Big breakthroughs the past couple of weeks. PJ was over a while back and we experimented to great effect with a little stuffing in the ends of the chambers to reduce a box resonance in the 250Hz range. Yesterday I remounted the woofers with some rubber o-rings, which had a dramatic effect on a little bit of upper midrange shout that I was trying to eliminate.



These speakers are now where I was hoping to get them. Yesterday I ended up listening for several hours, doing that listening to stuff you are familiar with thing, to see what new information the speakers were capable of revealing. A lot! Vocals are now very natural and it's quite easy to pick out how things were mic'd and mixed. I was able to complete a mix I had been working on for a while, that I was struggling a bit with for lack of a good enough point of reference for my changes. With the midrange issues tamed the job became a whole lot easier.



To top off the great week, the next set of prototype cabinets showed up today. Below are pics of one cabinet dry fitted together. The first cabs are made of veneered MDF, these are made of Baltic birch. It will be interesting to see what effect the new material has on the sound. As you can see the new cabs also have a cubbyhole in the bottom for the passive crossover components and a base for stability.
