Don't know if anyone else has seen this but figured I'd share.

Yes, this subject must have been buried in the grass the cows ate and gets regurgitated on a regular basis

So I took a short look at the site and have a question. What is a A-DIMENSIONAL SUBATOMIC PARTICLE ACCELERATOR for SPDIF data transmission? Is that a complicated way of saying a Optical Toslink Connection?

It's pretty clearly stated towards the end of the page:

"It is a TIME MACHINE that returns back in time, restoring completely the recording by eliminating all the distortion accumulated by the recording processing. . .

Any type of talking is useless. It has to be heard."

Shucks, I want one.

So that's what it is.

I think this goes back to the Tuba 96 request just make it 96 x 48 x 48. Two of them corner loaded with a v-plate.

PFFT! anything less than 49" wide and it's not a REAL t96.

and same thing goes for the vplate:
PFFFT! just use four of those babies per stack and there's no need for one

And if you want to take to the EXTREME!! then just use eight per stack and you don't even need a corner anymore!

TAKE THAT omnidirectional frequencies!

Oops. Forgot that extra inch - don't want to make extra cuts.

So that is 1,045 cu ft of sub - what tops do I need to keep up? My estimate is a LOT of DR250's.

And totally clueless. This classic is what happens when someone with more money than brains contracts someone with more greed than scruples.

Oh that's easy too.

While the dr250's would work, what would work best is my version* of the dr300 which a quad-loaded cab. And just for this setup I thought of everything and came up with two models: one is a curved model and the other one is straight which would stack on top of the curved one. Now, if you're not comfortable with building dr's remember there's still the otops which the version* i came up for this is an octo-loaded cab. However, this only come in straight arrays an not curved. Genius indeed!


* - this consists of making a lot of cabs and sticking them together with pl and some wedges for the "straight" array and then some more pl between the wedges.

[jjohnson]

dr300 ... quad-loaded cab.

I think I need eight of the those. The whole package of T96's and
Quad DR300's will be powered by my anti-matter reactor connected to the SUBATOMIC PARTICLE ACCELERATOR making each of these work at 200%
efficiency.

Ummmm. Where to start...?


Obviously I never heard this room but:

"TOTAL LENGHT OF THE HORN is roughly 9,3 + 2,7 + 6 + 2,5= 20, 5 meters" according to that website....but everything after the 9.3m is room loading, pretty much any of the 1st couple boundaries it hit is an extension of the horn path according to these guys. BTW THT is about 4 meter path so you get about 1/2 the path in a nice 3 foot cube if you want, then just measure all your walls. Or a pair of Tuba 96s should be close depending on the folds.


Is it me or is it interesting there is no acoustical measurements of this room posted in the article? Just we went nuts and here is what we made!

1.2 gigawatts

Duh you need that to power the flux capacitor in the "SUBATOMIC PARTICLE ACCELERATOR" oh wait I mixed up my 80's movies, I knew that sounded familiar...
Thank you wiki:
The Proton Pack, designed by Dr. Egon Spengler, is a man-portable particle accelerator system that is used to create a charged particle beam - composed of protons - that is fired by the proton gun (also referred to as the "neutrona wand"). "unlicensed nuclear accelerators" ~Egon


Guess they didn't get the memo about mixing horn types and phase issues either with their 18 Laura's including the horn flair surrounds of the mains. Flair. I think Joanna only had 15 pieces of flair, the bare minimum. Not like Brian over there he has 37 pieces


Second to last....Why must people insist on putting instruments and other crap in their listening rooms and theaters. If you are going to put all the time, effort, and money into this room to make it as acoustically perfect as you can imagine, why put a drum set and guitars in there? It is a listening room not a studio, if you afford this room you can afford a studio next to it or something. Or do what I did in high school, if I wanted music to sound better than my system would allow I bought some magic brownies. Then you forgot about the system and concentrated on the music. Way easier than tweaking out a system then throwing in random objects.



"An error normally made is to consider the speaker by itself (or the amp or the cable). There is people that do not sleep at night because still is not satisfied of what he has made or bought. The final result of an audio system is proportional not to the money spent to make it, but to the amount of thinking and research one does consider from the start as the all lot of components he must at the end stuck together. As normally HI-END Audio manufactures do not provide everything and people likes to put "this" connected to "that" because " have read here and there" or "heard from somewhere else" still the problem to get a very good final result is far away to achieve.

Many times to build bass horns everybody follows manual and books (and thats good to do, theory always teaches, experience is something else), we also have books but experience is much more worth and in this case the horn MUST not be seen by itself.

Talking about a BIG HORN SUBWOOFER there is something that I think people normally forget or do not take into consideration (and maybe books do not explain) that is the dimension of the room and the position of the horn mouths toward the listening point plus the shape of the room. The second thing is that the bass or sub horn calculations are normally valid (as usual) in open air and that the room itself, if correctly used and shaped, can be considered part of the total horn below frequencies as 20 Hz."

All from the website, Wow an entire 3 paragraphs from that site that sounds eerily familiar.

/dismounting from my soap box. Thank you all for your time.
