Hi.
Dave, anything on the ft17 and probably the 207 would be great
thanks any version R12 seems the most trustworthy.
Like OzMike I aim to bi-amp with active crossover eventualy.
Still digesting Rons comments, its first thing in the morning, but I think a seperate sub baffle for the ft17 seems the best way initialy, then I can vary the time alingnement.

Marc,

Did you get the files?

If you do a 3D i'd love to get copies.

Hi Dave,
I've got the files thank you.
I've got a basic 3D model built in Autodesk Inventor, but do need to check and alter some dimensions.
Im holiday for the next two weeks, but when I get back I'll sort somthing out, as I can output a variety of formats.
What system are you using?
I am also going to instal the newest version which has some improved rendering tools, which would be fun to play with.
So I must say goodbye to you all for a couple of weeks, hopefully I will be well on the way to finishing a set of Curvey Changs, I cut out a template for 1 side on the CNC machine at work, so the hard part is done.
Had a chat with the misis about them and I think she agreed I could build them, sooo that problems out of the way.

I might ask if I can borrow that template off you Marc when you've finished with it, and assuming it'd be OK for re-use?

marce · 17th August 2007, 09:48 AM

with pleasure.
I was going to use a couple of 8x4 sheets to make a very large router compass, but wouldn't have got the accuracy, plus with the template I can cut both parts of the side in one go.
With this build I am going to
a. document it so with pictures
b. FINISH the cabinets before I put the drivers in them, cos I know if I dont I wont.

I've been down that road a few times myself...

Many thanks Marc -I'll look forward to reading your progress (& using the template when the time comes). If I can help with anything, give me a shout -I'm only about an hour's drive away.

Hi Scott,
almost escaped from work.
I'm looking forward to actually seeing the speakers in the flesh so to speak.
Actualy having a side give more of an impression of what the finished thing will look like. Its hard to find analagies to the impression I got, akin to a large bird of prey sat on a rock waiting to strike. The slim waist and narrow front look quite delicate but the curve looks bigger in the flesh, (and slightly menanacing, like a hooked beak) if you see what I mean.
They will be the sort of thing people are going to walk into a room and see and just go wow.
I'll try and let you all know how its going and depending how far I get I may be back begging advice.
No computer at home at the moment though, kids had an argument over it.

Hi again Scott,
just as a little play last night after a beer or ten and my mind was thinking outside the box (pun inteneded if not funny),
I used to have a Carsboro bass bin, sooo I wondered if it would be possible to combine a curvy chang with a bass bin inside sharing the same mouth flare.
I did some rought sketches and reckon using 8x4 sheets for sides you could get quite a beast. Obviously totaly impractical for normal domestic situations but fun to think about.

Scottmoose · 17th August 2007, 01:20 PM

No theoretical reason why it couldn't be done. Should blow a few eardrums out at any rate.

I'd be interested in getting the drivers into SketchUp. It seems to read a 3D DWG fine.
