Best horns from 2-3 kHz for TAD TD-4001

[pengesluk]

Looking for the best solution for a pair of TAD4001's - operating from 2-3 Khz somwhere, and upwards. ET-703 on top of that.

Any suggestions? Salad bowls? Le Cleach? Full roll-back? Wood? Bill Woods?

Looking for the ultimate in sound rather than efficiency, as it is high enough already

Look into the Le Cleach thread. Plenty of reading there.

what will you be using under that horn?

TAD TM-1201

OK without trying to offend Hornresp militia, you will be wasting TD4001 at 2-3khz cross and small horn IMHO. Bigger the horn -better it sounds, also I like it better with resistive Lpad (an old EV Lpad with quite a bit inductance to kill TADs peaky HF a little). It sounds bad in Salad Bowls (I have Edgar 350Hz) and Dr. Edgar has a theory that TAD 4001 was developed with it's own TH 4001 horn in mind and highly resistive padding to ameliorate it's defficiencies. I would not use it in any Tractrix except 180-250Hz with crossing no more than 7khz. Myself I much preffer JABO KH55a round exponential to Edgar horn.
Look at Cessaro Acoustic , their 4001 horn although tractrix like is at least 250Hz in size. Anyway over 3k you may use it without any horn with open back as a dome midrange....

If used as a direct radiator, the 1201 will be quite beamy: ~70° at 2khz, and ~50° at 3khz (with lobs...), so you are looking for a horn with a narrow dispertion (and the ET703 will be a mismatch).
Also using the 4001 only down to 2/3khz is a bit of a waste, as it will certainly be better than the 1201 in the 1khz-3khz range (lower limit also depending on the horn, of course)

If you choose a 90° horn the 1.5khz would be the maximum crossover point to use.

Why not look for a TH4001 clone and use it down to ~1khz?

Order a pair of LeCleach 200T(Fc=200Hz) from Auto-Tech in Poland. Sensationally low price. Would suit the 4001 extremely good. If going from2-3kHz go for a TD2001 instead.

[limono]

The only problem would be how to integrate 200Hz LeCleach with tweeter and other channels...

Possible solution when baffled:

SEOS waveguide

available in 18, 15, 12 and 10 inches.

Are you shure the TD-4001 sounds better than the TM-1201 below 2-2.500 Hz? I have both here, with TH-4001 also.
