HST Series - The Optimal Blend Of Resplendence And Force
You’re perched upon the horns of a dilemma. As the consummate, distinguished lady or gentleman you desire a meticulous subsonic performance from your subwoofer. However you also possess a mischievous side; an adventurous streak that sends a rush of blood to the head from time to time causing you to crank the volume to such a point you struggle to breath. It takes a special type of subwoofer to blend such astounding accuracy with copious levels of volume. This is the territory in which Stereo Integrity's legendary HST range are most comfortable residing. These drivers not only provide delightful quality and control; they can hit like an howitzer when required.

Design Ideologies
Discover the ultimate destination in your quest for the perfect subwoofer; the HST series from Stereo Integrity! These powerhouses are the epitome of balance; delivering high-fidelity sound, impressive output and in an infinite baffle mount. All while excelling in low frequency effects and infrasonic ultra-low frequency performance. With a bandwidth potential ranging from 5 Hz to 95 Hz, the HST subwoofers effortlessly flex their muscles to transport you to the realm of profound subsonics. Every part of the HST program is designed using FEA simulations, CAD software and Klippel verification for the final subwoofer drivers.

Abilities Extrodinare
The award winning HST series are designed for massive amounts of bass out of very small enclosures. Despite their size, these drivers exhibit the sonic precision of a far smaller woofers. They offer an immense linear displacement potential, allowing you to easily delve into full bandwidth sound; even down into the single digits. To achieve this these mammoth drivers are equipped with very long stroke, high motor force, motors with triple shorting rings and a bifilar copper voice coil that is capable of 40 mm of one-way linear travel. That’s right; 80 mm of total linear travel and 102 mm of total peak excursion.

Compliant Suspension
Flat and linear suspension compliance is achieved by utilizing a wide soft foam surround and a three layer natural color 10″ / 254 mm diameter Nomex spider. The spiders have sewn-on flat voice coil leads which completely eliminate lead tap.

Holding It All Together
A high-clearance, magnetically inert cast aluminum frame is used to support the moving parts and the large 250 mm triple stacked motor structure. Large 4 Awg push terminals allow you all the wiring access needed for hookups. Last but not least is our Carbon Fiber sandwich cone and dust cap for extremely high cone stiffness, thus eliminating any cone distortion.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Some of these include:
– The HST series are designed for high-output power, creating bass you can feel resulting in a more immersive audio experience.
– A custom designed, high-BL motor.
– Dual large diameter voice coils. These coils offer unparalleled audio clarity and resonance, resulting in superior sound quality.
– High continuous power handling ability. This uncompromising power output enables you to accentuate even the lowest-frequency sound waves, ensuring you hear every subtle nuance in your music.
– Triple internal shorting rings to control and linearise inductance.
– Specially crafted for infinite baffle mounting, yet it doesn’t compromise on sound output.
– Klippel optimized motor. Because of its finite element analysis (FEA) optimized motor and advanced Faraday ring technology, this subwoofer offers superior performance.
– Enormous proprietary multi-stacked Y35 ferrite motor for high motor force and minimal enclosure requirements.
– Superior cooling system for optimum thermal efficiency.
– Expertly designed motor topology.
– Advanced carbon fibre sandwich composite cone is very light. Less moving mass reduces distortion for smoother audio response.
– Stylish framework thanks to its eight spoke magnetically inert aluminium basket.
– Long throw Xmax for ultra-low frequency extensions.

A Note About The Pricing
We’re sometimes asked why Australian prices are higher than those listed overseas. Allow us to explain how we stores arrive at the price for these components.
– You first take the US price and run it through an exchange website to covert it to Australian dollars.
– You then have to add ten percent for GST tax. The Australian government stipulates that this tax is compulsory, therefore it must be added.
– You then add the cost of air-freighting to Australia. Now products can be shipped via surface freight but the wait can sometimes drag out many months. For a weighty product like this the cost is quite a few hundred.

Put succinctly; between our dollar not being so strong against the US dollar, European euro or British pound, in addition to us being far away geographically; this is conducive to products costing more here in Australia.
