Vintage comperrsion drivers vs new

Hi was just thinking about trying some new drivers like maybe BMS or Faital Pro instead of the Altec and JBL drivers ive been using. These newer drivers have extended high frequency over my vintage drivers. Also all my drivers are 1" i have read you lose imaging when you go to a bigger 1.4 or 2" throat just was wondering people opinions on these subjects.

It's impossible to answer you without you being more specific about the drivers, horns, bandwith, room, crossovers, and most of what what your goals are over what you do now. Larger than 1" lose imaging? Nope, they tend not to have as smooth treble and can beam a bit but that's why people use the 1" for treble and the 2" for upper midrange and low treble/ the bigger rxit drivers go lower and typically have better mid band response - but that is a generality too.

I am wanting to replace altec 802 G in a model 19 clone the horns are a 800hz tractrix and the crossover point 1200hz.

The Faital 144 comes to mind here if you can use the larger exit. The response above 7k is questionable though. I like to use them with a treble horn. I have a pair of these and the 806 and like the Faital better. The midrange is excellent. The newer Faital 146 looked to be smoother than the 144 so maybe look at that. Celestion makes some fine 1" drivers but even in 300 Hz tractrix horns they have a hard time getting to 1200. 18 Sound also has some very interesting 1.4" drivers. I have no experience with those though.

I was leaning on the Faital 146 or BMS 1.4" and i alread have a pair of 800hz 1.4"Faital tractrix horns currently i have my Altec 802 G on them they sound great just lack high's wish there was a tried and true way to run a horn tweeter on my Altec model 19's and have them sound good then i could just keep my 802's.

Are you padding down the midband? That will bring up the treble
 
Using them on a constant directivity horn doesn't change things for the better. You would definitely have to correct for the HF response drop.
I have some Faital HF146. Apart from running them in on a small transistor radio I haven't used them so far. But they sounded promising. I use them on 18 Sound XT1464 horns.
I have read somewhere that the difference between Faital HF144 and HF146 would be the smoother frequency response of the later versus the lower distortion of the former.
