subwoofer, and is merely bigger, better, badder than other subwoofers, i.e. that the TRW is different from other subwoofers merely as a matter of degree. And, admittedly, if we were to look simply at matters of degree, the TRW is indeed better and the best, in all the bass parameters that matter: deeper bass extension, louder quantity of bass, more accurate quality of bass, etc.


But the TRW is not merely different from other subwoofers in degree. It is also different in kind. The TRW employs a wholly different, radical new subwoofer technology. So its bass performance is also wholly different in kind from other subwoofers, not merely of the same kind and better as a matter of degree.
So the more complete truth is that the TRW is a whole new animal, a whole new kind of subwoofer. But even telling you simply this would still be misleading. It implies that the TRW merely uses an alternative type of technology, with which conventional subwoofer technology might still be competitive.

The real truth, the whole truth, goes even beyond this. The TRW does not represent just another alternative subwoofer technology. The TRW is not merely different in kind from other subwoofers.

[I]Instead, the TRW is virtually the opposite in kind from other subwoofers. In most crucial conceptual aspects, design principles, engineering parameters, and strengths vs. weaknesses, the TRW is virtually the contrary of conventional subwoofer technology and of all other subwoofers. Now, since wherever there are two contraries, then one at most can be right, and since the TRW is demonstrably very right, it logically follows that all other subwoofers, being contrary, must be very wrong.
The other subwoofers are so wrong, in the contrary design principles they employ for trying to reproduce bass, that they are not really true subwoofers. These other subwoofers, as you will see by the end of this article's technical analysis, are merely pretenders to the throne. The only true subwoofer is the TRW. So the whole truth, the only truth that does not mislead you, is that the TRW is the ONLY subwoofer.[/I]Let's take some brief looks at several concrete examples of what we mean by this opposite behavior, so you can better understand why the TRW is the only subwoofer.
AUDIOHOLICS has a 10,000 character limit so go to the link, I really want you to comment on how they could be wrong!

Another things is that using floorstanding speakers, one can crossover to this product, ie the rbh t30 or 1266.

 

[Adam]

Wow. Two posts selling the same technology in less than a day. I'll bet this guy owns stock.

 

[HTHOLIC]

lol- I wish I could afford the product.

They don't even have a stock symbol, in fact I cant afford their technology.

My emphasis is on the SCIENTIFIC aspect of it,

the International Audio review is not affialted with any company and has no ads.

http://www.iar-80.com/

Heck, maybe I should go to school Like them. Okay the first post was about the product. This post is about the sciencetific and physics behind the technology and how it is different from other woofers- I want gene/clint to comment because they went to school

If any other engineers can read through the jargon and decode it for me let me know

 

[Buckle-meister]

If any other engineers can read through the jargon and decode it for me let me know.

Firstly, the article is very badly written, taking paragraphs for what could be conveyed in sentances. It waffles, which immediately gives it a lack of credibility.

The article fails to mention that in a normal living environment, a good sub will effectively radiate those frequencies that matter for music and home theatre playback.

The article notes that the sub effotlessly goes down to 0Hz. That's excellent...except that, um, there's no noise at 0Hz. Besides, a sub that goes below 20Hz is, I would've thought, synonymous with a tweeter that goes above 20kHz; most of us can't hear and most recordings dont contain those frequencies.

The most obvious question, however, is: why, if the technology is relatively old, hasn't it been perfected and everybody using it?

Something doesn't ring true.

 

[MACCA350]

1) Old news

2) Only good from 20Hz down

Yeah its pretty cool, but you still need a subwoofer. It's a supplement, not a replacement.

cheers

I was under the impression that some movies (I have heard Gladiator) went all the way down to 2Hz have I just missheard?

I do agree though, a little sketchy with the 0Hz thing. LOOK MY SPEAKERS ARE PERFECTLY SILENT .

 

[Audioholics]

Because you're better off having someone come up to you and slap you in the face - same effect... Think about what 1 Hz is for a second... every second there is a pulse... as far as I can imagine that's stupid. I also know for a fact that if there is content below 16Hz in a soundtrack it is entirely accidental as no soundstage or editing suite I am aware of can play back anything below that range.

 

[avaserfi]

Makes perfect sense for them to not go that low. I had just read somewhere but wasn't sure. Although it would be pretty cool to have your *** kicked by audio equipment, literally, and pay 20k just to have it happen. Hah.

 

[Seth=L]

I would like to see Resident Evil: Apocalypse blow the rotary woofer, I bet that movie can't blow it up. I should get a rotary woofer just to show that F'ing Resident Evil: Apocalypse who's boss.


(F you Resident Evil: Apocalypse, Spiderman 3 Trailer, and some 11hz test tone from my computer for blowing my Miller & Kreisel MX-100 3 DARN TIMES, I CURSE YOU ALL!)

 

[HTHOLIC]

Actually if you read the 13 pages

Human beings can hear below that 16hz, as the article was pointed out the human beings are insensitive to noises that low

but a high SPLs they will be able to hear that noise.


There is so much physics and information about enginnering Ill leave it up to you to start reading

http://www.iar-80.com/page142.html

By the way if your mains cross down to 30hz you can crossover to it.

You actually read the 13 pages? A normal sub cannot radiate below 10 hz, the laws of physics apply.

 

[highfihoney]

Myth busters shoulda used that thing to test the "brown note" theory,if there is a brown note that baby would let ya know

 

[spyboy]

The Thigpen Rotary is the real thing. When the price comes down, I would consider buying one. I think that there is some content between 1Hz and 16Hz that is deliberately being put into soundtracks. Something like the Wannamaker organ may be able to take advantage of the Thigpen Rotary.

All the Best

 

[MACCA350]

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

 

[Buckle-meister]

You actually read the 13 pages?

Of course I didn't read all 13 pages. After reading the first 2 or 3 I wrote the article off, and quite right too. I'm not saying the information in the article is false, only that the author makes a mountain out of a molehill.

A normal sub cannot radiate below 10 hz, the laws of physics apply.

Maybe, but who cares? A new super-fandangled sub that can go significantly below 20Hz is, by and large, a complete waste of space (and money if you're daft enough to buy one).
