Overview

The Monoprice Monolith T4 Tower Speaker from the Audition Series is designed to bring high-performance audio into your home without demanding a high-end price. At its core, the T4 pairs a 20mm silk dome tweeter set within a custom-engineered waveguide with dual 4-inch woofers, creating a speaker that covers a wide frequency range with clarity and detail. The waveguide helps control the tweeter's dispersion pattern, resulting in a more focused and consistent listening experience across a broader sweet spot in your room.

Build quality is a highlight at this price tier. The cabinet is constructed from MDF with internal bracing, a design choice that reduces panel resonance and keeps the sound clean even at higher volumes. The black PVC finish is understated and professional, blending easily into most room setups. As a passive floor-standing speaker, the T4 requires an external amplifier or AV receiver, giving you the flexibility to choose your own electronics. Whether deployed as a stereo pair for music listening or as part of a larger surround sound system for movies and gaming, the Monolith T4 offers a compelling combination of performance and affordability that makes quality audio accessible.

Key Features

Tweeter Waveguide: Silk Dome Tweeter. Distinctive Look. A 20mm soft dome tweeter sits inside a large, customized waveguide for better dispersion, a wider sweet spot for stereo listening, and spectacular imaging. The distinctive waveguide enhances tweeter performance, and gives the speaker a sleek appearance in any room.

Transparent Midrange and Punchy Bass: Quality midrange and bass begins with quality drivers. Each Encore series woofer has been designed to be both lightweight and rigid for midrange transparency and quick, punchy bass.

Quality Cabinet Construction: Sturdy, well-constructed MDF cabinets wrapped in a premium vinyl finish are built with thick internal bracing that suppresses unwanted cabinet resonances that may color the sound.

Connectivity: Each Audition speaker comes equipped with dual 5-way binding posts for a quick and easy installation.
