I am currently using the Paradigm PDR-10 and thinking of upgrading to a more powerful sub. These are what I have in mind: Defintive Prosub 80 Definitive Prosub 100TL I am leaned toward the 100TL as its using a 10" cone (same as my current sub). Both are rated at 250W RMS, thus, should be an upgrade over my 120W one. My main purpose of the sub is for watching movies. Also listen to classical and ocassional Jazz. Are there any other brands you folks would recommend over those 2? I have also heard that British subs (no offense to Brits) don't produce as much bass compared to American ones. The Brit subs are designed to blend nicely with speakers to produce natural sounding bass, not those strong booming type meant for movies. Thus, my impression is that Brit subs are mean for HiFi and US ones are meant for movies. I did audition the MJ Acoustics Reference 100 before (since its a Best Buy by What Hifi). However, I don't quite like the bass. It doesn't go as deep as my PDR-10 and doesn't produce much "boom" in movies. Thanks for your help!
