some TAD help needed if possible.

wow... how awesome is this?

Andrew Jones is going to Tokyo, and he's going to try to find out the answer for me while he's there


Sometimes an email and a bit of faith....

Won't the 2 x1601 be a 2.5 way config with the second 1601 only running up to 250 hz or so?

[bottleneck]

heya cooky. Hows things?


nooo, the tn-4 either fires up the woofers in dual parallel, or just 1 x 15".

Hi there, fine thanks and yourself?

Ah ok 2x15 all the way up to Horn.

Feels like there should be a jumper in/out of place somewhere.
You could always buy another pair of 1601's!

hiya,

the jumper thing makes sense. I'm hoping for something like that.

You read my mind ref ''extra pair of 1601's" . . .

As widget says though, with the high price of TAD drivers, I could probably sell the drive units and get some Project Arrays instead if it came to that.

The above actually makes sense - but you know how it is when you make something yourself - it becomes ''your baby'' and you can't stand for it not to be right . . you have to fix it because you made it !

I think Guido has this schematic ..... Drop him a line ... and then there is Mackenzie ! He has more info too !

After further investigation on the Internet I'd have to agree with Mr. Widget.

Btw, would anyone have a location on the internet where info on the TAD drivers can ben found? Years ago one could find this on a separate part of the regular Pioneer site, but the TAD name now seems to be used for a high-end speaker line with small woofers instead of the real TAD stuff.

Oh wait, I found it, seems Google has also "realised" that lot of people did not want to see the new TAD when they were looking for the old:

And here is their new consumer line, but I don't care about these products as they seem to be high end as a lot of other stuff:

That is very nice of him, but then he is one hell of a nice guy.

I think the posts above should answer all of your questions though.

hi Frank, I'm sure you have your reasons, but have you heard them? Holy crap! If I had the means, they'd be on my short list (ok, my list isn't very short)

jumpers or extra terminals makes sense for the TN-4 question.

I'm hoping they will see the thread. . It seems very presumptious of me to message them totally out of the blue.


I googled Project Array 1400's.. £8,500!!! (about $12,000). ooyaaah. Maybe not then!

..nb.. and then his valve pre-amp has just blown up.

Not my day. .

Its not a big issue.

Just pad back the horn 3 db using 10 ohms as a base line to calculate the attenuation.

Failing that buy a couple of 8 ohm L pads from Parts Express.

Somewhere on an old server I modelled the Tad crossover.
The 36 db crossover low pass slope does two jobs. Its steep slope removes the response hash above 650 herts that the Tad cone has and also creates a time domain delay on the woofers to align the woofers and the horn.

Way ahead of JBL crossover network design at the time

Hi Ian

I'll wait to hear what TAD have to say - it would be great if there is a simple jumper or similar. It would be nice to hear the crossover as TAD intended it to be heard.

Incidentally if they can't give me the answer .. then an L-pad will be the most sensible solution.

I notice the 4002's are - 16ohm.

Would using 8 ohm Lpads such as these make any difference?

Or should a 16 ohm Lpad be used?
