Martin Logan B2 speakers (Walnut) with WiiM AMP Ultra

Pairing the MartinLogan Motion Foundation B2 bookshelf speakers with the WiiM Amp Ultra makes for an outstanding, high-performance compact audio system. This combination delivers excellent power, high-resolution streaming, and room-filling sound at an accessible price.

Why They Work Well Together

• Power & Control:The B2s are 5-ohm speakers that handle up to 100 watts. The WiiM Amp Ultra outputs a robust 200W per channel at 4 ohms (or 100W into 8 ohms) using upgraded Texas Instruments Class-D chips and Post-Filter Feedback (PFFB). This guarantees excellent control, deep bass, and effortless dynamics without distortion.
• Signature Sound: The B2 utilizes a 6.5" aluminum mid-bass driver and a Gen2 Folded Motion Tweeter, which provides a massive, airy soundstage. The WiiM Amp Ultra features a premium ESS Sabre DAC and automated room correction (RoomFit), which helps tailor the output specifically to your room's acoustics for crystal clear vocals and instruments.
• Smart Features: You get Wi-Fi 6, Bluetooth 5.3, and a beautiful 3.5” glass touchscreen. The amp also includes an HDMI ARC port, making it a brilliant upgrade for your TV audio.
