Altronics - Opus One Platinum Plus Series - Flush Mount In-Ceiling Speakers


These Opus One Platinum Plus series speakers are designed for the discerning hi-fi and home theatre listener. The customised drivers exhibit extended bass response and punchy, crisp midrange. The titanium dome tweeter is suspended allowing a greater excursion from the woven carbon fibre woofer cone. The large vented magnet, oversized voicecoil and rubber rolled surround enable a very high power handling capability.

A custom designed crossover, constructed from world class, premium components provides excellent sonic performance and clarity. Sound performance may be tailored using the built in bass and treble control switches ie. to suit the acoustics of the room or listeners preference. These are located behind the front grill and are accessed without removing the speaker from the ceiling. Features an attractive "Low Profile" magnetic grill and the Opus One standard ‘flip-lock’ mounting system. Sold in pairs.
