Foam Acoustic Squares for DIY Sound Booth (Coley Ave Area RG1)

Hi Freeglers,

I'm looking for any spare foam acoustic squares to help me build a folding sound booth for audio recordings. Wedge or pyramid shapes are ideal (see attached examples), but I'm not fussy about colour or brand. If you have any leftover or unused acoustic foam panels, I'd be grateful to give them a new home and put them to good use. Collection can be arranged at your convenience.

Thank you!
