Townshend maximum super tweeters that they sell on Audiogon

My error. I owned the Elac ribbon tweeter. I only evaluated the Townshend.

I currently am using the Townshend on top of my Usher Mini 2 Diamonds. Seems to create a greater sense of space.

It's been a highly enjoyable upgrade. I have a well treated room.

I have been using these with my large Horn speakers for 2 years.  Everything sounds better. Bass, mids etc.  I brought mine to friends 2 weeks ago. They did the same for their Von Schweikerts.  These are not snake oil.  Compared to upgrading cables these make a bigger difference. IMHO.  I run mine at a 3 which seems to be most folks sweet spot.  With my friends VS 4 seemed to sound better with the silk dome tweeters. 

My concern would be with adding another set of speakers which may change the total ohms and thus skew the sound.
