Connecting a sub which way to go


I have a NAD165 Pre-amp and a Nad 365 amp I am connecting a SVS SB13 Ultra into the system. The 165 has a sub output,but is it better to use that or the signal between the pre amp and the amp stripping off the bottom end signals say 15HZ to 80 sending rest on to the amp?  The SVS has both a high pass and a low pass filter. The rest of my system is Paradigm S3 V2's and Triad Silver Monitor's

This is about the wilfull spreading of inaccurate information, not about Paul McGowan as an expert. REL doesn’t control the subwoofer market. I’ve tried their products and was unimpressed.

I have tried it both ways. As I see it, running the sub from the preamp out while running the mains full range is the way to go. Why? Just think about this ... the internal crossover in a sub probably uses fairly mundane capacitors. The crossovers in your speakers are likely far superior, such as in my case, where my JA Pulsars use the Modafferi crossover. By using the sub’s crossover, you are taking the signal from superior capacitors in your expensive preamp and forcing it through a mid-grade capacitor in the crossover before it is sent to your amp. That creates a sonic bottleneck, and actually degrades the sound. While there is some truth to the idea that running high pass through the sub alleviates some of the load on the amp and speakers, I think that placing the sub in the signal path really diminishes the sound overall and prevents you from hearing what your components can really do in synchronicity.



I agree with the last 3 posts.

Full range and cross the sub over low.  55 hz or lower.  Play around with sub placement.

Awesome speakers and sub btw.  I had a pair of S2 V3’s... don’t ever get rid of those; seriously
