PA speakers don't need anything exotic.

why do you think like that?

If you wanted a decent sound you would buy decent speakers.

PA speakers are designed for a specific purpose, Hi-Fi isn't one of them.

Any half decent Class AB or Class D amp will suit even the best PA speakers.

For PA speakers you need an amp that can drive difficult load. People usually prefer a high power one, but it doesn't always guarantee a good drive. And power specs is often a lie.

Amplifier with good drive must have paralleled output transistors. Bipolar is better, but there are many cheap/fake bipolars that sound "hard".

If you are after DIY, here at DIYA you can search for "dirty harry" or "NBIP quasi amp" for example. Or find out about "DX amplifier".

the speaker is specified as 101dB/W @ 1m
127dB @ 1m max.

That implies 200W of input, plus an allowance for compression at high power.
3dB of compression is not unknown, so a 400W amp will allow the speaker to reach 127dB @ 1m.

Buy any 400W into 4ohms PA amplifier.

As AndrewT has re-iterated. This is a PA speaker. Any Class AB/B/D/T amp will suit it.

Any cheap 400W amp will do the job.

Cheaper to buy one than to build one for those speakers.
