KEF vs HiVi-Swans Bookshelf Specs
Driver Configuration
Edge: HiVi-Swans D3.1 MKII 6.5" Passive Speakers
The KEF Q1 Meta uses a 5.25-inch bass/midrange driver combined with a dedicated tweeter to handle high frequencies. This 2-way design aims for clear vocals and detailed sound. The HiVi-Swans D3.1 MKII features a larger 6.5-inch woofer paired with a 28mm dome tweeter. The larger woofer in the HiVi-Swans suggests a potential for deeper bass extension and more powerful low-frequency output compared to the smaller KEF unit. Both are two-way systems, but the driver size difference is significant for your listening preference.
Physical Dimensions
Edge: KEF Q1 Meta Bookshelf Speakers
Size matters for placement. The KEF Q1 Meta is compact, measuring 11.9 inches in height, 7.1 inches in width, and 10.9 inches in length. It weighs 13.4 pounds per speaker. The HiVi-Swans D3.1 MKII is substantially larger, standing 14.9 inches tall, 8.58 inches wide, and 14.2 inches deep. Each HiVi-Swans speaker weighs 48.5 pounds. The KEF fits easily on smaller shelves or stands in tighter spaces, while the HiVi-Swans requires a sturdy, spacious surface to accommodate its bulk and mass.
Cabinet Design
Edge: HiVi-Swans D3.1 MKII 6.5" Passive Speakers
Build quality affects sound purity and aesthetics. The HiVi-Swans D3.1 MKII uses high-density wood with internal bracing to minimize resonance. It features a classic acoustic tilt design with a detachable front baffle, allowing you to angle the sound axis toward your listening position. The cabinet also has a genuine wood veneer finish. The KEF Q1 Meta focuses on compact engineering with Metamaterial Absorption Technology to reduce distortion. Its design is contemporary and minimalist, prioritizing space efficiency over adjustable acoustic tilting.
Bass Performance
Edge: HiVi-Swans D3.1 MKII 6.5" Passive Speakers
Low-frequency response is critical for full-range sound. The HiVi-Swans D3.1 MKII utilizes a back-placed inverter tube design. This integrated port aims to lower wind noise and deliver shocking bass at resonance frequencies. The larger 6.5-inch driver supports this powerful bass claim. The KEF Q1 Meta relies on its 5.25-inch driver for punchy, controlled bass. While efficient for its size, it lacks the dedicated porting and larger cone area of the HiVi-Swans, potentially resulting in less deep bass extension in the same room.
Weight and Stability
Edge: HiVi-Swans D3.1 MKII 6.5" Passive Speakers
Speaker weight impacts stability and vibration control. The HiVi-Swans D3.1 MKII weighs 48.5 pounds per unit, providing significant mass that helps dampen cabinet vibrations and keeps the speaker firmly in place during high-volume playback. The KEF Q1 Meta weighs only 13.4 pounds per speaker. While lighter, this makes the KEF easier to move and position on various stands. However, the heavier HiVi-Swans may offer better isolation from floor vibrations if placed on standard furniture.
