I use an FH27 horn, paralleled electrically with an eminence APT80 horn, in their own small enclosure & active line level crossover, I drive them with a 50 watt, @ 4 ohms, PM40c "t amp" (was 2 APT80's, but I broke one).
They are both very good horns in every way, they can (if I want them to), completely overpower my 400 watt PA system, but with active crossover I am in full control of my sound.
The FH27 is certainly a very good horn
For any powerful sound system, but only 25 Watts max = 7.5 volts max, per horn, or kapuut.
thomann carry a massive range of this type of music gear, 3 days delivery, perfect.
