I have 3 LPG 26NA 1" metal dome tweeters for sale. One is brand new, fresh from madisound. The other two are used, but very gently treated. Crossed over at 4.5 kHz with 24 db slopes. The used tweeters come with the LPG hinged wedge mounts, which are removable. $40 shipped for the used pair, $30 shipped for the BNIB tweeter.
