can any one give me any idea if this big sub is any good for movies and also for music (half price offer).I listen to music mostly . also will it go with 4 Tannoy MX2 speakers also on offer ,Or i have for the rears some Mission M5DS speakers BUT ive been told this type of speaker is good for movies. BUT no good at all for surround music,? ie the 4 tannoy front and rear would be better,? any help first with the sub! then what will match it best( owhy ) ?would be great thanks. by the way i plan to use a Marantz sr 7400 with the sub and speakers. the sub is available to me for £200 (was £500,) And its brand new.has 400 watt amp, and 15ins driver but i cant find any reviews on it at all many thanks.
