| The first thing you notice is the front baffle, angled inward at a 45-degree angle. The Prisma is a larger variant on the Rythm Prism design with emphasis on the reverberant field. The Prisma has the following unusual features which make them especially adaptable to a very wide range of rooms:
Radiation Pattern ControlExcellent radiation pattern control, especially considering the width of the footprint. The combination of toe-in and pattern control minimize undesirable very early reflections in a small room and generates a spectrally-correct reverberant field, which is fairly rare outside of a live performance. Room AdaptablePlacement close to a wall, and even in a corner, is feasible thanks to the highly adjustable bass tuning system. Two adjustable-length ports are on the rear panel, one near the top and one near the bottom. Embracing the principle of spreading out the low frequency sources in the room as much as is practical for the sake of smoothness, you can seal the lower port on one speaker and the upper port on the other, resulting in significant staggering of your bass sources from the two speakers in all three dimensions. In a large room where you get less boundary reinforcement, leave both ports open. Adjustable TrebleOn the rear of the speaker is a single external resistor in a terminal cup, and this resistor acts as a high-quality tilt control for the compression driver. Thus the treble balance can be optimized for room acoustics. Dynamic ContrastThe drivers are high quality prosound units that have negligible thermal or mechanical compression in normal home use. This preserves dynamic contrast, which musicians use to convey emotion. Combined with the exceptional radiation pattern control (and a well-engineered crossover), the net result is an outstanding approximation of the timbre, emotion, and overall feeling of a live performance for a 3.3 grand speaker.
