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/Galerien/Hinkelsteine/slides/Hinkelsteine136.jpg and this http://www.miwis-bastelbu.de/Galerien/Leistungsdruck/slides/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

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/showdetl.cfm?&Partnumber=294-410
JBL 2370A 1" Flat-Front Bi-Radial Horn 90x40 (US($155)
http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=294-420

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

thanks to all

@ 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.

Hello Heiner.
What type of bassdesign do you want to use ?
When you want to go all the way from maybe 30-40Hz to 400-700Hz with one single way, you probably got a vented encloseure (maybe with a short midbass frontloaded horn) in mind ?
1*15 will work, 2*12 with the right choice of drivers will probably work better.
My experiences:
In most cases it´s difficult to force a basdriver to deliver quite deep bassresponse + to have a midbass/midrange (which can keep up with the horns) at the same time.

Trying to get as much surface+bl (for example your 2*12) for the bass can be a quite good way. The suggested Beyma115 has a rather high MMS with 130gr. It will work up to 700Hz, maybe even quite good.
But I think there are other 15´´ drivers that are worth a look, too.(BD15, PA-15-2, TAD160x just to mention a few)

My 15+BMS4590 system (with the Beyma 15LX60, crossover @400Hz) works quite good, but when you compare it to the 18+4*10+BMS4590 system, there is a difference in the "attack" of the upper bass/low mid that makes the crossing to the horns outstanding with the 4*10.
I will try a 15+2*12+BMS4590 soon (currently under construction).

Maybe it´s easier for your bass, when you try to get the crossoverpoint a bit down from the mentioned 700Hz.

It´s like real life: You can´t have it all.
Or like they say in germany: There is no "eierlegendewollmichsau"

🙄


Best regards, Michael

try to specify the project

I am with horns now for some 10 years. I try to attach a picture of my speakers.
they are using:
TAD TD-2001 for the highs
TAD TD-4001 for the mids
Community M4 for the lower mids
6* 9" speakers for the bass
Yes the bass could be better. I tried a lot with different drivers such as BC 1", JBL 2440 2", JBL 435 HPL 1.5", I dont kow the englsh word, but "ionic tweeters" I tried as well.
I am satisfied with the result now.
An externally hosted image should be here but it was not working when we last tested it.

But a friend of mine, who likes the sound of my stereo thinks this is too big for his living room and asked me to buid something smaller. So now I would like to use the BC 1", BR wiht 2 12" per side. I have not decided the brand for this bass by now and I am searching for a good sounding 2" compression driver.
This is why I am looking for 2" drivers. They shouldnot cost much more around 500.-€ or $500.
And I do not know what sound good (neutral) in this pricing.
I would like to use the 2" driver from as low as possible (with a still flat frequency response) up to about 4kHz.
Again thanks to all and please do ot look at the bad english.
Best regards
Heiner

Very nice Michael.
I've checked out your site and enjoyed looking at the pix and am interested in learning more about your system; I can't read German.
Is there a thread on them here?

I'm a long time user and fan of the 4590/2 and may incorporate them into my new system that has just started construction. I am still negotiating with a guy here to turn up the flares for me.

The aesthetics are very striking.

"I would like to use the 2" driver from as low as possible (with a still flat frequency response) up to about 4kHz."

Why not use the 2" driver from the Avantgarde Trio?

It's the CLS M200A, and has a very smooth roll-off beyond 4Khz, and goes to 400hz (on an appropriately sized horn). The retail price is about $400, and mail-order is about $300.
