Yeah - the 104 series were excellent. I used to visit a rather anal hi-fi shop in the late '70's which had the motto above the door "Experto crede" which I had to look up - it was "Believe the expert" in latin. Tells you all you need to know about that shop.

But one day I was in and River Song by Dave Grusin was playing through 104's. And I have to say my recollection was that it was excellent. It shows the effect that had, in that forty years later I can still remember what was playing.

But KEF were at the leading edge. They pioneered impulse testing of speakers, and invested what must have been an eye-popping amount of money in the early 70's - an HP computer. This was a 19" rack full of stuff that they used to do FFT analysis of impulse tests, and do crossover optimisation based on the driver FFT responses.

I was lucky enough that my wife Carole (an accountant) was given the audit of KEF - and given the opportunity of buying KEF loudspeakers at a massive discount. Because we were young and did not have much money we bought Caprice II. And enjoyed them for five or six years. Wish we'd been flush enough to buy the R105's!

Does he stop the grandfather clock collection when he's listening to music? And even if stopped what about the chime resonating?

I went so far as to use a swept sine in my room to identify what was in there ringing along to the music. And moved offending items to another room.

From Nelson Pass's description of a monster transmission line subwoofer

"Funny things happen when your speakers are flat to 13
Hz. You have to be careful about your tone arm, your
windows, your neighbors, and your bowels."
