Title: IMPERIAL SO PLANS Post by Steve Deckert on 10/27/05 at 20:57:47 The Imperial SO (Sub Only) plans are nearing completion. I should have them available on the site within a weeks time if all goes well. I have also been modeling various drivers that should work well in this design. Those will be posted here as well as be included in the plans.

Title: Re: IMPERIAL SO PLANS Post by gexter on 10/27/05 at 22:03:51 The Imp SO revealed! thanks Steve |

Title: Re: IMPERIAL SO PLANS Post by Hrappur on 10/27/05 at 22:27:18 Looks massive! what kind of room-size are we talking about? |
|
Title: Re: IMPERIAL SO PLANS Post by DirtDawg on 10/28/05 at 01:40:15 What's the football shape near the end of the slot all about? ??? I like to see a healthy use of bracing in a sub cab. :D |

Title: Re: IMPERIAL SO PLANS Post by bnew63 on 10/28/05 at 01:48:14 It looks like the football shape is to allow the panel to fit over the driver???.Can you hear the collective gears a grinding :D :D The iotside diamensions look very similar to the regular Imperial |

If you're wondering if your room will be big enough, then it's probably not. ;D |

I am still interested to no end about the type of driver, Just want to see how close I was. The best part of all this is we can all stop guessing and stop the fallout from the speculation. Live and learn Gex |

Title: Re: IMPERIAL SO PLANS Post by jj420 on 10/28/05 at 16:31:40 sweet manna from the Gods! i am enthralled by the beauty of the beast... nay, i am in fear. This is without a doubt the most serious bass maker I have ever seen, short of adire audio's experimental parthenon driver, but thats in a class by itself i think (120db@7((yes seven))hz OB!). oh if only i had a garage, or somewhere to put them once i was finished... :( Steve is such a nice guy for posting those preliminary plans for us fanboys, that sort of thing ensures brand loyalty, at least for me anyways. Thanks Steve |

Title: Re: IMPERIAL SO PLANS Post by jj420 on 10/28/05 at 16:40:07 after gazing for awhile, it looks to me that the sealed chamber behind the driver is surrounded by dead space, does this mean that one could adjust the volume of that space to accomodate different drivers? That would make this enclosure very adaptable to almost any driver. I see why Steve said that this might fly in the face of conventional design, i could experiment with this thing for years... Steve, could this be revised to accomodate a set of four 10" drivers? it would probably result in an increase in SQ since the motors wouldnt have to work so hard to move that big cone AND the horn too. Four motors are better than one, right? just a little brainstorm. how many sheets are we talking about here, looks like about 5 apiece, this is something i would build in i think. someone here ordered ziggy Imps, i wonder what the shipping difference would be? |

Title: Re: IMPERIAL SO PLANS Post by Steve Deckert on 10/28/05 at 17:50:48 The football shape exists for proper clearance at the top edge of the woofer. It also acts as a pre-compression chamber that sets the stage for a good launch of pressure towards the throat of the horn. I could have built the cabinet to where the woofer wouldn't have had clearance issues, but my main concern was balancing and controlling the pressures in front of the cone. Using anything other then the single 15 inch driver would require a complete re-design of this removable front section and likely create significantly more problems then anything else. |

Title: Re: IMPERIAL SO PLANS Post by 60ndown on 10/30/05 at 21:31:03 #^*+*! .........darling..........do you mind if i build a new subwoofer?.... shes gonna kill me............... ::) ;D :'( |

Title: Re: IMPERIAL SO PLANS Post by gexter on 10/30/05 at 22:55:53 I hear ya and I am not even going to try to build one. unless like I said before, my exsiting concept could morph into one in stages. The word driver or speaker are verbotten at the moment. Because I don't want to upset the cart before the WO32 plans arrive. Gex |

Title: Re: IMPERIAL SO PLANS Post by Brian on 11/10/05 at 01:55:14 Great stuff. Thanks for the design Steve. :) |

