The MB-5B

The MB meets high performance and beautiful design. The MB5-B is a unique slim floor stander with four 5.25” carbon-coned drivers and a sealed ribbon tweeter. The MB5 works as a 2.5-way speaker design, where two 5.25” carbon coned midrange-woofers are supported by two additional Carbon coned drivers for additional base performance. The two carbon midrange-woofers are run in series for an increased and dynamic power handling.

The MB5 cabinet is heavy braced, curved and with solid carbon reinforcements.

The speaker is crossed over at 2600 Hz and the two added side woofers assist up to 250 Hz. The MB5 B carries the base right down to the deepest notes and does that with an effortless drive that will leave amazed.


The internal construction has an optimized airflow which combined with the minimalistic use of damping-material has created a very dynamic and linear low frequency reproduction. The ported cabinet is tuned for optimal impulse response – resulting in a linear, dynamic and detailed low-end reproduction, while at the same time making in room placement of the speaker very easy and versatile.


The woofer and midrange drivers, have been fitted with low loss spider which greatly improves the dynamic capabilities as well as expanding the frequency response in the bass region. – A very nice side effect of this is that the break-in period has been reduced greatly (around 100 hours).


The crossovers are designed for a very linear and natural sound, which is clearly audible throughout the whole line. The crossover has been designed to time-align all drive units at listening distance.

The result is a speaker which not only presents a big and precise soundstage – it also boasts a timing that will make your foot tap and put a big smile on your face!
