PA midrange for HiFi 3way

[macsaif]

I am building a new Active 3way loudspeakers. The woofer will be Beyma 12LX60V2 in 80l box tuned to 30Hz. I plan to use 18sound 6nd430 as midrange. There are 2 other options:
Beyma 605Nd or 6P200Fe

The inspiration is from
f3b
max

Do you have any experience with these midranges as High end home audio?

As tweeter there are 3 options:
Beyma TPL150
Seas DXT
SS 6600

Do you have any experience with these tweeters?

THX in advance

the 6nd and 6P200 are more alike.. the 605 is a completely different driver (shouldn't extend nearly as low as the other two and requires more from the midbass driver in the lower midrange).

Which design sounded better to you, the f3b or the max?

 

[macsaif]

I have not heard them. Maybe next week there will be a possibility to compare them. There are lot of discussions about PA drivers in home audio however I never had a possibility to compare with hifi drivers.

I've used the B&C 6md38 and the 18sound and preferred the B&C tone. Both were used as midranges in the same system. The B&C was also easier to cross to the tweeter which was 2nd order at 3.5khz. It may have been the high crossover point as the B&C didn't beam as badly which I attributed to the shape of the cone.

woofer Fs is 49hz

I'm not so experienced with vented BR, but is that good

 

[macsaif]

It should be OK. I will use miniDSP crossover and will correct the freq.response from 45 Hz as it is done with F3B.

And what about Usher 8945P?

 

[SpirosZ]

for a midrange at that price range you may want to look at PHL as well

 

[serph1nia]

im experienced with the beyma tweeter, if you have the money, go for it.
Take off the back and cross around 1.5k - 2k

For mids, the 6nd430 open baffle and cross before 2k. 24db/oct

I have the 6nd430 ready to go in a project combined with the beyma tweeter, but I have no experienced with them yet.

Good luck

I would use the 18 Sound 6ND410 or 6NMB420 as they are more suited for midrange use. I have used both and they sound very nice.

The 6ND430 is a great driver which I like to use as well.

And what about Usher 8945P?

Not efficient enough to hang with the Pro audio brethren.

well the audax pr170 is legendary. but I'm not sure what are your crossover points

 

[macsaif]

My crossover points are 250-300Hz and 2-2,2kHz. As i told i will use miniDSP and separate amps it means I am flexible in crossover points and also in efficiency o.f the drivers

 

[Baseballbat]

I can't comment on the midranges as I do not know them, but these two

Seas DXT
SS 6600

will never, in no way, be able to catch up in level with the woofer and midrange. They will, however, work quite well under "home hi-fi" conditions.

You want a good compression driver with a small horn instead. Will be even cheaper than the impressive Beyma TPL.

 

[macsaif]

Can you recommend some good compression driver and horn which are comparable in quality and distortion numbers with SS6600, Millenium, DXT and similar?

 

[SpirosZ]

Some very good choices here for drivers and waveguides.
Final result depends a lot on crossover design though so make sure you know what you are doing.

It seems that they are not shipping to Europe.

It seems that they are not shipping to Europe.

I think they do.
Actually it is only one guy behind this (Eric) and he is doing it in his spare time to help DIYers.
This is from the website "I don't mind shipping to other countries right now. But the site can't figure rates until I get an account set up with the US Postal Service."

I use the audax pr170 crossed around 350hz and 5khz. The sound is sublime. efficiency is 100db. its a incredible driver. It is the best mid I have ever heard.
I use the beyma 12br70 for my bass need, and the two blend seemlessly.
look around for what people think of the audax, thorsten loesch for example, which is a reference in audio thinks highly of this driver...

 

[SpirosZ]

Audax PR170 (MO or NO) is a very hard to find driver.
I was looking into it a few weeks ago and I only found 2 pieces available in Europe at some place after searching the whole internet.
