After much deliberation and reading various forums, mostly being influenced by the thread 'Finding a Sub Driver?' on this very page, I've finally ordered myself two Shiva III sub's for my room. They are going in two 95ltr enclosures ported at around 20hz, and also porting into each other at around 30hz, which is something I have been experimenting with that seems to let each driver 'see' a bigger enclosure that it is really in. I've taken a big risk by building the enclosures into the floor with the drivers facing upwards, sitting slightly below floor level to allow a grille to be fitted. Should be getting 150w RMS each from an Alesis RA300 power amp, unless I can find something a bit smaller with about the same power at the same sort of price (£155) I'll post some pics of my room when there is more to see.
