Application and Deployment

Stacking, Hanging, and Mounting

Ground stacking CDL Sub18 Subwoofer

• The CDL Sub18 has non-skid rubber feet for applications where the subwoofer is placed on the ground. When stacking another CDL Sub18 atop the CDL Sub18, the feet of the top CDL Sub18 will fit into indentations in the top of the bottom CDL Sub18. This keeps the CDL Sub18 from walking. Provisions should be made to properly secure CDL Sub18s’ when ground stacked.
• Do not stack more than 2 CDL Sub18s.
• Do not attempt to pole mount loudspeakers atop ground-stacked CDL Sub18s.

Hanging a CDL Sub18 Subwoofer

• The CDL Sub18 requires a minimum of four suspension points to be used. Again, select the strongest overhead structure available. The CDL Sub18 can be flown using the four M10 point on the top or the side.
• PreSonus offers an M10 Kit that includes four (4) forged-shoulder steel M10 eyebolts. This kit is to be used with the CDL Sub18 M10 suspension points. These bolts are specifically designed for safe suspension of PreSonus CDL Sub18 subwoofer and must not be substituted. These eyebolts are not a common hardware store item. Please read all included information. A minimum of four (4) eyebolts per CDL Sub18 subwoofer must be used for safe suspension.

Note: When using the M10-Kit, please remember that the eyebolt strength rating will vary with the pull angle. It is extremely important to observe appropriate pull angles when suspending any loudspeaker with eyebolts. Suspending an object with eyebolts should always be done in a way that ensures the resultant forces are within the allowed pull angles.
