I remember seeing the dB100's when first introduced at CES yrs ago... Wavelength amps were driving them I believe.. All dressed in black cloth, the 100's sure sound terrific... The only BIG problem was their appearance,,, big coffins set up in your living room could leave you "terminal"! The db99's soon followed and their was no looking back... The 99's were/are stunning,, they were released in terrific Wilson like finishes in a variety of colors.. Used with my Wavac SET and later with sweet VAC amps,,, I had sellers remorse when I let my pair in Af Hazelwood with black woof drivers go... Jack
