Why do you need a speaker crossover - discuss

[Dr Bunsen Honeydew]

I use Epos ES14s and the bass/mid has no crossover components in circuit but this is only possible because it is a bespoke driver designed for the specific application. It would be possible to choose a driver and then design a cabinet around it to acheive the same result, given the correct measurement equipment, but even the ES14 is compromised, despite having no crossover, in its lack of sensitvity. You don't get something for nothing.

Exactly, a classic example. For me a crossover is just lazy design, or starting the job arse about face. In large speaker companies it is often "this is the WAF cabinet we want" "these are the drivers you must use as they are at the price point we need" "now design a crossover to make it work"

It is a pity Robin Marshall was only one of a very few who was willing to put in the effort to do it right.
