This is a pair of rare VMPS rear ambience or super tweeters. They were designed to be useful on many speakers, not just VMPS. They use a circular planar tweeter that sounds much like a ribbon tweeter. I believe Genesis used this tweeter in their high end offerings. This is encased in flat black blocks, and they have an internal x-over. I think they are crossed over at 10khz., and are padded down by 10 db. Optimized to be mounted using foam tape to the back of speakers, they add air and dimension to the sound without being audible otherwise.
Very nice effect. They can also face forward where they add extension to the top end.
They simply connect to the main speaker terminals. Wire is 14" long and is silver clad copper with teflon dielectric, with spades. They are in perfect condition. Shipping by USPS to cont. US.
Thanks for having a look!
