I HAVE BEEN THINKING that instead of having the cab dimensions as 80x80x100cm.... why not have it 100x100x80 cm as it doesnt seem to make it unmanageable. im stuck on the flARE PROFILE! how do you calculate/design this part of the cab? any ideas ppl?

Hornresp, devide each area into diffrent sections and whatnot. it will tell you all what info it needs. this will give it a pretty accurate model of the responce. and sence it's a dual 18", make sure you tell the program that there are multiple drivers.
also a helpful hint, the program doesn't model to well above 500/600/700/800hz *to what others have mentioned before*. but no need to worry sense it's ment for bass application.

Mykey, could you give us a bit more info on this?
Preferring to use drivers in something else. So I'm a bit suprised to hear that they are "that good". |

those selenium horn Projects are meant to work in large numbers 4 per sife minimum I suspect that those people who made them didn't use enough of them to realise their potential , and just ditched them |

Correct me if I'm wrong, but that means 8 18"'s per side minimum !!!!!!!!? I dont "really" like scoops anymore, but have you heard in a single stack what 8 scoops (ASS/1850), 8 WSX_V18 or 8 Looneys(V18), 8 b'lines(1850) sound like with 1.2k of crown behind each driver? IMHO, I can see why they are are not as popular as the above or labs/punishers, but I guess I have to hear what 8 of 'em sound like.. When are yours gonna be ready HBL? |

i intend to use 4 cabs a side... so i think i will be ok. i also intend to extend the horn length by 20cm with a slightly different flare. i dont think this will make any big difference to the original plan. or will it guys?
i plan to power 4 cabs with two t.amp 3000 prolines. so they will be slightly underpowered but i havent got the money to put any more power into them.
i also plan to run 3 mt121's to 4 bass cabs.
and finally i also PLAN to have one ready in three weeks but as with past history i find it abit difficult getting things started so i wouldnt wait for my levyte if your in need urgently. i could make one out of mdf quickly but its sorting out birch ply which is bogging me down at the moment.

Making them bigger is a BAD ideea they are simply huge as they are now. you will gain verry little extension with a 20 cm flare extension do you really want to find yourself at 40 Years of age not being able to lift more than 10Kg at a time because of the back problems developed while moving Large subs? I have learned my lesson early, and I have friends in the business who would do anything to turn back the time. the 2 things that can fail verry easily while working in this domain are your Ears and your back, both are ireversible ah , and please learn how to use hornresp guessing and horns don't really go well together Edited by Nexus_3 - 25 July 2006 at 2:41pm |

Well i do own 6 double 15 selenium boxes loaded with Eminence KappaPro15LF.
Stacked all together they are brutal i the kick region but dont go as deep as i would like to.
Also they are big and not very practical so soon they will be on sale or firewood.
Now i have 12 18Sound 18W800 doing nothing so i will model a horn soon for them and make HD15's for the kappas.
So, go single and you will have more space for longer horn. Edited by MarjanM - 26 July 2006 at 5:33am |

i was a mile away with a clear view across a bay at the system and the ground felt like it was moving, so you can guess i had to go an investigate.
There were 4 doubles per side with the selenium horn loaded 2x12 and horn above
and i have never ever heard anything so tight punchy and heavenly as those 2 stack's that day.
the mid was like an axe going through my head, and you couldnt get with in 10 feet of the bin's, that were run off Crowns
they made the bins with the 1'' ply which to me made a big differance
the next day i heard a brand new EV line array, a Dynacorde that was nice, and a crap JBL line array
none of them came close to the sellenium system, all made buy a local chippy with the drawings straight from the sellenium sight
they will be using it again this year and i cant wait, ill take some pic's this time
i can find out the exact mid they built if you like?
an Ausy friend of mine here has 16 of those EAW LA400 bins and 16 full range 15'' 12'' + horn cabs, and he cant touch it for lows, punch clarity and levels, and it probably cost 20 times as much
i am making these bins as singles with 1'' birch at 600mm wide, if anybody is interested PM me
good luck

now that is a genuinely useful modification to the design, as is they wouldn't get into my storage (living room) or most of the venues we play at. clearly you aren't just hacking it in half to make a single driver variant, but have you hornresp'd your way to 600mm, or is that just an educated guess? james. |

it's an educated guess, but surely this would only be an improvement ?
and it's only 75mm added to the original when cut in half.
1000mm - 50mm for the ply = 950 divide by 2 = 475
bigger mouth, bigger driver chamber
could even do it 580 total.
and still stack them on there sides as the original, or upright (bottom to bottom) like the t18
edit. james! not even the 60ft wall of martin F2 sounded as good as the Selenium rig, and remember i dont do drugs so i wasnt influenced in anyway Edited by mykey - 26 July 2006 at 10:30am |