Title: Re: IMPERIAL SO PLANS Post by selmerdave on 11/11/05 at 16:04:10 What exactly makes it a sub-only, could I not use a single 15" coaxial driver to cover the full range? Dave |
|
Title: Re: IMPERIAL SO PLANS Post by jj420 on 11/11/05 at 19:03:21 Dave the cabinet itself is designed to cut out high frequency reproduction in the horn. The horn itself is a hard thing for the driver to load, so a coax would likely be a waste of time, especially when you consider the amount of air redirected by the front panel, at best it would be very beamy. |

Title: Re: IMPERIAL SO PLANS Post by Corey on 11/11/05 at 21:42:12 Can anybody think of a better Christmas gift than an SO? I like to think back to all the great Christmas presents from when you were a kid. I am sorry but it doesn't get much better then Christmas as a kid. Getting presents, rule! Anyways you take that feeling of anticipation and it is like you are excited because you know you are getting something from Decware. Doesn't matter what. It is from decware so you know it will be good. She doesn't tell what it is though! :D It is the full size blueprint plans for an Imperial SO. You are either exstatic if you really get it or you are curious. Then you build one and when you adjust the volume on your bass amp driving it for the very first time the real meaning of that gift from Decware comes through. You have never loved your wife more! Yup... this is definately a gift that keeps on giving. Corey :) |

Title: Re: IMPERIAL SO PLANS Post by Kim Bay Smidt on 06/04/06 at 09:55:47 Missing distances in the plans... a) For the brace A I need to know the distance from the 0.75" cut at the bottom of the frontplate holding the driver and down to the first sharp bend (upwards in the plans). I'm drawing the Imp SO in 3D using SolidWorks and here I get 4.68" but this look way to long compared to Steves plans. b) I need more information to make the K-slot. The radius and the distance for the short parts (at top, bottom and right). c) The removable frontplate is 37.53 inches wide in the plans. Is this correct as the total width of the cabinet is 37.50? d) Placement of brace E. I need more information to make the brace in the right way or the distance to the back or front (inside measurements.) |

Title: Re: IMPERIAL SO PLANS Post by bassboy on 06/05/06 at 02:41:27 As you may or may not know, these plans are very new and I'm guessing not many people have them yet. Of the people that own SO's, most or all had them built for them. It's probably best to call the bossman, at least then you know the info you get is correct. |

Title: Re: IMPERIAL SO PLANS Post by Kim Bay Smidt on 06/06/06 at 21:09:26 I asked Steve 3 questions in an e-mail and he answered me quickly: Quote:
Upcoming plans! ;D Edited: removed some of the distances from here - buy the plans! |

Title: Re: IMPERIAL SO PLANS Post by bassboy on 06/06/06 at 21:39:16 You were trying to figure it out without plans? Of all the designs available here, that is the LAST one I would try to duplicate without plans. The original 1956 plans might get you close, but I'm guessing not nearly close enough. |

Title: Re: IMPERIAL SO PLANS Post by Lee in Arkansas on 06/06/06 at 21:45:40 I've downloaded the plans from the site. My rendition, from the picture at the beginning of this thread, was scarily close. EDIT-Scarily, per bassboy. Yeah, it checks out at dictionary.com. Unfortunately, scaringly does not. I could have sworn that was a word. :-[ EDIT(again)- I don't care what you call me. My name is Leland. I've been called Lee(most often ;)), Kiddo(family :)), Neo(wore a trenchcoat to school after Columbine, just to see what the staff would do :-*), Jet-Lee(friends, for my extensive martial arts background :P), Ben(more friends, because they thought Leland sounded weird ::)), and Redneck(friends, because I've always been the redneck looking/acting/engineering one in the group, then I moved to Arkansas :D). |

Title: Re: IMPERIAL SO PLANS Post by bassboy on 06/06/06 at 21:59:25 LOL, you crack me up too, Jet. You don't mind if I call you Jet, do you? Anyway there are some grammar issues too, not just the spelling of "ahve". Next time try "scarily", although I'm not sure that's a proper word. To be safe, "alarmingly, disconcertingly, shockingly" all fit the bill. |

