Outboard crossover? Why not?

Those 'many people' could go buy nice furniture that would also happen to play some music. Audiophiles are interested in performance. Outboard crossover would take up more space, this can be a problem for some, just like big monoblocks.

LOL well some of those many people are audiophiles with significant others says a former Alon Lotus SE owner.

Well, those significant others could try and accept their fate and enjoy extra Cartier piece presented in an elegant manner.
But it can be tough, I know.

Hello inna,

The loudspeakers I use, Dali MegaLine III, must employ an active electronic crossover.

Inna,

I’m assuming you are discussing having a passive crossover, that is outside of the speaker cabinet, right?

There are no disadvantages at all, but several possible advantages. I should point out there’s a hybrid approach. In this, there is a separate enclosure just for the crossover components but the enclosure itself appears part of the speaker. I personally like this solution the best.

Advantages include:

• Reduced effects of microphonic interactions with the speaker or the amp
  
• More physical space is available for the crossover, allowing for the use of massive coils and caps which may not have fit otherwise
• Less space is needed for the speaker cabinet
  
• Better crossover cooling, which keeps the crossover’s behavior stable
  
• Since the heat generated by the crossover stays outside the cabinet, the temperature inside the cabinet are reduced which keeps the drivers cooler and are therefore less prone to thermal compression
  

If you were talking about active vs. passive, it’s more complicated. :)

Best,


Erik
