Follow Von Hertzog step-by-step as he builds out the SEAS King RO4Y MKIII speaker kit in The Social Club.

FINALLY an in-depth video taking you step-by-step through building the reigning King of all DIY kits, the SEAS King RO4Y MKIII 3-Way Active Speaker Kit. This thing is an absolute game changer. A 10 inch SEAS Extreme 4 ohm aluminum cone subwoofer being fed 250W RMS of clean power from the ncore modules in the state-of-the-art hypex Fusion Amp. With DSP correction and a 32-bit AKM DAC, this kit propels you into the stratosphere of Hifi. The 7 inch midrange and 1 inch tweeter are both made of lacquered aluminum/magnesium contained in one concentric coaxial. These point-source drivers offer holographic imaging and a sweet spot big enough to drive a bus through. These are my brand new studio monitors and I do not see them being dethroned. LONG LIVE THE KING!

One of the design goals of this system is to make the enclosure as small as possible. Since the target group is the DIY enthusiasts the design also required reasonable simplicity.
