Remarks:
The Tannoy Little Red Monitor (LRM) is a classic 12-inch dual concentric studio monitor known for its 92dB sensitivity, 55Hz-20kHz frequency response (+/- 4dB), 6Ω impedance, and 10-200W recommended power, featuring a 300mm paper cone woofer with an aluminum dome tweeter for precise imaging, often praised for detailed mids and solid bass despite its compact size for a Tannoy.
Key Specifications:
Driver Type: 300mm (12") Dual Concentric (Type 3149R)
Frequency Response: 55Hz – 20kHz (+/- 4dB)
Sensitivity: 92dB (1W @ 1m)
Impedance: 6Ω (4Ω minimum)
Recommended Amplifier Power: 10 – 200W
Enclosure: Bass Reflex
Dimensions (H x W x D): 548 x 400 x 275mm (23" x 16" x 11")
Weight: 21 kg (46 lbs) each
Key Features:
Coaxial Design:
The woofer and tweeter are mounted coaxially for a single point source of sound, improving imaging.
Time Alignment:
Includes a time-delay circuit in the crossover to align the phase of the woofer and tweeter, a necessity due to the shorter horn throat from the ferrite magnet design.
Construction:
Features rigid paper cones for the woofer and aluminum domes for the tweeter, housed in robust enclosures.
Legacy:
Highly regarded professional monitors from the 1980s, known for their detailed sound and classic Tannoy quality
