Audio and Power Wiring Diagram
To wire the Paradigm Reference Servo‑15, start by connecting the 24‑V, 5‑A power supply to the X‑30 crossover module’s power terminals. Use a 12‑AWG cable for the power line and a separate 12‑AWG cable for the return to keep noise low. Attach the subwoofer’s power lead to the module’s power output, matching polarity (+ to +, – to –). For audio, connect the left and right channels from the source to the X‑30’s input jacks using balanced XLR or RCA cables. The module’s output feeds the subwoofer’s two voice‑coil inputs; again match polarity; Ground the subwoofer chassis to the module’s ground terminal with a 12‑AWG wire. Keep all cable runs under ten feet to minimize phase shift. The diagram below illustrates the connections: • Power supply → X‑30 power input (24 V, 5 A) • X‑30 power output → Subwoofer power lead • Source audio → X‑30 input jacks (XLR/RCA) • X‑30 output → Subwoofer voice‑coil inputs • Ground wire → Subwoofer chassis and X‑30 ground. Follow the manufacturer’s safety guidelines when handling high‑current connections. After completing the wiring, perform a continuity check on all power and audio connections to ensure no open circuits. Use a multimeter set to the appropriate range to verify that the power supply voltage is present at the module’s input terminals. For audio, confirm that the signal passes through the crossover with minimal distortion. Finally, test the subwoofer at low volume before gradually increasing to full power, monitoring for any abnormal noise or overheating. Check ground.
Installation Instructions
Mount the Servo‑15 on a sturdy shelf or wall bracket, ensuring at least 12 inches clearance from walls. Connect the 24‑V power lead to the X‑30 module, then link the module to the subwoofer. Route audio cables from the source to the module’s inputs. Secure all connections and test at low volume power
Placement and Mounting Guidelines
Place the Paradigm Reference Servo‑15 on a level, vibration‑isolated surface such as a sturdy shelf or wall bracket that can bear its weight. The driver should face the listening area and be at least 12 inches (30 cm) from walls or large objects to avoid bass buildup. Avoid corners, which can amplify low‑frequency resonance.
Mounting steps:
- Fasten the bracket to studs or use heavy‑duty wall anchors rated for the unit’s mass.
- Position the subwoofer on the bracket, orienting the front face toward the main listening zone.
- Connect the 24‑V power lead to the X‑30 crossover module, then link the module to the subwoofer’s power input.
- Run the audio cable from the source to the module’s input, keeping it short and away from power cables to reduce interference.
- Place isolation pads or a dedicated sub‑woofer isolation platform to dampen vibrations.
- Verify all connections, then power on at low volume to confirm proper operation before full‑volume use.
In a living room or home theater, a central location usually gives the most even bass dispersion, but a slightly off‑center position can help mitigate standing waves. Keep at least 6 inches (15 cm) of clearance between the subwoofer’s rear and any wall or obstruction to prevent unwanted pressure buildup.
Ensure the unit is in a well‑ventilated area, away from direct heat sources. The sealed design requires no external enclosure, but allow air circulation by not sealing the cabinet to the wall. Inspect mounting hardware annually and replace any worn screws or brackets as needed.

Cleaning, Calibration, and Common Issues
Cleaning the Paradigm Reference Servo‑15 begins with a dry microfiber cloth to remove surface dust from the sealed enclosure and the front‑firing grill. For deeper grime, use a 50/50 isopropyl solution on a soft brush, avoiding contact with the Kevlar‑fiber cone. After wiping, allow the unit to air‑dry for 10 minutes before reconnecting power.
Calibration follows the manufacturer’s procedure: first, set the gain slider to the midpoint, then adjust the crossover frequency slider to match the desired low‑pass point (typically 80 Hz). Use a calibrated measurement microphone and a test signal (e.g., 20‑Hz sine sweep) to verify the output. If the subwoofer exhibits a phase shift or a dip around 60 Hz, readjust the crossover until the response is flat within ±3 dB.
Common issues include: 1) “Buzz” at low volume—often caused by a loose speaker wire; tighten all connections. 2) “Boom” or excessive low‑frequency output—check the gain slider and reduce it by 1‑2 dB. 3) “Clicking” when turning on—ensure the servo arm is not obstructed; clean the arm’s pivot point. 4) “No sound”—verify that the X‑30 crossover module is powered and the input cable is secure. If problems persist, consult the troubleshooting section of the user manual or contact Paradigm support.
