[QUOTE="afroaudio, post: 684314, member: 15197"] Thanks gents! Seems like "acoustic" open cell foam is not worth spending money on. I have been trying to track down wool felt but what I've found is very thin. I like the sandwiching idea but ultimately seems like not rocket science :) As for bracing yes definitely needed here! Box is 81 x 50 x 31 cm internally (golden ratio) I had planned just 2 shelf type braces, one immediately below the driver and next below the port. Is the spacing critical in terms of trying to not reinforce standing waves? Will also be adding bitumen sheet to deaden large panels as much as possible. [/QUOTE]
