CONVENTION MK IV SAT
Subwoofer satellite arrangements are becoming ever more popular amongst those who simply do not have room to place large-scale speakers or who are unwilling to have large items of furniture around, but who do not wish to go without the enjoyment of powerful, low-range bass. Since low-frequency sounds below 100-150 Hz cannot be located by the human ear, only one subwoofer cabinet is required. The difficulty here is the combination of left- and right-channel low-range frequencies into a single loudspeaker. An uncompromising solution to this is an active crossover unit, which has a corresponding effect on costs. Special loudspeakers with completely separate voice coils make a simple construction of the subwoofer crossover unit possible. If you are intending to use normal bass speakers, a smart trick will solve this problem and kill two birds with one stone: the compound principle. With this arrangement, two bass speakers are screwed together in such a way that they are acoustically coupled via a small air volume. This produces a loudspeaker with two separate voice coils. Despite the relatively small volume in the chamber, very low frequency extremes are achieved. When connecting up the woofers, remember to transpose the polarity on one of them as otherwise the two speakers will be working against each other. In order to ensure the satellite speakers are perfectly matched to the subwoofers, they are vented, too. This enables the volume to be raised at lower frequency ranges. At around 3,000 Hz the ferrofluid-filled textile DTW 95 NG 8 Ohm takes over. A characteristic of this dome tweeter is the "smooth" high-range treatment. If more brilliant high-range frequency output is required, the DSM 25 FFL 8 Ohm with its metal cone can be substituted without altering the crossover unit.
