mid-treble forward, like nearly everything else on the market.
The question arises as to whether or not studio monitors are truly neutral or "mid-treble forward". I hope not (and assume not), but if so, implies "mid-treble backward" when played through Meridian gear.
This touches on something I've been aware of, and interested in, for some time. I read an interview with Tony Faulkner a few years back (I believe Hi-Fi World, Volume 22 Number 7, September 2012(?) but I can't find it to confirm) where he mentioned using Quad ESLs for monitoring, and my recollection of what he said is that he used these
because they were rather bright and revealing and that if you mix on dull sounding speakers the resulting recording will sound too bright through most systems.
This implied to me that a) recording engineers don't necessarily choose speakers they believe are neutral, b) at least some of them are trying to compensate for lack of neutrality (in TF's case perceived added brightness) in home audio systems.
Personally, with the range of recordings of all genres I listen to, the mixes are pretty much all over the place in terms of balance. This is an issue for the industry and consumer alike - there is no standard everyone adheres to.
I believe the Meridian DSPs to be essentially neutral and accurate, in terms of balance at least, since they reveal the whole range of recordings as they are, from muddy to bright and everything in between. I've had systems in the past which reduce muddiness on recordings but at the expense of being overly tiring and which tame bright ones at the expense of everything being withdrawn.
Since my tastes are eclectic, and not at all about just listening to great recordings, I have to have a system which sits in the middle without being unduly unkind to either end of the spectrum. I've yet to find any which do this better than the Meridians over the long-term.
