Many Monoprice in‑wall and in‑ceiling models use carbon‑fiber woofers and midranges; other models list aramid‑fiber woofers and titanium silk‑dome tweeters.
They use 106 mm planar drivers in a closed‑back design for isolation, and list removable earpads, large comfortable cushions, and a padded headband. Supplied earpad options include memory‑foam lambskin and velour, and listings also show weight and ear‑cushion details.
Grilles are described as metal, magnetic, and paintable to match walls or ceilings so they “virtually disappear.” Listings also mention slim bezels and low‑profile grilles for a discreet appearance.
Listings show 6.5‑inch and 8‑inch woofers for in‑ceiling/in‑wall speakers, 3.5‑inch midranges and 1‑inch silk‑dome tweeters for some models, and a 10‑inch powered subwoofer in the slim subwoofer listing.
Installed speakers include a built‑in high‑frequency attenuator for controlling brightness. The subwoofer provides volume, low‑pass filter and phase controls, and offers both line‑level RCA and speaker‑level inputs.
