Over View

These speakers are designed for film and for fun! Keeping aesthetics as the main design goal, their main purpose is for cinema and for the ocasional house party. This led to important design goals that I wanted to keep different then any previous students. This included an acrylic baffle, a visible crossover so that you can see the inner workings of the speaker, and to top it off, LEDs to give it a little more sparkle. The acoustical properties that were my main goals were to have the capability of a wide dynamic range and an extended frequency range through the use of a transmission line.
