I've not tried the Fostex FE103.

IMO a fine driver (I have 4 ~ FE107E the shielded/discontinued

brother).
Smaller drivers and larger ones each have their pros and cons, just have to run the helper woofers a little higher with the little guys.

GR-Research LGK Wedgies

I haven't built the bass sections yet. That will be this winter

Damn Mlundy57. Those look great and without any West Systems epoxy

You've come a long way

Thanks WireNut. Yep, just shellack, no epoxy. I have everything I need to use West systems, just haven't got up the nerve to try any yet. Once I get caught up on build projects I will probably build another test box and experiment with the epoxy. I may even experiment using the epoxy to bond the box sides together.

LX521's, finished and ready to be used (now in use)

WEST Epoxy System can make drop dead pretty complex curve objects. I have seen sailboats and canoes at the same quality as real nice loudspeakers.

I expected to see at least one example of the French PHY-HP speakers set up in the factory recommended cabinet of double-walled construction that is sand filled with folding wings.

People who have actually heard them in the designer's setup said they shook the sand-filled cement block floor of his listening room.

This is a pair a I made, simple 1.5" MDF, sprayed with automotive flat black and the fronts are veneered with Rosewood and finished with Linseed Oil. So everything is very soft. They are heavy. The base is 2.25" thick, the wings/braces are 1.5" thick. I only put the wings/braces on for support, I think it helps in sound improvement, by improving the structures weight a stability.

Those are NICE Bladesmith!
I imagine the wings are functional and also help support the lower bass (Cancellation loss). Almost 1/2 of an "H frame"

Here is my GR-Research Wedgies on top of their GR-Research/Rythmik servo OB bass units (H-Frames). The bass units cover from 20Hz to 200Hz while the Wedgies play from 200Hz to 20kHz. The subs are stereo.

Hi there,

These are my OB, I am using a full range unit of my own design, special designed for OB.. I use a sub for frequency’s below 80 Hz.

I apologize for taking so long to answer your question, don't know how I missed it.

The tweeter is a BG Neo3 PDR planer magnetic (currently unavailable due to sale of BG to Christie Digital).

The midrange drivers are GR-Research LGK's. While actually a full range driver, in this application the LGK's roll off at 200Hz so they perform as midrange drivers. Because of this, a sub unit that can play up to 200Hz is necessary.

Danny Ritchie has recently designed a wedge shaped OB bass unit using three GR-Research/Rythmik 8" servo drivers and an HX300 amp per side. http://www.audiocircle.com/index.php?topic=135399.0 Alternately, you could use two 12" servo drivers and an A370PEQ amp per side for more low end output.

I am currently in the process of building a pair of the wedge bass units with three 8" drivers per side to go with a pair of Wedgies I'm building for someone else.

I wish I could say I built these, but I didn't. I bought these AV123 X-Statik's brand new nearly 8 years ago. Still in absolute mint shape and have been all original this entire time up until just a few days ago when I soldered in the upgraded capacitors and resistors that Danny recommends for these. Definitely worth the $200 investment on that little upgrade.
