Using a set of monitors that complete each other is a good idea I agree.
I have heard "Avantone MixCubes" is a good choice for secondary monitor.
They are not ment to blow you away but if it sound goods on them they will translate good on most systems.
Also In general doing reserach on which monitors that does translate best is also a good
idea. Genelecs for instance they do not translate well to other sound system, while it sound good
on them it might sound dull and boring on other speakers.
using analysing tools is good to see problematic frequencies that you might not here.
Yes the avantones seem a good choice for a ''second opinion'' regarding a mix..
I've read and discovered in person exactly the opposite regarding the Genelecs they translate superbly and sound good at the same time, especially the ones that use the ''SAM'' system that fix the room acoustics with a probe for calibration to the listeners position. Maybe your information is outdated? They are very, very serious about room acoustics and the way their systems integrate, a thing other companies don't care..And since I can't hire an expert in acoustic treatment to fix my rented house reflections, options are scarce don't you think?
I know gearslutz bash Genelec and maybe it's where you got that info, but I've listened to some recent models and I was blown away...
For people with limitations regarding, little, or no room treatment, they look like the best option available, what is the purpose of buying a 4k monitors if your room is a shit and all you have is third party calibration options not tailored to your specific speakers?
I was going to chime in as well, but you beat me to it. Genelec are great speakers. They do have more of a modern studio monitor sound than some others, but actually they kind of invented/defined that sound. There is a reason why Genelec are some of the most ubiquitous speakers around. In fact most true profession high end rooms I have been in around the US use Genelecs.
Also I concur that Avantones are great 2nd or 3rd option mix checkers.
I have heard Genelecs and they sound very flat and bulky they sound anything but 3D.
My Trident HG3 is of course better but they have the wideness, the height and the depth.
I would define the charterer of the Genelecs I have tried as "plastic".
I have not tried any of their more expensive speakers, but Genelec are most associated with there
mid range speakers.
There is a few major reason why Genelecs are popular.
1. Good Price to sound ratio.
2. People buy them because of there popularity, they see they are in every project studio out there and for that reason I do not need
to do that reserach I just buy what every one else have and trust their collective "opinion".
3. Genelecs did get popular a lot because of there included room calibration tools that was kind of unique at the time.
4. Also studios want to find the ultimate reference point, and since every one use Genelec it is easier to find the reference point if using the speakers. Just as every one did use the AKG 240 headphones series before.. studios tend to copy a lot of what other studios use...
Before I was building my studio and looking around for monitors I had almost before done any research at all myself decided I should by genelec, i thought there must be a reason why they are so popular and why they are in every project and a lot of other studios.
After doing some research I did quickly find out there is a lot of better choices out there the Genelec.
The fact that they are so well known give them extra promotion and advertising also, I strongly think a lot of people choose genelec just because of pure lazyness really. So yeah I did never end up with the Genelecs luckily , I am very happy for that.
However I would not mind some Genelec monitors in future as a third monitor.
