Vandersteen Quatro are way under $20k and have a fantastic built in powered sub with 11 bands of analog EQ
and are phase and time correct with pistonic drivers
a pair of 5a ( no longer in production ) with push pull aluminum cone subs are around used for $8-10k
the 5a carbon is still in production
all the bass amplified vandersteen products come with very carefully engineered hi pass filters and correction for the built in sub amp
