Where Elegance Meets Uncompromising Audio Performance
The Diamond is a flagship series in the TAGA Harmony speaker category.
It is the culmination of years of research and development, aiming to exceed the expectations of audiophiles and music enthusiasts.
This series combines state-of-the-art technology, premium materials, and a timeless design to create an audio experience that is nothing short of extraordinary.

The Diamond B-60 v.3 is the flagship bookshelf speaker incorporating a 2-way design and a characteristic oval shape of the enclosure.
The sound style is a further development of the original Diamond B-60 speakers so highly acknowledged and prized on the market.
TAGA Harmony has implemented upgrades in all crucial components, which are responsible for the sound resulting in the stunning sound performance far beyond the price range of the model.
The speaker's enclosure is expertly crafted with premium materials and finished with a luxurious veneer, adding a touch of sophistication to any listening space.

The Diamond B-60 v.3 Loudspeaker is a testament to our commitment to delivering an audio experience that transcends expectations.
From its exquisite design to its unparalleled performance, this loudspeaker is a celebration of both art and engineering.


The 2nd generation STLIE-I enclosure (Super Taga Low Interference Enclosures) which use more rigid structure and thicker MDF walls (up to 30 mm in certain parts) to limit unwanted resonances. The bent shape of the side walls as well as the curved top plays a significant role in lowering unwanted vibrations, diffraction, turbulences and standing waves effect.
The walls are firmly anchored to a rigid rear backbone beam and an internal bracing board which highly strengthen the whole construction.
The enclosure is tilted backwards to time-align all the drivers and to further limit unwanted resonances and turbulences.

TAGA Harmony new logo badge placed on cabinet front panel - shows our strive and passion for the perfect harmony of the sound performance.

Magnetically mountable grill - helps to keep more sleek appearance of the speaker as well as lower distortions when the grill is taken off.

High-end enclosure damping material to better break up the standing waves, lower resonances and limit distortions what improves the smoothness and characteristics of sound in all ranges.

High quality veneers - very durable, elegant, wood veneer finishes are coat-painted in clear gloss or matt.

Bassreflex -low-turbulence and high-velocity ports for increased dispersion of low frequencies.

The 2nd generation 36 mm (1.42”) O-TPTTD-I (Oversized Taga Pure Titanium Tweeter Dome) utilizes a light titanium dome and provides high power handling and very accurate, clear, smooth and detailed performance. Ferrofluid cooled and heavy duty 28mm CCAW and silver wiring voice coil as well as 2 magnets (Φ80 & Φ70) help the tweeter to bear high power.
The tweeter has exceptional precision and works with ultra-extended high-frequency response up to 33 kHz (+/- 3dB).
The E-TPAF (Enlarged Taga Pure Aluminum Faceplate) and metal mesh assists with equal and flat dispersion of sound in and off the axis of the driver.
Minimizing the number of components means better structural rigidity, lower distortions and resonances.

The 2nd generation 165 mm (6.5”) TNPPCD-I (Taga  Non-pressed Paper Cone Driver) bass-midrange driver – is equipped with two oversized magnets and  aluminum chassis. It is extremely rigid and utilizes vibration-free solutions. The heavy duty 2-layer copper clad aluminum (CCA) voice coil allows high power handling. It offers deep, precise and detailed performance. Thanks to a larger surface area to push air – the sound can be played at much higher levels.

Precise crossover – The crossover sections use minimal number of high quality and carefully selected components in the high-pass and low-pass crossover sections to ensure the best neutrality, to handle massive amounts of power and to provide the greatest precision.  

Internal wiring – 14AWG, made of multi-stranded Oxygen Free Copper for connecting all drivers with crossovers and to ensure that the incoming signal will not lose the most important details on the path from the amplifier to the drivers.

Binding posts - high quality posts accept raw speaker cables up to 10AWG and most popular types of connectors. Bi-Wire and Bi-Amp Capability: offering flexibility in system configuration, the Diamond B-60 v.3 supports both bi-wire and bi-amp connections for audiophiles seeking to fine-tune their setup.
