I have (hopefully) now sourced a 2nd D1500 - I plan to try it as per VK's suggestion. This has however got me thinking about my next move............
Is it possible to run (DSP) stereo subs with the xover in the processor with another (analogue or DSP) sub handling the LFE channel?
Can a room be over woofered relative to the other speakers? (mine is 5m x 6m) - a m2500 just failed to sell at �400 on the bay which is partially motivating my musings.
Is another pair of DSP33's going to give me a better 'bang for my buck' than more subs?
