Hi, I have a pair of Lowther 'TP1' back-horn-loaded loud speakers
with Lowther PM5A drivers. The speakers are around 105db / 1 watt.
(a 1 watt SET valve amp drives them to party sound levels with ease!)
I use a pair of Fostex T90a which came with L pad attenuators.
I found I didn't need the attenuators as the main speakers and the super tweeters are of similar sensitivity. I experimented with different values and ended up with 0.33 mic capacitors to 'roll-in' the super tweeters at around 8 k Hz.
I have the super tweeters wired into the same terminals as the speaker cables and have them facing toward the listener, same as the main speakers.
