With many different produts that I gain an interest in, my next question is how can I build this myself. After I worked in a HIFI store for a few months and spending every day listening to very high end speakers, I wanted to try my hand at designing and building my own.

After gaining some experience with the Cambridge Audio BMR Drivers, I decided to use them for an initial design as I enjoyed their wide dispersion and both the drivers were full range which allowed for a wide variety in choices of crossover frequency and slope.

Unfortunately the 3.5” BMR driver had a strange dip at 2kHz that i wanted to avoid. I decided a 2nd order filter set around 1800Hz would give me the best balance in power handling and phase correctness.

I tend to like the sound of sealed woofer sections with their more natural roll off, especially in a near field situation. I Also experimented with the idea of an open backed tweeter for a more open and lively sound, although this will make room placement more difficult.
