Why not put crossover networks in accessible compartments?

Thank goodness the dismal science doesn't rule everyone.

I believe a lot of these manufacturers would not have the crossovers accessible on purpose to hide the cheap parts they are using. 

Living Voice is another company that uses outboard crossovers. Other benefits beyond vibration control include...

- More room for proper spacing of inductors.  Far too many speakers have them jammed together due to limited space and this negatively impacts the Sonics as they interact. 

- Some of the better parts are just plain huge like PIO caps and heavy gauge, air core inductors for bass drivers. They won’t fit in the cramped internal speaker cabs. 

Volti Audio is another.

@mofojo . It does amaze how many, if not most, speakers that retail for up to $30,000 use $ .40 cent resistors and $7 capacitors. I mod and upgrade speakers for myself and clients and see this all the time. The sonic gains realized with a few well chosen and implemented upgrades is shocking.
