Default Woden Vampyr-V

have managed to keep a set of FF105wKeN for our own testing.

Instead of building another set of Fonken (which will happen eventually) it was decided to do another of Scott's designs, Vampyr-V. A development from his Spawn BVR, pushing for results with the small Fostex he came upon the idea of a Big Vent Mass Loaded Voigt. This may be the 1st time this has been done.

I have a gut feeling this design has been under-appreciated and this build is to test that hunch. Originally designed for FE103e then vetted for FE103En, Scott thinks FF105wk will work even better.

Chris has by this time, buttoned up the boxes, here are a couple iPhone snaps -- they will get a coat of clear and then we'll have a listen.

And the drivers that are going in:

Next set of pictures that have escaped from the shop.

Click the image to open in full size.

The supraBaffle with extended trailing edge in place, the fin for mounting the aluminum outriggers that will create a triangular footprint, and a posed view (we'll get a picture with someone standing next to for scale -- after Victor and Maeshowe, these are diminuative)

Chris has gotten a stain to match the driver... it will be interesting to see how the maple takes it.

Chris asks:

I'm second guessing myself on the aesthetics of 3 layers of supra-baffle, whaddya all think of thinning it down to eliminate the flat middle layer so the edge profile will be more continuous?

The big variable radii on the back side looks very nice, but way too much work. Why not cut at 90 degrees and put a 1/4" rad on the exposed bits?

oh, the "fingernail" profile is easy on a router table, or even for that matter by hand - it's the aesthetics - Dave usually leaves those details to the builder, and it turned out clunkier than I thought - looked worse freestanding than on the bench

At the WLs involved, it should be shaped like a Frisbee complete with its ~238? deg edge round over and scalloped rear, at least it's what seemed best overall back when I was testing many different horn mouth terminations, though JMLC's ideal round over may be more mathematically correct, but that would take some careful measurements to confirm and I doubt it would be audible.

Regardless, either would look better/more organic to me.

The deeper it is the better acoustically. If you want to change it out, how about extending it backwards in an ever decreasing "radius" until it peters out near the back leaving a "teardrop" shape?

We've talked about that before - the more I second guess myself on the visual aesthetics, the more paralyzed I become . I think that'd be fine on larger enclosures, but with the scale of this one would destroy its colt-like elegance

Think Reshma Shetty vs Selma Hayek
