Here is the detail for throat of 110cf tractrix

|

[quote user="anthony"]It is a compression driver with an 8" cone. If you want authority at 300Hz you will need diaphragm area. The Fane Studio 8M that Romy and plenty of others use for 100Hz up to 1kHz is an 8" cone driver on a 4" throat with a clo...

I have also designed my bass horn to operate between 160hz and 600hz and it will use a supravox 285-2000. It is a 110hz cutoff tractrix horn. However I found out that, there is a modified version of this driver that suits my purposes better. It is by...

Here is my response for the Supravox 285-2000 in 110cf tractrix. I designed a sealed chamber and with the qtc 0.707 it is tuned to 160hz. However I hope the modified version will be even better!...

...say like a Supravox at around 99dB: http://www.supravox.fr/mesures/mestg11.htm for some measurements and http://www.supravox.fr/haut_parleurs/tg1.htm for data. They rate it for 98dB but when I heard it, it measured a bit more at over 11k...

Petar, I looked at the "custom" driver you posted the address for. It is interesting to look at, all right, but I am not set up to build drivers from scratch. Since I pretty much have to buy something that is either useable as-is or something that ...

Well, the first hurdle is matching efficiency from a dynamic driver to over-the-top horns like yours; but perhaps for others with somewhat lower efficiency horns...http://www.supravox.fr/anglais/haut_parleurs/285_GMF.htmI have had my eye on this one ...

[quote user="Paul S"]Probably not news, but: http://www.supravox.fr/anglais/haut_parleurs/135_LB.htm Another one that at least looks the part.[/quote] Thanks, Paul. This Supravox 135 LB indeed looks like an interring driver for a project of mine. I h...

What I can say after audition of 2-way system with GPA 288 in 350hz horn and JBL 2453 in 550hz horn is that I like the sound without GPA 288.1-way JBL 2453 sounds terrific and 288 can't match that level.So, driver for 1200hz down is under considerati...

I think, I have an opportunity with the range of drivers I have to end up with 4 channels, because 15" Supravox can go very low and merge with 8" Supravox quite effectively. Here is model in Leap:...

The reason that I built the 6C33C preamp was to explore the 6C33C true musical potential like I did with the 845. Not only did I compare the sound of these tubes in power amp, but also in preamp. The reason is that with power amp you might hit some l...
|
|
Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

Trying to explore the upper bass channel reaching up to a Victor Sierra 360 Hz horn with an Altec 804 with a 4 uF oilcap, I first used my OB Supravox 215, then a B&C 8" woofer in a large BR originally used with EV 15" (the latter not good) ...

Well, I'm still waiting for 2m 40Hz horn, 200Hz and 270Hz LeCleach. But can't wait to try something!But I'm very eager to experiment with drivers I have, so this is what I got today!If someone has expirience in judging recorded sound, welcome to comm...

I did some experiments today again with GOTO in my existing horn and it is obvious for me that I need different horn for GOTO.Existing horn was modelled and designed for Supravox and I see perfect curve with it.But GOTO in it shows same curve for 50-...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

...if you want to use it "pure" as it were, without any in-between equalising. Or you could tailor the amp accordingly. I would see a lowther working well mid-high rather than mid-bass.My experience is limited, however, to EX-4 used with wizzer in a ...

and call me in the morning.So, the idea is simply to not get one's hopes up?While I would certainly take most mid-fi over most hi-fi, I think you know the reasons for that.Well, why not just run this into the ground, see who salutes?Sure you don...

Copper domes???The Lansche is one of the speakers I would like to hear. Is it sonically useful to cross an ionic tweeter at 1.5kHz?Is it true that a RAAL sounds more like an ionic tweeter than like a ribbon?Here is the CSD of the Supravox:...

I think it best you speak to Ralph directly ,he works with these drivers every day.I do recollect that inthe case of the Supravox ,where there are permanent and field coil versions of the same driver,Ralph told me that there wasn't a huge difference ...
|

I understand they still use TAD 703 and 4001. The 11" is from Supravox. No idea about the bass drivers. I liked this Cessaro demo much better than in previous years. ...
