An amazing 3-way set which outclasses speakers several times its price.

Very efficient midbass speakers with strong neodymium magnets, the 6.6" MSS6 have an easy to install compact construction, cast aluminum baskets. Carbon-fibre cone with natural rubber surround. Dual type terminals. Leads sewn in the spiders, of course. Black aluminium magnet covers. These puppies are of the very few midbass speakers that excel when installed in true IB, even inverted - fantastic, versatile high-end midbasses!

A state-of-the-art mids which are effectively widebands able to play cleanly above 16-17kHz while packing a punch below 200Hz and able to even play below 100Hz at normal listening levels (not that we recommend it, but it's possible for SQ competition use). An absolute star in the STEG lineup the 4" MSS3 is a fantastic midrange which isn't out of place even in the top tier competition cars. Cast aluminum constructiuon, integrated hex-mesh grilles, neodymium magnets, tapered construction for easy 45 degree installs with minimum space required, very open rear design for easy breathing. Carbon fibre cone.

Right at home next to the MSS6 and MSS3 the MSS1M Magnesium tweeters stand out with amazing detail, complimenting the MSS3 perfectly for a smooth 3-way setup. Premium construction out of machined aluminum, with integrated grilles and sporting 2 included caps - a compact one for push-style installation and a wide open type with 4 mounting screw holes for bolt-in installation. Screw terminals. An absolute top-end gem!

At this level passive systems are a no-go, so no passive crossover networks are included. This set is for active use only. At this day and age we don't recommend any speaker set for passive use, much less such a high-end masterpiece!
