Our flat packs are CNC-cut for precision and ease of assembly. Please allow 7–14 days for processing, as each order is custom cut. If you need the subwoofer cutout diameter different than what is mentioned, please leave a note at checkout or send an email immediately after placing order.

We use 13-ply Baltic Birch for durability and quality. Optional terminals are available upon request; however, customers will need to drill their own 5/16” holes for hardware placement based on their specific enclosure design.
