It's a symmetrical, folded, tapped horn.

It's only 600mm deep as well. ------------- It just is. |

It is just ~45Hz tapped horn.. Basic plan layout idea was few years old when I have designed sub for line array sys. but that cabinet was pretty much larger than this "Cyclops" prototype.
Initiated by Nick's (The Builder) http://www.freespeakerplans.com/index.php?option=com_jfusion&Itemid=64&jfile=viewtopic.php&f=39&t=1086&start=10 - topic on FSP I came to idea to make some compact (as possible) and loud "universal" -without kick bin bass cabinet to cover ~45 - 130Hz range (in multiples will do 40Hz ..even a bit under I expect).
It is posible to easily modify design to get even single starts very loud stright from 40 Hz but than cabinet size will be larger and goal of "compactness" will be a bit sacrificed.
Dimension of cabinet is H=1052mm, W=576mm (truckpack f.) , D=618mm ~ 375liters overall which is less than most standard double 18 BR-s
I have few ideas on mind while drawing this plans .. as symetrical cone loading, position of speaker to improve usable upper end or responce, cooling..
It is possible to fit lower extension TH within same dimensions of cabinet but in that case I have to sacrifice some of ideas noted above which will drag cabinet closer to "scoop field" and than kick bin may be required what I have aimed to avoid.
BIG THANKS TO NICK for building and testing.

Posted By: staiper
Date Posted: 28 May 2010 at 4:33pm
Yes in fact I have thought about this as "universal" PA cabinet to be loud and defined for live gigs. Tried to pick benefits of tapped horn tech. but without need for single cabinet to hit super-low freq. to keep cabinet size manageable easily enough by two persons. ------------- Just do it! ..or do not.. ;) |

 Also as you can see I have slight irrational phobia of "aces panels" on cabinets ..so I am trying to avoid them where ever I can .. (OK happened on some designs ..cant help)+ this one is designed so many panels share same dimensions (color-coded same on part list) which may simplify and help on panel-cutting preparation phase. Despite layout is pretty straightforward cabinet assembling requires good thought before about gluing/fixing order. Also important to start and keep things absolutely symmetrical. ------------- Just do it! ..or do not.. ;) |

Can anyone help me with modeling this one? If its like other tapped horns, i'm guessing it will be ok to build a 12inch version by just adjusting the width of the cabinet to accommodate the smaller driver (leaving the other dimensions the same). Mainly though, im interested in building a quad-10inch version of this. Can anyone recommend a cheap but big, big xmax 10 inch driver? I was thinking it would be heavy, but it would be an absolutely amazing bass guitar amp as well as an all round bass solution. |

"If its like other tapped horns, i'm guessing it will be ok to build a
12inch version by just adjusting the width of the cabinet to accommodate
the smaller driver (leaving the other dimensions the same)." For best results, learn how to use Hornresp and model it before build. ------------- djk |

My GUESS at hornresp inputs: Note Le is unknown - I believe this can make a fair bit of difference in a tapped horn. Nice design Stipe! Like the handle positioning. I've been wanting to do something like this in a 12" version but mine would sacrifice some max output in favour of a little low extension. This cab seems to have excellent excursion control above 45Hz. I know it's weird but I've got a suspicion that high excursion control at tuning frequency might be what killed my Ciare 12SW (end of coil sitting outside the gap at high power so not much movement to allow cooling). I wonder whether underhung coils (XBL^2?) would get the most from tapped horns? |

im looking at a very high excursion car audio driver for this exact reason. not underhung, but a 15mm top plate should help get some more heat away. ------------- REFLEX ALL THE WAY.... (however, im playing with horns again...) That ok Mister Valiant? :) |

here are some plots, I used the input parameters from darkmatter: input screen:  black is void v18-1000 and grey is pd186, (the fane 1000 is the same as v18-1000, at least i don't see any difference between the two)  all drivers do reach xmax at 42 hz with 1000w, so anything above 42 hz under 1000w should be fine.

Posted By: daywalk3r

Beyma 18G400 in original (unmodified) CB-18: ===================================== SPL 2pi @ 1W (Beyma 18G400, Fane 18-1000)  group delay (Beyma 18G400, Fane 18-1000)  cone displacement @ rated power (400W)  SPL 2pi @ 4*400W (4 cabs on ground)  ===================================== Relatively good group delay figures. Should be "honk-safe" till at least 130Hz. The driver is exceeding Xmax at rated power by about 1mm (@58Hz), at least according to the Hornresp guesstimates.. However, 18G400 is an older model, and its specs from times when the BL fudge-factor was not "invented" yet.. By looking at the aged datasheet, it seems that the Xmax value of 7mm was calculated for close to 100% BL - which means that going 1mm over it should not be a problem. Should be safe and sound good from 38Hz+ @ 400W. Cheers. |
