Get deep, powerful bass from your system without compromising on style. The Monitor Audio Radius 390 brings beauty to subwoofer design.

Award-winning sound
As part of the award-winning R90 HT1 home cinema speaker package, the Radius 390 subwoofer is right at home with cinema sound. Match up with the Radius 90 and 200 speakers and you've got yourself one of the finest home cinema speaker packs in its class. Alternatively, pair with stereo speakers and enjoy a new dimension in sound from your favourite music.

Introduce thunder to soundtracks with twin bass cones
The ten inch, long throw active C-CAM bass gives the Radius 390 a high tech appeal. The seamless, aluminium construction is light and rigid, giving a rapid response to changes in sound. Helping to reinforce the bass still further, a second ABR (Auxcillary Bass Radiator) at the opposite side of the sub uses energy within the cabinet to strengthen the bass. The result is bass that drops so low it's like being at the cinema.

Powerful 220 watt Class-D amp for total control
Keeping the thunderous bass under tight control is a high current Class-D amplifier. With around 220 watts of clean power, it has little trouble in keeping the bass cone under tight control. Bass starts and stops exactly when it should, with none of the wallow and boom that afflicts lesser subs.

Three pre-set EQ modes
With Music, Movie and Impact modes you can easily change the characteristics of the subwoofer to match your mood. For the most subtle sound, choose Music. A more dynamic sound is had with the Movie mode, making it ideal for the most intense action movies. If you're in party mode or really don't like the neighbours, then switch to Impact for the most powerful sound possible.

Luxurious finish
With smooth, seamless edges and neat detailing, the Radius 390 is a premium quality subwoofer. Available in real walnut veneer, high gloss black or satin white, it's finished to a very high standard and complements the smartest decors.

Give your sound a stylish boost, with the Monitor Audio Radius 390.

Rated 5 out of 5 by from There’s a Presence in the room I bought the 390 as an upgrade to my 360 which after years of loyal service. Finally gave up the ghost. I was looking for a straight swap and was going to buy the 380 but was persuaded to go for that but extra with the 390. Fantastic advice. My new sub is a big jump in quality from the 360. I wish I had the right words to describe it - it just feels so much more ‘there’. A real presence in the room. I’m really enjoying the fuller sound I’m getting from music played via Tidal. And films just went up a notch.
