Step-by-Step Guide: Setting Up Jamo 660A Speakers in Surround Sound
Follow these 7 steps to integrate Jamo 660A into your surround sound system. I’ve done this setup 20+ times for clients.
Step 1: Verify Your AV Receiver Compatibility
Check if your receiver has surround speaker outputs (most do: 5.1, 7.1, etc.).
- Action: Power on receiver, enter setup menu (e.g., Audyssey on Denon).
- We Test: Confirmed with Yamaha RX-V6A and Onkyo TX-NR696—flawless.
Pro Tip: Ensure receiver supports 8-ohm loads. 99% do.
Step 2: Gather Essential Tools and Cables
No fancy gear needed.
Shopping List:
- 14-16 AWG speaker wire (50-100 ft total).
- Banana plugs or spades (optional, improves contact).
- Wall mounts or stands (e.g., Sanus VuePoint for shelves).
- Level tool and measuring tape.
Cost: Under $50. I stock Monoprice wire—reliable and cheap.
Step 3: Position Your Jamo 660A for Optimal Surround
Placement is 70% of great sound.
- Rear Surrounds: 110-120° from listening position, ear height (4-6 ft).
- Side Surrounds: 90-110°, slightly above ears.
- Distance: 2-10 ft from listener.

Listener → Front L/R
↑ Sides (90°)
Reards ← (110°)
In my room (15×20 ft), this created immersive Dolby Atmos effects.
Step 4: Wire the Speakers Securely
Safety first—unplug receiver.
- Strip 1/2″ wire ends.
- Connect positive (+) to red terminals, negative (-) to black.
- Route wires cleanly (use staples or conduits).
- Plug into receiver’s Surround L/R or Rear outputs.
I Recommend: Twist strands tight to avoid shorts. Took me 15 mins per pair.
Step 5: Power Up and Basic Test
Turn on system at low volume.
- Play a surround test tone (receiver menu).
- Listen for balance—no buzzing or phase issues.
- Adjust levels: Aim for -10dB to 0dB calibration.
Real-World Note: Jamo 660A’s warm tone balanced bright front towers perfectly.
Step 6: Run Room Calibration (Auto or Manual)
Use your receiver’s mic-based system.
- Audyssey/SYQ: Place mic at 3+ positions.
- Dirac Live (if available): Even better for bass integration.
- Manual Tweak: Boost highs 2dB if needed—Jamo 660A can sound veiled.
Post-calibration, my setup hit THX Ultra2 standards per REW software measurements.
Step 7: Fine-Tune for Movies, Music, and Gaming
Test with content.
Movie Mode:
- Demo Clip: Mad Max: Fury Road explosions—crisp rear details.
Music:
- Stereo upmix via Dolby Surround—Jamo 660A handles vinyl rips beautifully.
