DIY 3-way horns

[heifisch]

Hello,
I think about a home hifi system. I would like to use 2" compression drivers for the midrange. It should work from 700 HZ to whatever..higher than 4kHz would be nice.
Do you have any recommodations for such a driver?
It should sound "neutral" and must not be toooo expensive.
For Example a TAD TD-4001 would be much to expensive for this application.
Thank you for your ideas.

Since dollar is so weak you can look at JBL 2440/2441 or 375
which can be have for $600-1200 a pair. That's what dr. EDgar is using in his Titan Horns, there are many posts online regarding these speakres or I'd look on German Cesarro line of speakers (they use Tad drivers) for a guideline.

Hallo Heiner,

you could use BMS drivers, since this company has a very good reputation. Its from Niedersachsen

Have a look at this compression driver, the BMS 4592ND. it is coaxial, meaning there are two "drivers" in one unit. you could cross it even lower than you had in mind and it has the advantage of beeing point source all the way from around 500 to 20000hz. additional to that, bms publishes distortion curves of its drivers, which not every company does, which i regard as a big plus.

Hello Heiner,
recently I made myself some speakers with the bms4590 coax driver.
(like this: http://www.miwis-bastelbu.de/Galerie...lsteine136.jpg and this http://www.miwis-bastelbu.de/Galerie...ides/Orn10.jpg )
I´m very surprised about the qualities of the bms (I´ve listend to the TAD 4001, too).
With a big horn and dependig on fitler, the bms can easyly work from 400Hz, delivering more, than your ears will ever stand.

I´m living in Dortmund and I´m faster (haha, still rather slow) with writing in german, than in english.
Feel free to contact me.

Best regards, Michael

Some say the Beyma polyconed CP380M is nice...its only a 1" and recommended fore 1.2khz...but I suppose that fore home use a bit lower should be ok...there is a new neo version too

The CP755 series are said to be ok too, different with hard metal cone...I suppose its a matter of taste...the alu coned might be different too

The popular BMS 2" coax 4592ND is soft coned too, with special ringradiator technology...rather expencive though...BertDoppenberg sells a modified unit

Someone has mentioned something about filling the hollow centerplug with epoxy ?

There is a new BMS 1.4" coax, 4594ND...doesnt seem to peak so much


There is another thread about all this but hasnt been active fore a while

rather expencive though

In germany it´s more expensive compared to the prices in the USA.

But what you get for roundabaout 400 € (4590/4592/4594) ist an absolute bargain in my ears.

Best regards, Michael

Hey Michael,

beautiful speakers you got there

[BlueWizard]

The one thing you need to tell us is exactly what does "must not be toooo expensive" mean? Is that $50 not too expensive or $500 not too expensive.

Is this not too expensive?

4" x 10" Horn Midrange (US$19.60)

Is this not too expensive?

JBL 2426H 1" Titanium Horn Driver 8 Ohm 3-Bolt (US$270)
http://www.partsexpress.com/pe/showd...number=294-410
JBL 2370A 1" Flat-Front Bi-Radial Horn 90x40 (US($155)
http://www.partsexpress.com/pe/showd...number=294-420

We can't possibly answer unless you establish a real framework.

@ limono
I would prefer speakers of current production (but I like the 2440s)
@ Michael really nice speakers, wow
@ Steve
I think about a 1" BC for the highs
the 2" should not cost more than about $500 per driver
and for the bass I am not sure by now. I think about 2 12" per unit or 1 15" driver like the Beyma 115 NDW.
Best regards

There are lots of compression drivers with 2" exits available. Radian, BMS, Beyma, B&C to name a few.
