[QUOTE="Hennie, post: 9357, member: 20"] If it's a B200 then it has a Bextrene cone. Bextrene cones suffered from significant breakup resonances in the passband requiring heavy damping with some goo. Despite this, they still required an RLC suck-out circuit right in the midband. The result is a bit flat sounding with reduced dynamic contrasts and a pretty obvious Bextrene colouration signature. Still, many commercial designs used the B200 up to 3kHz. Crossover design would be challenging though. A think a 3 way design with a 4" mid cone driver might have some promise. How about doping a Soin or Infinity Dynamic 4" paper cone if you want to keep costs low. Even a low cost polycone midrange driver might outperform the B200 in the midrange. [/QUOTE]
