Hi, I have had these 207E sitting around for a while now and like to give them a home. They are Dave's enabled 207E's. What would be the best enclosure for these? I have been looking at the Bruce, Sachiko, Curvy Chang and the Dallas II. Your opinions greatly appreciated. These will be going inside a mid sized room with 7.5 foot ceilings. If I missed an enclosure let me know.
Thanks,
John
Thanks,

Of the designs mentioned Curvy Chang or Bruce would be best, Sachiko & Dallas really are for 206.
You have a low ceiling, what are your other room dimensions?

The main room would be 18'x16'or 5.5 meters by 4.9 meters. Yes they are low ceilings, old house. The Curvy Chang was the first design I was looking at. Ok so which one between the Curvy Chang and the Bruce. I listen to all kinds of music but I listen to Enigma style the most. Relaxing but the bass still hits. Thanks for the suggestions. Also I will probably be running these with 300B amps.

The changs are the second generation of Scott's BVRs, As such they respresent an advancement over the 1st gen Harvey/Iris/Bruce. They are all good sounding and i think we will see the 1st gen live on becaue they can be made curvy. Changs are also much easier to build.
Your room is large enuff that you can listen from far enuff away to get the mouths to blend. The low ceiling may mean some placement work to keep from having too much bass (the idea of raising them up to have equal loading on the 2 mouths is an intriging one)

I have the same question, Bruce or Curvy Chang?
But my room is a bit larger, 6.7 meters by 8.5 meters, & a ceiling height of 3.8 meters.
Hope it's ok that I borrow your thread. 😉

John, with the seating distance a room that size implies, I'd suggest the Half Chang might make the most sense.
The single mouth/vent Brynn is essentially in the same branch of the family tree, and works very well with the FE127E in small rooms.
You'd likely need a greater listening distance than your room can afford for any of the double mouth Spawn family to fully integrate, and don't be surprised that even near field you might find the need for a tweeter with the 207E. (FT17H & single cap for a high enough XO could probably do the trick)

The official line is that Curvy Chang is the better bet, but with everything hifi, other kit & room could skew things.
And for the woodworking masochist curvy Bruce has large appeal.

From personal experience I'd say the Changs, sound good in a variety of rooms and positions, and if you can get the magic triangle set up Wow.
I use a FT17H with the FE207's as do quite a few. There is a thread on crossing it over to the main driver. A lot recommend series resistance or a L-pad, I have found this to tame the FT17H, I have a L-pad that give approx 3dB reduction with a 1.0uf Cap, which after lots of trials gives the best balance for me. I found the FT17H when used with a cap alone sounded very bright, there was a lot of trebble energy, the L-pad calmed that down and gave a much nicer presentation. Cymbols shimmered instead of crashing inside your head.
Another plus for the Changs is there a tad imposing, people tend to notice them (and usually ask "what are those?"), I think in this day and age of speakers the size of cornflake packet and listening to music on a cell phone the sight of real speakers is alien to a lot of people.
And as others have shown they can be impresive (and imposing) beautiful bits of furnitue. (Mine arn't they are grey undercoat, I am getting round to finishing them sooooo...n ish)

I never thought about that. Once I get these made I will try to lift them off the floor so they are equally spaced between the floor and the ceiling. I will report back to let you know what chages that made to the sound.

Is that for the half changs or the full changs? The listening position shoud be about 14' away. They will be on one side of the wall and the couch is on the other.

I was thinking these might need a tweeter and the funny thing is I was looking into the FT17H with the L-pad. I was not sure about the cap. Thanks for the info. Also I like the look of large speakers. There is something about a huge speaker.
I like to thank all you guys for your input. I will go with the curvy changs with a twist. A while back I seen a rendition of the curvy chang with the back curved also. I liked the way that looked. I just hope curving the back will not effect the sound. Let me know what you think.

Your half changs came out great merickrc! Have you since removed the other pair of speakers in the picture next to them?
Great job!

I'm thinking with kerfcore, building Curvey B wouldn't be too bad. The big box curves are simple radius, and the CC is small enough that there might be a fast clever way to build it.
Dave,
Do you have the plans ready for Curvy Bruce? Or a version I can get the basic dimension from.
Thanks,
John

Kerf core really needs a framework to hang off of, it is not stiff enuff for my tastes. Best way to do the outer shell would be layers of thin ply or veneer or even better, build it like a west system canoue out of thin strips of cedar.
