I have a pair of IMF SACMs and I have a pair of IMF super compacts and like the Kefs,the are British speakers and use mostly KEF drivers.I never cared for British sound in the midrange because it was always flushed or hollow.It does appear to give the speaker a sense of depth when you do flush the midrange. I much prefer the ADS as well.

I traded a set of IMF 40's to my brother for a set of EPI 201's that I enjoy. Maybe it was a mistake. The IMF's were harder to place and at the time I was overloaded with stuff.

The ALS-40s always had a hump in the bass we could never get rid of.I believed the 40 used the B-139 oval woofer like the larger IMFs did as I recall.I think you did better with the 201s.IMFs all have too complicated of a crossover and that's half the problem with those speakers.

Thanks for making me feel better. I do believe that the woofer is the one that you speak of. It's been years sense I laid eyes on em. I remember the crossover also had a large parts count where the EPI is just really a 10uf cap on the tweeter. The 201's seem to do okay with a bit of tube power also.

Back in the early 70s thru the mid to late 80s,big SS power amps and receivers that were 200w plus per channel were quite popular among audiophiles.Very few dynamic cone drivers at that time could handle that kind of power. One of the few cone drivers I knew of that could handle it was Cerwin Vega.Now electrostatic and Magenpan speakers could also handle that kind of power,not the ESL-57s but the later ESLs could.
I have always believed that's why they made those networks do complicated because they would eat up a lot of transient peak power and with so many caps in there they would help block the DC rail from hitting the drivers and this turned out to be true.. Notice that once the drivers started to handle more power,networks became much more simple in many speakers.

Interesting. In the end even with the massive amp power increase the SPL output would have been similar with newer speakers.
