How to connect susb to my system


Hi there,

Can you please help me on the correct way to connect a pair of powered subs to my system?

My system components:

Audio Research Ref 10 preamp

Rogue Apollo mono amps

Evolution Acoustics MM3 speakers.

Thanks in advance for your help.

Then you can either chain them in between the amplifier and the speakers (using speaker cables)...

OR...

Plug them into the back of your preamp via the RCA/XLR connections.

Using the RCA/XLR connections will maintain full range sound to your speakers.

If you chain them in via speaker cables, most subs (you haven't specified what you have) will play the sub-bass and then pass the upper frequencies to your speakers.

@leog2015 , I looked up that preamp, and it appears you could use a set of the "main output" xlr’s to the subwoofers.

Very nice system, by the way.

Let me know when you get it rocking. You may have to turn on the output in the preamp, I don't know...

@soix ,

If he uses the preamp to connect the sub off of an additional "main out" on the preamplifier, the speakers will still receive the full range sound from the amplifier. (the other "main out" from the preamp goes to the amplifier, which powers the speakers...)

If he uses the speaker connections and chains the subs in off the amplifier, I would expect the subwoofer to filter the signal. Subs get the bass, and then anything above the crossover point on the subwoofer amplifier should be sent to the speakers. (Meaning, the sub acts as an inline crossover. I am aware that not all subs do this, but most do.)

Just trying to clarify.....
