VenmoThe KEF Reference Series Model 104/2 are highly regarded vintage floorstanding loudspeakers, known for their innovative design and exceptional sound quality
Key Technical Specifications
Configuration: 3-way, 5-driver system featuring a "coupled cavity" bass loading design.
Frequency Response: 55Hz to 20kHz (±2dB)
Sensitivity: High sensitivity at 92dB (2.83V/1m), allowing them to play loudly even with modest amplification.
Impedance: 4 ohms (nominal) with a flat impedance curve due to "Conjugate Load Matching" technology.
Dimensions & Weight: 900 x 280 x 415 mm (approx. 35.5"); weight is substantial at 32kg (70.5 lbs) each.
Key Features and Design
Coupled Cavity Bass Loading: The 104/2 uses a unique "coupled cavity" system with two internal, vertically-firing 8-inch (B200) woofers linked by a steel rod, which combine their output to a port. This design provides deep bass response (down to 35Hz ±2dB or 20Hz at -6dB with the optional KEF KUBE equalizer) from a relatively compact enclosure.
Chassis-less Midrange Units: The two 5-inch (B110) midrange drivers were designed without conventional chassis to avoid resonance issues, and are arrayed in a D'Appolito configuration around the tweeter.
Conjugate Load Matching: A complex crossover network was designed to present a near-flat 4-ohm impedance curve to the amplifier, making the speakers an easy load to drive for most quality amplifiers, despite their low impedance.
High Sensitivity: The speakers have a high sensitivity of 92dB, meaning they can be driven well by modestly powered amplifiers, though high-quality, high-current amplification reveals their full dynamic capability.
Bi-wiring: A bi-wired version of the speaker was introduced in 1990.
Performance and Reviews
Reviewers and users praise the KEF Reference 104/2 for its:
- Incredible soundstage and imaging: The speakers are noted for a vast, three-dimensional soundstage with excellent instrument placement.
- Clarity and detail: They offer very crisp and revealing sound, bringing out nuances in recordings.
- Dynamic capability: They are capable of high output levels and a wide dynamic range.
- Timeless appeal: Despite their age, many enthusiasts feel they rival modern speakers costing significantly more.
The original Manufacturer's Suggested Retail Price (MSRP) for the KEF Reference Series Model 104/2 speakers was approximately $1,600 per pair upon their introduction in 1984. The price increased over their production run, reaching up to around $3,500 per pair for the final versions by the mid-1990s.
You don't see these on the market very often.
GOTTA COME HEAR THEM! Wonderful Sound! Beautiful Cabinets!
No codes, no holds.
