Top Ends done! Time to focus on the sub-woofer(s). The 12 inch woofers and tweeters are now migrated into the speaker cases. As expected, the low end cuts off just below 100 Hz. So, the 18 inch sub-woofer is needed. Time to cut this monster down and make a twin! . Notice the console... A lot of changes, there! I'm not quite done, but it is almost done... again.
