Default Paper cone tweeters for paper cone mids?

Has anyone here used paper cone tweeters in a modern "serious" project? Im thinking of trying it with the galaxy 5" pro driver. I have it running wide range form 600hz up and it sounds very nice and cohesive through the whole range.

I dont know if this is because of the lack of crossover or the fact that the same cone is producing highs and mids so that the tone or colour is the same. I figure I should try a paper cone tweeter to get better dispersion and test the theory.

Can anyone recommend a decent one, that is still being produced?

You could try this clone of the so-called phenolic ring cone tweeter, originally built by CTS (now out of business IIRC), and which was used on many different speakers, from budget to nice mid-fi gear, until around the mid 90s or so:

phenolic ring tweeter

This is the "upscale" version of that tweeter, which uses the larger voice coil and heavier magnet. Later versions could also include ferrofluid in the v.c. gap. Too bad this one didn't use the black phenolic ring.

I've heard the original many times at various price points, and even the lesser versions could sound decent, or to put it another way, while they aren't the height of accuracy and resolution they didn't irritate my hearing system like so many inexpensive dome tweeters can (in other words, a sin of omission rather than a sin of commission).

It requires a pro tweeter that's my understanding. The Faital Pro 3FE20 series - 91 dB family is a good bet.

Those FaitalPRO tweeters look like they could make an interesting 2 way, with a big bass driver.

I made a couple pairs of the lil brits linked above. (I added a zobel to the woofer) The paper tweeter is actually pretty nice. Very present, without being irritating. A friend I had over to show them to asked if I was playing specific tracks to show them off -- I was not. I was surprised how good they are. I forget just where they were crossed, highish I think. 1st order.

The only aspect that puts me off on these is their diameter of four inches i.e. don't they exhibit a massive beaming tendency?

When I still owned my pair of original Baby Advents, their 1.75" cone tweeter was pretty directional, though otherwise they were smooth/non-fatiguing.

They're 4" from the outside of the metal frame. From the inside of the suspension the diameter is about 2 and 3/4" -ish.

I came to them from running a pair of 6 1/2" fostex full range, so they don't seem very directional to me. They are more so than a dome, I'm sure. I think I recall the lil brit designer talking about how their directionality lets them integrate better with a high cross on a woofer, as the woofer will be pretty directional by then as well.

I was a little tired of how directional my fostex drivers were. These aren't as bad.

Hi,

For $2 (down from $12) a pop from PE I suspect these are pretty good.
You've got to like the six dimples, at least they are trying ......
Dispersion will be better than a 1" dome ......

What you you need is something good and cheap to go with them e.g:
Aurasound NS525-255-8A 5.25" Paper Cone 8 Ohm: Madisound Speaker Store

rgds, sreten.
