<font color='#000000'>If you're looking for a single, smaller speaker with the same bass capabilities as your Paradigms, that's going to be tough. You need the excursion and the radiating area that comes with big boxes and woofers. An alternative might be Paradigm Titans and a nice little powered sub in a 20" cube. If $700 is your limit, a Parts Express Titan 10" will fill the bill.</font>
