Hiqphon(Or however you spell it) performance

[mzisserson]

Working on a project... Wide dispersion is the requirement. No Wave guides, no Ribbons, AMT's etc.

This limits to a 3/4" dome. Due to a constraint on the midrange, the tweeter must be able to cross over at 2500-2750. 3rd order. I would like to keep the crossover fairly simple (i.e. no notches, shaping filters, etc.).

Target EFF after BSC is going to be in the area of 86dB or so, with the power handling capability/enclsure simulations, etc This speaker should be able to play in the 95-100dB range w/music (before room gains, etc.). Typically it will be used in the 70-75 dB range with a large amp for higher dynamics, however when a little hair is put on it, it needs to hold together. I would like it to do so with the lowerst distortion possible given a tweeter budget of $150ea/less. Music genre can be from metal, to rap, to classical, and jazz....

Will a Hiqphon flavor hold it together in this sort of design? If not, any recommendations of something in the 3/4" format that may and keep up with a low distortion/high performance midbass and 10" woofer of equal caliber?

1" domes will not be concidered.

Thank you.

It's been a few years since I was into speaker building, but I recall the Hiquiphon 0.75" being a very robust tweeter, very musical.

Based on your goals the Hiquphons would be perfect tweeters.

Short and sweet. Thanks Jeff. I know you have used them or at least tested them fairly extensivly. I was looking at the Eton as well, but kept getting pulled back to the HQ's.

The Hiquphons will handle lower frequencies much better than the Etons will. These tweeters were originally designed for Bud Fried who used them with first order series crossovers. They were designed to handle quite a bit of power, low crossovers, and shallow slopes. They are still limited by their size though.

Perfect. Thanks for the history lesson on them. Sounds pretty spot-on then for my application. I am not looking to tear down walls, more the normal moderate listening with the occasional crank-it type. Performance through that range of volume will be critical though.

I need to read-up a little more, but any insight into the advantages/disadvantages between the flavors?

Mike:
There was a recent thread about the Hiq. tweeters and how they compare. Just a few weeks ago. Do a search.

Carl,
This is the internet. Why search when I can ask the same question 1,000 times? :p

Kidding, Thanks, I will take a peek. I was being a bit lazy in all honesty as I said: I have not read much on the different flavors yet. Hope all is well.

All is well Mike and hopefully with you also and into the coming year. Good luck BTW, with the ID competition next weekend!
I Have to admit I was a bit lazy myself in not finding that thread for you and linking it. However, Hiquiphon is a nice word to do a search with because you shouldn't get too many hits. Only the GOOD ones! :0

You might want to look at the Dillon Metaphor's. www.diyspeakers.net/Projects/Dillon/Metaphor.pdf He crossed the OW1 at 2100 with what he called a "transitional 4th to 6th order acoustical slope".

Thanks Ron,

My biggest fear is having to do something outlandish pushing a driver to the edge. For this one if I could not solve it with a fairly traditional constant power set up, I did not want to make it a go. I am not a huge fan of very large values anywhere is a tweeter circuit. It's a 6" mid-range, so it is hard to get a small dome to cross over while maintaining dispersion. I know this "in" crowd is rocking controlled driectivity at the moment but this speaker is meant to have a gigantic sound stage and maintain as wide of dispersion as long as possible. It's all in the design goals of this one, which if I did not have the mids already would use a MTM set-up as the mids with 4" mids.... Would have made life a lot easier. I like the idea of crossing 2.5K or higher anyway, most of the critical midrange which I consider 500Hz-2.5K will be handled by one driver. An option somewhat overlooked now and again in a 3-way set-up.

Controlled directivity and sound stage are not mutually exclusive Mike. And I'm not sure which 3-ways around here overlook the idea of letting a midrange driver handle the bulk of midrange duties.

Still, the systems I've heard using the Hiquphon definitely had a lot going for them. It's a very nice tweeter with great off axis dispersion.

Now that we know the tweeter, what's the 6" mid?

Re: Hiqphon(Or however you spell it) performance

The OWI would be perfect, very robust and "musical" tweeter. Another cheaper alternative often compared to the Hiqs is the Seas 22TAF/G, never heard it myself though.
