Visaton MB 208/H - shown assembled with suggested cabinets, not supplied.
Characteristics and Sound Properties
The MB 208/H is a compact, high-output speaker. It is equipped with two high-efficiency 20 cm fullrange BG 20 - 8 Ohm 's, working in parallel, and the HTH 8.7 - 8 Ohm tweeter. Apart from being ideal as a monitor speaker for vocals and instruments, in smallish to medium-sized rooms, it is also a good candidate for combining with a good subwoofer (e.g. MB 115/B ) for larger PA events.
As a result of the d'Appolito arrangement, less sound is dissipated upwards and downwards. This directional advantage reduces the amount of ceiling and floor reflection in large halls, and will result in better voice transmission and less tendency to feedback. The sound quality of the MB208/H is extremely high. The sound imbalance often experienced with musicians systems is missing here. In conjunction with the MB 115/B, there is no reason why hi-fi sound quality should not be achieved.
The compact design makes it ideal for transport.
Extract from Hobby HiFi: "Verdict: This combination of 208/H and 115/B provides excellent sound properties at hi-fi level, and with masses of dynamic power in reserve. Thanks to the high efficiency level, even a 100-watt amplifier will provide the enough power - calculations show that this would produce a maximum output of 113 dB, even if a more powerful booster will make even more sense of both the satellites and the bass."

Assembly
First, cut the openings for the drivers in the front panel. The boards are then simply glued together (butt-joints) as shown in the parts list, with the front panel set back a little. The crossover is attached at the rear of the cabinet behind one of the bass vents.
Internal Damping
The damping of the cabinet uses two mats of damping material rolled loosely and pushed into the cabinet through a bass opening.
