Subwoofer Connection: Speaker Level Amp to Line Level on Sub?

summadoggie, all you need to do is get a proper 2 way crossover. MiniDSP makes one which is very inexpensive. 

Tape out is not the same as pre out. If you use tape out it will bypass the volume control on the EVO!

On any tape out, that I've used.

Yea I see your dilemma. Do you already own the SVS SB3000?

The LOC would work good too just use the binding post connection you're NOT for you speakers and use that for the LOC.. Easy Peasy, Good idea MC..

It's adding a great option for a very small price.. Can add as many subs as you like. As good as a pre out.. You could add an EQ, DSP, or even a DCX2496 OXO (A)

Thanks for this.  I'll def keep this in mind as I go forward.  

It should be fine if you connect the sub line level rca inputs to your amp speaker blinding posts via a LOC (line output converter).

I had a friend build me a little adapter like the one linked above. Essentially it’s a handful in f resistors in series. Pretty easy. a small price and Bob’s your uncle!

The LOC is nothing more than two resistors per channel. One typically about 10k ohm to drop speaker volts down to line level, and another typically about 1k for load. Here is how it works and what it looks like https://www.epanorama.net/circuits/speaker_to_line.html

This circuit can be anywhere. It can be in a LOC box, or you can do like I did and wire it inside the amp. See the pic on my system page. https://systems.audiogon.com/systems/8367 Also if you can find the circuit diagram of any sub with speaker level input you will see the same resistors are the first thing on the board when speaker level inputs are used.
