Hope you're having (Had?) a good one.
You tried the foam behind the whizzers yet Marc?
tip when cutting it out:
My first set were way too small, you need to make the ID about 4-5mm smaller than the whizzer diameter. Electric carving knife is great for whittling foam into shape. Killed that weird upper-mid out of phase sound when listening off axis. Made a noticeable difference as I fitted them during the Vicar of Dibley final episode.
Next attempt is to slice some foam 5mm thick and bend the ends around and stitch them to make a cylinder.

Hi Mike,
having a good one thanks, hope you are. Spose you just throw an Emu on the barbie for dinner😀 .
Havn't tried the foam yet, hoping now things are returning to normal and I have internet access I can get more focused. My fist hurle must be getting to grips with applying enable, I bought the missis a pair of Tannoy Reveal studio monitors for the bedroom (try as I might I cant convince her that Kimchi Changs would llok nice in the bedroom
They also provide an interesting reference for me to compare the Curvy Changs and any other future designs I try to. One of the biggest differences is listner fatigue, I could (do) listen to the CC's all day, the monitors are initialy exciting but after a while they become tiring. What I am doing is learning to train my ears and become more anylitical, so I can better understand the descriptions of the different nuances in sound that are efected by the mods we do.
Its like the baffle EnABLing I am going to do, I havn't done it sooner as I wanted my ears to become intimately broken in to the sound of the CC's covering a whole spectrum of music so that when I do apply it we will notice the change. i suspect it would be more subtle than cone EnABLing, but as we are becoming more used to hearing that low level detail as a norm, all of us (even the kids) are becoming more intollerent to its lack, or more correctly being hid under a whoosh of low level distortion.
Still learning and having fun doing it.
I have finnaly fought the Vista demon and have sorted out e-mails so will sort everthing out after Christmas.
Have a good holiday All

We're the only country in the world that eats the animals on our coat of arms. Emu, yuck, don't like it much, the meat is really dark, makes beef look like pork. Kangaroo is much nicer.
We had Chicken Pasta, I injured my foot on Christmas eve before I had a chance to get to the shop for some roasting vegetables.
I have a set of Tannoy M15s, I've had them for 15 years now, they are my first proper speakers I bought. They are less fatiguing when well thrashed (broken in) and lifting out the mesh screens over the tweeter domes helped too. I don't know how they make their tweeters these days.

"save a tree, eat a beaver" I remember having a T-shirt with that slogan in my old hippie days John😀 all I can say is the planet is a greener place thanks to my efforts😀 😀
Must say I had Emu recently and liked it, though I am a fan of dark strong meat.
Got the Tannoys second hand, at a very good price, but havn't had much use, so I'll give them a full run in. My reference to listening fatigue is only realy my opinion, as I like the presentation of the Changs and the EnABLed 207's and find listening to them so effortless (and addictive). Though for a good Dance music head banging session the less refined but more forward presentation of the Tannoys is fun. EnABLing the Tannoys should be a good experiment, which I plan to do after I have done my baffles.
Thought I better put a bit of on topic discussion before our carniverous fantasies got out of hand🙂

New Curvy Chang Report
Finally got my Curvy Changs put together!
I'm using a brand new pair of naked FE207Es (no treatment of any kind on the drivers) straight out of the box.
First impression; very dynamic, BIG soundstage, fast and I don't need the sub-woofer anymore. The compound horn design produces a great 'bubble of sound'. It's hard to describe but it adds to the listening experience in a positive way.
One of the things that always amazes me about single driver speakers is how much low end you can get out of them when they are designed properly. This speaker is one of the best single driver speakers I have built and heard. Has very nice balanced, fast and tight low end bass. I haven't measured these yet but they do go low.
They are big. My wife raised an eyebrow when she first walked into the room. But when I laid that big bubble compound horn sound on her she picked out a CD and asked me to play it for her. Haven't heard a word about how they look since.
My build quality on this pair is only fair. These were a fast 'proof of concept' pair of cabs I slapped together rather hastily. And as you can see in the attached picture I'm big on the DIY natural plywood look finish! I'm getting ready to cut wood for a new pair that will be built significantly better and properly finished.
I will also be EnABLing the drivers for the finished pair as well.
Bottom line: Build these! They sound superb.
Scott, Ron and Dave thanks for a great design!!

