Hello everyone. I write this topic to ask for some help in this area. There are so many tweeters out there and which ones match a paper woofer? I am building a pair of speakers for a friend of mine. So The tweeter's will come in at 4,000 HZ all the way up past my hearing. I know the air ribbons ( like golden ear speakers are nice) but am looking for a tweeter that can play all kinds of music no matter what it is and it's enjoyable. The budget is $200.00 on down for a pair of tweeters. So if anyone would like to help me that would be super I need it. Thanks Jeff

A paper one, seriously. Unfortunately, unless you can score some vintage Bozak, Altec [CTS] or similar, I doubt there's anything other than cheap junk available; plus, without an impedance matching amp, these won't play out to anywhere near 20 kHz at any useful output due to their acoustically large size.

All things considered then, some of the modern 3/4" mobile audio units is where I'd start my research.

Yes seriously a paper woofer. I got them as a gift from a friend. So not a paper tweeter but a tweeter that will go well with or blend well with a paper woofer. Also this is a 8 ohm woofer and is for home audio use. Also these drivers are $250.00 dollars each so I doubt they are far from junk. Jeff

I think the most important decision for you would be the crossover. People use all different kinds of tweets with paper cone mids/woofers with good results. Check the Zaph audio tweeter mishmash for a place to start. PE has a well respected Vifa xt25 on sale right now. The SB acoustics one that's about $50 at madisound is pretty well regarded. Figure out what the woofer is capable of on the top end and select a quality tweet from there that will minimize crossover complexity.

This is all I need and pointing me in the right path. I will go back to John at zaph audio and review there. Then look around on the P.E. Forum. Thanks for your help. Jeff

I like the Dayton Audio RS-28A. It happens to be on sale now at PE. I've heard a few different tweeters and won't speak poorly about any, but I will speak highly of the RS-28A. My hearing is lacking in the upper range, but this guy still comes through and is very pleasing to my ears.

Okay sounds good. I will also look into this tweeter as well. Thanks Jeff
 
I'm just having a bit of fun here. :)

Mr. Joachim Gerhard is one of the finest thinkers in the World on speakers IMO.

Below is his Sonics Arkadia speaker. SEAS CA22RNX and some £30 SEAS 27mm tweeter. Simple second-order crossover. Reflex around 35L and 2.5kHz crossover.

I do stuff like this too, with £6 Monacor HT-22 tweeters. Why pay more?

Wow nice. I agree but when the drivers are free it's hard to beat? Now the tweeters are a different story I have to pay for them. Jeff
 
Don't laff, but sometimes a thrift shop might have a pair of beater boxes from the 70s with cheap Japanese or even Peerless 2-3" paper cone tweeters - they were often implemented with paper full-range "woofers" with minimalist 1st order XO at 6K or higher.

system7 - as great value as some of the Monacor drivers might be, if I'm not mistaken, they're not easily available in CONA, and international shipping can easily double or triple the landed cost of low priced components, but there are a few in this category to chose from folks like Parts Express

You misunderstood, I mean ideally you need a bone fide paper tweeter and was referring to the likely quality of any currently made paper tweeters, assuming they still do, and why I recommended instead concentrating your search among the small mobile audio offerings, at least initially.

Kind of presumptuous on your part to assume I could possibly know anything about your drivers, don't you think?

Usually with an 8" PA speaker you cross it at 2.5kHz with a bass filter of 2mH series and 10uF shunt.

Then just blend it in with a a 2.5kHz crossover second-order tweeter filter. 3.3uF and 0.3mH usually does it. Plus attenuation. Not rocket science.

Random image of Jeff Parham's 2Pi below. 10" Eminence bass as it goes. I feel a bit naughty posting it. :eek:

You will get a better sounding speaker if you cross over to your woofer before the 45* off-axis response gets below -3dB from the on-axis response. With a 8" driver, that means you should probably be crossing in the neighborhood of 1500Hz no matter what the manufacturer tells you about its upper frequency limit. A 4000Hz xo point is not recommended in this situation.

That means you need a tweeter with a very low Fs or a fairly low Fs and a waveguide. The Dayton RS and one of the SB29 tweeters already mentioned would work. The Vifa's would not.
