Sony Lbtv702 Specs Exclusive May 2026

Core System Specifications

The Sony LBT-V702 is a "pseudo-separate" hi-fi component system from the early 1990s, recognized for its modular stack design and distinctive DBFB (Dynamic Bass Feedback) technology. While it consists of separate units, the system typically uses proprietary ribbon cables for internal power and communication, with the main AC power cord often originating from the tuner.

• Dimensions (Main Unit): 16.5" (W) x 12.8" (H) x 13.4" (D) / 420 x 325 x 340 mm
• Dimensions (Speakers): 9.8" (W) x 15.7" (H) x 10.6" (D) / 250 x 400 x 270 mm
• Weight (Amplifier): 11.5 lbs (5.2 kg)
• Weight (Speakers): 11.0 lbs (5.0 kg) each

• RMS Output (Real power): 70 Watts per channel (140W total) into 6 ohms, 1kHz, 10% THD.
• Music Power (PMPO - Peak Music Power Output): Advertised as 1,400 Watts. (This is a peak-to-peak measurement; the real continuous power is 140W RMS).
• Amplifier Type: Discrete power transistors (Class AB) – not a cheap IC chip amp.
• Frequency Response: 20Hz – 20kHz (±0.5 dB)
• Total Harmonic Distortion (THD): < 0.09% at rated output.

Why this matters:

The 120W RMS per channel is real power. This unit can drive inefficient bookshelf speakers easily. The Groove Boost Circuit (a physical switch on the front) dynamically adjusts the bass equalization curve without clipping the power supply, a rare feat in this price bracket. sony lbtv702 specs exclusive
