Wharfedale 9.0 Bookshelf Speakers - Premium Audio Quality

Product Information

As might be expected from its small size, the Diamond 9.1 is of below-average voltage sensitivity, at an estimated 85.5dB(B)/2.83V/m. However, its impedance plot (fig.1), other than a dip to 3.9 ohms in the lower midrange and a combination of 5.7 ohms impedance and –36° capacitive phase angle at 120Hz, indicates that the speaker should be fairly easy to drive. Prices valid in stores (all including VAT) until close of business on 29th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) For those looking for serious details, I am enclosing the detailed specifications of Wharfedale Diamond 9.0.

The impedance plot indicates that the small woofer's reflex loading is tuned to 50Hz. However, as can be seen in fig.3, the expected notch in its response actually occurs a little lower in frequency, at 45Hz, with the twin ports covering a wide bandpass from 30Hz to 120Hz. (The outputs of the woofer and ports in this graph are scaled in the ratio of the square roots of their radiating areas.) The ports' higher-frequency rollout is free from the spikes that would indicate the presence of resonances, while the woofer crosses over to the tweeter at approximately 2kHz, with some overlap apparent. Both drivers mainly have relatively flat outputs within their respective passbands, with peaks balanced by dips.

One trade-off of not having a dedicated self-powered sub is that the system needs a little more power from the amplifier, say around 100 W/channel (ignore the maker's fi gures here), but this is a ballpark fi gure for even relatively inexpensive multichannel amplifi ers these days. Otherwise you'll fi nd the system easy to confi gure. I noted that the speakers have somewhat broader dispersion that usual, and this means a much larger sweet spot where several listeners will hear good sound, not just in a single listening sweet spot. The Wharfedale diamond 9.1 speakers can be bi-wired, which means you can connect more audio speakers to your hi-fi system. This will assure a separation of the single paths to the high and low frequencies resulting in cleaner and more precise sound.

The Wharfedale Diamond 9.0 speakers are totally fine for the purpose of playing songs, gaming, watching movies and videos. The sound is smoothly clean, but the speakers aren’t the best if you are looking for tons of bass.

So are the Wharfedale Diamond 9.0 speakers still worth looking into, or it is a waste of money in 2019? Let’s Find out. Performance & Sound Source – https://www.cnet.com/products/wharfedale-diamond-9-0-speaker/specs/ Similar Models of WharfedaleIf you’re looking for low budget speakers, which are performing good in terms of basic music listening, the Wharfedale Diamond 9.0 speakers are a great choice for you. This is certainly true of the enclosure, which has curved sides to add stiffness to the structure and disperse horizontal standing waves and reflections. Twin ports, claimed to reduce distortion by 40 per cent, are fitted into the front panel.

In terms of build quality, the speaker’s binding posts have a cast-metal housing. The front ports are also made of metal, which is considered as a big pro. Woofer of the Wharfedale diamond 9.1 has a metal frame as well, feeling very strong even though it’s very thin. If you hate to see a plastic material stuff on bookshelf speakers such as I do, then the Wharfedale diamond 9.1s won’t be a disappointment to you. The Wharfedale diamond 9.1 speakers weigh 12lbs.

Whether the Diamond 9.0 will serve you depends on your requirements. If you are planning to throw a Rave, then you are going to be disappointed. But if this is for casual, though somewhat loud, listening, then you will probably be satisfied.
