Bringing you powerful bass without the bulk, the Monitor Audio Radius 380 is the discreet sub.

Introduce thunder to soundtracks with twin bass cones

The eight inch, long throw active C-CAM bass gives the Radius 380 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 to make the room shake from a modestly sized cabinet.

Powerful 200 watt Class-D amp for total control
Keeping the thunderous bass under tight control is a high current Class-D amplifier. With around 200 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!

The Radius range
The Radius 380 subwoofer is the perfect partner for the rest of the Radius speaker range. To complete a super-compact system simply match with the Radius 45 or 90 satellite speakers and the Radius 200 centre.

Luxurious finish
With smooth, seamless edges and neat detailing, the Radius 380 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 380.

Rated 5 out of 5 by from Upgrade - what a difference! I decided to upgrade my old Kef eggs, sub and Denon amp. Piers at the Maidstone branch was extremely helpful. I purchased this sub and the Radius 45,90 and 200 speakers together with a Denon AVRX2600H amp and it has transformed our viewing experience. I was reluctant to spend so much on the sub seeing as the old Kef seemed to do the trick. Well, the intervening 18 years or so has seen huge improvements. This is so responsive and it feels much more like a cinema experience when the low, deep, booming sounds come through. I spent more than I had anticipated but I am glad I listened to the advice given. Hopefully this will future proof me for years to come.

Rated 5 out of 5 by from Nice bass and rumbles for tv, movies and music! Bought these to match a monitor audio speaker set. I have placed this towards the back of the room as part of a change of layout for my AV kit as per my wife’s input! The sub performs very well for the role of 70% tv and movies and 30% music. I am not a huge authority on subs, but have setup with a Denon amp and tweaked the settings on the amp and the volume on sub to get it to sound how I like. Bought from the richer sounds store in Bristol as part of a session booked to try out various kit. Overall very happy with the purchase and the sub.

Rated 5 out of 5 by from Modern looking well integrated system Early days for me having bought this sub as part of a radius package. Very happy so far. As with many domestic settings you don’t want speakers to totally dominate but you also don’t want compromise quality. Radius adds style and quality.

Rated 5 out of 5 by from Great but controlled base Bought this in a follow up to a new centre speaker that was so impressive I really enjoyed the surround sound from my system again but that showed up the poor sub woofer from the old system so having already bought Radius 45s and a Radius 200 I had to rush out and but this beast. Base now had great depth but is well controlled and the booming base has gone. Really pleased.

Rated 5 out of 5 by from Elegant and Powerful A well made piece of equipment which is not too large. Produces a smooth deep bass sound. Forgot to switch it on at the start of a film but when I powered it on the sound was transformed. Would definitely recommend this product.
