Installation and cabinet guidance

Allow a 190 mm cut-out for a frame that measures 222 mm across and stands 6 mm proud of the baffle. Behind the panel the driver needs 89 mm of clear depth, which covers the 188 mm basket body and the 120 mm magnet, and room beyond that for the terminals and the wiring. Six 5 mm fixing holes sit on a 210 mm circle, each in a 9 mm seat.

The driver weighs 2.5 kg, so use a rigid, well braced baffle and a continuous gasket or sealing strip between the frame and the panel. Tighten the six fixings evenly and only enough to seal, so the cast frame is not distorted. With ±10 mm of travel available, check that the cone and the rubber surround stay clear of the grille and of any internal bracing at full excursion.

The terminals take 4.8 x 0.8 mm blades on the positive side and 2.8 x 0.8 mm on the negative, so blade size identifies polarity; observe it on both coils. Three wiring options are published: one coil connected and the other left unused, which gives 4 Ω; both coils in series, which gives 8 Ω; and both coils in parallel, which gives 2 Ω. Choose the option your amplifier is rated for, and note that the 2 Ω parallel connection asks the most of it.

Visaton's published enclosure suggestions for this driver: 30 l bass reflex with a BR 25.50 port (fb 40 Hz); 50 l bass reflex with a BR 25.50 port (fb 31 Hz); 70 l bass reflex with a BR 25.50 port (fb 27 Hz).
