Hi,
I have been offered a pair of hartsfield horn/lens with 2441 drivers. I am thinking of a project to put the hartsfield horn on top of my 4345 and create a 2 way system using active crossover and biamping the 2441 and 2245 only. Crossover frequency would probably be 500-800 hz.
Based on your experience with Hartsfield, Do you think I will get good results from this combination?
Thanks.
What is it you are finding deficient in the stock 4345?

Well, based on my experience, I'd say that you are in for a disappointment .Originally Posted by ngccglp
But apart from my nay-saying, I think you should buy this driver-horn combo & then experiment all you can / it's the best way to learn ( as long as you can afford the tuition fees ) .
So you want to drop the 4-way 4345 and make it 2-way with the 2245 on the lows?
If I were you I'd put the 2441 in the 4345 and use the H93 / 2312 + lens combo like in the 4355.
The 2441 mounted on the 2311 won't clear the dogbox for the 2122. But I agree with that approach. The 2450 will work, and with a dusted diaphragm it is a significant improvement. Imagine what it would be like with Be installed! I also tried some TAD 2001's in mine, and that was very nice. You also might try some new aluminum 2421 diaphragms. I understand what you mean about the midrange CD as is, though.

I've heard the 2-way hartsfield and thought that it was a very different presentation compared to the 4345. Bulk of the difference I think boils down to the HF driver and I am aware of the limited HF extension of the 2441, but there is something special about the 2-way design that is very appealing. There's so much more "texture" to the music compared with the 2421.

Oh yes they will, try harder!!

Not sure how big the 2122H dogbox is but the 2441 fits in my 4343A if you chip off a bit from the top of the dogbox.
Just collected the hartsfield horn/lens with the 2441. The 2441 is a monster! Got to be careful it does not cause any dents on my 4345.
Will borrow a 5235 with 800 hz card tomorrow to experiment. But I think 500 hz would probably be better.
Will post picture soon.
I might have been able to do the same thing, but was reluctant, and because I had the 2450's I never had to make that decision.Oh yes they will, try harder!!

So You want 2245 to push to 500Hz (?), my be too high, or can try with 2242 instead for over 300Hz bass usage.

The tech sheet for 2245 says recommended crossover frequency 800hz. I'm currently using 800 hz card and it sounds quite good. But I want to hear more of the 2441 and think 500 hz is the way to go. Just like hartsfield. Better for the 2245 too.
Hi ngccglp,
You have to be aware of that 2241J has aluminum-diamond-shape diaphragm suspension,
so such combination is fragile for larger diaphragm amplitude, and can be destroyed.
I have done some FR measurements 2241J-AL with 2311 horn (without 2308 lenses)
and it can be seen that under 1200Hz there is not so good. may be 2311 is too small...but...
