Very interesting , my aproach for what iit's worth , it probably has some flaws.
Damping the room enough to,get rid of flutter echo ( the garage / cave sound ) using some odd bits of acoustic material , mostly behind me I'm sitting close to the back wall . Use digital room correction for the bass , built in DRC in my pre-processor . Speaker placement L,R placed at 1/3 and 2/3 of the lengt of a long wall in my rectangular room 1/5 of the depth out in the room. Some fine tuning by ear mostly the angle inwards the listening position . Centre is in the middle but at ear high when I'm sitting in the sofa ,65" plasma above centre speaker . Many have the centre very close to the floor this sucks midrange gets really coloured . I listen a lot in Meridian trifield mode actually using all 5ch for stereo music . Subwoofer at 1/5 of depth and length not in corner , probably a waste of capability but excites less modes . Low xover frequ to sub 50-60hz using the pre amp processors fillter . Note sub is also filtered by the DRC ! This i think is essential for good one sub integration the DRC makes it really gel together . But xover must be at low frequency and main speakers must be able to reproduce some bass . Xover filter must be steep I don't think you can integrate to small main speakers with a single sub xover would be to high and you need 2 subs close to the speakers , in many cases I've heard the xover is a bit on the high side and sub still has audible contribution at 2*fs and as the sub is not perfect it also does other things like port sounds . It still not perfect but very good but even better bass I need bigger main speakers and 2 or more large closed box subwoofers :) I imagine there is a lot of improvement to do to my aproach :) Where is 1/3 coming from ? I noticed that many speaker placement softwares simply suggest a grid of positions at odd multiples of room dimensions they often has 1/3 near the top of the list . There is quite a lot of them so it may be hard to try them all manually . But a room has many other constraints it's a living room with furniture and doors opening and windows , this often means that the side of the room where the speakers will be is " given " and possibly also where the sub will be . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
