Thanks for previous replies on the subject, but Im still struggling to find the right system. So to put together my thoughts. 1. Several people advocate the use of a satellite speaker system and a top flight sub woofer like the SVS plus, Velodyne dd 15 or something like the B&W ASW 750. 2. Several people that own subs in that range have augmented them with smaller subs to fill in the 'gaps' at around 30Hz 3. Some people have returned to a floorstanding full range speaker and have turned their backs on the subs. 4.Most people dont seem to think THX speaker packages are worth the trouble. 5.Several people use a smaller (lower quality) set of rear speakers and are quite happy because they are less visible and usually cheaper. Others seem to think the rears need to be at least as good as the main fronts. 6. When I look at most of these satellite set ups, they seem very expensive for what they are. The Anthony Galleo spheres are just tiny full range drivers that seem to cost anything between £200 and £400 each, but you can get a set of Dynaudio bookshelf speaker with 2 drivers/crossovers etc for around the same price. So in essence I need a system for cinema only, this includes the odd concert DVD. As yet I have not decided on which new amp will be purchased. The room is around 20ft long and 16 feet wide with 8 foot ceilings. I dont want to have several sub woofers to fill in gaps in the frequency range, but I do want seismic events to feel that way. Also great mids and mid bass for the musical side of a film score would be welcome. Its more important for the whole system to gel, rather than just concentrate on the extremes. Budget would be around £1500, Stands and cables would not be included in this figure. 5.1 is fine. Secondhand is preferred. Any ideas ??
