21" superscoop? - see the plans section from the front page. Or do you mean a front loaded horn? The power handling is down to the driver you put into it, rather than the cabinet. ------------- Keep pushing on, things are gonna get better. |

the s fold does give a longer horn path.... lower freq output..... a c fold would not play as low due to the shortend horn path, but sound fuller from 50 to 70 hz.....

Is this just a drawing of a horn there would look nice, or has it been designed to "work", and performe what's possible? I am about to build som 21" subs, and this design has been my favorite so far. I just dont want to end up with two horn which performe at the same level as the pd 1850......... -Thanks

What do we have here? This has not been built but the design is pretty much at a point where next step would be the prototype.   PD.2150 2pi 2,83v  PD.2150 0,5pi 1,41v  input:  file: https://dl.dropboxusercontent.com/u/9726318/flh121/flh121_pd2150.skp" rel="nofollow - https://dl.dropboxusercontent.com/u/9726318/flh121/flh121_pd2150.skp Please note that I am quite conservative with my HR data. If this works like previous designs I have done, the real world frq response should be slightly better than the HR prediction. Horn path needs to be heavily braced. After that I don't see problem with building it out of 18mm. PD.2150 SHOULD fit through the access panel frame, but it has not been tested so this is something to consider. External dimensions are 1200*1200*600mm, so the two sides can be cut out of single 2440*1220mm sheet and when stacking or transporting these boxes would be nicely symmetric. I would love to see this in reality. |

As much as I like the Lab Sub, I don't think it is the box to end all boxes. PD.2150 has around 1.7 times the cone area to start with. And most importantly this was a nice study to work on. Unfortunately I do not have time or funding to develope this. |

Yes but Lab12 has lot more x-max. So displacement is much bigger then on your average 12 inch driver. And it is a proven box. No need for expensive experiments. Edit: Oh and i dont really want to know how much it cost to recone the PD2150.

I was thinking about doing something with the lf21n551, xmax 15mm, BL 39, but the fs is up at 35hz, but actually I was modelling tapped horns, had a look at the orthon horn too. ------------- www.facebook.com/babysoundsystem |

So if there is one design that you happen to really like, there is no point in doing other design exercises? Okay. Btw Lab12: Sd = 506,7 cm^2 Xmax = 13mm 2 * 506,7 * 1,3 = 1317,42 cubic cm PD.2150: Sd = 1698,23 cm^2 Xmax = 10,5mm 1698,23 * 1,05 = 1783,1415 cubic cm There are many, MANY sides to this matter. Lab would be more economical when it comes to drivers and it would be smaller but then again when it comes to horns, smaller does not equal better in every aspect. Ease of build would be one thing to consider also. The displacement of PD.2150 versus two Lab12s is 35% bigger, that should do some difference, as should horn's 10% larger frontal area. But then again the design is not tested so why bother? Please also notice that I do really like the Lab Also it would be interesting to see how a big horn would work with something like 18Sound 21NLW.... |

lf21n551: sd: 1730 xmax 1,5 cm 1730*1,5= 2595 Don't mean to be no commercial, just seems like people on here have their heads turned one way sometimes. Note: this is a neo .which is nice for a 21"! It costs less than 100 euros more than 2150. ------------- www.facebook.com/babysoundsystem |

Throat has ratio of 2.5:1, only thing I'm worried is how big cone will hold up. Carbon fiber reinforced cones should be able to hold it. Other than that, it should work as a horn in general, next step would be prototype. |

pfly I have 2 PD2150's here in the US new in box, and have some spare plywood I can test it in? Would you be willing to share the plans? The only thing that concerns me is, has anyone calculated the pressure on the cone at Xmax at a given power? I know corny question, I'm not horn response savvy as well as understanding the folds. May use 18Sound 21NLW9001 in the future if someone can calculate the rear chamber to accommodate the 18Sound,thanks! ------------- BASS, how low can you go! |

Sketchup file where anyone can find all needed measurements and angles can be found in my post on second page. Not too hard to use the measurement tool and protractor in that free software I'd be delighted to have some real world feedback on this design. tv00 feel free to use whatever good quality, strong motored driver you want. Quickie modelling on the RCF gives roughly same results as PD.2150. |

