Hi,

I was at my local Goodwill and found a super cheap X-350 Sub on the shelf. Decided to buy it and realized it won't be compatible with my current system. Before I put any more money into this speaker, I'd like to know it works. Is there any way to test the speaker before buying an adapter?

Thanks!
