TIBO Harmony 2 – Pair of Passive / 100W / HiFi Bookshelf Speakers
Whereas most affordable speaker systems are based on drive units that are built down to a price, TIBO started with the premise that drivers should be aimed at performance. That is why the Harmony Series sports advanced driver systems incorporating elements that normally only find their way into high-end loudspeakers. For example, the bass and midrange drivers use a basket with a network of ribs that maintain the rigidity of the basket while leaving a large open area behind the cone. The rigidity improves transient impact while the big open area reduces early reflections to cone and allows the generous, specially chosen internal cabinet absorbent to do its work.
The Harmony speakers also feature massive magnet designs to both raise sensitivity and ensure absolute control of cone movement over lower bass frequencies. In addition, the use of a specially shaped single-forged pole piece with copper cap controls the magnetic flux and ensures low distortion through the critical midrange area. Then there is the progressive suspension which features a lightweight rubber surround for an extended midrange response, in conjunction with a super-long-throw voice coil motor system, to achieve unparalleled linearity and accuracy in this sector of the market. High-frequency performance has been similarly enhanced with a newly evolved tweeter design. Again, an over-sized ceramic magnet system is used, with a copper cap for flux control. And, here, the pole piece is vented through to a specially shaped rear chamber. This provides a low resonant frequency, ensuring excellent linearity throughout the operating system and allowing the silk dome to contribute to a lucid midrange performance in addition to precise high-frequency detailing. While the drive units are the heart of a loudspeaker system, they would be nothing without the integration of a precisely derived crossover. TIBO engineers use a highly evolved virtual crossover software system to help create a series of circuit options for combining the bass/midrange and treble units seamlessly. These circuit options are then evaluated using stringent listening tests over a period of months, involving a wide range of music.
Special attention is paid to the lifelike qualities of vocals and natural instruments, as these are always the focus of listeners’ subjective appraisal of a loudspeaker’s performance. While the cabinet, to the owner, is often just a piece of furniture, TIBO has long realised that it is the final piece of the design process that marks a speaker out of the ordinary. For the Harmony Series, TIBO engineers have refined the multi-layer sandwich of woods of differing density to subdue the identifiable characteristics of the cabinet ‘sound’ and so let the drive units speak for themselves. Critical bracing of the cabinet panels, together with the curving of the cabinet walls to provide a non-boxy shape, have reduced resonances more than 25dB below the driver outputs. In addition, the cabinet walls are lined with a specially developed internal fibre which has been chosen because of its outstanding absorbent qualities across a wide bandwidth. The result is that the listener hears the drive unit output unsullied by unwanted colorations caused by panel vibration or internal resonances, revealing more of the detail of the musical performance. The rear distributed port reduces the turbulence and audible ‘chuffing’ suffered by conventional ported systems, which is caused by the sudden outrush of high-pressure air into the low pressure in the room. A further benefit is to increase the efficiency of energy transfer from the bass reflex tuning to the room. This has allowed us to increase the volume of air in the slot-loaded system and further improve the performance of the low-frequency output.
The TIBO Harmony 2 is an affordable genuine Hi-Fi speaker with a stylish compact design making it a popular choice for discerning listeners. The 1” soft silk dome tweeter and 1 x 4” long throw woofer unit are more typical of speakers costing several times more. The removable neodymium grills complete the stunning performance. The Harmony range of speakers can be used as monitors for a compact studio or as a DJ unit. They can also be simply plugged into any Hi-Fi and enjoyed in the home. The Harmony 2 is a 100W speaker with 55Hz-20KHz frequency response 4-8ohms impedance and 86 dB sensitivity.
