[QUOTE="Papermaker85, post: 8524760, member: 572595"] So I ordered a prototype from SJA in attempt to get more more motor strength and to see if he can do better. Should be here in a few weeks. Very similar design with a custom coil but dual 10" slugs and a huge bumped backplate(same as the apxx). Lower carbon steel 1008 and y35 magnets. Trying right now to restructure the coil former and use slightly smaller spiders to save on the MMS and increase efficiency in the bandwidth. No lie though this current prototype is going to be hard to beat it sounds ******. In doing this to try to keep the product in America and using American coils. I hope this driver is at least as good and in hoping the changes result in a better driver but by no means is the current beast bad. The lowed is controlled and jarring the upper end is good. It has a slow roll off up top but it blends very well and sounds great even crossed a 80. No doubt 1 more spider and the stronger magnets will improve the efficiency but I have to try an American buildhouse out of being a loyal American.. [/QUOTE]
