In Practice

• Excellent for medium‑sized rooms, giving both musical and cinematic bass with depth and clarity.

• With a high RMS power rating (1250 W), the 10 Plus is capable of headroom for loud peaks without distortion.

• Very flexible in tuning—it can adapt to different room sizes or speaker systems using the wide adjustable crossovers/phase/polarity.

• The Auto‑EQ / servo control eq suppresses distortion and keeps cone control even at low frequencies and high output.