Glad you like them & you're very welcome.
Also proves a point -big speakers can be domestically acceptable in many cases if you prove to the other party they can significantly enhance their own music.

Hi Ron,
The best way I can describe it is it's like being at a live performance. I can 'feel' the music (I know the objective, measure that for me crowd will love that
!). In a way the sound doesn't seem as directional, meaning ok, I can hear the left speaker over there... it's like the music wraps around you and envelops you. I was listening to Eva Cassidy sing Autum Leaves on her Songbird CD. The experience was like being there, it was very real, made the hair on the back of my neck stand up!
It seems real. Instead of being hit with a wave of sound it's more like being in a bubble of sound. I hope that helps a little. The bottom line is they are a joy to listen to.
[Marce are you hearing anything like I'm hearing?]
Thanks again guys for a great design!

Recurved Chang
How about something like this ? (Not to scale of course)
I find it aesthetically pleasing and a little more sculptural than the base model. Two curves, same front/internal specs. Leave the bottom open or fill it with a sub, looks nice to me 🙂
I'm half way through building a pair of Chilis, when the KimChi plans hit I might try it like my wonderful mspaint diagram and see how it goes.
Oh, no, another pair of speakers to build, ahahaa, the Mrs thinks I'm crazy already.
Cheers,
Sedge.

That would work fine... matter of fact i think i posted soething similar somewhere sometime.
You might not get all that more extension on the bottom given people's comments on the bass and the small volume you have captured with the extension
The extension could be done skeletally with hardwood or aluminium tubing with good effect.

I'm still learning to use plywood and clamps, not MDF and screws. I think Metal would have me tearing out the little hair I have left.
I was thinking of a side firing woofer, IE add a little depth all round, full sides with a laminated back to give me more space for a sealed sub encl. Be tricky to work out the volume though.
Hmmm, I wonder if that curve could be central like a spine and an OB woofer mounted in it ?
Doubt that would work, probably cause some weird issues having an OB woofer mounted 90 degrees and near the wall/floor ? And maye a 12" (should fit OK) OB wouldn't have the output ?
Sadly, I know nothing about OB speakers (or any other speakers for that matter 🙂 ) I'm working on it though.
See what happens after the chilis arrive.
Cheers for the feedback, I'll have a trawl around for your post.

Ah.... OK, just looked Maiko up, right then, sigh, nice 🙂... Deflated, I walk away kicking at stones... Nothing to see here, move along.
I'd want to make those Maiko cabs out of Lexan or something, that Feastrex is a nice looking speaker !

Q to all. I am still throwing around the idea of a pair of CCs. I currently have no clamps big enough. would screw+glue be Ok? I would most likely be using exterior grade ply for reasons of relative cheapness.
Thanks in advance.

Sedge, I find your rendition to be very pleasing to the eye. Artistically it has more ballance and flows with things, bringing the eye away from the unusual height of the cabinet. Your eyes will automatically travel downward and if you place cabinet with the origional version, space them apart and ask anyone which is taller, they will automatically pick the original one.
As for a low end subwoofer built in the cabinet, that is something to ponder. A seperate dedicated subwoofer is far more practical because it can be used with All of your projects, not just this one.
Either way, I really like your drawing.

I think there are several ways of looking at this. The first two are like Amar originally designed for, direct reflecting, and at the opposite end is a single driver focussed. The single driver approach is to have less reflected energy from side walls/floor ect. and the direct reflected is to have more. The major problem with direct reflected is phase/timing issues which no amount of EQ will resolve.
The SD foccused will probably give more of what the recording engineer had in mind due to less room effects. and a single point wide spectrum response.

Re: Recurved Chang
You are correct sir. 😀 What I meant to say is I have not applied any puzzle coat, etc. to the cone or whizzer areas... but I will today!
Sedge, I really like your sculpted idea! I would fill the bottom with sand and not worry about adding a sub... you won't need it in my opinion.
Ron,
I'm not going to say this the right way but the compound horn alignment definitely adds, in a positive way, to the enjoyment of the listening experience. The upper horn area seems to allow sound to come down, around and over you while the lower portion allows the sound to come up and around you at the same time while the integrating the sound from the driver at the same time. It all comes together and creates a most pleasant experience!
In other words I have no idea what the physics are or what else maybe happening. All I know is that I like it... a lot!!
