Sold: ALK ES5800t Crossovers (Bi-amp version)

Recommended Posts

These are the bi-amp versions of Al's ES5800 crossovers.  They split the high pass signal, sending frequencies below 5800 Hz to the squawker and frequencies above 5800Hz to the tweeter.  I had Al modify the ES5800, eliminating the tweeter autoformer and moving the squawker autoformer from the ES400 to the ES5800t.

The idea behind the design is to attenuate the squawker to match the tweeter, then adjust the gain of the high-pass amp to match the low-pass amp/woofer SPL.

 

Although these are designed for an active bi-amp system, I have also run these fully passive, using an simple inductor/capacitor network ahead of the ES5800t. 

 

$320 shipped to the lower 48.

An example of this setup.  The resistors are there for testing only 😎
