Under the brand names represented in this comparison, the Saarland traditional Backes & Muller should enjoy the greatest degree of familiarity to Hi-Fi friends. Here, the brand benefits from its long-term presence and a sales structure that is tailored to the wishes and needs of private customers.
With her round cheeks of the wood and the satin baffle highly stable, artificial stone, the BM 2 acts as dignified as unobtrusive. First, a look at the back suggests that behind the untechnical facade is a professional, equipped for all types of installation monitor.
Input signals will be Studio-typical balanced, also the so helpful in the narrow ob van or installation close to a wall place filter are available and can be operated without tools. Two conservative, sonically superior analog amplifiers with a total output of 250 Watts are used as drive, the crossover is not digital.
The BM 2 is different from their competitors not only visually, but also some constructive peculiarities. Such as at the tweeter, where Michael is the only box with soft fabric dome tweeter.
While ADAM and Geithain put on a bass-reflex system, say on a part-open housing with air tube to the optimization of deep bass behavior, the Backes Cabinet is completely closed.
Behind the 20-centimeter carbon fiber cone of the woofer is an accelerometer, which captures the movement of the diaphragm and reports an upstream stage of regulation. It ensures the necessary impulse precision, coupled with a depth that only bold stand boxes or separate subwoofer.
The border up to the down, the BM 2 delivers sound pressure, varies between 30 and 48 Hertz. So the user can weigh what is more important to him: maximum depth or higher sound pressure reserves.
These two mentioned, often delicate for such compact boxes properties get the BM 2 in downright magnificent way. A corner of deeper and in extreme cases even louder went into this round only the Geithain; This achieved but not the velvety serenity of Backes, who was bought to the delight of the tester with loss of detail or vitality.
Tonal played all three at the highest level, and so it was less to do with a better or worse as rather to fine character differences and personal preferences in this regard.
So, it was regularly within the three-way discussion the Backes was judged especially around sounding, the violas and cellos was awarded the most body and settled the  most velvety WHIR violins. From the standpoint of the consumer the feeling of happiness was clearly most at her.
