I've made some small updates that I need to address on the current web site. These are mainly small changes based upon supply of parts, and a couple updates that I've done to help me in small-scale production.
#1. I need to update the crossover picture because I'm using a new P-Core inductor on the woofer. It has a ferrous core, increasing inductance, lowering DCR which gives us maybe 0.5dB more output. I'm not audibly able to tell the difference between the 14AWG air-core, and the 15AWG P-Core. The saturation point is WAY up around 400W or so. The driver would be a crispy-critter way before you hit saturation levels. The cost is no better but I like the way it mounts, and it does give us a little lower DCR so I've moved over to it as my standard for woofer networks where the inductor is in series with the woofer.
#2. I'm now machining the baffles on my CNC mill. I'm able to get exceptionally good tolerances (less than the thickness of the paint) so the drivers drop-in tight. The main advantage, is that I'm now able to mount the drivers without the cut showing at the edges. I also have all the screw-holes exactly lined up to within a couple thousands so the drivers mount perfectly in-line. I was never able to get this level of accuracy manually cutting them so this has been a bonus. It is a small detail but one that has always bothered me when cutting these things manually.
#3. I am FINALLY going to have a demo pair that can rotate around to interested parties. I have a pair of cabinets that have a few cosmetic blems and they are going into demo duty. If you want to give them a listen the cost of admittance, is the shipping price plus everyone pitches in $25 to cover the ultimate cost of the demo pair.
Let me know if you want on the bandwagon.
