ASP Series · Performance Amplifiers

Power That
Speaks For Itself.

From 1,800W to 5,000W RMS — independently verified at 1-Ohm. The ASP Series is built for builders who demand real output. 4-layer PCB with 2oz copper traces. Class D mono efficiency. Zero fine print on the spec sheet.

Why ASP Series

The Performance
Standard.

The ASP Series exists for one reason: builders who have been burned by inflated numbers and need a manufacturer they can trust. Every ASP amplifier ships with independently lab-verified output — measured above its rated specification in every case. Not once. Not on select units. Every unit.

Four mono models from 1,800W to 5,000W and one high-output 4-channel — all on a 4-layer SMD PCB with 2oz copper traces. The same verified standard applied at every wattage level.

01
Measured Above Rated — Every Unit
Every ASP amplifier has been independently tested and measured above its rated output. 1,897W on the 1800. 2,597W on the 2500. 3,714W on the 3500. 5,016W on the 5000. Printed on the box. No asterisks.
02
4-Layer SMD · 2oz Copper PCB
Twice the copper mass of a standard PCB. Dedicated internal power and ground planes. Lower trace resistance, more thermal headroom, and structural rigidity that survives sustained high-power operation.
03
1-Ohm Stable · All Mono Models
All four mono ASP models are independently verified at 1-ohm. Not rated at 1-ohm with fine print about thermal limits or duty cycle. Tested, stable, and printed on the box without qualification.
04
No Peak Numbers. Ever.
The ASP Series does not publish peak figures. Every watt on every spec sheet is RMS, measured under real-world operating conditions. The number on the box is the number the amplifier delivers.
