Subwoofer Placement
The Hardscape subwoofer provides low frequency bass
covering up to 2500 sq. feet or about a 30’ radius.
Whenever possible try to locate it in the middle of the
listening area. The included rubber feet gives you the
flexibilty to place it in many locations by helping level and
stabilize the sub on uneven surfaces.
70V Installation Basics
When installing the sub as 70v, make sure the total tap
setting wattage does NOT exceed 80% of the amp’s rated
power.
Finding the Correct Amp Size
AMP POWER x 80% = SAFE
1000W x 80% = 800W
800W ÷ 200W = 4 Subwoofers
Summary:
If using a 1000 watt per channel amplifier like
the CDi 4000, you can use (4) 200W Hardscape
subwoofers (HS-SUB-12).
