Description
Size of Hole
TruAudio’s ST-SUB-10 and 12 subwoofers are designed to
be water tight with a minimal footprint. They can be
strategically installed in almost any space, delivering
booming sound from a convenient source discreetly
hidden in the landscape. The ST-SUB-10 comes in 4 ohm,
and the ST-SUB-12 comes in either 4 ohm or 70V making
it as versatile as it is powerful Please read the following
manual to ensure the best results. We at TruAudio
appreciate your purchase and wish you years of musical
enjoyment.
We recommend putting gravel at the bottom of the hole to
help with drainage. After placing the Sub in the hole, fill the
edges with dirt (don’t pack the dirt in too tight).
