They require PA amplifier which I believe has a higher voltage output.

Oops!  Forgot....if using normal amp, I believe can bypass the transformer.  Does the driver have any crossover components?

There no cross over

I had try connecting it direct to my audiolab intergrate 8000a.

it work however it was seriously underpower and sound very soft

and nope i didn't see any crossover at the back. it was just the driver itself with the  + and - ve cable feeding thru the miniture transformer seen abv.

yup, the transformer kinda stepdown the higher signal (V) transmission which the PA systems use because of the long length of cabling thru the building.  since u r using non-PA amp, can bypass it

P A speakers work off a 70V or 100V line from a PA amplifier. You should see either a 70V or 100V label on one side of the transformer. On the other side, there should be a 4 or 8 ohms marking with  two wires soldered to the speaker. If it is marked 4 ohms, then the speaker is a 4 ohms speaker...

 

Disconnect the wires connecting the transformer to the speaker terminals and connect the speaker terminals directly to your home amplifier. PA ceiling speakers are normally rated at 3, 6 or 10 watts, but they are usually higher efficiency (SPL) speakers.
