Stereo Integrity HS-24 – Dual 1 ohm & 2 ohms 24″ Carbon Fiber Subwoofer

Stereo Integrity HS 24″ Subwoofer

Discover the ultimate destination in your quest for the perfect subwoofer – the HS-24. This powerhouse is the epitome of balance, delivering high-fidelity sound, impressive output, and a compact enclosure size, all while excelling in Low-Frequency Effects and Ultra-Low Frequency performance.

With a bandwidth potential ranging from 5 Hz to 1000 Hz, this subwoofer effortlessly flexes its muscles to transport you to the realm of profound bass. Every part of the HS-24 was designed using FEA simulations, CAD software, and Klippel verficiation of the final subwoofer driver.

Despite its size, the HS-24 exhibits the sonic precision of a 10″ or 12″ subwoofer. It offers an immense linear displacement potential, allowing you to easily delve into full bandwidth sound, even into the single digits.

Three internal shorting rings provide class leading inductance reduction considering the HS-24’s massive linear excursion capabilities. Why go through the trouble to linearize and reduce inductance? For accuracy/tightness of bass. Years of meticulous refinement have led to the creation of the HS-24, the ultimate tool for authentic full-range bass reproduction.

Our HS-24 reaches a 0.707 alignment in a very compact sealed enclosure size of 8.0 ft^3. Eight cubic feet might sound a little big but when you consider that a 24″ diameter subwoofer works in an enclosure smaller than a 28″ cube the enclosure size gets very manageable very quickly. Large surface area, small sealed enclosure size, and a subwoofer capable of 40 mm one-way linear (by 70% BL) you end up with one single massively capable subwoofer solution.

Key Features:

• A custom high-BL motor
• A 3 layer 10″ diameter nomex spider for linear suspension travel
• Bifilar copper voice coil windings for reduced inductance and tighter bass
• Three internal shorting rings to control and linearize inductance
• A 10″ diameter quad-stacked Y35 ferrite motor for high motor force and minimal enclosure requirements
• 40 mm one-way Xmax (80 mm total linear excursion) with over 120 mm peak-to-peak stroke
• A compact 8 ft^3 sealed enclosure requirement
• Cast aluminum basket
• Carbon fiber and kevlar sandwich cone body
• Large 4 AWG spring-loaded speaker terminals.

For optimal performance, we recommend an 8 ft^3 sealed enclosure or a 20 ft^3 vented enclosure tuned to 15 Hz.

The HS-24 requires a 22 3/8″ (22.375″) cutout, has a 24.35″ outer diameter, a mounting depth of 12.75″, and weighs 95 lbs. Experience the ultimate in bass reproduction with the HS-24 subwoofer.
