Hello, pretty much as title says: i want to buy a new subwoofer (possibly Yamaha NS-SW100), which has rca input only. My receiver (amplified) has only speaker level wires flowing out: how to connect them? Thanks!
 
Just saw this thread so maybe I can clarify things.
The Pioneer has a powered subwoofer ( or .1 )output meant to be used by a passive subwoofer. You can get a passive sub and cut the end off the wire at the sub end. It will have two conductors.
If you want to use a self powered subwoofer some of them do have speaker level inputs that you can connect the same way you would the passive.
If the self powered sub only has line level inputs then a speaker to line level converter will work fine. Have used them many times.

Thanks for your answer. My system is an old pre-made Home theater Pioneer S-DV222 (old dvd with 5.1).
I found adapters/converters digging, but they all seem to be for car audio, not sure if it's the same.
I'm looking to replace the original sub becuase it squeaks.
I could replace the receiver too, but they start from around 200? I'm on a budget

So it isn't REALLY a receiver, it is an all-in-one. That limits the options. The pictures I see of that unit show a line-out 1 on the back. You can try that first. It looks like it was setup for a tape deck to be added.

The problem with that is it's not a dedicated sub output. Really need to use the ".1" output as that's going to have the dedicated sub channel. And for some reason it uses speaker wire?

I assume you already have the sub? Can you get a different one? Stick to something that is compatible with what you have.

No it would be full frequency, but most powered subs have a low frequency filter in the RCA input line.

Thanks for the reply. I still have to buy the sub, but unfortunately for a budget amount I can't find a sub that has the same connection (speaker wire). Also i'm in Europe and seems like there's different availability of makes and models than US. I'd go with another sub for a budget price, with speaker wire input, if I could find one.

Ok, I just checked and that out has 2 pins left and right. I'd need to use an adapter to make the left-right into a single rca then, right?
Also I should add that the subwoofer I was looking to buy is a Yamaha NS-SW100

I don't think it's blown... It's always been cheap and low quality, some films with poerful bass it can't handle them. I just wanted to get a new decent one, on a budget of < 200 euros

The speaker would be a big part of that. Any low pass filter would be another part, and of course the case/porting inside. But if they used a super weak speaker that would be why it craps out during heavy bass scenes. I'm not even sure how easy it would be to get inside the unit, but if it is I'd consider just wiring in a new woofer.

I've been digging and it seems like my best option, besides buying a new proper receiver, or a high level sub with many different inputs, is to get a high/low level converter (basically speaker wire to rca). It's just weird that i'll have to wire the speaker wires coming out of my Pioneer to the converter through a morsel or something.

The Pioneer has a powered subwoofer ( or .1 )output meant to be used by a passive subwoofer. You can get a passive sub and cut the end off the wire at the sub end. It will have two conductors.
