Question Any experiences with Faital 12PR320 : 12" driver for 40-500 Hz

Hello,


For my two (or three) way speaker, I have search for a 12" driver with a sensibility of 95 dB / W / M for a boxe around 100L.

Actually my design is :
- Faital Pro 12PR320, 12" drivers : 0 to 500 Hz inside 110L
- Fostex FE208EZ : 500 Hz to 20 kHz with corrective RLC inside ~8L

I have "found" the Faital Pro 12PR320 drivers, release in 2017, so relatively new. Is there any one tried it ? did you know any review or test ?

Importants datas was for me :
- sensitivity
- Fs : 42 Hz
- Mmms (low mobile stuff) : 51.4 g
- Xmax : 7.37 mm
- Vas : 98.4 L

The link : FaitalPRO | LF Loudspeakers | 12PR320

And the response from the manufacturer :

I have no experience with this driver.

But it simulates really well. I get -3db at 43hz and -5db at 29hz in 108 liters, 8 msec group delay at 40hz, should sound really nice and "tight".
110 liters you say? Did you try crunching the numbers?
What measurements/outer dimensions are you going for?

I would probably settle for somewhere around 200hz xo.

They are great!! I have them and the 15pr400 and both are of great build quality and have great sound. Extended response also helps with crossover design. Cant go wrong with these drivers!

gug42:

I meant: Have you tried simulating some enclosures for them yet?
Would you like to try and understand/learn it yourself, or do you want a finished design for them?

Hello,

@Mctavish : Thank you, great news

@KaffiMann : I'm in the process to learn thing. I have done some simulation, with the help on a local forum here. 94 or 108 L seems good. I have the event and the box sizing.

But .... I can have .... a pair of good old bass drivers WS 33 NG with the boxes for the price of one 12PR320 .... I think to start with thoses WS33NG and in a future build a boxes with 12PR320.

Regards,

the 2 drivers you picked are very different in character.
i love faital drivers, but in your case the 12" faital will not add much to the picture.
i would pick a 12" subwoofer driver under the fostex and cross much lower (~100hz).

if you insist on using a 12" proaudio driver, the only design that makes sense is this:

Please can you tell me more about the character ?

When you speak about tqwt, is it for the faital only ? Or both ?

And sorry I didn't see the relation between tqwt and pro drivers .... Can you enlight me please ?

Nothing wrong with combining the Fostex FE208EZ in a small sealed chamber with the Faital Pro 12PR320 in a larger TL/BR/TQWT solution. The Faital's higher sensitivity can provide some baffle step compensation if crossed higher, or just playing with different order xo slopes can get you there if going for 200hz xo. Combined with a smooth low end roll off it can make for a really nice sounding system.

You just keep on your track gug42, it is a very promising combination of drivers.

The Faitals are amazing and sound so clean. This particular driver and the 15PR400 are some of my favourite. They produce an effortless hi end sound that very few others can! Go with what you originally intended, you wont be sorry!
