Adding Subs to a 2 channel system. Wiring advise

@soix ,

Thanks for the positive feedback!

One of the main reasons I post is to help those who aren’t ’savvy’ to things audiophile. I was lucky to have been able to audition equipment during the ’80’s, when brick and mortar stores were easily accessed.

I know the value of being able to listen in a listening room. When I see a ’newbie’ post, I want to help guide them to making the best informed decision.-One that will minimize any future regrets.

The Vandy 2wq subs are a great buy. Like all Vandersteen products, they are built like tanks-Even 2w subs, now over 30 years old work as they should (how many REL or SVS subs can make that claim?).

IMHO, you would save yourself a lot of effort if you bought a Vandersteen Sub 3.

This route isn't 'cheap', but it provides an easy and seamless way to integrate your speakers with the sub. It also allows you to dial in the sub with an equalizer-which no other sub manufacturer offers. (You do need to purchase the Vandy high pass filter). Though other manufacturers offer low and high pass filters, Vandersteen uses 1st order crossovers-which minimize time and phase distortions that occur using higher ordered crossovers.

If this doesn't work for you. There are other ways to 'skin the cat' 

Using other subs, the 'recommended' way is to use the speaker output to drive the sub. That way the signal is the same to the speaker and the sub, so you will be able to dial them in 'easier'. (You need a second set of (speaker) cables to connect to the sub, in addition to the set going to the speakers).

The other way is to use an aux preamp output to the subs. This works well, at least for me. (And, you will need a second set of cables (interconnects), to go from the preamp to the sub.

Mind you, this is dependent upon what the sub you choose offers in the way of connectivity.

In the 'no free lunch' category, DSP has limitations. You can introduce time/phase delays/inconsistencies.

YMMV.
