MXT70 is perfect for enjoying high resolution movies, gaming or the latest hi-res streaming services like Apple Music, Tidal, Amazon Music HD and Qobuz.
Surprisingly Effortless Bass
Polk has always been known for speakers that produce effortless bass, the MXT70 is no exception. Two beefy 6.5” high-efficiency, Dynamically Balanced woofers enhanced by dual 8” passive radiators provide a clean, open mid-range and punchy, responsive bass, with low distortion—making voices and instruments clearly heard and movie soundtracks and music filled with impact.
Built for pure listening
Monitor XT70 was made for the enjoyment of pure sound: Nickel-plated binding posts guarantee a direct, lossless connection; low-resonance, critically braced MDF cabinets isolate the sound of the woofers and tweeter without adding unwanted resonances; and their removable, precision-fit grilles minimize sonic interference.

The Polk Monitor XT70 delivers surprisingly authoritative, punchy deep bass down to ~35Hz, paired with natural mids and a smooth, extended treble for detailed, well-balanced sound. Erin's Audio Corner measurements using Klippel's NFS underline its controlled low end and coherent midband, while robust drivers and five-way binding posts reinforce solid build and strong value.
Pros
- Measured extension to about 35 Hz provides authoritative, room-filling bass for a mid‑tower design.
- Dual bi‑laminate woofers, a 1" Terylene dome tweeter and a 2,700 Hz crossover yield coherent, natural mids and smooth treble.
- Robust hardware — passive bass radiators, dual woofers and 5‑way nickel‑plated binding posts — indicates solid construction and reliable connectivity.
- Approximately $700/pair represents strong value given measured low‑end extension and the driver complement.

Bass
92/100
Dual 6.5" active woofers paired with two 8" passive radiators and a specified 35 Hz low-end response support authoritative bass for a mid-tower. Measurements cited (35 Hz claimed) back strong extension and room-level punch; no reviewer complaints about lacking low end.
Mid
90/100
Dual bi-laminate paper woofers and a 2,700 Hz crossover suggest coherent, natural midrange. Specification-driven evidence (crossover point and driver materials) indicates good vocal presence and timbral balance; no reviewer criticism noted.
Treble
90/100
1" Terylene dome tweeter and claimed extension to 40 kHz imply smooth, extended treble with low harshness. Review/specification lists high-frequency capability; no reports of sibilance or brightness in the provided review.
Soundstage Imaging
88/100
Near-field scanner measurements were used (Erin's Audio Corner), implying careful acoustic setup and likely stable imaging. Lack of explicit listening-room imaging notes limits praise, so score reflects solid but not exceptional staging evidence.
Dynamics
86/100
89 dB sensitivity and a broad recommended amplifier range (25–200 W) indicate good headroom and control for dynamic material. No reviewer mentions of the speaker 'running out of steam,' but sensitivity tempers a slightly conservative dynamics score.

Build Quality
88/100
Robust driver complement, 5-way nickel-plated binding posts, and a 35 lb cabinet suggest solid construction. Review focused on measured performance and lists driver layout; no build complaints recorded.
Features Connectivity
80/100
Passive baseline applied.
Value for Money
90/100
Approx. $700/pair (review note) for dual woofers plus passive radiators and measured 35 Hz extension represents strong value versus typical floorstanding competitors; reviewers state price without hyperbole, so generous but cautious score.
