Well, what can I say; it is a LOT of work. The last night I was working up-to 5AM, beefing up the frame, trying different solidifiers and dumper, and evaluating the impact they do. I have fine the mouth of this horn and it is insultingly heavy – two people will not lift it up. Also I found a VERY good configuration for loading the frame. The bottom panels have heavy framing and braising – you can see at the third image. The walls are pretty much 2 ¾” heavily dumped with foam. I think it is more than enough, particularly considering that the bottom of the mouth will be bolted by 6” screws to frame of the house. The side panels have the mosaic structure as I wrote above. The large top side of the horn have ordinary “light” frame and all space is filled with 2” sand. People, the sand dumped Baltic bitch sounds phenomenal – the best almond all materials that I have tried and with lowest resonance. The sand is laid in the space between frame and it covered with thick fabric (thickest 12 ounce tarp from Law’s). The perimeter around the fabric is covered with liquid nails and stapled above. It looks very good and it responses very good. I am very glad with result but it is a lot of work. I am tired like hell and I discovering the fragments of glue on body in the locations that same to mention….
