Sorry in advance for the length of what follows... I got carried away. Having sold my entire system as part of a house move, I'm back to the drawing board. Quite literally: until the move's complete, all I can do is plan new AV adventures. Mercifully, I've managed to convince SWMBO that we don't need a dining room on top of a kitchen-diner in the new house. So ... the dining room will instead be a snug/small cinema ... and it'll need a sub/subs. I've just sold two USC15s and had resigned myself to anemic bass (or, rather, just less impressive bass). However, now that I'll have a semi-dedicated room again (i.e. not the living room I expected I'd have to use), on the detached side of the house, I'm starting to think all might not be lost... The room's (H/W/D) 225/361/305cm. I've drafted a very rough sketchup (measurements are slightly out). Point A is where the main sub has to go. Room Sim doesn't suggest that this will be a terrible spot (unless I'm mistaken). Point B is where a second, smaller, nearfield sub could go. In both cases the subs would have to be very discrete, as the Mrs doesn't want to see AV (and, frankly, to a degree, nor do I) - so I'm thinking DIY subs disguised as side tables. Questions on which I'd very much appreciate advice, based on a max budget of approx £1000 for the main sub and amp, and less (undecided quite how much) for a second smaller sub, if I decide to go for one: 1. What driver sizes should I be looking at? My priorities are tight, controlled bass and tactile feel rather than sub-15Hz authority. I was thinking 18" at point A, and perhaps 12" at point B. 2. Following above, what drivers should I consider? 3. Is it sensible to have a sub at point B? My thinking with having a sub there is it would add tactile sensation, as well as perhaps address a dip around 50Hz at the MLP (roughly the middle of the sofa) 4. I'm thinking iNuke NU3000DSP - is this sensible? My reason for this is I absolutely must be able to trigger the amp (via a triggered power socket), and I gather the 3000 doesn't thump when disconnected (unlike the 6000). If I need two, that's fine. I've had a fair old read of posts about DIY subs, but I'm a total noob on this front, so if any of the above is misguided do let me know/set me straight. The aim is to start cutting wood in about two month's time, so I've got ages to figure out the best approach.
