Peerless BC25TG15-04 1" Silk Dome tweeter.
This was an excellent tweeter that was also priced really reasonably. A low distortion tweeter with very shallow waveguide profile on the face plate that helps gives it a smooth response both on and off axis. It's too bad Peerless / Tymphany decided to shift away from the DIY market.
The On/Off axis measurements were taken at 1v / 50cm (equivalent to 2v/1m - or nominal 1w/1m level).
Distortion measurements taken at 20cm - level specified in measurements
Frequency response measurements are gated at 6ms. Smoothing applied is 1/48th octave.

Final notes:
This was an excellent tweeter that was also priced really competitively. Reasonably low distortion with the addition of very shallow waveguide profile on the face plate that helps gives it a smooth easy to work with response both on and off axis, it was difficult to beat this tweeter for the cost. It's a shame Peerless / Tymphany decided to shift away from the DIY market as these tweeters are difficult to find now.
