The drivers fire down or backward, dialogue vanishes under the score, and the easy fix is a soundbar. The Monitor Audio Radius On Wall 4G is the other answer: a real two-way loudspeaker, just 78 mm deep, built to hang beside or below your screen and get out of the way.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eMonitor Audio launched the Radius Series 4G in June 2026, and the On Wall is its home cinema specialist. Each cabinet carries two 4.5-inch C-CAM RST III bass-mid drivers flanking a 25 mm C-CAM Gold Dome tweeter. In-room response runs from 69 Hz to 35 kHz at −6 dB, installed sensitivity is 90 dB, and maximum peak SPL is 114 dB — the highest output figures in the range.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe cabinet measures 750 x 154 x 78 mm, about 29.5 by 6.1 by 3.1 inches, and weighs 6.4 kg. Mount it horizontally under the screen as a center channel or vertically to either side; the MA roundel logo lifts off, so the face stays clean either way. It ships singly in high gloss black or satin white.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eRST III Cones, a Vented Gold Dome, and Bolts Through the Cabinet\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eC-CAM stands for Ceramic-Coated Aluminium\/Magnesium, Monitor Audio’s signature cone material. This generation adds RST III cone geometry, a ribbed surface that pushes breakup and resonance out of the range you actually hear, plus redesigned surrounds and bigger magnets. The tweeter changed more: an external magnet motor in place of the traditional internal puck magnet, a fully vented dome and former, and a UD waveguide to shape dispersion.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eDispersion matters on a TV speaker, because half your seats are off to one side. Even coverage keeps dialogue clear from the end of the sofa. The cabinet helps too. Through-bolt bracing anchors each driver to the rear panel under controlled torque, a HiVe II port is tuned to 62 Hz, and a new crossover hands off at 2.3 kHz.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWho Is This On-Wall Speaker Best For?\u003c\/h2\u003e\n\u003cul style=\"margin:0 0 0.9em 0;padding-left:1.4em;line-height:1.6;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnyone ready to retire a soundbar\u003c\/strong\u003e — Two 4.5-inch drivers and a real tweeter beat a slim bar, especially on dialogue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHome cinema builders\u003c\/strong\u003e — Sold singly, so you buy exactly as many as your layout needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRooms with no floor to spare\u003c\/strong\u003e — At 78 mm deep, it lives beside a wall-mounted screen without looking bolted on.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide or off-center seating\u003c\/strong\u003e — The vented Gold Dome tweeter and UD waveguide cover a couch, not one sweet spot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot right if you cannot drill the wall\u003c\/strong\u003e — The bracket in the box is how this speaker sits.

Run your speaker cable to the wall position first, because chasing cable afterward is the part everyone regrets. In a home theater, set your receiver crossover near 80 Hz and hand the bottom end to a subwoofer.
