High Definition Pinnacle Ring Radiator Tweeter

Over 40 years of tweeter innovation, design and prototyping has led to the development of the new 1” high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” while the critically damped rear-chamber helps defeat any unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in movies, sports, and video game soundtracks.

6.5” Turbine Cone

Polk developed the Turbine cone specifically for our flagship products to ensure the natural reproduction of the mid-range, to which human ears are particularly sensitive. The Turbine cone combines Polk’s proprietary foam core and molded Turbine geometry which dramatically increases stiffness and damping, without adding mass. You will hear every detail and experience a smooth, detailed mid-range and effortless bass.

Polk Newly Patented X-Port (ETF)

Polk’s newly patented X-Port incorporates an Eigentone Filter (ETF) offering distortion-free, effortless bass. Consisting of a set of closed-pipe absorbers that are specifically tuned to catch and eliminate traditional speaker distortions. X-Port ensures that the upper bass and mid-range are free of port and cabinet resonances for smooth, detailed audio.

Whether it’s vinyl, Spotify, or cinematic surround sound—you’ll hear it like never before.

Beautiful Inside and Out

Designed to stand out and fit in, the Amp Ultra features a sleek unibody aluminum chassis and a vibrant 3.5″ glass-covered touchscreen. Easily control playback, switch sources, view album art, and more—all at your fingertips.

Flagship Components, Flawless Fidelity

Under the hood, the Amp Ultra is powered by top-tier components:

ESS ES9039Q2M SABRE DAC
Dual TI TPA3255 Class-D amplifiers
Six TI OPA1612 op-amps

Combined with Post Filter Feedback (PFFB) technology, it delivers clean, detailed sound with consistent performance across all speaker loads—perfect for bookshelf, floor-standing, or in-wall speakers.

Post Filter Feedback Technology

At the core of the WiiM Amp Ultra’s superior sound is its advanced Post-Filter Feedback (PFFB) technology, a cutting-edge refinement system that minimizes distortion, enhances clarity, and ensures consistent sound quality across different speaker loads. Unlike traditional amplifiers that suffer from load-dependent performance variations, PFFB dynamically compensates for these inconsistencies, delivering a more accurate, balanced, and natural sound signature. The result? A wider soundstage, richer details, and an immersive listening experience that faithfully reproduces every note with precision and depth.

Advanced Thermal Management

High-power amplification generates heat, but the WiiM Amp Ultra stays cool under pressure with advanced thermal management:

• Copper Heat Pipe – Rapidly transfers heat from key components for stable performance at any volume.
  
• Large Aluminum Heatsink – Exceptional conductivity ensures fast, efficient cooling, preventing thermal throttling.
  
• Precision PID Control – Real-time temperature regulation for optimal cooling and long-term reliability.
