    Posted: 22 June 2022 at 10:00am
I currently have a unity horn with a 1.4" P-Audio BMD740. It sounds amazing but the compression driver starts distorting before the rest at high volume.

I was wondering how much of an improvement upgrading this would be?

What drivers would you recommend?

The rest of the drivers are faital pro 3" and 6"

Nice looking stack.
What is the crossover frequency for those and what other processing is applied?

Thanks Smile

On the horn it's: 

150 - 510 bass
510 - 1190 mid
1190+ top

On the comp I have this EQ:

1.47khz -4db Q: 1.6
20khz +3db Q: 1.6

I found a post on DIYAudio where someone recorded quite a few compression drivers for comparison.

It sounds like the B&C DE82TN would definitely be a big upgrade so I might go for that.

Has anyone used the DE980TN vs the DE82TN, would it be worth going for that although it is around twice the price?

Edit: the DE980TN isn't in stock. Seems like they are newer and have a better high frequency response so I might go for the DE780TN

The 780TN is comparable to the DE900 regarding its sound characteristic.
DE82TN is also 4.5kg compared to the 980's 2.3kg. If you want something similar to the 980, you could look at the 880. It is basically the same driver, however the 980 has a bigger magnet which gives it a higher efficiency.

Thanks for the reply. I saw the 880 but it is also out of stock on bluearan and estimated 3-5 months.

How is the 780TN compared to the DE82TN in regards to sound?

FaitalPro HF146 is what I put in my unity horns. Doesn't distort at hight volume like the P-Audio driver does - I did try them both. Sure the B&C drivers will be good but I think I chose the Fatial because it had a lower resonance frequency  that didn't interfere with the crossover too badly.

I don't have any experience with the 82TN but do have with the DE800 (which is nice).
In my latest 12" BR +HF I also use de HF146, very nice driver but definitely different due to the diaphragm material.

That is a good shout, I have ordered a HF146.

I think the recommended crossover frequency on the B&C would possibly be a bit high

The driver has arrived today, I will hopefully fit it tomorrow. 

Will see how it does and hopefully post some measurements of it