Nice will u post it? The rcf is not as heavy, I used to have 2 pcs pd.2150 too, but they're gone now. It's good to try new brands in new situations, for instance I found that the new fane 15xs & 12xb sims very well in tapped horns. Apart from cyclops I didn't see much of that. I'm going to try that soon. ------------- www.facebook.com/babysoundsystem |

I just remembered when I started messing around with this idea, the original thought was to take WSX style folding and scale it up with roughly 1220x1220mm side panel surface to make most use of full sheet. I wanted to use letterbox styled throat as in certain way I see it as the purest form of horn loaded bass enclosures. Because 21" driver and somewhat large size, I thought it should go as low as reasonably possible. After fooling around with WSX style folding I decided to approximate other folding schemes. In my eyes, "S folding" will give longer horn as WSX-styled folding and also it has added benefit of having slightly straighter horn path with the first fold being not quite as steep. "C fold" is quite clean and nice design, but for given box size it will almost always give slightly shorter horn than "S fold" will. So in the end the thing ended up looking like 1850/186 horn on steroids with Martin Audio inspired throat. I quite hope someone would have time to see if it is worth something. Even with horn mouth this big I'd estimate that having six of these in single stack would give mouth area big enough to support wavelengths getting closer to 30Hz. I always tend to say that as a rule of thumb with horn subs, you need four two man liftable boxes to have big enough mouth to do the job properly. With horn lengths between 1.6 to 2.2 meters or so, it tends to be like that. With proper 30-35hz horns I think number is preferably six, although with four the results are usually more than satisfactory. |

i would support that numbers. 40hz cutoff -> 4 "normal mouth size" FLH (~25.000 cm²) 30hz cutoff -> 6 "normal mouth size" FLH (~35.000 cm²) |

Let me know if you build one Francis! I have a 21sw1600ND and a friend has two 2150s if you want to test:-) Look at the rcf lf21n551, impressive specs & nice price at teamaudio and around, 18sound is brutal, but more expensive. ------------- www.facebook.com/babysoundsystem |

Bump. Has anyone managed to do anything with this? The horn path should be braced from its whole length, the design is missing some of these braces. |

+@PFLY: Looks Nice & mental to me, except that I'd prefer a "C" type horn like invader or amano horn, can you just turn that hornpath around so that it goes along the back side, then top and behind plate to mouth? + If you can just make it ready for cnc I'll get my friend to work! Whow I can't believe you want to do all this for me  Still considering the LF21N551 Have some beyma 21sw1600 and a 18sound coming. But 18sound are far more expensive than the beyma & rcf, the rcf has sick specs! ------------- www.facebook.com/babysoundsystem |

I see no reason that the whole design should be scrapped and refolded when it hasn't even been tested. I mean, if Pfly wants to do that, that is saintly cool. Frankly, I say trust the chef or go to a different restaurant if you don't dig the recipe. There is precedent for this type of fold working. Sure it could be different. Maybe it could be better. But maybe this is the best way and you are passing it up. |

LOL! I was kind of joking, but it's fun that you answer for them. Horns with no 180 degrees bends should sound better in upper range, especially 180 degrees close to mouth should be bad. This is kind of relevant with a long 21" horn going deep, if you want to cross at 100 or more. ------------- www.facebook.com/babysoundsystem |

I already explained my design goals and thought process few posts earlier. I could design C horn also but I see no point in that. I have also sketched up really smooth looking C, or actually G horn for 18" driver if someone is interested. |
Posted By: tv00
Date Posted: 28 October 2015 at 4:53pm
You're right:
But perhaps you're wrong in this assumption, look at this "C" claims to be more compact than "S": http://forum.speakerplans.com/topic35203_post940849.html#940849 I'm interested in that "G" horn, upscalling is always possible! I'm also interested in this:
Another interesting thing is how the 21" horn compares to the amano horn. ------------- www.facebook.com/babysoundsystem |
Posted By: pfly
Date Posted: 28 October 2015 at 5:06pm
WSX "S" is folded more tightly because rear chamber is on top of horn part. Classic Martin S-bin / 1850/186 folding is longer than WSX horn because the horn goes around the rear chamber, like it does in C horn too. Here is the "G" horn I mentioned. I started this by playing around with same dimensions as the Polar Bear scoop. Then I started focusing on getting as smooth expansion as is reasonably possible, which can be seen from many panels that end with 45 deg cuts. It has the same "problem" as some Mykey's design had, it needs two access panels. Other option would be to make access panels to sides.    |

