The bad thing about all Vandys they don't sound immediate and continue to sound when they should stop i.e. there is a presence of parasite resonances probably due to cabinetteless design. To produce quick and controlled bass the driver realy should be firmly attached to the cabinette and not on the joists as Richard developed. That might work for small drivers maybe. They do actually benefit from higher power, spl and tougher drive despite sounding clean and clear with lower-powered amps(the good thing is their stable load). Whenever I tried to hook them up with more powerfull amplifiers that problem of vibration traces partially dissapeared.
There are number of tweaks possible with vandies but eliminating resonances may cause depletion of their excellent imaging abilities.
So believe it or not, but to my tastes a pair of 1c with a pair of 2wq may even work better than single 3A's in some cases.
