Speaker Power | Avenue University — Trained On, Distributed By Avenue Sound India

Why we distribute it

Power that's rated for what it actually has to do

Most amplifier spec sheets quote a peak number and hope nobody asks about sustained output into a real subwoofer load. Speaker Power's line is built around the opposite idea.

Speaker Power builds a curated range of off-the-shelf plate and rack amplifiers, alongside custom OEM builds — from PCB and firmware through to fit and finish — for manufacturers and integrators who need a specific solution rather than a generic one.

Every unit ships from Irvine backed by a three-year parts-and-labor warranty, with the same team still supporting amplifiers built more than two decades ago. For Avenue Sound, that durability matters as much as the wattage on the box — a subwoofer amp is the one component in a home theater a client should never have to think about again.

Full-bridge output topology eliminates current pumping at high power, and the dual-monoblock architecture on the rack series keeps each channel's performance independent and consistent — which is exactly what our calibration training teaches integrators to measure for.

Curated + Custom

Off-the-shelf plate and rack amplifiers, or a fully custom OEM build tailored to a manufacturer's spec.

Full-bridge, dual-monoblock

Consistent high-power output per channel, without the current pumping that limits cheaper Class-D designs.

Built to be serviced, not replaced

Three-year warranty and long-tail support — the same philosophy Avenue Sound applies to every install we stand behind.

The lineup

Plate, rack, and standalone — one job each

Three formats built around the same Class-D topology and DSP control set, sized for where the amplifier needs to live: inside an enclosure, in a rack, or on its own.

Fits where rack space doesn't exist

Same 3-mode trigger, full DSP control set (gain, LF adjust, crossover, delay) and full-bridge output as the rest of the range — in a compact chassis that sits alongside the sub instead of inside it.

HTRx Series · Multi-Channel Class D Amplifiers

ICEpower-based Class D amplification across 4- and 8-channel fanless platforms — engineered for full, sustained output at bass frequencies rather than short-burst headline numbers.
