Wilson Audio Specialties Chronosonic XVX loudspeaker!! only $300,000.oo

What a bargain, still bet they sound great with the right amp up them, looking at that impedance/phase angle graph.

XVX is a very demanding load, with EPDR less than 1.1 ohms between 52Hz and 66Hz and between 197Hz and 287Hz, with minimum values of 0.91 ohms at 450Hz and 0.94 ohms at 3250Hz. The Chronosonic XVX should be used with amplifiers that don't have problems driving loads of 2 ohms and lower.
