A 6.5 inch diameter subwoofer. Not a midwoofer, not a HiFi driver, this is a woofer that has gone through Wonka Vision and shrunk! Well in truth it is a dense spud of a cast chassis with a massive rubber-armoured Ferrite magnet on the back and one hell of an Aluminium piston in the middle with lots of suspension. Fully three layers, with a really big genuine rubber (not foam) top suspension and dual linen spiders beneath. The terminals are fit to accept a smallish wire and are a screw type that you will need a precision tiny screwdriver to use.
The power handling is prodigious, for its size, as is the travel of the cone. It needs a small ported box and requires a steep -12dB per Octave subsonic filter at around 30Hz when boxed. When played ‘free air’ (as I did in the test rig, really) it should be subsonic filtered at 50Hz.
