The white conduit through the foundation is a
passage for the Geothermal loop to the solar panels. Energy
from the sun not directly converted to electricity can be delivered
to the heat pump. |
These black pipes connect to the 2400' of
Geothermal underground tubing. |
Somewhere below the subfloor will be the dual 18" subwoofer in a 25'
cement enclosure. The tuned port will be external to the
cabinet. I like a subwoofer that extends to very low
frequencies, but not loud bass. |
