Wanting to build a 3-way fully horn-loaded speaker system

[Chamesy]

Hello Everyone. I am wanting to do a DIY 3-way fully horn-loaded speaker build. Was wondering if you guys could teach me some techniques ect to achieve this.

I want the horns to be Tractrix style horns built using MDF or Plywood, around 150w rms output from each speaker and Full-range frequency response from around 100hz-20khz (I will be building a Billfitzmaurice tuba sub eventually). So I need to figure out each drivers needs and how to build a suitable crossover. Ill be powering the speakers with an A-B class reference stereo power Amp then into my computer as I produce music on my computer aswell as listen primarily electronic music and music in general on my computer.

Please help Thanks everyone!

Moved the multi-way since this a 3 way speaker system being discussed.

Budget? Space requirements? Active or passive?

For full-range modified tractrix, you can use one of these...

not too sure on budget, something realistic though. Would like to build them tall enough for average head height or around that. But small enough to fit through doorways easy enough. I tend to prefer passive speakers attached to high power a/b class stereo amplifier. Thank you

Those multiple entry horns are brilliant ! Ide be Happy to build something like that. Add a Tuba HT and ill be in heaven.

This is a great link thank you, Could i make a 3-way or a MTM speaker system with these horns ? and what drivers will i need and where to crossover. maybe it would be good to make active power supplies for each speaker!

This also looks amazing!

Perhaps direct radiator to 250 Hz, then a horn to 1000 Hx and then another horn to cover the rest of the spectrum is a better idea.

Try a double 12 PPSL with a Synergy type horn to the Mid/HF.

I would honestly prefer to build a speaker system up from a subwoofer like the Tuba 60 from the Bill Fitzmaurice designs. Im a horn junky maybe I should stick with Bill Fitmaurice designs if thats the way i wanna go? I would just love to have a nice consistent trumpet looking style.

Hmmm that sounds interest... What are some good PPSL style plans to go for?

Those SYNERGY HORNs are so sexy! Does anyone have plans for mid/hi setup or fullrange ?? Fullrange would be great for studio monitoring!!

Hello DJK.
What would you recommend to rich 300hz in PPSL -10" or 12"?

I bet Martin of Azura would have a zillion good ideas if you contacted him - assuming they are in budget. You could possibly clone a system he has built before / a system owned by one of his other customers.

Red Spade Audio, also in Australia, do a big multiple entry Synergy-style horn (so much so that I assumed it was in copyright violation, until I read that Mr Danley's Unity patents had expired). It costs roughly 6 jillion times as much as the Azura, however. I think the part of my brain that read the price self-cauterised to spare me the pain of knowing.

To DIY more of it / keep to a <$500 horn budget, the Klipsch horn that Cask05 (Chris A) is using would be relatively easy to clone, seeing as much of the expansion is conical.

If I was able to build a (big) listening room around them, I'd make such a clone by starting with the cheap 2" horns from VFM audio* (they have similar throat & coverage angle to the Klipsh), then extend the mouth out to ~1 metre wide - using simple glued-and-screwed ply + filler, sandpaper, then a coat of hammerglaze paint to hide any imperfections. Soffit mount them into room corners and forget about the roundover on the mouth.

*starting with an off-the-shelf horn is cheap, gets the throat right (which is the fiddliest bit), and gets you started, thus prevents the paralysis of too much choice / being in the design phase forever

"What would you recommend to rich 300hz in PPSL -10" or 12"? "

The Dayton 295-120 will do 300hz at 100dB/2.83V/1M and be -3dB at 27hz in a 24" cube PPSL.

I am also designing a 25hz PPSL with eight 8's that will cross at 400hz and be 100dB.

Here is a quad 295-120 PPSL.
