Wharfedale Diamond 12.1i Bookshelf Speakers
Since its launch in 2020, the Wharfedale Diamond 12 Series has received widespread praise as a benchmark for performance and value in affordable hi-fi speakers. After five years of consistent success and awards, Wharfedale now introduces the updated Diamond 12i Series — featuring luxurious modern finishes and subtle acoustic refinements that build on the original’s exceptional foundation.
The Diamond 12.1i is a versatile 2-way bookshelf speaker that delivers impressive sound quality with greater bass extension than its smaller 12.0i sibling. Its 130mm woven Kevlar woofer, 25mm soft dome tweeter, and slot-loaded distributed port deliver powerful, controlled low frequencies, natural midrange clarity, and detailed high-frequency reproduction — perfect for stereo music listening, home theatre, or multi-channel setups.

Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
