Default Radford crossover problems

Why not bi-wire direct thus by-passing the crossovers altogether?


To do this you would need to ensure that:

A) the crossover point and order were correct. (Fairly easy)

B) That any effects due to impedance interactions between the drivers and
original crossover were taken into account. (Harder without detailed
knowledge of the original crossovers.)

C) That any use of the original crossovers to alter the in-band response
was also taken into account (inc B). (Also hard without the required
details.)

Thus you may need all the details of the original crossover in order to
arrange for a suitable active crossover as a replacement.

For obvious reasons, simply bi-wiring with no crossover or filters at any
point would probably be unsatisfactory.

Slainte,
