Score: 81/100Rankings
The Polk Monitor XT15 is a compact two-way bookshelf speaker pair offering Hi-Res audio up to 40 kHz and integrated Dolby Atmos/DTS-X support. Its limited low-frequency response and narrow vertical dispersion can restrict bass performance and placement flexibility. Ideal for small to medium rooms where clarity and detail are prioritized.
The Logitech Z906 is a THX-certified 5.1 surround system delivering 500 W RMS for immersive home-theater audio. Its fully wired design and lack of wireless connectivity limit flexibility for modern setups. Ideal for gamers and movie enthusiasts who prioritize raw power and surround decoding over wireless convenience.
