Technology - HH Technology



HH speakers are designed by our own Engineers in the UK, drawing on decades of design & manufacturing experience.


PA woofers

Many aspects must be considered in PA woofer design: Is it for a sub or a front-of-house cab? If front-of-house, what compression driver will it be used with? What size and type of cabinet must it suit? How many drivers will be in the cab?


Vector Range Speakers

The Vector range of PA cabinets all use 1” exit compression drivers for efficient and clear high frequency reproduction (except VRE-215, which uses the larger 1.4” exit / 50mm titanium done compression driver), and in house designed woofers using Kevlar reinforced cones, and high temperature, close wound voice coils with polyimide formers. Kevlar offers very high stiffness with low weight, reducing cone distortions, improving clarity and extending the frequency range to match the 1” exit compression drivers.


Tensor Range Speakers

The Tensor range of cabinets feature high efficiency 1” exit compression drivers with 44mm voice coils (except TRE-108, which uses a 1” exit / 25mm coil compression driver with Neodymium magnet). These high specification drivers perfectly complement the moulded horn flare giving great clarity and dispersion across the high frequency band. Tensor woofers all feature Kevlar reinforced felted cones and large diameter high power rated precision voice coils. The drivers are designed for high efficiency, giving better transient response, clarity and reliability whilst reducing thermal compression issues.


Tessen Range Speakers

All Tessen systems have cast frame, designed-for-purpose woofers with highly efficient ribbon wire coils, massive magnet structures and glass-fibre reinforced felted cones with long excursion surrounds.


Studio Lead Speakers

Electric guitar speakers are a field all of their own, actually having more in common with the ‘hi-fi’ drivers of the 1940’s than modern day PA. An electric guitar speaker contributes significantly to the sound, and in reality is one third of the instrument: electric guitar sounds good only when the guitar, amp and speaker work well together. Remove any one of those 3 components and you have nothing. At HH we have vast experience of this unique discipline, and relationships going back decades with the finest suppliers of components. Our 10” and 12” lead guitar cones are made to our exacting specification of traditional paper pulps and resin impregnations by U-Sonics Power Cone, who know more about making guitar cones than anyone. Our 6” and 8” cones are actually new tools designed and commissioned by HH, as we simply could not find cones in these sizes that were good enough.



The corners used for Studio and Queensberry combos are a good example of how we approach design.


A monitor wedge has a specific task; providing clear sonic detail to performers so they can play in time and in tune with each other.

Passive Subwoofers

High spec subwoofer drivers, featuring ribbon wire coils and Kevlar or fibreglass cone reinforcement (depending on range) provide deep but natural and musical bass extension.
