Default Tad 4001 , ET-703 integration

Does anybody have an experience with adding ET 703 supertweeter to TAD 4001 mid? Tad 4001 is mounted on 350 hz tractrix. Crossover points,slopes ,padding, parts used etc.
TIA and regards

Default crossover

Hi,
I am using a 4001 and a 703. I tried different crossover frequencies. I started at 7000 Hz and now ended up at 5000 Hz.
I use a Neville-Thiele filter 1st order.
This is a digital filter and has a steep slope. Crossing at 5000HZ means at 2700Hz it has already -40dB. I am using "acourate" a software for making crossovers for up to 5-way speakers and a room correction system is implemented in acourate as well.
I am very pleased with the result.

Have a nice xmas.

Hi Heifish
I thought that you're using TD2001 for a tweeter.
I've got TD4001 , also TM 1201 and ET 703 (all used ) just recently and try to cobble it in a system.
I'd have some questions regarding TD 4001 impedance. My units have ~7 Ohm DCR . According to some it's 8 Ohm driver but others say all 16 Oms TD 4001 measure between 4-8Ohm. J.M Le Cleach posted an impedance graph and it does show that driver impedance in Horn (I think it was TH4001 ) is 16 Ohm at 700 Hz .
I do not want to go into active crossover /multi amp config. I will use K-horns for bass and from 80-100 TM1201 in hypex horn up to 700 Hz.
What was your best sounding passive crossover ?
So far ( since I didn't build midbass horn yet I'm listenning to TD4001 in 350Hz horn crossed at 700Hz to altec 15" (no supertweeter attached) It has a resolution ,detail etc . It is fairly smooth but after 1/2 hour I'm tired of it.
Are you familiar with Cessaro crossover implementation?
Best regards and Happy Holidays as well

Default 4001 703

Hi limono,
for impedance try arta. This is a nice software to measure frequency, impedance and a lot more. It has a very good manual and you can get lots of information how to build your measuring equipment and how to use it. It is not expensive and I think you can use it free, if you do not save your measurements.
If you have a mac, you can use fuzzmeasure for kind of similar things. In the fussmeasure manual is explained how to measure the impedance of a speaker.
Sorry, I have not tried passive crossover with the ET-703. I did a measurement and it goes down to 4000Hz. TAD recommend a 2nd order filter and a cutoff frequency not lower as 5000 Hz.
When I used the 2001 I had a ppassive crossover 1st order at about 4000 Hz. This was nice too, but it is not an easy setup because there are lots of frequencies both units play.
Sorry, I do not know what Cessaro is doing in their crossovers.
Best regards

Hello Heifisch,
I am interested in building up a similar system like you have with a pair of TAD 4002 and ET-703.Unfortunately I donīt have any experience with this driver.Sure they are the top what you can get for money but I think I will struggle with the crossover set up.
I have seen that you are from the Cologne area.I am working on a temporary job here in Cologne.My question would be if it is possible from your side to exchange some information about that or even meet up for a listening test at your place.

Thanks.
Best regards.Alpinerunner

Here is the response graph of the TD-4001 and ET-703.
Perhaps these graphs might give an idea about integrating these two drivers.

Also, in the Exclusive 3401 speakers, the ET-703 is crossed at 7kHz.
