New Fountek full-range drivers
« on: 25 Oct 2010, 09:34 am »
New to me anyway... noticed these on the Madisound site recently, a 3" available in both 4 and 8 ohm versions

and a 5 inch

I'll be trying the 3".

Can't see the FR on the 3" but the 5" looks very good / balanced.  The price is right so it should be fun.

Hi all.
I usualy try to stay away from any drivers having less than 90DB efficiency.
The 5" only has 85DB/1w/1m you need a good number of watts to drive it.

Hi Guy :) You assume that the goals of a project using these drivers would be the same as your goals - but they are not :)

Yes you are right John,
I was assuming that those drivers would not fit any of my audio projects and that not the right way to post my ideas...
Sorry about that.
Now, that being said : What is the goal of the owner of this little full range driver ?
By the way, I am looking for some good and affordable 8'' full range drivers.
I have now a pair of Audio Nirvana 8'' but I want to up grade. I am more or less allergic to passive and active crossovers.
Any advice ?

I really like my Fostex F200A drivers, especially since they've been ""EnABLed".  Not cheap, but no where near the prices some go for.

Like most here I'm "allergic" to crossovers too, but am willing to live with 1st order or beaming as I'm also "allergic" to whizzers.

Hey Guy, no problem. To me the 3" seems well suited (based on modeling in Unibox) to a small satellite speaker - that's how I'll be trying it anyway. The 5" for something like a small ported bookshelf. I agree with you in principle about high efficiency but there's that trade-off between sensitivity, low end extension, and box size :D

I haven't used an 8" fullrange but the B200 is popular. The newish drivers from Tangband, lessee... W8-1808 or W8-1772 depending on application, have good reports. Parts Express have those but given where you live I wonder if you can get them more directly.

BTW I did find a high-efficiency 5" after you made your comment, it's the one from Supravox. I can't make any sense of it in the models though, perhaps it is designed for use in a back-loaded horn.

Hi all.
Those are the pictures of my first attempt in the wonderful world of full range cross over less drivers.
Nothing extraordinary, but it taught me a lot about full range drivers and despite the fact that the sound coming out of those 115 USD/pair (Price I paid a few years back) is a little or a lot agressive, they have something going for them and that's the details especially with voices and strings instruments.
That first expereince did not cost me much and made me want to go further into more experimentations and that's what I will do soon.
Any suggestion of driver's makes are welcome, but I want to stick to 8" full range drivers.

Drivers arrived today. They're... ah, cute :D They don't look the same as the Madisound pictures, but like this: http://www.europe-audio.com/Product.asp?Product_ID=7930 (not that it matters). Better get some box planning done.

They do a bit... a fair bit smaller though  :lol:  Also, conventional surround (not inverted).

Oh, well I finally got them into a pair of old boxes (took out some TBs). Not bad so far, will get them set up better and let them play for a while.

I don't know about the FR89EX but I just made a pair of 2litre flare-slot ported desktops using the FR88EX which looks a remarkably similar driver - also 3" so perhaps this is of interest.

It sounds excellent, balanced frequency response, good bass for the size of enclosure and driver, no harshness in the high's. They arrived boxed and labelled as 'matched pair' but there were no mounting gaskets included. These speakers are currently being driven from a 1W 6AS7 tube amp and it's proven loud enough so far.

Can someone explain to me how these single driver systems work? Is it: 1) The driver reproduces lows to highs with no crossover and somehow manages to push all the air by itself. Or: 2)Are there actually some type of passive second cone or whatever that gets the high end?? I'm very curious about these and there is no electronics at all?? Is that right, its just amp to speaker to ear??
 Thanks in advance, and I think Teflon's Little Red Riding Hood speakers are very cool looking :thumb: :thumb: :thumb: :thumb: :thumb:

You got it exactly - single cone, amp connected to cone with no cross-over, cone plays to ear. Nothing else going on . The cone is designed to produce the full range of frequencies (hence the name).

How does the speaker stay out of its on way to produce highs and lows at the same time?

For low frequencies the cone moves slowly and for high frequencies it moves quickly -what's to get out of the way ?

Generally, big cones suffer break up modes at high freq, they stop moving as a solid piston and small cones struggle to move enough air for good bass. Extreme excursions could, I suppose, lead to some other problems (doppler?) but I don't drive my speakers too hard. However you look at it, it's still a compromise and not necessarily better than a multi-driver speaker. Nevertheless, many people like full range speakers because of both the simplicity of design and the lack of a cross-over's impacting the sound.
