Ok, perhaps time to start posting.

My first full range project was Konus Essence clone with Jordan JX92S. The sound was pretty good and with small filter planning I could do it even better.

After one year with those I decided to do little modifications because needed something for the bottom end. And so I made Josť speakers, Jordan JX92S with Seas L21RN4X http://koti.kontu.la/jsalonen/cgi/ar...54511127806222 Nice and quite well integrated sound. I was quite happy with these until I got a change to hear french PHY-HP full ranges.

So nowadays my primary system consists of large open baffles with PHY-HP H21 LB 15 SAG elements. The soung is really musical and real, nothing compared to boring hifi. But since my wife thinks the baffles are too big and also ugly I'm planning to do some changes for them. Perhaps have to also think about the possibility to start planning somekind of TL design for them http://koti.kontu.la/jsalonen/cgi/ar...24021143058612

It's rare to see PHY-HP drivers used by "not french" people.

What do you think about them ?

Some say they are ultra-refined and let any detail breath, while some other find the sound couloured, "dark" and very dynamicless, slow and shallow.

Maybe it's stupid suggesting this here, but what about large sealed enclosures, with non-parallel walls, careful damping, ultra-thick walls (or even double-walls with sand in the gap !) ? I think the WAF would definetely be better, and bass extension too

Default FE127E Sealed Bi-pole

Attached is a picture of my most recent pair of speakers. They are a pair of sealed bi-poles (23L) using the Fostex FE127E and built from MDF. Many thanks go out to Mark of www.mach5audio.com who did most of the woodworking. The wife pleaser in the middle is an experiment of his. A 20" sub in an open baffle. See the Mach 5 Audio Testbed for more details.

Initial impressions were very positive. The FE127E goes much higher than we both expected. Good imaging with a very strong mid-range. With the sealed enclosure, you get excellent cone control, great mid-range and the ability to develop moderate to high SPL. The mid-range is much better than that of my BD-Pipes and the FE127E is more extended than the Radio Shack 40-1197.

The test setup was Luxman pre, Beringer DCX, Luxman power. Cross over points between 90 and 120Hz were tried. 90-100Hz worked well with the 20" sub. It was tough trying to place the speakers as we found the 20" sub was often in the way of the music. Very pleased thus far and we expect even better results with a tube amp.

Overall, I am very pleased with the results from this very simple project. I will get a webpage with enclosure plan posted soon.

Cheers,
Gio.

Thanks, I like the long sleek look. I was thinking of painting them a cream/banana color similar to the cone. However, I am open to suggestions. I don't think I am ready to try something like a veneer at this point.

Regards,
Gio.

Actually here in Finland I know 3 persons who have PHY-HP system and I think there are several on top of that.

They really are coloured but in a good way so they really give space to music even if the lowest and highest freqs are not there. The sound is a bit dark but very dynamic, fast and gives really some push to the smallest details.

They are different that's for sure and very sensitive for the amp you're trying to drive them. Also with harder music punk/rock they may sound a bit harsh and thin, with aqoustic, jazz, blues etc the sound is really excellent. Worth of checking out if you are fond of fullrange systems..

I bought some massive wood with thickness of 3cm, from those I'm going to do little front baffles between the current ones and the units. This should increase stiffness under units. We'll see what happens.

OK thanks for the information !

I like the fullrange concept very much though some recent experimenting showed me how better a fullrange driver could work if not used "fullrange" but "extended range", i.E between 150Hz and 6kHz. I think it's the way to go to get big, coherent and refined sound.
