Yeah,
 
But I ain't larry or barrarcuda. A quick look at another of my websites should clear that up Trev.
 
I did cut myself out in photoshop, but put me back exactly where I was in the original pic. I did this as I took the photo under fluorescent lights and it put a green cast on everything. If I corrected the colours for the bass cabs then I would have turned out orange. So by having me and the cabs as seperate layers I can get the correct colour balance on everything. For those that want to know I always set the white balance to 5500K and then adjust either the RAW file during conversion or in photoshop.
 
Here is a crop of the original pic before any post processing.
 
 
Also worth noting in the pic of the horns positioned horizontally is that each cab measures 2.4 meters wide x 1.2 meters deep x 600 mm high. So 3 cabs would be 1.8 meters high and guess what, I'm 1.81 meters tall, so you're good Mircea, but not that good, ha ha.
 
The driver in each cab is a modded version of the V18-1200 and the horn length is 5 meters. You need all 4 cabs to make up a horn with a big enough mouth to be able to make use of the 5 meter horn length. You can use 2 cabs, but there is a drop off below 35Hz then. The throat of the Rubics design places even loading over the entire cone, so its not like a normal scoop with a throat at one end of the front chamber. The throat is placed centrally and in the middle of the rear of the driver in this design.
 
This is a prototype Mircea, so no handles, but I know where they would go.
 
Yes the catches are strong enough Mykey. Each one can pull down with a force of 600Kg. The whole system is very quick to put together. It takes less that 2 mins to attach 2 sections together. The seal is rebated into the end and is a neopreane rubber like used for diving suits and studio sound proofing. If it can last 20 years next to a divers tackle, its good enough for me. The catches sit beneath the external of each cab, so 2 cabs can touch each other when stacked. And no, there are no rattles between sections.
 
Each section is 1200 x 1200 x 600, so a little bigger than a normal scoop, but you can't really compare 4, 8 or even 16 scoops against the Rubic, as no matter how many normal scoops you have you will never start hitting to below 35Hz. It takes a really long horn with big enough mouth to hit 35hz and below, let alone 25Hz.

Rog.. I'm assuming this design is for pure sub - bass (i.e 80hz and down).. so in use you would need kicks and of course mid tops above.
 
How would you go about stacking that? it's bloody large init!!? (very tall)

fair play rog, good to see something different, bit of a niche market, but thats a good thing.
its the only way to go if you have a "no compromise especialy size" attitude towards a particular design........ if your willing to spend the dosh on the right drivers + materials, and spend the time designing it properly, and are willing to accept that loud and low usualy means big cab, and you are designing a box for a large venue then this has to be the way forward? [discounting things like robbos ravehorn etc....]
nice looking boxes, how low do they drop???
nice!!!!!!!
me so horny me love you long throw
horn loaded for her pleasure

Adam,
 
I'm not finding the need to use kick bins with the Rubic. Of course it will never have the speed of a horn loaded 15" designed just for 80Hz +, but I'm so surpised at how quick it is. It was the first thing that grabbed me. Yes it plays low, to around 25Hz, but it was the speed and amount of kick that blew me away. I've tried mid tops with 12" horns crossing over at 130Hz and I don't feel there's anything missing.
 
It is big but that whole stack of 4 horns took less that 8 mins to put up. You lay down 2 sections on there backs and do up 4 of the catches, then tilt it forwards a bit and do up the final 2 catches at the rear. Then if you want to do them vertically just lift up one end and push it untill its upright. What you have to remember is that its not too heavy. The bottom section without driver is around 45Kgs, and the top section is only a bit more than a normal scoop.

another q : What made you choose a rear loaded horn rather than and enclosed / front loaded.. simply the best design for getting the depth of response? or wanting to keep the kick from the direct radiating prt (the old argument for scoop bins)??
 
Or was the goal the ultimate scoop bin.. as they do seam to be coming back into fashion now??
 
Just wondered.

i wouldnt say foolish, id like some boxes that sort of size if i had transport etc, the efficiency would be amazing compared to any other design capable of playing that frequency range.....
imagine doing something like that [maybey less tall and more wide to allow kicks and mid his] but with a front loaded horn, 25hz<80hz watt for watt it must be untouchable ???
