I don't want to purchase a new subwoofer... Need an efficient wireless adaptor to add on to existing sub.
With the least amount of latency of course
I understand you were not looking to buy a new one. I was just commenting on your opening statement that "they should make subwoofers wireless" and I was pointing out the fact that there are models available since 2007.
Both links I gave you are good wireless transmitters for subwoofers. If Outlaw sells them on their site to pair them up with the subwoofers that they sell, should they not be what you are looking for?
