What the compatibility check found
Impedance Matching
Caveat⚠ Speaker impedance (4Ω) is below amplifier's minimum rating (6Ω). Risk of amplifier damage. — the amplifier's minimum-impedance spec (6Ω) should be verified, as it may be a nominal rating rather than a true minimum
Use speakers with higher impedance or an amplifier rated for lower impedance loads. Never use speakers below the amplifier's minimum rated impedance.
Power Matching
Pass✓ Amplifier power (120W @ 4Ω) is well-matched for speaker sensitivity (87dB)
