Why not put crossover networks in accessible compartments?

@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.

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. 

Some speakers do have a separate compartment such as the Dali Epicon line. Great way to keep the parts out of  direct proximity of the bombastic cabinet. Nola and others use outboard crossovers which add wiring complexity, but totally removes the vibration sensitive parts from the cabinet.

Yes indeed. Stock sand cast resistors that sound relatively grainy compared to the Mills MRA or the even better Path Audio resistors. The Mills would only cost builders some $4 each, but instead they use $ .25-40 cent crappy sand cast resistors. This in $30,000 speakers! Spend the $4 bucks each builders!
