Mixing Monitors

I know the basics and all but should I really be spending hundreds of dollars on bass traps and shit? my room already has a lot of things that will absorb and help stop reflections in my room but what are the most important things to consider as far and the placement of the speakers go? for some context I have a rectangle room thats about 12 x 20 feet

yes, split your budget 50/50 between speakers and room. DIY makes things cost efficient

room size and position of the monitors.

How big is your room?

shit didn't read that last sentence lol.

You want your speakers face in the direction of the longest part of your room. You only need a bit of foam on the sides of your room to capture any bass that is being reflected. Stick to a pair of 5in cones and you shouldn't run into too much mud issues.

the speakers listed hereshould be good enough.

Also looks into a pair of adam a5x's.

Sound on Sound is a great resource for this. They have loads of info on basic treatments (mirror points etc) and a series where they go out to readers houses and solve their accoustic/monitor placement issues

this is my current layout

jbl lsr305

This is what you should be aiming for

I specifically listed eve and hedd because they're next step up from adam, it's where all their former r&d department went. adam is pretty much dead

yeah but you can probably find a pair of adams for cheap FWIW
