Hello all gurus of sound, I have recently moved all of my theater equipment into a dedicated room. The wife said yes because my first child is due in 3 months and we needed the living room to be baby ready. I have finished all of the lighting and furniture and finally completed the electronic install tonight. Here is the question. The room is 12x12 and suprisingly the sound is quite nice. I expected quite a bit of sound wave chaos but the addition of fabric and furniture have made the room warm sounding and pleasingly flat. My equipment list is: Yamaha htr-5540 Paradigm Atoms all the way around Sony sa-wm40 sub Panny 51" hdtv Toshiba sd-4800 dvd Given my room dimensions and the fact that it is small would I notice a large difference by upgrading to an SVS sub. There is more than enough LFE from the Sony and it has quite a good reputation as a great budget sub. I just am worried about the bass becoming too much for my small room with the svs. I am growing leaning toward the svs however because of all of the great reviews. Let me know what you think and thanks in advance for all of your suggestions.
