Tiny mags...My cdt 61a's dwarf those things. Of course it's not like you can tell much from magnet size. All i know is I bought a set of Boston SL60's a while back thinking they would be as good, or slightly better than my CDT's, and those things sucked. Magnet looked almost just like that. Set them at anything below 100hz, with 110w of power and they would sound like popcorn popping. Ended up keeping my CDT's up front, and using the Boston's for rear fill.