Nice, wonder ehat Mykey design that is? The design looks really good, the acces patch thing is not that convenient, needs some bracing I'd say, so side panel is probably better, what the thick thing next behind the panel? Also I'd probably make one 45 degree panel at the last bend & cut off the sides to fit wheels. Still noce and not the huge rearchamber of the tapped horn. Do you have drawing with measurements & simulations? What size is it? ------------- www.facebook.com/babysoundsystem |
Posted By: pfly
Date Posted: 28 October 2015 at 7:12pm
|
Simplifying the corner would compromise the design goal of having even semi smooth expansion. Big hatch in the back would have some 10-20cm deep cuts of ply stiffening it from the inside, same with smaller internal hatch. Size is the same as my scoop, the Polar Bear, 1220*636*860 With PD.1850 one watt divided between four boxes in half space, grey line is for two boxes  It doesn't go overly low compared to its size but I'd guess it would be quite clean thing down to 40Hz |

Sorry, I am not getting along with the internet today. I have had people ask me for my designs and then come back and want me to redesign this or that or figure out if another driver works, and it makes me wish I never shared. I was projecting my own issues, and I apologize.

My guess is that his sims are more optimistic, he says he takes ghost / phanthom horn into account, this is also probably the best way to do it, if you imagine a long row of subs. I guess side by side horizontal should load in a way equal to ground? (according to 1pi being like 2 speakers in 2 pi) ------------- www.facebook.com/babysoundsystem |
Posted By: bass*en*mass
Date Posted: 28 October 2015 at 8:58pm
|
excuse me tv00, who accounts for "ghost part" and who doesnt? imo, acoustic horn expansion has not much to do with "Pi". 2pi is halfspace with no boundaries within wavelength right? 1pi is quarterspace/halfspace with solid back/wall larger than wavelength or physical stack size larger than lowest wavelength? side by side/horizontal row shows issues if the array length exceeds the wavelengths, beaming occurs.. unless you curve the lot and stack higher or deeper for more spl |

Date Posted: 28 October 2015 at 9:03pm
|
Many accounts for ghost horn, look at invader thread, so does mykey according to himself. check one box 1 pi is equal to two boxes 2 pi. check My question is if the ghost horn is fully used when stacked mirror horizontal or only in a long line, see? ------------- www.facebook.com/babysoundsystem |
Posted By: bass*en*mass
Date Posted: 28 October 2015 at 9:53pm
|
mirror stacks do have limits as do horizontal lines.. a mirror stack of say 4x4 cabs could lead to full 1pi support up to Fs depending on size a horizontal stack of 16 cabs will cause beaming at shorter bass freq. due to array length exceeding the wavelengths within passband quite easy to simulate nowadays.. |

STRAIGHT KICKS :-) Read about them on his facebook. I was playing around with a similar design with magnet in frontchamber in order to make it less deep and cool more, but this was with 15" drivers and no waste space / extra wood on the sides, outside of the box had hornshape... By the end of the day it became too deep for the subs I have atm. Some day I'd love to build 120x80 cm basshorns for my 24 fane 18-1500s sitting in bph at the momemnt, I'm considering Invaders and cyclops. But also reguar ths have the advantage that they're easily v-stacked for low end extension. But even 80cm depth limits the low end excursion, let's say the horn then gets down to 70cm path: 340m/s / 4x0,7m= 121 hz. Also In the meantime I got 6 pcs mach 15x2, they claim response down to 90hz, but the horn is just 45cm long, which seems a bit odd to me... ------------- www.facebook.com/babysoundsystem |

starts with a 180 yes. nice simple fold. great results. the initial size allowances for this driver when I hit the design phase was 60x60x24. with this fold, I got the length I needed in much smaller outside dims. She's still a big box, but all he pain melts away every time I listen :)

Just curious. Exit S around 8000. What is the horn length on simulation? And Net volume? Have you thought about hybride on same speaker? With similar volume? Wish to hear both  and compare.

