Zimmer64, Here's a large Onken enclosure for the 120 (right before trimming the front). This would have as much bass as the tall DBR and you'll get the imaging.

Not sure why the DBR won't image, maybe because the top "box" is so small.

Could be the small Top Box, yes.
The cone is very thin, so I think internal reflections might leak to the outside..

I wonder how a fx120 sounds open baffled ?

It'd need some bass support, maybe even cross it 6db................

The bass is strong anyway, I wish Fostex had supplied plans for a FL - not a DBR.

I don't know Norm, I don't think it what you are looking for.

Imho in an OB it sound very nice!
I tried it with an Xo-point of around 300Hz.

Nice midrange and imaging

An FL?

On the principle that I suspect somebody is going to ask at some point or other:

Left hand column: Fostex design sans damping.
Middle column: Fostex design with damping.
Right hand column: with electrodes attached to testicles, my prefered DBR alignment for the FX120 if a box of roughly similar size is required.

Maybe Doug missed the "T" and hit the "F" my mistake.

an image even a graying balding senior with STML will need some help wiping .... what were you talking about, Kylie you say?



edit:

funny you mentioned the DBR - isn't that where our friend Doug started off, just over a year ago (memory's a bit foggy - must be the Jameson)

Only a year, seems much, much, much longer. Maybe another year I'll comprehend all these acronyms.
