Diamond 225 Bookshelf Speakers

Sold Out $849.99

The Diamond 225 is the largest bookshelf speaker in the Diamond 200 Series — a two-way standmount for medium to larger rooms where a floorstander won’t fit. Its 165 mm woven Kevlar cone bass/mid driver and 25 mm soft-dome tweeter reach a 40 Hz bass extension for genuine low-end weight.

A 10.3 L slot-loaded bass-reflex cabinet crossing over at 2.3 kHz keeps the Diamond 225 composed up to a 96 dB peak SPL across a 45 Hz – 20 kHz response. At 87 dB sensitivity and 8 Ω (4.2 Ω minimum), it handles amplifiers from 25 to 120 W with ease.

It tops the standmount range in the Diamond 200 Series; for deeper bass, the 230, 240 and 250 floorstanders await. Or explore all our bookshelf speakers.

Wharfedale Australia is the official, AVR-authorised distributor — every Diamond 225 is backed by genuine Australian warranty and local support.

You Wanted Great Sound, Low Cost & Zero Complications. We Agreed.

Over eighty years at the leading edge of loudspeaker design and manufacturing has taught us one important thing, keep it simple. Wharfedale Diamond series is about simple design principles matched with simple design features at a truly affordable price. It’s why Diamond is one of our most successful speaker series ever. With Diamond 200, yes we’ve improved the driver technology, utilised Kevlar woven woofers and included a new slot- loaded bass porting system. But it’s still just a speaker, albeit an incredibly dynamic, very affordable speaker. It’s what you wanted. So we thought, why complicate it?

Speakers Built For Your Listening Tastes & Space, Not Ours.

Improved cabinet construction and materials means you hear more of the drivers and less of the cabinet, making your favourite artists come to life.

Diamond 200 drivers boast the latest hi-fi technology to deliver wonderfully textured vocals with dynamic instrumentation. Music is more expressive, more compelling than ever before. And the new slot-loading technology permits near-wall positioning, meaning they’ll sound great wherever you place them. Music tastes, listening space, vinyl CDs and streaming; we’re all beautifully different. So we built loudspeakers that best suit your circumstances, not ours.

The Diamond Cut The Best Suits You

Diamond 225 are a 2-way bookshelf loudspeaker featuring 25mm soft dome tweeters and 165mm woven kevlar bass drivers. Combined with a larger chassis than both Diamond 210 and 220 (355mm x 196mm x 262mm),
Diamond 225 offer substantially deeper bass response and noticeably wider dynamic range, perfect for medium to large sized living rooms and bedroom spaces. However, new slot-loading bass ports permit near-wall positioning, so they’ll sound great almost anywhere you put them. Enjoy all the dynamics, all the clarity, all the texture of high-fidelity audio from our largest Diamond 200 bookshelf speaker, and experience music like never before thanks to Diamond 225
