Four Corner Sound

Note:

Handles and QD Connectors

The Bass50 and Universal Port feature QD Bolts which allow you to quickly attach/detach the handles. We recommend leaving the handles attached during setup to easily lift and move your components.

Step 01:

Prep the Bottom Bass50s

Remove the 4 grille-side feet from the bottom Bass50s.

Replace the hex bolts, leaving the side bolts slightly unscrewed.

Step 02:

Prep the Top Bass50s

Remove all 8 feet from the top Bass50s.

Replace the hex bolts on the grille-side and the sides. Same as with the first Bass50s, leave the side bolts closest to the grille slightly unscrewed.

Set aside the non-grille-side bolts for now, you will use these to attach the M20 Plate in Step 08.

NOTE: you can attach the M20 Plate at this point, but it will make the unit heavier to lift.

Step 03:

Attach Latches to Bass50s

Slide the latches over the loosened side bolts, then tighten the bolts to hold the latches firmly in place.

Step 04:

Place Bass50s On Dolly

Place the bottom Bass50s on the dollies, grille-side up:

• Hook the battery-side feet under the cleats.
• Lower the control-side feet down into thelatches so they lock firmly in-place.

NOTE: make sure the wheels are locked to prevent the dolly from moving during setup.

We recommend facing the control panel away from the crowd for ease of access to wiring and controls and a cleaner look.

Step 06:

Attach Top Universal Ports

Place the top Universal Ports on top of the bottom ports, with the large opening facing up. Make sure the ports’ feet are aligned, then place the Stacking Clamps over the feet and tighten the knobs to secure the ports together.

Step 07:

Attach Top Bass50s

Place the top Bass50s, grille-side down, on top of the stacks, making sure to align the 4 hex bolts with the spacers on the ports.

Connect and tighten the latches to secure the Bass50s to the ports.

Step 08:

Attach M20 Plates

Place the M20 Plates on the Bass50s, making sure to align the bolt holes.

Use the bolts you set aside in Step 02 to secure the plates to the Bass50s.

Step 09:

Attach Speaker Poles

Screw the threaded end of the Trulli Short Speaker Poles into the top of the M20 Plates. Make sure the poles are screwed in all the way and that there is no gap between the bottom of the pole and the top of the plate.

NOTE: you can hang sandbags off the sides of the M20 Plates to add additional weight.

Step 10:

Attach Top Speakers

Place your top speakers on the Speaker Poles, then rotate the tightening ring to secure them in place.

Step 11:

Setup Controller & Source Device

Place your controller/mixer and source device in the area.
