Decided to go 12cf sealed... I'm using the SpeakerPower SP2-12000-DP.
Just started my theater build thread over at AVS, but here are the details for my SHS-24 enclosures:
SI SHS-24 Sealed Enclosures (x2):
- Overall Dimensions: 37.75”H x 37.75”W x 21”D
- 12cf internal volume
- 1” MDF double baffle and exterior panels with ¼” rabbets
- ¾” MDF bracing
Thanks for the inspiration @Ricci !
