Fellow LH member Steve Gonzales and his wife, were gracious enough to come down to my neck of the woods yesterday to help me out. Steve and I replaced the diaphragms in both motors with the upgraded D16R2421. He also helped me pull the horns out of the cabs, as it's best to have two people doing this (from experience, it is a major beyatch to do it by yourself, removing them is one thing, putting them back is quite another). We had a great time demo'ng the various speaker combo's in the house. Steve had a chance to listen to my roomie's highly modified L-150's and a before/after listen of various tracks on my L-300's. My roommate threatened to laugh loud and long if there wasn't a difference after we replaced the diaphragms. There was a good enough 'diff' that it made it well worth it. Steve's wife Terry (?, hope I'm spelling it right), took many great shots of the whole process and Steve is going to put together an educational thread soon on the diaphragm replacement. Both of them are great people and it was a pleasure spending an afternoon with them! Regarding the photo, Steve is on the left and I'm on the right.
