I would love to experience this...   Grin

"Royal Device has on its own developped and built the biggest subwoofer of the world for an AUDIO/VIDEO room that can be also considered as the geatest AUDIO ROOM for private music listening of the world. The audio reproduction is focused on the speakers output capability more than electric power output of the amplifiers with no need of KWatts power supply lines, releasing more than 110 dB/1W/1 meter sensitivity starting from below 10 Hz focused on the listening position."

Scroll half way down to see the sub chambers.

SOME FOLKS GOT WAY TOO MONEY

Thanks for the link //  Nutty

*** PEOPLE THIS IS WORTH SEEING ***

At my old studio in DETROIT  we had a pair of Hartley 24" speakers mounted in the floor. At 30 watts they were impresive, pipe organ music was the best
Dr Hartley was a nut also " The real Elephant Man "

DANO...............

Blue Device / Outstanding Web Page

What if......................

You and I build a room with the same basic floor plan but replace the 18" Laura Sub woofers with these MTX  60" Giants.

Is there something stronger than Concrete Huh?


" For earth shattering bass you canít beat this custom made 60-inch subwoofer which has the ability to produce SPL levels above 180 dB. This monster has output displacement comparable to 160+ ten-inch woofers!

The motor is capable of producing 6,000+ pounds of linear force, which is necessary when considering the very large surface area and displacement volume required to produce high SPL levels "

The first song I would like to hear  would be " InAGaDaDaVeda "

Thank you all for the kind emails.

Yes, our inside theatre setup also has a extreme Sub setup.........

Below is a photo of the subwoofer set we have inside.
New Infocus 7510 DLP has just been installed / Highest 5 Star rating on this unit
Vultec screen frame seen in photo, screen removed to show backline drivers.

Please note the pair of hand painted Tiki Lamps bought in Cuba soom years ago on one of my  *** CIGAR RUNS***
Custom flicker candle lights inside, simply outstanding to watch

The backline speaker set up includes 3 sets of Electro Voice TL 606 DW subs
228 lbs each loaded. a pair of JBL 4045 Cabinets loaded with original Altec Lansing 515 drivers. Altec 291 Mid Drivers and a pair of JBL Bullet Tweeters. Center channel, two  JBL MR 802's.
Rear channels driven by four Mach  Twos, yes that is a 1956' Electro Voice Rengency on the bottom, love my tube HI FI set


 COON CREEK

Excellent. Now we're talking. You can always turn a big system down, but a small system can never be turned up into a big system. Once you've heard a proper setup with large speakers, and the impact for movies, it is hard to go back.

Hi a friend of mine makes these, he goes down in audio ledgend as the first person to design and produce a high power amp. In the 60s world of 30-60w maximum he released a 200w.

http://www.lenardaudio.com/main/07_cinema.html

Here in Sydney he has installed one of those big systems into a 375 seat cinema (see photo). It has 6x hornloaded subbass flat from 27hz! He just built a system for a multi millionaire, which features 4 x 28" woofers (-3db@16hz). photos are on his website under opals series.

My own sub is rairly pulled out in respect of my many neighbours though, its a 12" car stereo speaker with a 100w sub amp sitting in a 8ft length of sonotube ( used for pouring concrete) with some fiberglass insulation behind. Its design is based on 1/4 wave length theory. response from 22 hz.

I made an 18" 4 inch voice coil version for a 250 seat cinema! They seem pretty happy with the results.

Ok, I'll play along

How does 4) B-52 ACT-18's grab ya?  1000W cont. / 2000W peak 135dB (138dB when coupled)
Powered by 2) QSC RMX-2450's run in bridged mono mode (2400W) yeppers that'd be a total of just under 5000W avail just for the subs.

Tops are generally anywhere between 2-4 ElectroVoice Sx300's at 300W/1200W each being driven from a QSC GX5 (500W/C)

And awesome flick was the first installment of National Treasure when they blew up the old sailing ship but then again so are some of the old Star Wars / Star Trek movies with exploding death stars and such.

There is simply no replacement for cubic displacement.

AS a FOH Soundman We used many QSC's over the years but are back to the Crowns, just a better ( tighter) sound with more headroom.
We overhauld our Drive In set with a pair of the new I TECH 8000 Crowns ( at 22 lbs each !! )
A pair of JBL SRX 725's and two SRX 18's. The Altec handles sub at 500 hz down with two EV 15B's
Nothing against QCS's but they are for Rock groups that wish DB's over clarity

True, but as a small rental company my average client can not afford the likes of an iTech and the QSC has proven nearly indestructable.

Question... Can anyone tell me what they call that metal contraption on the very top of this screen?  I am going to attempt to put up a screen from carlsscreens that I can put up for shows and then take down and roll up when not in use.  The screen is 9' x 16', and I dont want to use braces if I can help it.  So to avoid sagging, I figured Id use something like this to hang my screen from, and bungie the screen to the sides, and finally ancore it to the ground.  Any thoughts on this set up, and again, what do you call the bracket type looking thing that spans accross the top of this guys set up??? Thanks for the help.  Doug

Jon- Thanks alot for the ans!  I'm sure with some of the new comers, you guys must just shake your head at some of the questions we have.  But so far I havent read to many impatient responses.  Maybe I can push you jst a little but further for info...  What I am thinking of doing is have a 16' or 22' screen from carls place (BOC).  I want to weld a couple of 90 Elbows onto the ends of this truss, and just slip some 10' fence post into the elbows and raise the screen into the air, then Im gonna bury a sleeve into concrete into the ground that the same post will just slip into.  so truss accross the top, elbows at the end to accept the round fence post, and slide the posts into the ground- then use bungie to fasten the screen all the way around the frame... What do you think???  Most important, I want to be able to roll the screen up around the truss once I take the screen down after the show.  But im not sure if this would make the BOC wrinkle like crazy??? Any thoughts??? Thanks again buddy.  Doug

OK OK- Sorry to break up the party, but Im trying to decide on a truss to runn  across the top of my 16 ' carl place screen (without having to use braces).  I  founf some 6" triange truss I could buy that come in 4' or 6' sections.  Here is the question... If I connect these sections to span the 16', will they sag because there are so many connections.  I could buy one solid piece, but that would cost $400!!!!  I can tell from the screen in the pic, but is is one piece-If not, then how many pieces and does it bow, and lastly, what are the chances of finding one of these trusses for less?Huh? Thanks for helping.  Doug
