In my personal experience I have never been able to get the mix right the first time I have always had to do the mix bounce it out to a cd and play it on as many systems I can i.e The car, tv, radio, hifi and pa where ever possible to truly know what is going on in the mix and where its going to be played for the intend end listener
you might ask why go through all the trouble if you have flat expensive monitors well the answer is simple
Speakers sound different because of physics. There is no such thing as a perfect set of speakers no matter what the price. Make a mix where the music is good no matter what speakers you play it on, that’s what mixing is. All speakers models sound pretty much different.
All speakers are designed differently from the driver to the box and as such your mix will react different in different environment hifi speaker are designed to with imperfect wave from to accommodate for the different rooms they will be used in and well as the different mediums
Consumer-grade HiFi speakers are designed to sweeten how the music sounds and they’re pleasant to listen to. But what that means is, the EQ/tone of the speakers are tuned in a certain way to enhance the sound. Most commonly you’ll find these speakers have a lot of extended low frequencies and extended high frequencies.
PA systems are loud and have more bass response as a result I typically mix a less low end to accommodate for the system
PA speakers sacrifice balanced, quick and accurate frequency response for sturdiness and volume
Inherent in the design, is a boost in the midbass, a fairly big scoop in the midrange, and a lack of detail at the very high end.
Headphones and laptop speaker normally come short in low end to with information like “I want a mix the will go on streaming platforms” I will add more lows then what I would for say radio mix
In general, mixing on studio monitors is always preferable. That doesn’t mean that good work hasn’t ever been done on headphones, but it just isn’t all that common. Headphone mixes often lack depth and wind up being very in-your-face and loud
The car stereos let you hear your mix in a whole new way. They can show you problems in your mix that you have not have noticed in your studio. The speakers are designed to make sure you can clearly hear the vocals over the road noises and interference while driving so they’re not as balanced as studio monitors.
Most home-studio owners purchase one good pair of powered reference monitors and that’s it. However, to truly hear how your music will translate to the outside world, the real world beyond the four walls of your comfy studio, you should be working on at least two sets of speakers: your main near-field monitors and a set of small, inexpensive desktop computer speakers (minimonitors).
This dual monitor approach will let you hear how most listeners will be hearing your tracks—over a cheap home stereo system, a television, or computer speakers—instead of the precise, accurate, and “flat” sound of your pricey studio reference monitors.
play the CD on several different audio systems in different rooms and to see what it sounds like. You want to make sure you can still hear the lead vocal clearly and the bass still sounds OK when played on different systems. Its easy to mix on a system that has a lot of deep bass, get one opinion, then play it on another system without deep bass and get a different opinion.
Keep making amendments still you happy with what you have to present to the world remember that where you intend the end listener will help guide you in these small movements
