CM... you need to talk to Mark Seaton. you really do. his ability to come up with custom stuff is almost without equal.
As far as some of the more out there comments...
you say speakers are about personal taste, hold it right there. I am sorry ANYONE CAN HEAR A CLAW SKREESHING THROUGH A BLACKBOARD.
And taste equals opinion... and everybody has one. the only FACTS that are out there are measurements. so your hyperbole is only your opinion. if you care to show a ream of measurements demonstrating superiority of one over the other, then a Fact would enter your discourse and of course the rest of us would fall down in shock.
synthesis can be very close to that, the Genelec are far from that but not that much, not far enough,
Again, opinion. opinion that obviously shows a hearing issue.
You say it is about taste I say it is about aversion to sadomasochism. Genelec's are not nearly as transparent as Dynaudio's. Transparency=low fatigue factor (the opposite of a massochistic experience).
Again, opinion. one that proclaims to know all there is. all these things we talk about with speakers are purely opinion. your throwing around a few press releases that a few groups switched form one monitor to another is nothing but some marketing. so BBC switched in some room refurbs... who cares. as it has been stated, in 5 years they will switch again. And guess what? somewhere somebody has switched out some Dynaudios for something else yet again.
And has been echoed many times here. there have been evolution in all speakers in the last 20 years. the only real revolutions have been in the areas of room processing and DSP and class D and T amps. A well designed cabinet from 20 years ago is still a well designed cabinet. now it is true that with modelling software we can make more efficient cabinets, and get more out of a smaller package, but it is still the same sound range getting to our ears that we need to do.
One other area where revolution has happened is the acoustic modeling software. THings like Ease and Lara. what they can do to model a room and design ways to ensure coverage and avoid reflections is amazing.
And hey, if you want lots of punishing bass... just build a sub line array. Lots of people did it (unintentionally) over the last 20 years. they are killer if you are in the hot seat...
