PA Speakers

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 MB 208/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.

The PA 110 H is a very compact bass reflex speaker with very linear frequency response and Hi-Fi characteristics. It is fitted with a high-performance 25-cm (10“) woofer, the PAW 25, and the mid-to-high-range DR 45 N, which, together with the HT 21 horn speaker makes for a very resilient tweeter. Separation between the two drivers is at around 1600 Hz.

The peak power handling of the speaker is 250 W. This value was determined in line with the standards using a continuous noise signal. This value is, however, far removed from practice, since music consists of many different impulses and surges. The effective value, that also tells us something about the heating-up of the voice coil, is much lower with music. This means the effective power-handling capabilities of the loud speaker are, in fact, much higher.

The PA 115 H is a compact bass reflex speaker which is outstanding value-for-money. It is fitted with the 38-cm (15“) PAW 38 woofer and the mid-to-high-range horn, HTH 8.7. A special feature of the PAW 38 is that it can generate a drop in frequency response from 2 kHz by around 25 dB without a low-pass filter. As a result, no components are required in the bass section of the crossover, as these would have an unfavourable effect on peak power handling and sensitivity. We decided on a separating frequency of 3000 Hz - a level both speaker drivers can cope with effortlessly.

This value is, however, far removed from practice, since music consists of many different impulses and surges. The effective value, that also tells us something about the heating-up of the voice coil, is much lower with music. This means the effective power-handling capabilities of the loud speaker are, in fact, much higher. We have successfully tested the PA 115 H with a professional amplifier up to the clipping limit, which means we can safely give the music power handling as 500 watts. This output produces a peak level of 120 dB at one metre distance.

The SUB PA 240 was developed to support the PA 110 H. The PAW 46, 46-cm (18“), woofer used here with its large, six-way vented voice coil, is of a design which enables it to work at high output levels and still maintain clear, precise sound. In the recommended cabinet, it manages a very impressive sound pressure of 95 dB (1w/1m) at 30 Hz lower limiting frequency.

The large-format bass reflex tube effectively suppresses flow losses and flow noise. In order to provide the necessary rigidity of the cabinet, a number of strengthening braces are required.