Yes, it's pretty complex task to duplicate without plans so I do it WITH plans. ;D I'm drawing the speaker in 3D in SolidWorks to get more detailed plans. Furthermore I need to translate inches to metric as I'm living in Europe. ??? I'll send my work to Steve for free. Now I'm just waiting for the release of the Nibbelin NFX plans. :D |
|
Title: Re: IMPERIAL SO PLANS Post by J_Rock on 06/06/06 at 22:07:08 Kim is absolutely right, those dimensions he was asking about aren't on the plans directly, and would require some complex maths to solve anyways. |
|
Title: Re: IMPERIAL SO PLANS Post by Lee in Arkansas on 06/07/06 at 02:04:59 Kim, you do know that you can set SolidWorks to use inches, right? That seems like quite an undertaking, I think I might give a shot, for the hell of it. |
|
Title: Re: IMPERIAL SO PLANS Post by J_Rock on 06/07/06 at 03:16:00 I think he means, model it in inches using the dimensioned drawings, then use solidworks to convert everything and give him more detailed drawings. |
|
Title: Re: IMPERIAL SO PLANS Post by Lee in Arkansas on 06/07/06 at 04:16:28 Well, what you can do in SolidWorks (one of my side jobs is 75% SolidWorks, 25%AutoCAD), is design it in SolidWorks all in inches, then change the setting to metric and rebuild it. It converts all the measurements right there on the spot for you. Really awesome when you have it drawn out in the drawings. BTW-I love this program. |

Exactly what I'm doing. ;D It's pretty hard to get plywood in Europe 0.75" thick so I also need to change thickness (20 mm ~ 0,787"). |

Title: Re: IMPERIAL SO PLANS Post by Gex on 06/07/06 at 11:06:35 Hey Jet/lee whatever. As you get older you take a little ribbing with a little more grace. I am kinda old, likely over twice your age and you would never know it to meet me. You got nothing to prove to me. If I correct your spelling feel free to get me back. You can go all bruce lee or all Mr engineer on me,but your just a fella called jet to me :) we are all in the same game. My SO guess was also close enough to work as well and it used the corner horn dimensions. BTW I will check out that program so thanks :) |

Title: Re: IMPERIAL SO PLANS Post by Lee in Arkansas on 06/07/06 at 13:09:15 ribbing? where? I'm hungry........ I've got a ...ahem... special copy of SolidWorks 2005 with Cosmos. :P Just drop me a line. :-* |
|
Title: Re: IMPERIAL SO PLANS Post by bassboy on 06/07/06 at 17:10:47 Jet knows I'm just kidding - or at least he should know I'm just kidding. I'm not any better, if you look at some of the gobledegook I've typed in haste. I was just referencing the "ahve" joke from the previous day. |

Title: Re: IMPERIAL SO PLANS Post by Gex on 06/07/06 at 17:14:25 MMMMMMM ribs now I am hungry! ;D ;D ;D ;D Ya bassboy its all in fun until someone loses an eye! ::) ( snicker ) :) |

Title: Re: IMPERIAL SO PLANS Post by bassboy on 06/07/06 at 17:52:08 I promise to leave his eyes alone. |

Title: Re: IMPERIAL SO PLANS Post by Lee in Arkansas on 06/07/06 at 18:55:36 Yeah, I caught it, and just played. one eyed fun? That reminds me of a baaaaad joke....lemme find the link. EDIT-I think this is the correct link, but I'm firewalled from the site, so I cannot verify. EDIT(again)-Yup, that's it. Be warned, it's really baaad. :P |

Title: Re: IMPERIAL SO PLANS Post by boydon_lepasci on 06/08/06 at 04:51:41 Just a twist on an oooold gem I know. The way I heard it, the guy knows what he's getting but can't afford better. He's so happy with the results that he promises to return when he has more money. Her reply is, "I'll keep an eye out for you". |
