Modern and functional, the new Warm Up balaclava perfectly protects the nape, temples, and chin against the wind.
Protects the neck, temples and chin against the wind - The slight compression and the ribbed structure on the nape optimize the fit while at the same time preventing heat dispersion and providing insulation from the outside.
The mesh areas over the mouth, nose and ears facilitate the dispersion of heat in the areas most exposed to perspiration.
Ideal for colder climates and winter use.

The DALI SPEKTOR 6, like all DALI loudspeakers, has been designed in accordance with our fundamental acoustic and electro-acoustic principles, and a strong belief that clarity and an authentic, honest sound reproduction will get you even closer to the full impact of a live music experience..
WIDE DISPERSION:DALI makes it easy to integrate your loudspeakers into any room. Both the driver materials and geometry applied in the SPEKTOR 6 have been selected to achieve a wide dispersion pattern. An added benefit is hugely reduced harmonic distortion and diffractions causing frequency distortion, as these will always be stronger in an on-axis response. This is also the reason why all DALI speakers are not designed for toeing-in..
TWEETER: The SPEKTOR 6 tweeter is able to render high frequencies with high accuracy. This means very short excursions, but at high speed, - or rather – with high acceleration. In other words, it features a low moving mass and a strong motor..
WOOFER: The SPEKTOR 6 sound signature is build around two 6,5” woofers, which are developed specifically for this speaker. Even small details like the angle of the wood fibre cone and the size of the dust cap is optimized for the best possible integration, dispersion and performance in ....

Improved design & strength and ease of assembly.
Tri-disc foam structure provides maximum energy dispersion.
PowerTransferRing collar offers superior impact and absorption and re-coil.
PowerCore steel plate technology improves the overall strength.
Compact base allows for increased accessibility.
PowerCore steel plate technology improves the overall strength. Height is adjustable from 54 to 65 inches.
