4-way active 15+10+4"horn +tweeter

[cka3o4nuk]

Just finishing my 4 way active setup with FIR filtering.....

sub 30-70hz B&C 15ps100 in TL (labyrinth)
Midbass 70-500hz Beyma 10g40(ported) insane driver best punch i ever get.
Radian 950pb + E-jmlc 300 the midrange is just excellent
Fountek cd 3.5h (don’t sure it is the tweeter will leave)
Clear very detailed sound but too light as i can hear

For sub and mid there are 2 lme49830 with 2sk1530 2sj201 output
for midrange and tweeter - zen4 - with pure film output capacitor

8 channel stepped relay attenuator with additional control of each 2 channels

for now Esi esp1010 for source and Koon fir filters

if somebody can suggest better High-Efficiency tweeter with more bold sound...

thinking about pht-409 to try...

Faital have announced a new bullet tweeter
looks interesting

Good looking project!

You didnt say the crossover freq of the super tweeter. A budget would also be nice to know or i could recommend a GOTO unit

To be honest i would go for one more jmlc horn/driver configuration to reach the top end.

GOTO is too cool for me)
E-jmmlc horns does not reach 20k as i see but i think about them with B&C drivers

The Xo poitns is 70-500-5k for now

 

[Hentai]

Indeed, while 950pb is a wonderful driver, its hard to hit that top end. I meant adding one more horn to your system and one more driver.

I remember a system with 950pd and BMS 4540ND in JMLC horns.
So what i suggest is adding one horn with 1000hz or 2000hz cutoff and a driver like the bms to take the sound from 5k up.

 

[cka3o4nuk]

4540ND

is 1.5inch dome
and it has large distorsion on arount 16k+

dont realy think they will clear enouth on the top end.
just now loking on B&C de7+ejmlc 1400

 

[Hentai]

it has a rise in 2nd harmonic but i wouldnt worry too much about it. In the graph the distortion levels are shifted 10db higher on the scale to fit the graph.

De7 is a good driver but you need a smaller throat on your horn or an adapter and i believe you will have a hard time getting a 1400hz horn with the small throat size.
the bms plays alot higher tho and can be easily equalized to flat response, of course this is just an option.

Meanwhile i found the implementation i was talking about as an example:
6moons industry features: La Grande Castine

e-jmlc 1400 - is 0.75 inch throat
and there is e-jmlc 2000-0.5
the rise of the 2 harmonic indicates the cone breakup

 

[Hentai]

I see, fits like a glove then.

 

[cka3o4nuk]

so there is options)
b&c and e-jmlc which didnt hits 20k strait (bms too dont hit)
or new faital supertweeter) it looks realy nice
ive used beyma cp21f but it too bright because of alluminium diagram
bad that faital is not slot tweeter

 

[WaVeInFoRm]

very nice, box design, the bathroom sinks look quite effective also

infact they are fantasticly formed i must say

 

[cka3o4nuk]

Readed a lot of discussion
as i see now bms 4540 is ring radiator... that changes a lot but ... but in e-jmlc litle too directive and not too smooth
Faital looks better and it is ring radiator too and it smooth but directive
the de7 is just dome but performes incredible smooth in e-jmlc 1400...
so realy only 3 choises hard to decide

 

[lduarte1973]

Nice project but that tweeter desearves it´s own box

 

[cka3o4nuk]

Nice project but that tweeter desearves it´s own box

it will have it when will be desided to left one)

 

[cka3o4nuk]

Still waiting in other suggestions on tweeter candidates

 

[pos]

It much depends on the directivity pattern of your horn at the targeted crossover frequency, that you will want to match to some extend.
Are you happy with the directivity (especially on the vertical axis) of your ribbons?

directivity is acceptible
cant say i happy but the midrange horn is almost the same directivity
the best directivety option is e-jmlc 1400 +b&c de7 but it needs a lot of eq dont shure it will give right sound

 

[pos]

I have used JBL 2407 (exact same driver as the BMS 4540) as a tweeter on a 90°x90° PT waveguide (the one used in the JBL AC16) and got excellent results in term of directivity in the UHF. They are also really easy to eq.

Eny measurment
Horns better that this?

I know Radian 950pb, used it in the past. Its a fine sounding compression driver.
If you look for something better above 1,5khz, use a Beyma TPL-150, and you are done. No compression driver comes even close.
