Curvy Chang thread

[vann]

I have just finished reading through the whole thread (that really took some time 🙂).

I'd like to ask an subjective question.
Since I don't have much tools (and even less experience in woodworking), I'm having quite a hard time finding a local workshop that's able to cut the curves of the CC sides (pls don't even ask why).


Q: Is the more focused sound of the Curvy Chang that much better than G Chang, to be worth of all the hustle? Should I just go on and build the G Chang?


As a side note, the room is 5.24meter (17.2 feet) x 6.93meter (22.74 feet), 2.6meter (8.5 feet) high, fairly void of clatter. Sitting/listening place is 8 feet from the loudspeakers (which themselves can be distanced 7 feet apart from each other). Listening place --- loudspeakers line is on the short side of the room.
I remember someone (maybe Ron or Scott) saying that listening distance should be around 11-12 feet from the CC, so the listener can be inside the relatively small focus spot.

I guess as less focused model, G Chang is maybe better suited for my room?


P.S. I know that the drivers are discontinued and thus their BVR builds obsolete, but I already have a pair of FE207E drivers waiting for me to find time and make them a suitable home.

Finally completed my Curvy Changs last night and listened to music for about 4 hours... wow, they are sensational! Now I know what sonic bubble means! 🙂

A big thank you to Dave, Scott and anyone else involved in the design of these cabinets... fantastic work!

Awesome!! You should definitely post some pics. Which driver did you use?

Pioneer bofus with the Dayton tweeters + 2uf caps. Just waiting for some sunny weather and will take some pics.

Did you buy the drivers recently? if so where 🙂

I'm having troubles sourcing some 8" full rangers to go in a curvey chang. As with the fe206ea, I have one source but they want $450 a pair...

SC.

I bought the drivers late 2010 - took a long while to get the cabinets made for me... I bought another pair of bofus from Spectrum Audio in Germany - I think it was their last pair in middle 2011.

A shame these drivers are out of production...

Here are some pics... excuse the warzone, 2 little rascals have taken over dad's rumpus 🙂

Those are certainly shiny... very pretty.

You couldn't get the tweeter closer to the B20?

Hi Dave,

I didnt realise at the time how far the tweeter would be when the design was discussed with the cabinet maker... I should have marked it out. Oh well, they sound fantastic so no complaints here! 🙂

🙂Nice

Thanks marce.

Looking good! 🙂 and good to know that you're enjoying them.

 

[zany]

Thanks zman, my brother and I just had a 5 hour listening session... he kept asking for more cds... 🙂

 

[zman01]

Zany,

Terrific! What genres have you been throwing at them?

 

[zany]

Over the last two days, a variety of music has been played...

Chesky - Ultimate demonstration disc
Linn Selektions SACD
Grover Washington Jr - Jazz moods
Hush Collection Volume 10 - Chamber strings
Sade - Ultimate Collection CD2
Paul Simon - Graceland
Maxwell - Embrya
Foreigner - The Definitive
Massive Attack - Mezzanine
Dire Straits - Love over Gold
Some Deep House mp3 files

want to play some orchestral material next...

 

[talaerts]

Ah, Massive Attack is an interesting choice for a test. How do the first (bass) notes of "Angel" come out?

 

[zany]

starts soft, then comes on stronger with good articulation... nice! 🙂

 

[talaerts]

That's good news. "Angel" is in my opinion a rather difficult track for many speakers.

 

[urmoo]

Zany, what is exact type of your Dayton tweeters? Nice Changs 🙂

 

[zany]

Thanks. I used these...

Dayton Audio ND16FA-6 5/8" Neodymium Dome Tweeter 275-025

but if I was to do it again, I'd probably use their bigger brother with the larger flange.

Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter 275-030

Also has 50% more power handling...
