Sorry Joolz I missed this .

I think its mostly about the power. 45's deliver a very sweet 1.8 watts, but the 211s push out about 20 watts and always give the impression they are 100% in charge. They are slightly less sweet than the 45s, but make up for it in reserves of drive.

I generally compare a mini and a Roll Royce at 70 mph. Both are very comfortable at that speed but the Rolls Royce performs in a much more relaxed way.

Thanks Chris,
I think that's a very good analogy, and bears out what i believe i have heard.

I am in the process of rebuilding and hopefully improving my open baffle speakers. All changes are reversible if it goes awry.

1. Out go the Saba 8" Greencones to be replaced with SEAS Alnico W8 drivers. These are so good that I have done away with upper and lower crossovers so they run full range. There is an additional bonus for SQ by removal of the passive crossovers.
2. Out go the Grundig 4" Alnico high frequency drivers to be replaced by Klangfilm Alnico 4" drivers. Comparison of their weights Grundig 330g and Klangfilm 555g, roughly reflects the improvement in SQ.
3. The mid and high frequencies are left exclusively to the 211 triodes and the 15" Altec Alnico drivers are fed independently by an ICE amp (1000ASP) through a MiniDSP to set the low pass filter and equalisation. They seem to be best crossed over at about 100Hz so not far off being subs

Tuning is ongoing
