Control rooms are the ultimate challenge for any loudspeaker. After getting rid of acoustical flaws and installing a decent power amp it all comes down to the quality of the electro-acoustical transducers.

With nowhere to hide and spotlights all over your body it's difficult to stay calm… But it helps if the designer gave you 30 mm walls, flush mount units and top quality crossover components.

If he also gave you a ribbon mid-high unit your confidence is boosted.

Now you know you will succeed.

Only the biggest control rooms can house shapes like these. So…? Stop mourning and build a bigger control room (reserve space for 3 extra amps).
