TAD 1201 horn ?

[dede]

Hello,

I've got a pair of tad 1201 waiting to be used between a 1601 and a tad 4001 in iwata 300 horn.

But i'm wonder if i should use them in direct radiation or in a horn. And if so in wich horn ?

Thanks for your input

IMHO, you'd better leave the 1201 for another project, and find a supertweeter for 1601+4001.

I think that 100-130Hz tractrix (can be a squared one) with 4" throat would sound cosiderably /miles better than 1601 in midbass range. I had it in 202Hz Azura horn crossed at 500 to td4001 in Edgar tractrix and it was very good. You will need to address TAD 4001 HF somehow in the future but don't let be talked out of the upperbass/midbass channel. It is the most important channel and if you get it right you'd be ahead of 99% 15"+tuba speakers.
Go to GoodSoundClub - Romy the Cat's Audio Site infamous Romy site and there is a scandinavian's guy midbass project with 1201. Good luck!

PS There is probably only one tweeter which would match TD4001 -ET703
Fostex t500mkII is very sweet sounding and I liked it more than somewhat bland sounding ET703 with JBL driver but didn't have chance to try it with TD4001. Lastly, you have to be sure and honest with yourself that sonics produced by TAD compression drivers are what you're looking for and willing to invest quite a bit money and a lot of time. 1201 is pretty safe bet -it sounds stunning in midbass horn but compression drivers are controversial ,merciless sounding SOBs and I'm putting mine back on the shelf untill I learn how to use them (I have 1201,4001,703 with custom round horn)and find room/house for 6 channel setup!

For your consideration

Yuichi's Audio Lab.

It seems to me that 4001 can handle easy 500-20kHz. I'd stay with the 1601+4001 combo and actually that is what I will build this summer. I'd save 1201 for something else or sell it to buy a supertweeter.

hello,

Thanks for your input. I currently using The tad's in two ways but i found the 1601 à little bit lifeless above 350 hz.

The plan Is indeed to add an et703 asap and a tl-1801 à little bit later when i will be in my new house.

What ti you think of that Horn ?

With that horn you will definitively need a subwoofer. I am not a big fan of mutliways, my preference goes to two ways with maybe a tweeter to add the 'finishing touches'

What cabinet are you using for 1601 and at what frequency are you crossing?

So far The 1601 are in a 130l reflex box.

The crossover is 650 hz 18db

You can, as earlier said, design a midbass horn around 1201. Beware that the published Mmd=5gr is wrong. Should be 52gr!

[pos]

it is 60g

[revintage]

Hey Pos,

Using Thiele Small mathematics, Mmd is 52gr if we assume the rest of the parameters being right!

But it might also be so that you mean Mms=60gr and then this should be about the same as 52gr Mmd.

But if you have measured an actual driver please share.
