The Rogers LS7 speaker usually shines in reviews, as it sounds highly accurate and clear, but does not lack strong depths at the same time. The LS7 speaker was manufactured by Swisstone Electronics Ltd. and sold for 265 Pounds at the time of its release.
The speaker was available in black and teak walnut veneer. Under the veneer, the cabinets consist of 12/18 mm MDF, not of Plywood. The LS7 is a 2-way reflex system and is designed to be stand-mounted and has an internal volume of about 30 litres. The two speakers are a 25mm soft dome tweeter (Celestion T1001) with a protective cover and a 200mm bass and midrange speaker with a polypropylene cone. The sound quality of the Rogers LS7 is highly accurate and according to a variety reviews (see links below) the coloration was very low.
