Hi there,I thought I would share my latest project. I went all in on DIY:ing a pair of M2’s when the parts got available some years back. However, the waveguides didnt work well in my room I tried other waveguides with a more narrow pattern with good effect but they were smaller and I felt they needed a cut off higher than optimal to mate to a 15”. Fast forward a couple of years and the 4367 appears and soon after that some of the horns were available through Speaker Exchange. I managed to get hold of a pair and after evaluating some testboxes I began planning my build. I opted for a slightly higher cabinet to be able to use them without stands, and I also made them somewhat deeper. These two changes increased internal volume which also made it possible for me to seal off the top part behind the horn and make it accessible from the back without sacrificing too much volume for the woofer. This I thought would make it easier to mount the horn and the space could be used for crossovers. At first I wanted to try a passive variant of the 4367 and built the HF crossovers. With the D2 and 4367 horn the measurements are outstanding. However, I’m used to my 2451 with SL dias and like the tone of them so much, so at the moment, they are the ones mounted to the horns. I’d also like to take this opportunity to thank all people on this forum who over the years brought me so much inspiration and shared their knowledge. /Jakob
