Santa brought my boys a Nintendo Gamecube for Christmas. The system it's playing on includes some DIY 3-ways with Vifa P17WJ woofers (don't ask why three-way... I had leftover midranges and I wanted to experiment... and yes, the crossovers were a total pain and probably cost more than the drivers). Anyway, the little vented boxes are good to about 55Hz. Does the Gamecube generate low enough information to justify a subwoofer? I'm thinking something in the 60 liter range with a PE plate amp. Suggestions for a not-too-expensive little sub? Thanks "No, boys... trust me... it's simply not possible to connect the Nintendo to the theater system..."
