Oh yeah.. I'm fan of cutting my hole to the width of the studs.. way easier to have the support there when it needs to be patched. In a previous career, I did low voltage, basically home theaters and automation... I would do my best to avoid doing my own drywall work and foolishly when I did open up walls I was cutting small holes which then would make the job extra hard both to run my wires and to patch 🤣. There was one remodel project that I straight Swiss cheesed that house up... It was a large project for my company (9k sqft house) and 100% retrofit.. I was using one of these https://www.amazon.com/dp/B012U1VVD6/ref=cm_sw_r_cp_api_i_1PEUDbR6S39EK cutting 10-12" circles all over the house... Like I said Swiss cheese. Thankfully as part of the deal I told them they had to hire their own drywall guy.
Maybe this, but it is really not good with hand held drills

You can use one of these to cut round holes. It'll cut perfectly round holes and even stepped mounting holes for flush mounting drivers. http://www.amazon.com/Hole-Pro-T-200-Adjustable-Cutter/dp/B012U1VVD6/ref=sr_1_10/175-8260483-6063160?s=power-hand-tools&ie=UTF8&qid=1458906927&sr=1-10 This is the first link I found, they aren't all nearly that expensive and you don't need a version with a dust catcher.
Make sure the cutting heads are exactly the same distance apart from the central bit. Go slowly and you get perfect results.
