Their solidity and authority throughout the frequency range relies on placement near or against a rear wall: pull them out too far in the open and that sure-footedness is diluted slightly; bass notes are looser and vocals lose a bit of substance.

In terms of the most fundamental types of music, videos, and movies, this is where the speakers continue to surprise us in relation to their true cost. Even better, you can connect it to an amplifier to slightly boost the treble. The Wharfedale Diamond 9.0 sound incredibly clear and clean when you’ve done that.

With a front port, these bass reflex speakers are punchier than you might expect and in no way could they ever be described as tinny. Over all, they may be small but the sound is grown-up, with excellent staging, realism and surprisingly powerful. While such character might have initial showroom appeal, it can become wearing after a time and is not what hi-fi ought really to be about.

To compare the speakers you would need to accurately know the specifications and the original selling price.

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. The Wharfedale Diamond range has enjoyed a formidable reputation within the field of two-channel stereo reproduction. Fig.3 Wharfedale Diamond 9.1, acoustic crossover on tweeter axis at 50", corrected for microphone response, with nearfield responses of woofer and port, plotted below 300Hz and 1kHz, respectively. You aren't getting any responses because you are asking an impossible question. When it gets down to two speakers, then only you wallet and your ears can tell you which is right. Some very slight wrinkles in the impedance traces between 150Hz and 900Hz imply the existence of some cabinet resonances. Investigating the panels' vibrational behavior with a plastic-tape accelerometer revealed a strong resonant mode present on all surfaces, but strongest on the sidewall (fig.2). Other modes existed at 465Hz and 900Hz but were not as strong. This mode is a little high in frequency to contribute to the "warmth" BJR noted in his auditioning; though it might add some midrange congestion with some kinds of music, Bob Reina didn't hear anything untoward in this respect.

The Infinity Primus 150 was a bit cleaner in the midbass and upper bass, but with no more bass extension than the Wharfedale. The midrange was natural, the high frequencies more extended but less detailed and delicate than the Wharfedale's, which also had slightly better high-level dynamics. For those considering buying speakers from Wharfedale, but aren’t exactly sure of the Wharfedale Diamond 9.0, there is a list of similar models. The cabinet isn't just compact, it's also very solid. This combination gives the Diamonds an extremely accurate sound quality as the cabinet doesn't flex or vibrate. Equally impressive are the drive units. A soft dome tweeter gives the clarity and smoothness of sound you'd expect from a more expensive speaker, while the woofer cone uses a carbon fibre type weave to offer extremely taut and responsive bass. The Wharfedale 9.1 is capable of playing songs when it comes to any music genre. Of course, you can also connect the speakers to your TV and use the speaker system when you’re watching films or videos.In John Rutter's Requiem (CD, Reference RR-57CD), the cello and flute were as natural as I've heard from any budget speaker, and the male choir was layered across the wide, deep soundstage as realistically as I've heard from any speaker at any price.
