sICSoundz Posted January 26, 2023 Report Share Posted January 26, 2023 Why a blow thru for 2 12"s especially of that caliber? I am not knocking, Just genuinely curious on what is having you choose that route. With that driver you have the option for either or, so really it would be up to you preference and goals. If you are set on your decision, I'd say without knowing the exact details but more than likely a 4th. "How to build it" Is way to vague. Link to comment Share on other sites More sharing options...
RAMON Heredia MURILLO Posted January 26, 2023 Author Report Share Posted January 26, 2023 We’ll for the meantime I’m sticking with that but I have no space on the inside of my truck and was later planning on upgrading to some other 12s Link to comment Share on other sites More sharing options...
Joe X Posted January 26, 2023 Report Share Posted January 26, 2023 The SDR 12s will work in 4th order bandpass. EBP <70 Suggested box specs for two drivers: Sealed chamber 2.2 net Ported chamber 3.8 net @45Hz Port area 72 square inches. Power to: 1200W RMS.
