Any speaker you put on your credit card and then fail to make payments for. ( just thought this needed a little humor).
Of all the speakers I have owned , my current speakers, Wisdom Audio D-75's and prior speakers, Waveform Mach 17's both do an excellent job. Both use active crossovers and the Wisdoms use a rather large Planar panel for 120 Hz and up. Most of my electronics are Audio Research tube gear. VPI-TNT and Wadia Digital