| Hey so infra what are the chances of getting the dimensions of these boxes I am willing to try to build a couple. I know this is an older post but my variety of 18s just are not doing it for me... |

| Hey Infra, I know this is an older post but I am interested in building these do you have dimensions on these I am willing to take a shot at seeing what they sound like and weight is no issue. I this is mostly for my personal sick enjoyment. my variety of 18s just are not getting low enough for me. |

Hello there. I been reading up on a 21”folded horn design and your post keeps coming up. Have you built this before. Do you have the plans. I built 2 crewin Vega earthquakes with 18” drivers. They sound great but I want that low low low bass that I have heard at festivals before. Let me know when you can. Thanks. Cheers Marty.

I would be super keen to give this build ago whilst I'm stuck at home would you be able to send me the plans somehow?
Cheers

Oh well indeed. The last active post to this thread was four and a half years ago. Since then almost nothing but people asking for plans, and not one reply to any of them, and yet you're surprised  .------------- It's a difficult choice, would you rather have: A: A vegan son.

Kill boris with base? As In uncut amphetamine sulphate? rather than killing him with room shacking earth quaking bass? I do like the idea of good old boris having a terrible time having just done in six grams of pure speed but the havoc he could bring forth once the paranoia kicks in is unimaginable!

I do love how many new members we get on here asking for plans as they just want to build a ‘couple of horns’ so they can have ‘earth shattering deep bass’, and not realising that although efficient (v-loud) most horns won’t drop low at all unless you have a sodding great stack of them!! … also once they have obtained any plans they are never to be seen again and hence contribute zero to the community!! |

| I love how we live in such a modern world and humanly able to be kind humans to each other but we rather keep shit from each other and when someone asks they are trashed and shit talked. It’s simple. If the plans don’t exist then delete the thread. Instead keep posting shit to a thread that’s been dead for years. TOFTS. |

Might just be a nice chap looking to build some boxes? After all the site is called speaker plans. ------------- www.wedding-production.co.uk www.stage2sound.com |

| Agreed. I have built some of my own in the past and always about sharing. I get it. Time and money invested and no one wants to give anything away for free. But like the last poster said this page is called speaker plans. Not speaker dreams. |

Plenty of people come here and get plans & advice for free, i.e. Jack, he came here a little over a year ago knowing very little, he asked questions without being sarcastic, listened to the advice given, was willing to learn, engaged with others and now has a nice little system. He wasn’t dismissive or rude in his First post on this forum…. An introduction and some manners often gets the desired results. |

The thread is left here so that sensible people will arrive here and read all of the thread before asking - so that they can see when their questions have already been asked; and either answered or ignored. You haven't been shit talked , as you so quaintly put it. It's just been pointed out to you that the thread is an old one with nothing recent that's of any help to you. IF you had bothered to take in all of the thread (maybe 10, 15 minutes of reading) then you would have yourself (and us) time and effort - and with all of the contributions to the discussion and you could have learnt something useful from those contributions. You asked for plans which have not been posted for a speaker which has not been built. ------------- It's a difficult choice, would you rather have: A: A vegan son. B: An OnlyFans daughter |

I'm in the process of designing an 18 inch FLH to replace the SBH (the SBH is a design from the 90s, it was rejiggered to work with 'modern drivers' in like 2007, end result is badly optimised and doesn't work well with actual modern drivers). I have been playing with the idea of designing a 21 inch FLH once I'm finished. A 21 has pretty much no advantage over an 18 in a FLH other than the fact that it can displace more air so can it take more power before it runs out of xmax. I might call it the 'Compensator' because... if you are not trying to compensate for something, why would you build it?? Should I actually design this? Even if it makes no sense, maybe it can be something for people who just want the biggest and baddest horn to waste their money on.

Lost count, of how many times, I've been completely underwhelmed by 21" FLH subs. I guess expecting solid 40hz, from stack of 4x cabs, is unreasonable. What I think would be really clever, is modding Martin WSX design, so it doesn't throw too far, for inside venues. A driver with higher Xmax, High BL, and maybe larger chamber in cab, would not require such a long horn,and possibly such tight throat/compression. ------------- Global Depopulation - Alive and Killing. |
