I currently have a Sony 23W powered subwoofer (6 5/16 inch speaker, cone type) along with a Bose passive woofer (connected to the accompanying Bose satellite front and center speakers). The Sony has a frequency range of 28Hz-200Hz and a high frequency cut-off frequency of 50Hz-200Hz. I am not feeling the base frequencies like a really good sub does so I want to upgrade my Sony, but I have a limited budget ($100-$200) so I cannot get the high quality ones commonly talked about in this forum. I saw a Panasonic sub on 6ave.com on sale in my price range (site says it retails for $150). The specs for this are below: Frequency Response: 32Hz-350Hz-16dB 1 Way - 1 Speaker System Bass-Reflex Type Amplifier Power: 50 Watts Dynamic Power What I want is to FEEL the base during an explosion, not just hear it. I realize that this probably isn't realistic in my price range, so any recommendations on other models/brands that might approximate this goal are greatly appreciated. I would like to know what specs I should be looking for to help accomplish my goal (i.e. is it just the size of the speaker, amount of wattage, ect?).
