The Devil Columa 300 Mk2 provides a whole lot of home theater experience for your money. The four aluminum columns speakers and the centers are optimized for use in living rooms and provide a very impressive sound experience. The sound can be perceived both at high volume levels, as well as in clear as a bell room volume and always differentiated. Even at high volumes the sound never sounds tinny or rattling. I really had to say before a home theater system from Bose, with whom I was very satisfied, and will have, the Teufel system sounds more harmonious and better coordinated. A great surround sound experience, whether you want it times really loud or in a quieter atmosphere. The processing of aluminum is high and raises no complaints. The absolute highlight is the powered subwoofer, which has a whole lot of power reserves and accordingly can work impressively. Its impressive dimensions should be agreed in advance but definitely with their own partner, since he occupies a lot of space in the living room and very visually stands out. I run the Columa 300 Mk2 together with a Denon AVR 1713 and find this combination of loudspeakers and amplifiers optimally. Both blends well with each other and generates great, powerful home theater sound.
