My favourite 6.5" midbass

I have used Dayton RS180 for a long time, but those drivers predate these designs by a decade, and have severe cone breakup problems acoompanied by resonance distortion amplification, which becomes audible even as low as 1.5KHz. These SB17 metal cone drivers (this one and the SB17NBAC) are outstanding next generation metal-cone drivers which have these radial ridges to reduce cone breakup. The net result is a low distortion driver with really exceptional clarity and detail in the vocal ranges, something which paper and poly cones find hard to deliver. And all this is done with a controlled cone breakup, thus making it unnecessary for me to use 6th order or Cauer-Elliptic crossover topologies.

These are on the cards for my next MTM floorstander designs, mated to an SB26CDC tweeter or an SB29RDAC.
