I will use them for mixing and mastering. The studio is treated with absorption and bass traps (no diffusion as it wouldn't work at my space).
ok, production - this I know... I never comment on pleasure listening as I'm clueless /don't care... I'm up here shopping for quality value-gear for my retiring younger brother and my son that doesn't have nutty money to spend...
these speakers (as a class) are precision tools - nothing more... a mastering engineer recommended k+h mid-fields to me decades ago (told me to, "stop using bad speakers") after I commented on them during a mastering session he was doing for me... he had a pair (among other mfg's) in his mastering room... I ordered a pair the next day - but that's me... so I'll ask you -> have
you listened to them both?...ever?... used either brand before?...
both are fine companies with great spkrs - I use both... hard to make a mistake and it's almost a personal preference... your decisions seem to be based upon their room eq tools... as your room is designed for listening and is treated - my opinion is either eq-sys would likely do the job... but ummm - you're buying a pair of speakers... the MA-1 has been around for a while - the newer MT-48 box looks trick... will that work 'later on' with kh80(s)?... rhetorical question, sorta'...
real quickly - a disclaimer - I don't use either mfg's eq-sys tools... if that disqualifies my opinion - you're welcome to stop reading now... both my first room in L.A. and the studio relocated to where I am now were purpose built studio/control rooms designed from concrete and studs up for recording... control room was built identically to my former location... had it rung-out by a pro I flew in from L.A. - didn't change a thing in the control room... moved a few clouds in the studio...
other than one minor built-in eq setting on the Genelec near-fields - both the Neumanns and the Genelecs run negligibly flat... I was told long ago to get the room built right first... best advice I ever had...
(1) I have no experience with any k+h/Neumann near-fields, only their mid-fields... the opposite is true with Genelecs...
(2) subs and getting the low-end right has always been tricky and most of it is the room itself... tools today are amazing and helpful when you need to null a room - but low end mistakes can bite hard... take the first few projects to rooms you know for a listen - to confirm the software isn't unintentionally deceptive (lying to you)...
side note-> a custom sub-solution designed and built for me has worked for almost thirty years, thru three mid-field swaps-outs - and a move to a new location (with a few minor tweaks)... also, it has tracked well - i.e., stuff doesn't leave here with low-end goofs/mistakes... therefore I don't get yelled at on the phone or lose work...
(3) (as stated above), on my fourth pair of k+h/Neumanns - third pair of Genelecs, - and I switch between them (upstairs/downstairs) while working to check things... they are different (and that contrast helps me quite a lot) - both great products - but you need to listen to them as the
are different...
(4) I have (and still do) swap near-field pairs depending on what I'm doing - typically between the genelecs - a coax pair - and an older task-specific fav pair (mfg names omitted - as that's unimportant)...
(5) when I moved to self-powered monitors over four decades ago they were certainly NOT a standard 'thing' in la-la-land... at all at all... more than a few engineers said wtf? walking into the control room and seeing them for the first time... thankfully k+h had the chops to get them right and keep making them better... when I first signed up to ASR , I was surprised to see Neumann and Genelec had migrated to non-pro use... all good...
(6) my son - in his mid-twenties now and on his own - was audio-spoiled growing up aroung this stuff and wants a pair of Neumann 120 II(s) - but hates the prices...
good luck choosing... flip a coin... then make some music...
