ALCHEMY RX

Alchemy RX — Alumapro's Flagship Competition Subwoofer

The Alchemy RX is the pinnacle of the Alumapro lineup. Everything that makes the Alchemy series legendary, taken to the extreme — a massive motor structure with integral forced-air cooling that effectively doubles power capacity, a pure copper shorting ring that cancels harmonic distortion, and an FEA-optimized aluminum alloy cone assembly that increases strength while reducing moving mass.

Rugged Santoprene surround for maximum excursion and linearity under the widest operating extremes. Laminated dual spider assembly for long-term performance and reliability. Built for enthusiasts who demand the absolute best from their system.

Which Alchemy RX is right for you?

All three RX 12 models share the same motor, proprietary cast frame, 15 mm Xmax, mounting size and 500 W RMS / 1,000 W rating, and they look the same from the outside. The difference is in the suspension and tuning, which decides the box each one is built for.
