MTH30 VS CUBO12 VS SB12(beyma)

hi. I;ve built so far MTH30 and Cubo12. It sounds really awesome ! bout of them. MTH is going a lit bit lower.
I am wondering where is the SB12 project from beyma situated ? Is it under cubo12? i am refering at SPL, Extension, etc...
Thanx

The MTH-30 goes deeper then Cubo 12 which goes deeper then the SB12. SPL-wise they're all in the same ball park on average but the frequency characteristcs differ. IIRC Cubo 12 has the highest SPL above 100 Hz-ish, as the MTH30 is flatter, the SB12 has highest SPL above 200 Hz.

Best regards

thanx a lot cubo. Can u tell me how much should i increase the depth and the heigh of the cubo12 if i want to do it as thin as narrow as possible ? thanx a lot !
