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


Hey there.  Are there any real problems inherent in running a signal to a sub (SVS SB-3000) from an integrated (PrimaLuna EVO 100) - from speaker level on the amp to line in on the sub using an adapter?  Thanks!

This:

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).

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)
