Sound Characteristics and Merits of Wharfedale Diamond 9.1

After all these years, the Wharfedale Diamond 9.1 is still quite a looker, it may not look modern enough but with the speaker grills on, it will still blend in well with most home decorations and amplifiers. When you take off the grill, you will immediately notice two bass ports, located right below the bass drive unit. The first thing we thought about will be the ease of speaker placement, then start to wonder how powerful will Diamond 9.1 bass output be. We are genuinely surprised by their frequency response of 50Hz – 24kHz, which is very impressive for a bookshelf speaker of this size.

There is also a 25mm (1 inch) textile tweeter and a 130mm Kevlar bass/midrange cone. The recommended amplifier requirement starts from 20-100 Watts but with a nominal impedance of 6 Ohms and speaker sensitivity of 86 dB, which immediately shows how inefficient the Wharfedale Diamond 9.1 is. To play these bookshelf speakers at high volume will require high power amplifiers unless you are planning to add in an active subwoofer which allows the amplifier to focus all its power on the rest of the higher frequency reproduction. All these will further determine what type of amplifiers we should get.

At first, we thought we will be bombarded by exaggerated bass reproduction but were very delighted to find out that the Wharfedale Diamond 9.1 actually delivers a clean and balanced music presentation. There are plenty of details in its sound reproduction and the clarity is certainly unexpected from a speaker at this price point. The Wharfedale Diamond 9.1 are certainly easy on the ears, never once sounded harsh or hard, rather a warm and smooth music delivery. A little bit brighter sounding will be amazing though but still can be easily solved by adjusting the treble level setting.

The quality of the bass really astonishes us, it is deep and controlled, placing them nearer to the wall does help to improve the mid-bass response and slightly increase the weight. Still, the bass reproduction exceeded our expectations in terms of sheer quality, the bass ports are finely tuned and are not meant to deliver boomy bass. The neutral warm sonic characteristics and unfussy nature does help in finding a matching amplifier a lot easier. Mixing in a subwoofer should improve the overall transparency and increases the size of the soundstage. You might want to consider getting a powered sub.

The Wharfedale Diamond 9.1 would most definitely do well in a home theater setup as surround speakers, their smooth sounding quality will be great for reproducing ambient sounds. The size of these standmounters will be ideal for desktop use too but the aesthetic feel may lose out to more modern speakers.
