Sorry , but for my money I'd buy the British built ATC SCM50 SL passive classic series speakers, for 20K.
not for mine...
@echoz hard questions are absolutely allowed, and welcome... though convenient and good answers may be hard to come by the following review may help a bit... as i mentioned earlier, the modern iteration of the spendor sp100 is the closest analog to the ls5/5 by graham, minus the vertical face slots... (i currently have the prior gen sp100 r2 and i had the mon 40.1 in the past, i would say this review is reasonably on target) http://highfidelity.pl/@main-1106&lang=en |
the reality is, all these are tip top speakers in the bbc heritage, produced by two of illustrious current producers thus in a good setup, with proper accompanying componentry, good room, any and all will sound brilliant (save the mon 30, which will still need low bass support from sub(s)) op has asked a hard question - which is how two such competing 20k+ speakers sound different each other - and we all know there is only one way to really know... (even competing displays in different rooms in a high end show wouldn’t answer that question properly) |
op the harbeth mon 40 series has always had a forward (but excellently detailed and nuanced) midrange... it is characteristic of that speaker, despite it huge size and excellent capability also in the treble and bass regions @tobes you can search bbc ls5/5, there is plenty written about the bbc speaker development program that created the various models... see link below for the seminal white paper written on the ls5/5 design... the cabinet slit is to manage horizontal directivity, but like any other design choice, it comes with tradeoffs (sec 4.1) http://downloads.bbc.co.uk/rd/pubs/reports/1967-57.pdf the nearest relative to the ls5/5 is the modern spendor sp100/classic 100 series |
