Bought the wrong subwoofer!

I’ll look into that. I’ll also be putting it up for sale or trade.

My integrated has only one set of speaker taps. Is ok to connect the converters wires to the same speaker terminals that are driving your main speakers?

The record out does not get attenuated by the volume control.

I can’t return the sub because I bought it from the original owner who also bought and didn’t use it. Also don’t have the box.

i am looking into conversion adapters while also list it for sale and trade.

rec out is not an option as the sub will stay at the same volume regardless of the amps volume setting.

as far as google, I’ve always thought of forums like this as places to seek help and share with others interested in similar pursuits.

There are speaker level to line level adapters. There seems to be some disagreement over whether you need a second set of speaker terminals to connect it to or if you can piggyback it to the same terminals that are driving your main speakers. I think this would compromise the sound of at least your subwoofer if not the mains speakers as well but don’t know just guessing. 

I Sold the SVS yesterday. Going to pick up a Rel Britannia b3. 

The REL b3 may be a 15 year old design but the one I brought home today looks great and sounds better. I was able to get it to blend with my Sonus Faber pretty easily and it truly does disappear from the room. You shouldn’t be so quick to dismiss vintage audio gear. I have owned and enjoyed some equipment almost as old as I am and most of it worked better than I do. I am really happy with my current setup which was put together on a pretty tight budget.
