New Hi-Res Toys

[fakeout]

Uh, was this project completed?

 

[katopis]

No,but it is going to be.actually I'm a friend of Salas,the speakers are mine,but I have not built the cabinets all these years.the project was forgotten but now is on again.i promise pictures from the building process.

 

[katopis]

Well,after 17 years, finally the project completed.it was a lot of time,I know,but finally the aluminum bliss got very nice cabinets,and a first order crossover.it sounds different than my other speakers,and actually different than any other speakers I have ever heard.the transparency must be heard to be believed.

 

[Salas]

Never too late they say! New old stock project.
Congratulations for completing it in a beautiful way.
The drivers look well preserved.

*FAST/WAW (fullrange or widerange assisted with woofer) wasn't terminology when this project was conceived in 2006. But that's how it is called in DIY parlance today.

Salas,

Get the bass and midTweeter as close as possible.

widerange assisted with woofer

Woofer Assisted Wideband.

Were little closer in the conceptual drawing. With four degrees back tilt too. It materialized so many years later, his cabinet guy could now make it CNC multi-faceted so they changed things like height and driver centers enough. But kept the bass volume original. I was told they crossed at about four hundred Hz first order with thick Mundorf air coil and Clarity cap.

 

[Salas]

I went to listen for a little. They look stunning in real life and replay much information with characteristic ease. Bass is firm. Nice to see an old project being finished.

This is 5°, simialr height.

[Salas]

Yes! With just a bit of delay

 

[Salas]

This is 5°, simialr height

This one as finalized has 3 degrees inclination at the Jordan unit which stands at 892mm height including small rubber feet. The speaker as a whole stands 1040mm tall at the back and 980mm at the front. Slanting for some asymmetry.
50 litres total volume for the 8" Alcone woofer and the 3 litres section for the 2.36" spider-less Jordan. Both types are long obsolete. Between their centres there's 290mm distance. That is about λ/3 for the told 400Hz* crossover frequency.

*Later on I measured the impedance rather showing 300Hz is the crossover frequency they ended up with.

 

[diyiggy]

Try not more than 150 hz if the Jordan can permitt that low cut-off.

Curious why you not chosen the SB23NAC with its ribs ? Very smooth driver (though still suffer from early break-ups... look at H5 too)

 

[Salas]

-SB Acoustics did not exist in 2006 when those drivers were bought. Post#1 is that old.
-This particular Jordan can't follow the Alcone 100W RMS woofer at 150Hz crossover. It would soon get damaged. Has no spider. Little closed box air volume is its only back suspension. Can tune to Fb 100-150Hz. No less. 300Hz crossover would bring the C-C distance within λ/4 as made. That's as far low I would try cross. Possibly with second order high pass for better power handling.

The shape a la Avalon is awesome.

See the very good Parsifal on the pictures. But I was believingvit was the pinched SBAcoustics tweeter... Do you know what this dome is ?

 

[Salas]

That's a Parsifal Encore. Second in line model from the 2000's. Bought used had some issues but he refurbished it. Has a Scanspeak tweeter customized for Verity Audio.
Last in line modern version with pinched dome was the Parsifal Anniversary.

 

[planet10]

How much C-C between bass and midTweeter?

dave

 

[Salas]

290mm 300Hz crossover

 

[planet10]

Close. Quarter wavelength is about 300 Hz, closer than they look.

It is indeed a parcifal encore,the last generation before the parcifal ovation,and has a very good scanspeak tweeter,customized for Verity audio ,as Salas said.
